Priming device initiated electrically for a projectile

A priming device for a projectile comprising:

• a body;
• a safety and arming device;
• and
• a first electrically initiated detonator that is activated by an electronic firing module, wherein
• the priming device incorporates a second detonator integral with a rotor or flap of the safety and arming device,
• the second detonator is activated by a firing pin,
• the firing pin is arranged in a fixed position relative to the body and arranged opposite the first detonator of the priming device,
• the firing pin is integral with a spacer plate fixed with respect to the body of the projectile, the spacer plate incorporating an embrittlement groove surrounding the firing pin, and
• the firing pin is configured to be detached from the fixed position by shearing of the spacer plate through a thickness of the spacer plate within the embrittlement groove upon ignition of the first detonator and to be projected by the gases resulting from the ignition of the first detonator.
