ABSTRACT:
An improved launch cartridge means for launching a rocket powered round from a spike type launcher wherein the launch cartridge is provided with a probe means extending through the nozzle of the rocket powered round during a first portion of the launch phase thereof to reduce the pressure of the launch gases on the rocket propellant grain of the rocket powered round. The probe means is detachably coupled to the launch cartridge by selectively removable coupling means. For the condition where a pure ballistic trajectory of the rocket powered round is desired, that is, without ignition of the rocket propellant grain in the round, the coupling means is removed and the probe portion of the launch cartridge is driven into gas sealing engagement with the nozzle passage way of the rocket powered round to prevent the launch gases from igniting the rocket propellant grain. If rocket powered flight is desired the coupling means is left installed and the launch gases both launch the round and ignite the rocket propellant grain. The reaction of the launch cartridge to the launch forces exerted by the launch gases positions the launch cartridge adjacent the end of the spike launcher when the rocket propellant round has been launched.
