What is mk 103?

The MK 103 was a 30mm aircraft cannon developed by the Germans during World War II. It was used primarily on Luftwaffe fighter and bomber aircraft such as the Focke-Wulf Fw 190 and the Messerschmitt Bf 109.

The cannon had a high rate of fire, with a cyclic rate of up to 600 rounds per minute. It also had a relatively high muzzle velocity, allowing it to deliver a powerful punch against both ground targets and enemy aircraft.

The MK 103 was often paired with the MG 151/20, which was a 20mm cannon, to provide a well-rounded armament package for aircraft.

Overall, the MK 103 was a formidable weapon that proved to be very effective in combat situations, especially against enemy aircraft and armored ground targets.
