The Oerlikon KBA is a 25 mm (25×137mm) autocannon, developed as a close range multipurpose weapon for the mechanised battlefield, originally made by Oerlikon (now Rheinmetall AG) and currently produced in Rheinmetall Italia S.p.A. facilities. It is a positively locked breech, gas and recoil operated cannon with a rotating bolt head and a dual-belt selective feed system taking a 25mm NATO cartridge. The rate of fire in burst mode is 600 rounds per minute but it can be adjusted electronically and reduced to single shot or a selectable range from 100 up to 200 rounds per minute.[1]
Due to its firepower, its range of ammunition and its "Instant Ammunition Selection Device" (IASD), which allows the gunner to easily switch between armor-piercing and high-explosive rounds, the KBA cannon can engage lightly armoured vehicles, infantry, anti-tank positions, helicopters, combat aircraft and ships.
