After the cancellation of the BQM-90 program in 1973, the Navy had to look for other target missiles to simulate attacking anti-ship missiles. In 1975, it was decided to convert some obsolete RIM-8 Talos missiles to MQM-8G Vandal targets as a short-term solution to simulate the terminal phase of a missile attack. In parallel, the ZBQM-111A program was defined to develop a completely new target vehicle which was to be able to replicate all phases of an anti-ship missile's mission profile. In May 1977, Teledyne Ryan was awarded the ZBQM-111A development contract for their Model 258 Firebrand target.

The Firebrand was designed as a parachute-recoverable ramjet-powered target suitable for ground and air launch. Solid-propellant rocket boosters propelled the BQM-111 to ramjet ignition speed of Mach 1.2. After an air launch from a DC-130, the Firebrand could cruise at Mach 2.0 at 12200 m (40000 ft) before diving to 90 m (300 ft) for the final run towards the "attacked" ship. The target was guided by a pre-programmed radio command guidance system with options for manual override. Any uncommanded deviation from the pre-planned mission profile would lead to immediate start of the recovery sequence to avoid endangering ships by an uncontrolled high-speed vehicle.
It was originally planned to build nine Firebrand test vehicles, and to begin flight tests in 1983. However, the ZBQM-111A program ran into funding difficulties. It also didn't help that the Firebrand design with its two ramjets and boosters came out as a heavy vehicle, possibly only marginally suitable for launch from the surface or from C-130 aircraft. The program was finally cancelled in January 1982. The Navy decided to continue the use of the MQM-8 Vandal instead, and to formulate a new requirement for a dedicated anti-ship missile target. The latter eventually resulted in the AQM-127 SLAT (Supersonic Low-Altitude Target) program.
