AKA: AM.10;BQM-111;Firebrand;Model 258;ZBQM-111A;SLAT. Thrust: 2,300.00 kN (517,000 lbf). Gross mass: 2,270 kg (5,000 lb). Height: 10.37 m (34.02 ft). Diameter: 0.71 m (2.32 ft). Span: 2.74 m (8.98 ft).
SLAT (Supersonic Low Altitude Target), a derviative of ASALM-PTV was, in fact built and tested several times. The ramjet built by Marquardt (with a solid propellant grain and motor case by Thiokol) did not actually work as planned and had pre-ignition problems, possibly due to inlet duct acoustics and also failures to ignite due to the missiles' battery problems. Missile stability/control problems developed during 3-4 test flights which used air drops from F-4's flying at the missile range off Point Mugu. The missile was supposed to fly supersonic 6 m above the ocean and replace Vandal targets that the Navy was running out (Vandal used surplus navy Talos ramjet surface-to-air missiles boosted by solid motor. The missiles were originally built by Bendix and developed by the Johns Hopkins Applied Physics Laboratory). The program ended before the technical problems could be corrected around 1988-89. In 2003-04 the Navy developed and flew a variable-flow ducted rocket powered missile for the target mission (essentially another solid fuel ramjet). This was originally developed for an advanced version of AMRAAM. The propulsion was from ARC (later absorbed by Aerojet) and the airframe and systems by Orbital Sciences.
