DEFA 552a, 553 & 554

The 30mm DEFA is a single barrel, gas operated revolver cannon chambered for electrically primed, 30mm x 113mm ammunition. The 552a and 553 Cannon share many common components and offer similar performance. However, the 553 cannon is fitted with a two shot cartridge-initiated re cocking system and an improved chrome plated barrel. The 554 cannon is similar in design, but with the following exceptions;

  • Rate of fire was increased by feeding ammunition in two stages instead of three and can be controlled for 1,200 or 1,800spm.
  • The number of re-cocking cartridges was increased to seven.
  • Many of the components are of new design and cannot be interchanged.ApplicationsThe DEFA is a lightweight, compact weapon suitable for all types of combat or trainer aircraft.

Mounting of the gun is possible at any angle through 360° on the longitudinal axis. Both left and right hand feed versions are available. It is suitable for installation internally, or externally.
