Developed in the mid-1950s for the U.S. Army, HAWK uses a two-level-thrust motor incorporating a dual-chamber design. Gas from the sustain phase burn exhausts out a tube running through the boost-phase chamber.  Both phases exhaust out nozzle extension tubes that bypass the guidance equipment installed at the aft end of the missile. The TX-59, used for early HAWK development flights, is believed to be the first dual-chamber-design motor.
