Military Collections in Sweden – Second Chapter

Visiting southern Sweden offers many opportunities to dig into the rich military history of this beautiful Country in Scandinavia. As pointed out in the initial chapter on this topic (see this post), after centuries spent in assuring a stable and strong position in Northern Europe, often times with the help of a powerful military, Sweden managed to keep a neutral role in all major conflicts raging over the continent in the 20th century. While avoiding to openly taking the parts of any of the foreign contenders, in order to defend its territory and its neutrality policy, Sweden invested much in the development of national technology and in the military field.

This process was successful, resulting in a gallery of interesting and original industrial products introduced over the years, especially (yet not only) in the field of defense. Among the most tangible outcomes of this push, considering the years of the Cold War, are the unique Swedish school of aircraft design, culminating in the SAAB aircraft dynasty, as well as the establishment of factories manufacturing field weapons or land vehicles for all purposes, notably ranging from cars for everyday use to heavier armored vehicles, which are still in business today.

Of course, this development process profited from contacts with the West, especially Britain, France and the USA. For instance, in the post-WWII years, selected jet engines, missile systems or tanks were purchased from the West. Interestingly however, after the end of the Cold War, some surplus material of Soviet production, coming from newly opened borders, ended up in the inventory of the Swedish military. This reflects the often pragmatic philosophy behind procurement, usually adopted by the Armed Forces in this Country.

For those with an interest in the rich military history of Sweden, several collections can be found in the southernmost part of its territory, which is coincidentally the easiest to reach and visit from continental Europe. These collections, often actively supported by groups of enthusiasts, offer a glimpse of the technical and military tradition of this welcoming Country.

In this chapter, two of the most prominent museums in the area dedicated mostly to artillery are covered, with photographs taken from a visit in 2024.

Sights

Hässleholms Museum, Hässleholm

The exhibition of the Hässleholms Museum merges a few thematic collections, gathered and carefully maintained by local groups of enthusiasts. The topics are mainly technical vehicles of the Swedish Armed Forces – including armored vehicles, field transport vehicles, trucks, field kitchens, jeeps, special purpose trailers, etc. – and vehicles for the fire brigade. In addition, the museum has on display weapons, technical gear and training material employed by the Army.

It is actually from here that the exhibition starts. Support material like transportable field kitchens, including one from WWII years, and a portable forge for processing horseshoes are on display, within nice full-scale dioramas portraying scenes from different ages.

Training material include medical material and a rig for simulating a reanimation maneuver on a human body. Further medical gear includes many items for field surgery, as well as a diorama of field surgery room set up in a tent.

A huge, super-interesting collection of training plates is on display – really rare in this size. Plates are typically employed for illustrating the assembly of mechanical systems (weapons, on-board systems of vehicles or aircraft, etc.), or to shortlist the basic characteristics of enemy vehicles. Most of these clearly date from the Cold War era, and refer to military material from those decades.

Original cases with figurines to recreate tactical scenarios, for operation planning or training purposes, make for an unusual display. Similarly, reviews and brochures covering topics of military interest, as well as vehicle recognition charts in Swedish language (in this language are also the training plates) are unusual items to find.

Some of the plates explain what to do in case of a nuclear attack, or one carried out with chemical agents. These plates are displayed together with protection gear, mostly gas masks, and antidotes – including an automatic syringe for injecting the neutralizing agent for nerve gas (atropine)!

Artillery weapons, like special grenades, shoulder launchers, and various types of mines and standard cartridges, are displayed as samples in convenient display cases.

Even a few fragments of the Third Reich battleship Tirpitz, sunken in northern Norway, ended up here – as well as in many other military museums in Scandinavia (see this post). These armor pieces have been employed for testing some type of ammunition. The thickness of this armor is always impressive!

A gallery of uniforms, including personal light weapons and technical gear (like skis or portable aiming devices) conclude this part of the exhibition.

The collection of military vehicles takes two adjoining hangars. It is particularly appealing for technically-minded people, since it looks like mechanics workshop, with a mixture of assembled and disassembled vehicles, allowing to see the inside, as well as the on-board sub-plants.

Armored vehicles on display are really many. Among the most massive are a Centurion battle tank, and a recovery vehicle for the same type. This highly successful British tank has seen extensive and prolonged use by the Swedish Army from the early 1950s to the 1990s, when it was phased out in favor of the German Leopard heavy tank. Depending on the variant, the Centurion was attributed several code-names in the Swedish inventory, namely Strv 81, 101, 102 and 104 (Strv standing for Stridsvagn, the Swedish word for tank).

Ahead of the tank, you can see its very power train, composed of the mighty Rolls-Royce Meteor, 27 liters V12, 650 hp engine, and the Merrit Brown Z51R transmission gearbox. The recovery vehicle is roughly as massive as the tank itself.

Close by the Centurion, another sizable item is the armored bridging vehicle Brodbandvagn 971 (aka Brobv 971), which is the Swedish inventory name for what is actually a GDR-designed machine! Looking for a bridging vehicle compatible with the weight of the Leopard tank, a relatively cheap alternative was found in the BLG-60 model, originally manufactured by the German Democratic Republic (GDR) modifying the blueprint of the Soviet T-55 tank, and later sold as surplus by reunified Germany. Roughly half of the 32-units batch got from Germany in 1999 is still preserved today in Sweden, including the exemplar on display here.

The bridge span is 20-m when deployed, and the top load is 50 tons (actually a bit short of the weight of a Leopard tank…).

Next, a rare sight here is the Rlpbv 4014 radio link armored track vehicle. Again, this was originally an East German tank purchased as surplus by Sweden. It was modified in that instance from the original Soviet design (named MT-LB) into a signal relay platform, supplied with parabolic antennas. The latter were removed from the tank upon retirement, which took place by 2011, together with all technical gear. Only a few machines were sold to Finland at the time, and the exemplar in the museum is the only surviving of this specific type in Sweden.

Close by are a Pbv 301 and a Pbv 302 armored and tracked infantry fighting vehicles, designed and largely employed by Sweden. Pbv 301 dates from the 1960s, and was superseded by Pbv 302, eventually manufactured in more than 600 exemplars during the Cold War and employed uniquely by the Swedish Army until retirement in 2014.

