BK 37

BK 37

The Bordkanone BK 37 ("(on-)board cannon 37") was a 37mm anti-tank/bomber autocannon based on the earlier 37 mm Flak 18 made by Rheinmetall. It was mounted on World War II Luftwaffe aircraft such as the anti-tank or bomber-destroyer versions of the Junkers Ju 87D-3 and G-2, Henschel Hs 129B-2/R3, Messerschmitt Bf 110G-2/R1-3, and others. The cannon could be attached under the wings or fuselage of the aircraft as a self-contained pod with a 12-round magazine. It fired APCR (Tungsten hard core) ammunition or high explosive shells in 37x263B mm caliber at 160 rounds per minute.
