MK44 is an upgrade from 25mm M242 Bushmaster to a fearsome 30mm chain gun (30×173mm). Upgrade did not bring just a new caliber and with it more firepower but also new ammunition which can be set to preexplode when in front of the enemy. The gun can destroy almost any light armored vehicle and can also engage in urban environment where the concrete wall is no obstacle. It also uses a very powerful GAU-8 Avenger ammunition, which can be fired 200 times per minute and efficient in ranges up to 3000 meters away depending on the type of the ammunition.
MK44 can be placed on almost any ground vehicle(CV90), gunship(Type 23 frigate) or even aircraft(AC-130 Lockheed) and is remote controlled from the weapon stating
which can be placed inside any vehicle.
