ABSTRACT:
A rocket boosted and/or sustained round for launching from a firearm, recoilless rifle, mortar or any other type of closed breech launcher and an adjustable, recoiling tripod support for the firearm or other type of closed breech launcher. The tripod supports the launcher during launch of the rocket boosted and/or sustained round. The rocket boosted round, which may be launced, for example, from the conventional M-16 rifle, is aerogyro stabilized and is provided with a tubular tailpipe that slidingly fits over the end of the firearm barrel. A rocket motor which is ignited during or after launch is coupled to the tailpipe and a warhead having a predetermined ogive configuration is coupled to the rocket motor. An ignition delay means in the round such as a pyrotechnic delay may be provided to allow a predetermined time delay between launch of the round and the ignition of the rocket motor. Other round configurations incorporate a progressive burning rocket motor grain instead of a pyrotechnic delay. The low thrust and negligible back blast from the initial burn of the rocket allows the elimination of the time delay from launch to rocket motor ignition. The round is launched by firing a grenade launcher cartridge in the launcher. The hot, gaseous products of combustion from the cartridge enter the tailpipe of the round and launch the round from the launcher. The ignition delay means if utilized, initiates ignition of the rocket motor after a predetermined time interval has elapsed from launch.
