The DEFA cannon (Direction des Études et Fabrications d'Armement) is a family of widely used French-made aircraft revolver cannons firing the standard 30 mm caliber NATO rounds.

 The DEFA 553 is a gas-operated five-chamber revolver cannon using pyrotechnic cocking and electrical ignition. It fires a range of 30 mm ammunition in various types, and is capable of continuous fire or of 0.5-second or 1-second bursts.

The 553 was superseded by the DEFA 554, which incorporates a number of detail improvements. The DEFA 554 uses three, rather than two, of the chambers for reloading, increasing rate of fire. Barrel life and mechanical reliability are improved, and an electrical control unit now allows the pilot to select two rates of fire: 1,800 rounds per minute for air-to-air use or 1,200 rounds per minute for air-to-ground attacks. The 554 also provides three pyrotechnic cartridges rather than one, allowing the pilot to cock the weapon only after take-off while still having two cartridges to recock in flight.
