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 Flak 8.8 cm 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.
The 3-inch 20 cwt with its powerful and stable in flight, [18] 16 lb (7.3 kg) shell and fairly high altitude was well suited to defending the United Kingdom against high-altitude Zeppelins and bombers. The 16-pound shell took 9.2 seconds to reach 5,000 ft (1,500 m) at 25 degrees from horizontal, 13.7 seconds to reach 10,000 ft (3,000 m) at 40 ...
3.7 cm Flak 18/36/37. The 3.7 cm Flak 18/36/37 was a series of anti-aircraft guns produced by Nazi Germany that saw widespread service in the Second World War. The cannon was fully automatic and effective against aircraft flying at altitudes up to 4,200 m. [4] The cannon was produced in both towed and self-propelled versions.
Hiram Maxim originally designed the Pom-Pom in the late 1880s as an enlarged version of the Maxim machine gun.Its longer range necessitated exploding projectiles to judge range, which in turn dictated a shell weight of at least 400 grams (0.88 lb), as that was the lightest exploding shell allowed under the Saint Petersburg Declaration of 1868 and reaffirmed in the Hague Convention of 1899.
Effective firing range. 2,000 m (6,600 ft) (effective ceiling) Maximum firing range. 8,500 m (9,300 yd) at 37.5°. The 3.7 cm SK C/30[Note 1] was the German Kriegsmarine 's primary 3.7 cm (1.5 in) anti-aircraft gun during the Second World War.

Design of a horse-drawn, 3.7 cm anti-tank gun (designated 3.7 cm Pak L/45) by Rheinmetall commenced in 1924 and the first guns were issued in 1928. [5] By the early 1930s, it was apparent that horse-drawn artillery was obsolescent, and the gun was modified for motorized transport by substituting magnesium-alloy wheels and pneumatic tires for the original spoked wooden wheels, allowing it to be ...
The Ordnance QF 95-mm infantry howitzer was a version built as a conventional towed artillery piece. Perhaps in response to the success of the German sIG 33, a proposal was circulated in the summer of 1942 by the British Army for an infantry howitzer for direct fire against concrete structures, like pillboxes.
