The cannon of the DEFA 30 M 550 family (F2A/F2B/F3/F4) are specially designed to arm combat aircrafts. They make up an excellent trade-off between weight, volume and firepower.

They fire the international 30mm x 113B standard ammunition, available in a range suitable for the most varied targets covering both air-to-air and air-to-ground combat.

The gas-operated cannon mechanism reduces the electrical power requirements. Its design allows replacing the barrel without disassembling the weapon.

13500 guns are now in service on several types of aircraft (Mirage 2000, AMX, Super-Etendard) in more than 40 countries.