Bigger and heavily armed vehicles are interspersed with service vehicles, typically designed in Sweden, or propelled by Swedish engines. These include a trucks with cranes, field ambulances, technical wagons with tooling for repairs carried out in the field.

Motorcycles are well represented too, some of them with interesting side skis, installed for advancing on snowy terrain.

A rather unusual sight is a full-scale field bakery! This is composed of a trail to prepare bread dough, and a big bakery oven. This and similar components of military supply, albeit often overlooked, are actually crucial in real operations, just like field guns and armored tanks – a quote attributed to Napoleon actually tells ‘An army marches on its stomach’!

Smaller items on display in the same area include several types of engines, presented on transport cases, attached to testing rigs etc. These engines range from Volvo to some US manufacturers, and include marine engines, tank engines and gas generators.

Another highlight of the show is a Stridsvagn 103. An original Swedish design from the 1980s mostly intended for domestic supply in consideration of the characteristics of the Swedish territory, this tank is designed for a crew of three, but conceived to be optionally fully operated by a single crew. It is equipped with a blade to prepare a dugout, thus converting into a field cannon, and it is able to move in shallow waters. The only limitation is in the lack of a turret, which is traded-off for a better compactness and low-rising side section, which in turns makes this tank less exposed to enemy fire especially on uneven terrain, where chance of hiding is higher.

Beside the tank, it is possible to see the engine, and the corresponding tank-trailer and support vehicle, a tracked vehicle itself called Bgbv 82, and obtained as a modification of the Pbv 302 (see above).

Nearby, several technical vehicles, including trucks and trailers (some with provision made to carry skis!), can be checked out as well.

An interesting Swedish vehicle here is a tracked anti-aircraft missile launcher, model Lbrbv 701 manufactured by Hagglunds. The main weapon is the surface-to-air missile Robot 70. The aiming device is particularly prominent to the front of the vehicle.

An array of three anti-tank machines is presented next. The first is a tracked anti-tank missile carrier, named Pvrbv 551, and originally capable of carrying 8 anti-tank missiles, shot from a single barrel on top of the tank. The second is a wheeled vehicle, named Pvpjtgb 1111 and manufactured by Volvo. This still carries a 9-cm recoil-less gun, and it was supplied with 8 shots. The third is a Pvpjtgb 9031, an even lighter vehicle from the 1960s, featuring again a 9-cm recoil-less anti-tank gun.

A few tanks designed in Sweden conclude the display in the first of the two dedicated hangars. On the two extremes of the same row are a Strv 74 and an older m/38, aka L-60. The former was a light tank developed in the late 1950s by physically modifying older m/38 models (both types were manufactured by the Landsverk company in Sweden), and kept in service until the 1980s.

In between these two tanks are displayed a Strv m/42 and two exemplars of the self-propelled cannon m/43, respectively a tank-destroyer version (Pvkv m/43) with a prominent 7.5 cm anti-tank gun, and anti-aircraft version (Lvkv m/43), featuring a 40 mm twin-barreled anti-aircraft gun.

The second hangar has in store a rare Strv m/40, developed during WWII based on the m/38 (see above). All other vehicles on display are wheeled. These include the Tgbil m/42, a 4×4 armored transport. This vehicle is an impressive Swedish design (with several big names involved in the design) enjoying an incredibly long career, spanning from WWII to the early 21st century through several upgrades and modifications.

Another iconic Swedish design by Volvo is the TP21, an off-road personal transport vehicle, originating in the 1950s from the successful PV800 civilian series by Volvo.

Also in this area field kitchens are on display, together with trucks, tractors and other technical vehicles.

The final indoor component of this impressive collection is made of vehicles belonging to the fire brigade. The crucial role of firefighting was made even more complex back then, due the limited supply of pressurized water on the territory, as well as the use of wood as the basic material for construction, and of open fire for many more uses than today.

The earlier vehicles are mostly carriages or cars converted for carrying small pumps, evacuation ladders and water hoses.

More modern vehicles on display are mostly US-designed types (Ford, Chevrolet).

The collection in Hässleholm is completed by a few items sitting outdoor. These include a Volvo P210 transport van, a red Hägglunds Bandvagn 206 – a marvelous and very successful multi-purpose, all-terrain tracked transport (see also this post) – and a Brobv 941, a bridge-layer vehicle introduced in the 1970s and in service until the end of the Cold War to support operation of the tank units of the time.

All in all, this museum is an unmissable stop for those in search of an insight on the history of artillery and military technical production of Sweden.

Getting there and visiting

The museum is located on the eastern side of Hassleholm, a peaceful village in the southernmost region of Sweden. The exact name and address is Hässleholms Museum – Norra Kringelvägen 9, 28141 Hässleholm. Large parking on the inside apron. There is a little cafe inside, and a little shop. Visiting might easily take about 2 hours for an interested subject, reading the documentation and taking pictures.

The website, in Swedish language, but pretty self-explanatory at least for the most relevant visiting information, can be found here.

Artillerimuseet i Kristianstad, Kristianstad

The Museum of Artillery has been established in the southern town of Kristianstad, for roughly two centuries the home of the A3 ‘Wendes’ Artillery Regiment. This was originally formed in 1794, and stationed permanently (partly or entirely) in Kristianstad since 1815 until 1994, with disbandment following in the year 2000.

The collection is physically hosted in a few low-rise buildings and depots. Most of them are accessible on a self-guided base, where a couple of them can be visited only on a guided tour.

The building where the ticket office is has on display some interesting communication equipment, including encryption gear, retracing the history of military communication in Sweden from the end of the 19th century to the full span of the Cold War.

Most of the consoles are made in Sweden, but some made by Nokia, Philips or Siemens are similarly on display. In the same room the history of grenade construction is illustrated, through relevant specimens of shells and cartridges.

An adjoining building is employed for gatherings by veterans, sympathizers and preservation groups, and usually showcases an annual temporary exhibition. At the time of my own visit in 2024, the theme of the exhibition was the combat-readiness in Sweden, from WWII onward.

