EKW
''Eidgenössische Konstruktionswerkstätte'' English: "Federal Constructions Works", short K+W, was a Swiss state-owned enterprise, with the aim of making the Swiss military independent of foreign sources for its equipment needs. It was established in 1867 in Thun and produced artillery, vehicles and other typical military equipment. In 1914 Switzerland put in an effort to make itself independent of foreign suppliers of military aircraft and started the production of the DH-1 in Thun. Long-standing connections to the ETH Zurich ensured the necessary know-how. 1940 the aviation department moved from Thun to Emmen and in 1943 it became a separate unit of the Swiss Armed Forces independent under the name of Eidgenössisches Flugzeugwerk (F+W) (Federal Aviation Works). The Eidgenoessische Konstruktionswerkstaette focused now on the production of armoured fighting vehicles for the Swiss Army, both of its own designs and licensed production of M113 armored personnel carriers and Leopard ...

EKW C-3600
The EKW C-36 was a Swiss multi-purpose combat aircraft of the 1930s and 1940s, built by the Eidgenoessische Konstruktionswerkstaette. It was a single-engined monoplane with a crew of two. It entered service during World War II in 1942, and despite being obsolete, remained in front line use until the early 1950s, and as a target tug until 1987. Development and design In 1935, the Swiss Air Force developed a requirement for a replacement for the Fokker C.V-E biplanes, which were used as reconnaissance aircraft, escort fighters and patrol aircraft. To meet this requirement, the Swiss Federal Constructions Works (EKW) proposed two designs, a modernised C.V, the EKW C-35 and an all new monoplane, the C-36.Gruenenfelder and Francillon 2001, p. 46. Orders for 80 C-35s were placed in 1936, but no decision was made about whether to order the C-36, with preference being given to the purchase of foreign twin-engined aircraft for the role, attempts been made to buy Messerschmitt Bf 110s fro ...

EKW C-35
The EKW C-35 was a 1930s Swiss two-seat reconnaissance biplane aircraft built by the Swiss Federal Construction Works (Eidgenoessische Konstruktionswerkstaette, K+W), Thun. Development Two aircraft were designed by the Eidgenössische Konstruktions Werkstätte to replace the Fokker C.Ve which the Swiss Air Force were using. The two projects were the EKW C-35 biplane and the EKW C-36 monoplane. After evaluation the air force ordered 40 C-35s in 1936. Additional aircraft were built from spares. The C-35 was a two-seat biplane with fixed tailwheel landing gear and conventional tail unit. The aircraft was powered by a Hispano-Suiza HS-77 V-12 piston engine (licence-built Hispano-Suiza 12Ycrs The Hispano-Suiza 12Y was an aircraft engine produced by Hispano-Suiza for the French Air Force before the Second World War.

F+W C-3605
The F+W C-3605, nicknamed ''Schlepp'' ("Tug") or "Alpine Anteater", was a target towing aircraft operated by the Swiss Air Force from 1971–1987. The aircraft was developed during the latter half of the 1960s by the Swiss Federal Construction Works (Eidgenoessische Konstruktionswerkstaette) (EKW), renamed Farner Werke (F+W) in 1972, as a conversion of the existing C-3603 ground attack/ target towing aircraft. Following a successful prototype conversion in 1968, 23 aircraft were converted between 1971–1973 with 2 still flying in private hands. Development In 1967 the Swiss Air Force determined that their C-3603-1 target-towing aircraft still had approximately 10 years of structural life remaining, but that the plane's Hispano-Suiza piston type engines were on the verge of wearing out, with replacements becoming scarce. The C-3603-1 was based on a World War II era ground attack design which had been inspired by the design of the Messerschmitt Bf 109. Evaluations of various t ...

Fliegerabwehrpanzer 68
Fliegerabwehrpanzer 68 was a Swiss self-propelled anti-aircraft gun which was tested but did not enter service. History and development In 1977, a project of Contraves AG Oerlikon-Buehrle, Eidgenoessische Konstruktionswerkstaette and Siemens was presented for an air defense shield. In 1979, the construction of two prototypes was decided in collaboration with the K + W Thun. 1979 saw the delivery of the prototypes to the Group on Arms Services. From 1979 to 1980, the vehicles were subjected to rigorous testing, but the project was cancelled in favor of the Rapier missile. The actual weapon system formed the FlaK-Turm ("Flak turret"), which came from the German Flakpanzer ''Gepard'' based on the chassis of the Panzer 68 widened by 180 mm. It mainly included the homing radar, tracking radar, the fire control with computers and the twin 35-mm weapons. The crew consisted of the commander, the gunner and the driver. The target search radar allowed a continuous and reliable air ...

Panzer 68
The Panzer 68 was a Swiss main battle tank developed by the Eidgenoessische Konstruktionswerkstaette in Thun in the late 1960s, and was the main tank of the Swiss Army until the late 1990s. History The Panzer 68 was based on the Panzer 61, which initial development dates back to 1951. The development started immediately after the successful introduction of the Panzer 61. Improvements consisted of wider tracks, stabilized gun, and the introduction of a second machine gun instead of the coaxial 20mm gun of early Panzer 61 models. In 1968 (hence the name) the Swiss parliament decided to buy 170 vehicles. Deliveries of the Panzer 68 started in 1971. In 1977 a second batch was manufactured. In the years between 1978 and 1983, a third and fourth batch followed. The last two lots were called either AA3 and AA4 or Panzer 68/75. The most important change was the introduction of a bigger turret. The Austrian Army showed some interest in the Panzer 68 in the late 1970s, but decided no ...
