The Hispano-Suiza HSS 831A is a variant of Hispano-Suiza HSS 831 which was a popular anti-aircraft gun around the 1950s. The HSS 831A was combined with a Oeil-noir fire control system and an armored turret to create the S 401 A. First installed on the chassis of the [[AMX-13 (Family)|AMX-13]] light tank, this design for low altitude air defense was soon changed with the mounted on the larger [[AMX-30 (Family)|AMX-30]] to create the [[AMX-30 DCA]] which offered superior mobility, double the ammunition storage, and a more stable firing platform. A fair weather weapon, the guns had a rate of fire of 650 rounds per minute and fires in either 5 or 15-round bursts. This vehicle was not picked by the French, but instead ordered by Saudi-Arabia. The HSS 831 has been known as the Oerlikon KCB, serving as a scaled up variant of the [[Oerlikon KAD (20 mm)|Oerlikon KAD]], after the Oerlikon bought out the Hispano-Suiza arms division.