The other buildings are former depots, and offer a wide range of artillery pieces and military vehicles, covering the history of artillery warfare in Sweden.

The artillery pieces on display in a first depot are from the 19th century. They include some very interesting one-of-a-kind exemplars, for example a French cannon from Napoleon’s army! The iconic ‘N’ mark of the French Emperor is still intact on top of the barrel.

Another interesting item is a rocket launcher, made in Sweden from 1832, and cloned from an earlier British model. This early system, well ahead of its time as a concept, was not satisfactory in terms of field performance, thus it was phased by 1846. Additionally, an early multi-barreled gun from 1875 has been restored by volunteers to an almost pristine condition.

An experimental recoil-suppressing gun carriage, with a prominent metal spring integrated in the structure, is on display along with many pieces which allow to appreciate the gradual improvement in the technology of field guns over the 19th century.

The exhibition on artillery pieces is continued in another depot, mostly with horse carriages, needed for the movement of artillery, as well as with position artillery. The big calibers here, mostly made in Sweden, offer a very complete display of the catalog of guns employed for defense. Typically too heavy for quick repositioning, the purpose of this type of gun was that of defending fortresses or coastal positions.

Moving on to the last two depots, these deal mostly with the Cold War era. In a first one, artillery technology from the Cold War era is on display, including guns, as well as tons of technical devices for aiming, communicating, taking field measurements, etc.

Among the artifacts on display is an original camera for reconnaissance troops, as well as incredible traces of an espionage operation! You can see two maps of the same location, one released by Swedish authorities, the other by the Soviet Union. The latter is clearly way more accurate than the former, when it comes to describing a site of military interest, undisclosed on the Swedish map. Based on the date of the Soviet map, the espionage activity must have taken place in the early 1960s, at the height of the Cold War.

A diorama displays a reconstruction of an entrenched observation post.

Two adjoining dioramas reproduce a fire control post and a gun emplacement for a 10.5 cm howitzer. This design from 1940 saw action well into the 1960s and the Cold War, which is the time of the gun emplacement diorama. Notably, a muzzle velocity measurement system is mounted on the cannon.

Measuring atmospheric conditions in the field is an often overlooked component of artillery action, but it is actually crucial when good precision is required for a hit. Especially when a cannon is capable of hitting way ahead of its muzzle, a good knowledge of the state of the atmosphere – including wind intensity and direction, as well as the temperature and other properties of air – between the cannon and the target is totally relevant for accurately computing the trajectory and hit point of the shell. For example, a substantial error of some hundred meters on a hit may result for a shell travel of 20-30 km, typical for a high-performance field cannon of the Cold War, even for a mild wind below 10 knots.

An aiming system PE07/R based on a radar and a balloon with onboard sensors is on display, intended for the 10.5 cm howitzer.

A much more modern weather radar and fire control station for the Bofors 15.5 cm FH77A field gun can be similarly checked out. Dating from the 1970s and the early digital era, this original Swedish system offered improved range (almost 20 km) and accuracy with respect to all previous models.

Two exemplars of the FH77A gun are on display as well! The cannon had a good maneuverability and autonomy of motion. It could be transported on longer distances coupled to a Scania 411 truck, also on display.

In the same room are a French 15.5 cm cannon, acquired in the 1950s, and a much older Krupp 21 cm howitzer. The latter, a German design from 1917, represents the top caliber ever pressed into service by the Swedish artillery, and saw action in Finland, where it was leased out during WWII (see this post).

A bit of an outlier here is a diorama of a cavalry charge from the 19th century – which is however impressively well-crafted!

The last depot is especially lively in the summer, when vehicles mostly preserved in fully working conditions are taken out on the apron! Anyway, the depot is also interesting as a static display, with many well preserved items, all formerly in service with the Swedish armed forces.

These include first a full range of motorbikes, some of them today rather sought-after classics! They are notably of different makes, including British makers like BSA, Triumph and AJS.

A self-propelled, tracked 15.5 cm cannon, listed as Bkan 1A in the inventory of the Swedish Army and made by Bofors in 1965, stands in front of an older m/43 self-propelled gun, from 1943.

A PBV 301 armored transport and a Caterpillar bulldozer frame an interesting Radiobandvagn 203B. This articulated tracked vehicle resembles the Bandvagn 206 (see above), but it was manufactured by Bolinder Munktell, Sweden. It dates from 1967, but the Volvo engine looks like brand-new!

A US-made Dodge T214, a highly successful machine produced in more than 250,000 units, is on display in its original late-1940s Swedish camouflage. Sweden acquired more than 200 of these utility vehicles from a surplus deposit in France, after WWII.

An example of Pvpjtgb 9031, with its distinctive recoil-less anti-tank cannon, and a Pbv 302 (see above), are on display alongside many military transport vehicles, mostly made by Volvo.

An interesting item is a gas generator designed by Ford, yet bearing Swedish labels, hence likely intended for the Swedish market. This device could employ wood or charcoal to produce gas, which when suitably processed through heat-exchangers, can be employed to run an internal combustion engine. In an emergency situation, like when facing a shortage in oil supply, this type of device can be profitably employed to propel vehicles. This was a rather widespread option during WWII. Bulkier designs can be employed for running larger piston engines, e.g. for electric power production.

On the apron between the depots, more vehicles and guns can be found. Some of them are typically recovered under a roof in the winter, to be taken out in the good season. These include perfectly working examples of a Volvo TP21 military transport (see above) – a predecessor of the modern XC90 SUV! – and a massive Volvo HBT artillery tractor. This half-track vehicle was based on a German design. It was built in Sweden in roughly 100 units, and employed for transporting troops, as well as cargo, including cannon trailers or self-propelled cannons. The speed of each track is controlled together with the direction of the front wheels by the pilot’s yoke, allowing for an easier steering action.

Finally, a few more guns are on display outside, including a rare m/1946 multi-barreled cannon made by Bofors, and even a Soviet 12.2 cm gun m/1932-1937, largely employed within the Soviet Bloc, from Stalin’s era to the 1990s, and donated by a Czech artillery collection to the Artillerimuseet.

