Abstract
A projectile includes a pyrotechnical detonation chain arranged to be ignited in response to a launching of the projectile. The chain includes two successive spaced-apart portions that are spaced apart to prevent ignition from being transferred therebetween. One of the portions is movable into contact with the other. A holder imposes a yieldable retaining force (e.g., friction, or shear pin) against the movable portion. That force can be overcome by momentum of the movable portion when the projectile strikes a target, whereupon the movable portion moves into contact with, and ignites, the other portion.
