The cannon is a larger and more modern version of the 35 mm Bushmaster III chain gun, which itself is a larger version of the 25 mm M242 Bushmaster cannon. Although its shells, 50 x 228 mm, are twice the diameter of the 25×137mm cartridge of the M242, the 50mm cannon is not much longer than the smaller weapon. [ 2 ]

Despite superficially appearing to be inferior based on a simple comparison of round diameters, when firing conventional ammunition the smaller, 4.5 inch Mark 8 naval gun is comparable to the standard 155 mm (6.1 in) gun-howitzer of the British Army.