Getting there and visiting

The Artillerimuseet can be reached at the address Köpingevägen 86-30, 29163 Kristianstad, which corresponds to a nice countryside location, roughly 3 miles south of the small center of Kristianstad. Access is via a short unpaved road, and the parking area inside is very convenient.

The place is run by knowledgeable volunteers, mostly former military staff. A visit of what is described here, which corresponds to what you can see on your own without a guide in the good season, may take about 1.5-2 hours for an interested person.

Please note that the cashier accepts only cash (possibly other forms of electronic payment available for Swedish residents). The website (mostly in Swedish) with full information is here.

Herdla Torpedo Battery – Defending Bergen in WWII and the Cold War

Despite overshadowed by the natural beauties of Norway, the heritage of the rich war history of this Country would really deserve a dedicated trip. Thanks to its geographical location, this Scandinavian Nation had a primary strategic role both in WWII and the Cold War.

Hitler’s Third Reich military forces conquered Norway early in WWII (Spring 1940), gaining an effective stronghold for launching sea and air patrolling missions over the Norwegian Sea and the northern Atlantic. The long coastline stretching from the Skagerrak strait up to North Cape was made impenetrable to enemy invasion, building anew a capillary network of fortifications – the Atlantic Wall. This masterpiece of military engineering was based on an extensive catalog of reinforced concrete standard elements (Regelbau in German), ranging from fortified casemates to radar towers, to observation and target range finding stations, to bunkerized gun batteries, etc. These elements were assembled in larger fortified compounds, placed in key strategic locations along the coast or in the narrow firths reaching to major ports and towns, like Bergen or Trondheim.

Typically run by the Kriegsmarine (Navy) or Luftwaffe (Air Force), these forts may comprise measuring stations, anti-shipping guns, anti-aircraft cannons, plus barracks, services, ammo storages, and even airfields in some cases. They were built not only in Norway, but having been originally planned by the Third Reich to protect the entire coast of conquered continental Europe, they were erected along the shoreline also from Denmark down to France.

As a matter of fact, many of the Norwegian fortresses of the Atlantic Wall rank today among the most massive and well-preserved of the entire line (see here for some highlights).

But the war history of Norway, and of its mighty military infrastructure, didn’t stop with the end of WWII. With the start of the Cold War, Norway became a NATO founding member, and once again of great strategic value. It found itself in close proximity to the USSR, and with a long coastline facing the sea corridor taking from the highly-militarized Murmansk and Kola Peninsula (see here) to the northern Atlantic.

Most of the Atlantic Wall forts, especially anti-shipping and anti-aircraft gun batteries, were obsolete by the 1950s, and were soon deactivated. Some were abandoned or, when retained by the Norwegian military, they were modified to cover new functions.

In a few cases, the original mission of the site by the Third Reich was retained by NATO forces in the Cold War. This is the case of the torpedo battery in Herdla.

The fortress of Herdla was a major strategic fort in the Atlantic Wall, allowing to keep a watch on the entry point to the inner waters leading to the large industrial and military port of Bergen. Thanks to the morphology of the area, featuring a rare spot of flat land nearby a steep and rocky cliff, an airfield was installed by the Third Reich besides a set of bunkers, effectively hidden in the rocks. A land-based torpedo battery, consisting of a range-finding and aiming station and torpedo-firing tubes, was part of the fort.

During the Cold War, it was decided that the torpedo battery could be still a valuable asset, and Herdla was retained by the Norwegian military – by comparison, the airfield, too short for the requirements of the jet-era, was not. Over the years, the torpedo battery was potentiated to keep up-to-date against the technological offensive capabilities of the Eastern Bloc, and to exploit the most modern identification and surveillance techniques.

The torpedo battery was part of a larger naval fort, which controlled also the barrier of sea mines implemented to stop a sea-based intrusion towards Bergen.

As a matter of fact, the area control functions and the offensive capability of Herdla were retained until the early-2000s, when the fortress was deactivated following the end of the Cold War and defense budget cuts.

Luckily however, the often neglected Cold War chapter of warfare history has in Herdla a valuable asset – an accurately preserved fortress regularly open for a visit. A modern visitor center welcomes the more curious travelers, leaving Bergen towards the remoteness of the coast. It retraces the WWII heritage of the Herdla site, thanks to an exhibition centered around an original Focke-Wulf FW190, recently salvaged from the bottom of the sea, and with a special history to tell. Then a visit to the battery, looking like it had just been left by the military staff, is a unique emotion for both the specialized war technology enthusiasts and the general public as well.

The following report and photos is from a visit taken in Summer 2022.

Sights

As outlined in the overview, the Herdla site today is centered on two major highlights. One is the visitor center, with the preserved relic of a unique Luftwaffe Focke-Wulf FW190. The other is the former torpedo battery and Navy area command bunker, Norwegian facilities installed during the Cold War in bunkers dating to the Third Reich era.

Visitor center & Focke-Wulf FW190 exhibition

The relic of a Focke-Wulf FW190 A-3 German fighter from WWII is hosted in a dedicated room, where a scenic lighting makes this impressive exhibit literally shine.

This exemplar of the iconic Third Reich fighter, produced in some thousands examples, and now almost impossible to find especially in Europe, is ‘Gelbe 16’ (which can be translated in ‘Yellow 16’) of 12./JG5, and its history is deeply related to Herdla.

It took off on December 15th, 1943, from the airfield the Luftwaffe had established on the flat area now lying ahead of the visitor center, at the time a very active German airbase.

Following troubles with the engine, it ditched in the cold inner water near the island of Misje, some ten miles south of Herdla, the pilot being able to abandon the doomed aircraft, and being saved by local fishermen – and returned to the Luftwaffe, who had a Norwegian resistance prisoner released in acknowledgment.

The aircraft sank to the bottom of the sea, but its memory was not lost by some of the locals, who clearly remembered the events. The Focke-Wulf remained there for 63 years, but it was finally located and pinpointed by the Norwegian Navy, instigated by local interest, in 2005. After preparatory work – including exploration dives, to assess the condition and to set-up recovery operations – the fairly well-preserved wreck was lifted to the surface on November 1st, 2006, and loaded on a tug. Conservative restoration work then took place in Bergen.

