The Oerlikon Contraves KBA 25 mm cannon is a fully automatic, positively locked, gas-operated weapon with a rotating bolt head and double belt feed. These features guarantee high reliability and safety, even under the most extreme environmental conditions.

The KBA offers a wide range of firing modes: single shot; programmable rapid single shot with a rate of fire of up to 175 rds/min; and full automatic fire of 600 rds/ min. The cannon functions, such as cocking and firing, are electrically actuated by remote control from the gunner's control box and in auxiliary mode mechanically by a hand crank and a trigger pedal.
