Williams Research began developing small gas turbine engines in the 1950s. Its first turbofan, the WR19 (F107 US military designation), was developed in the early-1960s. The uprated F107-WR-103 began in 1980, with a contract for full-scale development received in March 1982, and later redesignated the F112-WR-100.

These engines were designed to propel long-range missiles, for either decoy or attack purposes. In April 1983, the Convair Division of General Dynamics was selected to develop and manufacture the AGM-129A Advanced Cruise Missile (ACM), powered by the F112-WR-100 engine, to arm Boeing B-52H and Northrop B-1B bombers. The ACM was the successor to the AGM-86B air-launched cruise missile, which used the F107-WR-101. The AGM-129A had improved range, accuracy, survivability, and targeting flexibility as compared with the AGM-86B. It also embodied low-observability (stealth) technology. The first production F112 engine was delivered in 1986, and delivery of production AGM-129A missiles began in June 1990.