Instrumentation and the machine guns were all recovered, together with many further fragments of equipment. Interestingly, evidence of repaint was found during conservation, retracing some previous assignments. Yet the history of this very exemplar remains difficult to write in its entirety.

Finally, following completion of conservation works, a new home for the aircraft was prepared in Herdla, where a hangar was built anew – and this is where you can see it today.

The aircraft is in an exceptional state of conservation, considering it spent 63 years in sea water. The fuselage, wings and tail are not significantly damaged, with just some paneling having disappeared on tail control surfaces, due to corrosion. The swastika on the vertical stabilizer is still perfectly evident, like other painted details.

The propeller blades are all bent downstream, as typical for an emergency landing carried out without the landing gear and the engine still running. The tail wheel is there with its original tire, the emblem of the German brand ‘Continental’, still in business today, being clearly noticeable.

The instrumentation from the pilot’s control panel has been put on display separately. Also a gyroscope has been found. Everything is only slightly damaged. Similarly, the two machine guns, dismounted prior to lifting the aircraft from the sea, are little damaged, and displayed with some ammo.

Complementing the exhibition are a few other pieces from other wrecks, as well as some quality scale models and dioramas portraying Herdla in the days of Third Reich tenancy.

Torpedo Battery

Access to the torpedo battery, which was built in WWII just above sea level, is from a gate on the land side. From outside, the bunkers in the fortress of Herdla appear especially well-deceived in the rocks of the cliff.

What is seen today inside, however, dates to the years of Norwegian tenancy. The facility was updated in several instances during the Cold War, the last in the 1990s. Immediately past the gate, you get access to a modern and neat mechanics shop, where a partly dismounted torpedo allows to have a suggestive look inside this marvelous weapon.

Interestingly, Norway inherited and went on operating a significant number of German G7a (TI) torpedoes. This was the standard torpedo employed by the Kriegsmarine since 1934, and with some modifications (‘TI’ standing for ‘first variant’, the later variants bearing other codes), for the full span of WWII.

Propulsion power for this torpedo was from a piston engine, fed by high-pressure vapor obtained by the combustion of Decaline with compressed air stored onboard, mixed in a heater (i.e. a combustion chamber) with fresh water, similarly stored in a tank. The resulting mixture fed a 4-cylinder radial piston engine, driving two counter-rotating propellers. The exhaust in the water produced a distinctive contrail of bubbles, and the presence of a high-frequency moving mechanism had the side-effect of a significant noise emission. The head of the cylinders can be clearly seen in the dismounted exemplar.

Guidance was provided by rudder steering controlled with the help of gyros, whereas depth was controlled via a mechanical depth sensor. The torpedo could stay close to the surface or keep an assigned depth. In WWII the torpedo had no homing device – i.e. it was ‘blind’, thus requiring carefully putting it on a target-intercept trajectory. It could however cover pre-determined trajectories of some sophistication. The set-point selection for guidance and the yaw regulation gyro assembly have been taken out of the torpedo, and can be checked out in detail.

The range could be selected before launching, and was traded off with speed. It could be between 5.500 and 13.200 yards, and the speed ranged between 44 kn and 30 kn correspondingly. The German origin of the torpedo on display is betrayed by the writings in German on some parts.

Leaving the workshop through a gate towards the inner part of the bunker, a roomy supply storage area can be found, with some interesting material including torpedo parts, as well as a torpedo launching cannon.

This item represents the primary way of launching torpedoes in the early Cold War from land-based batteries or ship decks. This was a technology inherited from WWII, when coastal batteries of the Atlantic Wall ejected torpedoes from slots in the bunker wall, shortly above the surface of the water, employing cannons similar to this one (which dates from the Cold War period), thanks to a burst of compressed air. This cheaper, but less ‘stealthy’ and accurate launching procedure, was replaced by underwater launching tubes only over the years of the Cold War, featuring an increase in the level of sophistication of warfare. Correspondingly, the slots in the side of the torpedo battery bunker facing the water were bricked up, and torpedo cannons were retained mostly for use from the deck of warships.

From the storage room you get access to the core area of the battery. This is through a decontamination lock, with gear for anti-contamination testing, including paper strips for checking contamination from poisonous gas.

The battery features two diesel generators for electric power, employed in case of disconnection from the regional grid.

Less usual – for a military facility – is the presence of two air compressors. Compressed air is relevant for torpedo operation, being employed for the launch burst from the torpedo tube, as well as for propulsion and gyros in the G7a torpedo. The air compressors in Herdla are made by Junkers, solid German technology from 1961!

A few bunkerized resting rooms for the staff manning the battery can be found in the same area, besides the power/compressed air supply room and the torpedo room. The resting rooms are minimal as usual, with suspended berths, and much personal military equipment on display – coats, blankets, medical kits, and more technical material.

Finally, the core of the battery is the torpedo room. This is much longer than wider, access is via the short side. In the Third Reich years, the launching slot was on the short side to the opposite end of the room, right above the water. Today, this slot has been bricked up, and there is no window at all.

The torpedoes are aligned on racks along the long sides of the room. The launching system is via two underwater tubes, which are accessed via obliquely mounted hatches, one to each side of the room at the level of the floor. The section of the racks closer to the entrance door is actually a pivoting slide. The slide could be pitched down, thus allowing the torpedo to slip through the hatch in the firing tube. The original launch control console can be found to the right of the access door – in a mint condition, it looks really like it had just been put in standby following a drill!

Over the years, the stockpile of G7a TI torpedoes was upgraded especially in terms of guidance. The major modification was the adoption of wired control. This is based on a thin electric cable unwinding as the torpedo proceeds along its trajectory, keeping it linked with the launching battery. This upgraded model is called G7a TI mod 1. Control via a steering joystick and trajectory monitoring system could provide manual guidance to the torpedo, thus sharply increasing the chance of target interception. This technology is still in use today. Wire tubes can be found on top of the rudder of torpedoes.

