A pyrotechnic device for launching at least one projectile includes, in a longitudinal launcher tube closed at the rear by a rear wall, a closure member expelled when subjected to a longitudinal force exceeding a predetermined threshold and retaining at least one projectile on opposite sides of which are a front chamber and a rear chamber in which an impulse cartridge builds up a gas pressure simultaneously. In this way a plurality of projectiles can be fired sequentially by means of a single impulse cartridge.
