The mk103/38 was a late-war, four-gun installation of the mk103 3cm gun from rheinmetall borsig. The mk103 was an electrically fired, recoil and gas-operated automatic cannon designed to be used as a dual-purpose weapon against air and ground targets

The mk103 had a rate of fire of 280 rounds per minute using high explosive (he) rounds, and 420 rounds per minute when firing armor piercing rounds

The experimental mk103/38 four-gun installation proved troublesome due to fact that the mount was originally designed for the smaller 2cm flak 38, and heavy vibration took it s toll on both the equipment and the crew aiming the weapon
