Abstract
A projectile to be fired from a tubular or rail-shaped launcher has a warhead integral with a rearwardly extending tube of smaller diameter which contains a propulsive charge inserted between the warhead and a sabot carrying a frangible inertial mass. The rear end of the tube has a constricted opening which, upon detonation of the charge, retains the rearwardly moving sabot while giving passage to the disintegrating mass as the projectile is propelled forwardly. The propulsion gases evolving within the tube are temporarily retained by one or more heat-destructible plugs in the sabot and/or in the tube which melt, burn or char to allow the delayed escape of the gases whereby an in-flight thrust is imparted to the projectile.
