Abstract

A round of ammunition comprising a missile (10), retaining means (11) for holding the missile, and a cartridge (12); and the cartridge (12) is an assembly comprising a hollow casing (13) within an intermediate portion of which is a gas storage space (18) disposed between a hollow discharge (front) end portion (14) and a base (rear) end portion (20) of the casing, discharge valve means (30) and actuating means (60). The actuating means generally comprises servo-piston means (61), servo actuating means (62) and discharge valve actuating means (63) arranged so that the means (62) is responsive to being struck by a firing pin (43) of a gun to allow the piston means (61) to utilise energy from compressed gas stored in the space to open the discharge valve means, and thus release the gas to expel the missile (10) from the retaining means. A shock ab­ sorber insert (400) is provided to cushion the end of the valve opening movement of the servo-piston (61).