Besides the G7a, Herdla battery received the TP613 torpedo, a weapon developed in Sweden in the early 1980s from previous designs. Exemplars of this torpedo, still in use, are visible in the torpedo room. In terms of mechanics, the piston engine of this torpedo is powered by the reaction of alcohol and Hydrogen-peroxide. In terms of guidance, this torpedo features improved wired communication for guidance and power setting (i.e. changing torpedo speed during the run), as well as passive sonar homing. A dismounted section exposing the engine can be found on display.

The wire tube installation on top of the rudder is featured also on this model, and examples of the wire are on display.

The original guidance console, made by Decca, with a prominent joystick on it, is on display as well!

Training and proficiency checks are typically carried out without a warhead, but with an instructional head. Distinctively painted in shocking red, and with powerful lights in them – to show their position to simulated targets during training exercises, when needed – these are on display in a number. Since the torpedoes, just like missiles, are very expensive, a way of recovering them after instructional use has been envisioned, in the form of inflating bags coming out of the head, increasing the buoyancy of the emptied torpedo and forcing it to surface when reactants tanks are empty and power is off.

Offensive warheads can be exchanged with dummy ones for training, bolting them to the body of the torpedo, which remains totally unchanged. A warhead with a 600 lbs explosive load, triggered by a proximity pistol, was typically put on G7a torpedoes. The proximity pistol was made of four petals, which on contact with the target were bent towards a conductive metal ring around the nose cone of the torpedo, closing an electric circuit and triggering the explosion.

Leaving the torpedo room and the bunker is via the same way you came in.

Sea Mines & Area Control Center

But your visit is not over. As mentioned, the Herdla coastal battery hosts an area control center, with provision to manage target detection facilities and the minefields in the waters around Bergen.

This part was built in a facility strongly potentiated with tight doors, typical to the shockwave-proof military construction syllabus of the Cold War. A sequence of roomy vaults carved in the rock hides a number of containerized modules, together with an exhibition of sea mines and related apparatus.

Most notably, an L-type Mk 2 moored mine and a Mk 51 bottom mine are on display, with a understated control panel. The latter is actually a portable controller for triggering the mines. Already before WWII, sea mines were often put on the bottom of the sea in shallow waters, or moored in deeper waters, to control access inner waters, firths, ports, etc. The Germans made extensive use of this technique in Norway, and following WWII this strategy was inherited by Norway to protect its waters from (primarily) Soviet intrusion.

Despite contact mines were still popular in WWII, they have been surpassed and gradually replaced already in that age by proximity mines, based on noise and – especially – magnetic sensors. Today, proximity fuses activated by the magnetic field of ships or submarines passing nearby are standard technology. Onboard electronics allows to distinguish between the magnetic signature (i.e. fingerprint) of different ships, thus avoiding any issue for civilian or friendly traffic, and activating only against enemy shipping. Degaussing techniques – i.e. the ability of military ships to hide their signature – have forced to improve detection technology, which is today extremely sophisticated.

Furthermore, for the protection of ports and friendly waters, sea mines are typically controlled and triggered by hand, upon detection and localization of enemy shipping, by means of dedicated detection facilities on land or water. This improves precision and allows more flexible defensive-offensive tactics, since a human chain of command has control on the minefield, instead of a pre-determined computer program.

To trigger the mines, consoles like that on display are employed, where a trigger for each mine allows precise control over the minefield.

The first containerized control center hosts a similar, yet much more modern, dedicated console. Everything in this movable control center is very neat, and really looking like reactivation might take place in just moments! Of interest is also the situation map, covering the area around Herdla and the water inlet to Bergen.

A nearby container reveals berths and a small living area for stationing staff.

Yet another container hosts a complete situation room covering the area. Similar to the coastal battery in Stevnsfort, Denmark (see here), a careful eye was constantly overlooking the shipping in the area.

In the same container, a console for steering torpedoes, more modern than that previously seen in the torpedo battery, is on display.

All in all, Herdla is a one-of-a-kind destination, of primary interest for those interested in Cold War military history, enjoyable and easy to visit. Totally recommended for everybody with an interest in history, with much to see and learn for the kids as well.

Getting there & Visiting

Herdla fortress features an official visitor center with a large parking area, and amenities including a small restaurant and a shop. The official website is here. It can be reached about 27 miles north of central Bergen, roughly 45 minutes by car. The address is Herdla Museum, Herdla Fort, 5315 Herdla.

The torpedo battery and control bunker can be visited only on a guided tour. Visiting from abroad, we scheduled an appointment, and were shown around by the very knowledgeable guide Lars Ågren, a retired officer of the Royal Norwegian Navy. He joined the Navy in the late 1970s, in time to gain a substantial, hands-on Cold War experience during the final, high-tech part of that confrontation. He was promoted to tasks in the NATO headquarters in Belgium, later returning to Norway, and totaling more than 37 years in service. He is strongly involved in the management of the Herdla site. Chance is for you to embark on a visit with this guide, or other very competent guides who will satisfy the appetites of more committed war technicians and engineers, being capable of entertaining also the younger public as well.

A visit to the torpedo battery and control center may last about 1 hour. Seasonal changes to opening times may apply, as common in Northern Countries, therefore carefully check the website.

Aircraft Carriers of the West Coast

Among the countless interesting places and sights the States of the West Coast have to offer, even aircraft carriers need to be mentioned. There are three ‘capital sites’ that will surely appeal to war veterans, pilots, seamen, historians, technicians, children and everybody with an interest for ‘CVs’ – an acronym for ‘carrier vessels’. Two are super-museums in California, where the USS Hornet and USS Midway are permanently preserved and open to the public, and a third is the Naval Shipyard in Bremerton, Washington, which is an active installation of the US Navy in the premises of the Naval Base Kitsap, where maintenance work is carried out on the current CV-fleet, and where part of the reserve fleet – including most notably some aircraft carriers – is moored.

Here you can find some photos of these sites from visits of mine in 2012 and 2014.

USS Hornet (CV-12) – Alameda, CA

This ship is an Essex-class carrier commissioned in late 1943. Since then, she saw extensive action throughout WWII in the Pacific theatre, being involved in frontline operations leading to the defeat of Japan. As a matter of fact, aircraft from this ship totalled a number of downed aircraft ranking second in the general list of aircraft carriers of the world, behind USS Essex – which enjoyed a full year of service more than Hornet during the war with Japan.

