The '''Bordkanone BK 37''' (''(on-)board cannon 37'') was a 37mm anti-tank/bomber [[autocannon]] based on the earlier 37 mm [[3.7 cm FlaK 43|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 87]]D-3 and G-2, [[Henschel Hs 129]]B-2/R3, [[Messerschmitt Bf 110]]G-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 [[Shell (projectile)|shells]] in 37x263B mm [[caliber]] at 160 rounds per minute.
