Abstract: An arrangement for firing a projectile from a recoilless weapon with a firing barrel open at both of its ends, by means of a propellant charge tamped toward the rear with an inert, pulverulent compensating mass, reduces the noise and the shock waves of the firing. The projectile and the compensating mass are adapted to each other with respect to their mass and the distances to be traversed by each within the firing barrel so that the compensating mass fully vacates the firing barrel only after the projectile vacates the firing barrel.

Abstract: Minimum probability of collision during the dispensing procedure is desirable in the distribution of submunition, such as mines, bomblets, or subsidiary projectiles by means of rockets or shells.For this purpose, a dual ejection process is provided wherein the individual submunitions are accommodated severally in special dispensing units which units, in turn, are inserted as secondary elements in the rockets or shells. Upon primary ejection over the target area, the dispensing units are ejected, stabilized at a distance from the rockets or shells, and subjected to a deceleration different from that of the rockets or shells so that the flight paths diverge, thus precluding collision. Subsequently, in a secondary ejection, the submunition is ejected from the dispensing units.