The original appearance of the ship was much different from today’s, first and foremost due to the straight-deck construction of the Essex-class – just like all other carriers until the Fifties. For Hornet the current shape of the deck is the result of SCB-125 modification in 1956, introducing an angled landing deck. This feature, which came along with other major changes to the overall structure also resulting in a significant weight increase, allowed independent take-off and landing operations. Differently from other ships of the class, Hornet wasn’t upgraded in the late-fifties with steam-powered catapults, retaining hydraulically powered ones instead, thus being incapable of launching heavier aircraft like the Phantom, Intruder, Vigilante, or even the Hawkeye. It was then assigned to a support role as an ASW carrier, equipped with Tracker aircraft and helicopters for anti-submarine missions.

In the late Sixties Hornet was involved in the race to the Moon, serving as a rescue platform for the first moonwalkers returning from the succesful Apollo 11 mission, and subsequently in the same role for the astronauts of Apollo 12.

Similarly to all other Essex-class vessels – with the exception of the venerable USS Lexington, operated as a training ship until late 1991! – it saw limited action in the Vietnam War, when much larger and more suited carriers had become available for war operations, and it was retired in the early Seventies.

During your visit you are basically free to move all around the many well-preserved areas under the flight deck.

There you can see the striking proportions of this relatively ‘small’ carrier. The mechanism of the central elevator can be seen to the bow of the ship. An impressive table with the number of targets hit recalls the primary role this ship had in WWII.

On the main aircraft storage level there are some preserved aircraft, not all from the history of this unit. Among the many interesting features in this area, a replica of the helicopter which took the astronauts of Apollo 11 on board. This very helicopter was used in Ron Howard’s movie ‘Apollo 13’ starring Tom Hanks. Also the mobile quarantine facility for the astronauts can be found here. Neil Armstrong’s very footsteps from the helicopter to the quarantine facility are marked with white paint.

Moving back to the stern of the ship it is possible to visit a very interesting technical area for aircraft maintenance and servicing, as well as for mission preparation. It reminds the primary role of aircraft carriers as a frontline-deployed, moving airbases, with everything that is necessary for operating the aircraft onboard on a regular basis for offensive missions. A hatch leading to the compartments on the lower levels has been left open, and this allows to appreciate the actual size of the ship, really huge, with multiple storage levels for aircraft spare parts and ordnance.

Also very interesting are the big fireproof sliding doors for cutting the aircraft storage deck into compartments in the event of fire – possibly due to some ordnance piercing the deck of the ship, as well as to accidental causes.

Further interesting sights in the self-guided part of the visit include the operational briefing room, some service rooms, dormitories and a large area for the anchor moving mechanisms.

A second part of the tour is guided. You move around is small groups and you access the flight deck and the ‘island’, the command and control center of all operations – deck management, flight mission control, and ship control & navigation. The guides are very knowledgeable and enthusiastic veterans, able to tell you detailed explanations of what you see as well as anecdotes from the history of the ship.

The Presidential Seal has been placed where president Nixon was standing to oversee the recovery of the moonwalkers from Apollo 11.

This part of the visit will be extremely interesting for more technically minded subjects – you will see original wind signals for landing aircraft, an original LORAN navigation device for sea navigation, the normal and emergency arresting systems, the Fresnel optical landing aid system, and tons of other extremely interesting items which were actually used in real operations.

From the stern of the ship and the flight deck it is possible to take fantastic pictures of downtown SFO.

Extra Feature – Treasure Island Pan Am Terminal

A little ‘extra’ you can find on your way if you are travelling from San Francisco via the SFO-Oakland Bay Bridge to the site fo the USS Hornet is Treasure Island. This artificial island was taken out of the water at the end of the Thirties for the Golden Gate International Exhibition in 1939. Coincidentally, Pan Am, which had recently inaugurated its trans-Pacific ‘Clipper’ air service with the huge Boeing 314 seaplane, built a facility on the island, with a passenger terminal and service hangars for maintenance. Operation of the Clipper were moved here for good, and the aircraft took off and alighted on water between Treasure Island and Yerba Buena Island, the smaller natural island to the south – the cove is today called Clipper Cove. Later on the service was relocated to Alameda as the island was taken over by the military.

Unlike most of the buildings dating from the exhibition, wiped out soon after it, the terminal survived and it is a proportionate, nice example of the airport building style of the late Thirties.

Also the foundations of some of the original passenger pier, as well as concrete slides for seaplane operations on the shore of Clipper Bay, can be seen still today. The Pan Am terminal building was used to simulate the terminal at Berlin Tempelhof in Steven Spielberg’s movie ‘Indiana Jones and the Last Crusade’.

Treasure Island is also a good place for taking pictures of downtown SFO, as well as the most famous items on the bay – Alcatraz and the Golden Gate Bridge.

Getting There

The ship is permanently anchored by one of the piers close to the former Alameda NAS, on the southern side of the island of Alameda. It can be reached very conveniently and quickly from downtown San Francisco via the Oakland bridge (I-80), and from Oakland, Berkeley, San Leandro and all districts on the eastern side of the bay. Full explanation and info on their website. Treasure Island is located roughly mid-way along the Oakland Bridge. Visiting the Pan Am terminal is a quick detour from the interstate. Large parking nearby both sites.

USS Midway (CV-41) – San Diego, CA

This is the first and the only remaining of the three Midway-class ‘super carriers’ – which included USS Franklin D. Roosevelt and USS Coral Sea. The origin of the class dates back to WWII, when it was decided that larger, armored, metal decks were to replace the vulnerable wooden decks of the Essex-class carriers. USS Midway was commissioned in September 1945, immediately after VJ-Day, with a straight deck, albeit steel-made. The steel construction was considered a relevant asset for jet aircraft operations, and all three carriers were kept in active service following the progressive transition to the new type of aircraft propulsion, with only minor modifications needed to the flight deck.

USS Midway was involved in the early stages of US missile experimentation, with the first tests of sea launched V-2 rocket clones, originating from the German design, and Regulus I air-breathing cruise missile.

