British QF 3.7 inch AA - 3D printed model


This is a detailed reproduction of a British quick firing 3.7 inch anti-aircraft gun.

The QF 3.7-inch AA was Britain's primary heavy anti-aircraft gun during World War II. It was roughly the equivalent of the German 88 mm FlaK and American 90 mm, but with a slightly larger calibre of 3.7 inches, approximately 94 mm. Production began in 1937 and it was used throughout World War II in all theatres except the Eastern Front. It remained in use after the war until AA guns were replaced by guided missiles beginning in 1957.

In 1928, the general characteristics for a new HAA gun were agreed, a bore of 3.7 inches (94 mm) firing 25 lb (11 kg) shells with a ceiling of 28,000 feet (8,500 m). Financial stringency led to no action being taken until the 1930s, when the specification was enhanced to a 28 lb (13 kg) shell, 3,000 ft/s (910 m/s) muzzle velocity, a 35,000 feet (11,000 m) ceiling, a towed road speed of 25 mph (40 km/h), maximum weight of eight tons and an into action time of 15 minutes.

In 1934, Vickers Armstrong produced a mock-up and proceeded to develop prototypes of the weapon, which was selected and passed acceptance tests in 1936.[7][8] The weight specification was exceeded, the muzzle velocity not achieved and the mechanical time fuze, No. 206, was still some years from production. The igniferous No. 199 had to be used and its lesser running time limited the effective ceiling. Gun production started the following year.

On 1 January 1938, the British air defences had only 180 anti-aircraft guns larger than 50 mm and most of these were the older 3-inch guns. This number increased to 341 by the September 1938 (Munich Crisis), to 540 in September 1939 (declaration of war), and to 1,140 during the Battle of Britain. Production continued until 1945, averaging 228 guns per month throughout the period. Guns were also manufactured in Australia.


It fits British, Australian, Polish, United States and Canadian WW2 armies and can be used in bolt action and flames of war.
