The present invention relates to a method and an apparatus for imparting, in a continuous and unbroken sequence, to such warheads (3) as, housed in a protective canister (2) are ejected out into ballistic ejection trajectories, a predetermined rotational movement in connection with the warhead (3) being ejected out of the canister (2). According to die invention, this object is attained in that the canister (2) is spun up to the desired speed of rotation by adapted gas outlet nozzles (27-30) discharging in the outer periphery of the canister (2), these nozzles being fed with combustion gases from a central combustion chamber (15) in which a propellant charge (21) is combusted and from which powder gases in the final phase of the propellant charge combustion are moreover led off for ejection of the warhead (3) from the canister (2).