The current shape of USS Midway is the result of subsequent major modifications. Program SCB-110 in the late Fifties added the angled deck to enhance simultaneous launch and recovery operations and flexible flight deck operations. Also the curved ‘hurricane-proof’ bow was added, together with steam-powered catapults.

In 1966 this ship was the only of the three of her class to receive the very expensive SCB-101.66 modification, resulting in a lengthening of the flight deck, the adoption of more powerful steam catapults and a new arrangement of the higher-load elevators. All three ships were on active duty in Vietnam, USS Midway apparently launching the first and last US air attacks of the war.

Even though USS Midway – the largest and best equipped of the three – could not operate the Tomcat, it could take four squadrons of Hornets, thus remaining effective in frontline service well into the Gulf War in the early Nineties, the last major operation in which she was involved before retirement and re-opening as a permanent exhibition – notably among the most popular in San Diego alongside the zoo.

Similarly to the USS Hornet described above, the tour of the Midway starts with a self-guided exploration of the aircraft storage deck and of the air deck. Among the tons of interesting sights here, to the bow you can find under the air deck the steam reservoir for the catapults and the system for moving the anchors.

Further back the main hangar for storing the aircraft is really huge. You can get an impression of the size of the ship by looking at the lower storage levels, where jet engines and air-launched ordnance are still visible.

With respect to the USS Hornet the exhibition is somewhat more ‘lively’, also with some reconstructed scenes, notice-boards, prepared dinner tables and so on. On the cons side, the place can get really crowded.

You can explore the crew areas, with dormitories, kitchens, canteens, medical services – including a fully equipped surgery compartment.

Most interesting is the propulsion system. Midway-class ships, as well as the later Forrestal-class, were all conventionally powered – non nuclear. Oil was supplied to burners, heating water and generating steam. By supplying steam to turbines mechanical power was obtained and transferred to the propeller shafts. This involved monstrous reduction gears. You can see the control room of this very complex system as well as burners, turbines gearboxes and propeller shafts, all explained with technical schemes – this will be extremely interesting for technically minded people. Close by, the similarly important air conditioning and ventilation system – an ancillary system at a first glance, it is absolutely necessary for all computers and electronics.

Other interesting sights are the briefing rooms for both flying and non-flying personnel, the chapel, and the inertial navigation system – buried close to the buoyancy center of the ship to reduce the influence of oscillations.

On the deck there is a collection of aircraft, most of them from the operational history of this unit. Also visible is the Fresnel optical landing aid.

Similarly to the USS Hornet, you can join a guided tour for a visit to the ‘island’. This is much roomier than that of the older Essex-class ship. You are provided clear explanations by very competent guides as you tour the navigation room, flight control and ship control areas.

From the deck you are offered a view of North Island NAS. Until she left for her new home port in Yokosuka, Japan, you could often see here USS Ronald Reagan (CVN-76), a nuclear powered, Nimitz-class carrier commissioned in the 2003 and home based in San Diego at the time of my visit.

Other Nimitz-class carriers are currently based here.

Getting There

The USS Midway museum is among the best known museums in Southern California, and it’s really hard to miss it due to the prominent place on the waterfront next to downtown San Diego. Large parking on the pier nearby. For planning your visit have a look to their website.

Puget Sound Naval Shipyard & Naval Base Kitsap – Bremerton, WA

The Naval Base Kitsap with the Puget Sound Naval Shipyard are major installations of the Navy. The Shipyard dates from before WWI, and albeit a small museum on the topic exists close to the ‘civil’ port of Bremerton, clearly the installation is not possible to visit, for it is surrounded by the base. Luckily, the Shipyard is neither much hidden nor far from the street running along the waterfront, and the size of aircraft carriers makes them rather difficult to deceive… This leaves the opportunity to take a look at what is moored here by simply moving around a bit in the hilly area of Bremerton until you find a suitable spot for taking pictures. You can also walk to the waterfront, and find some isolated spots from where you can take some impressive shots without even coming close to violating the perimeter of the base.

Some pictures can be taken from the sea if you are leaving or arriving with a ferry-boat.

The Shipyard is where modifications are carried out on most vessels. Besides running the Shipyard, the Naval Base Kitsap acts as a home port for some ships, including some active aircraft carriers and many submarines. The Shipyard facility has been used for storing vessels in a mothballed condition and for stripping those to be sold for scrap of some lighter hardware. The latter are those placed in the most peripheral area of the base, and the easiest to see.

When I visited in 2012 the base was very busy.

In the pictures you can see two Forrestal-class ships – USS Independence and USS Ranger – and two ‘Improved Forrestal’, Kitty-Hawk-class ships – USS Kitty Hawk and USS Constellation. As of late 2016 Ranger and Constellation have been transferred to Brownsville, TX for scrapping, while Independence is to follow and is awaiting towing for early 2017.

USS Kitty Hawk remains in a mothballed status and there is some interest to preserve it as a museum somewhere, for together with USS John F. Kennedy they remain the only Forrestal-class ships still in a relatively good shape.

The eight Forrestal/Improved Forrestal-class aircraft carriers were the first conceived with an angled deck. They constituted the backbone of the US carrier fleet of the Cold War in the late Fifties, Sixties and early Seventies, when the nuclear powered USS Nimitz was commissioned. Many of them were deeply involved in Vietnam operations. All of them remained active until the Nineties and were involved in operations all over the world, a true icon of the might of the US Navy.

Besides the mothballed or scrapyard-due fleet, you can find in Bremerton some carriers on active duty at the Naval Base Kitsap. At the time of my visit, I could see the Nimitz-class USS John C. Stennis (CVN-74) and USS Ronald Reagan (CVN-76) – the latter is the one undergoing maintenance in the pictures. Kitsap is a huge base of the US Navy, among the largest in the US, and home port for many strategic submarines.

Getting There & Moving Around

The most convenient way to see the mothballed fleet is from Charleston Boulevard, approaching from the west along the waterfront. There is chance of parking in a somewhat deserted area out of the perimeter of the base. When leaving with the ferry from Bremerton port, you are allowed a view of the easternmost part of the base.
