This year, Nexter, a company of KNDS, will deliver the 300th gun for the Rafale fighter jet.
The M791 cannon, manufactured at Nexter's Bourges site, is the latest in a long line of 30mm DEFA guns dating back to the post-war period. The capabilities of this single-tube gun are unrivalled to date. Thanks to numerous innovations, its rate of fire is the highest in the world: 2,500 rounds/minute. It fires 42 shells in one second, equivalent to 1.5kg of explosive. This performance enables a single M791 gun to be as effective as the Mirage 2000's two M550 guns, which each fire 1,200 rounds/minute. Designed for on-board use, the gun is gas-operated to limit the need for electricity on the aircraft.
