Williams International F107-WR-101 Turbofan By The F107-WR-101 is an advanced, two-shaft turbofan engine that powers the USAF AGM-86B Air Launched Cruise Missile. The engine's design emphasizes light weight and compact size because of the limited space in the ALCM. The F107-WR-101 uses a special high-density aviation turbine fuel that has more energy for a given volume than standard fuels. The fuel is blended to endure harsh weather conditions and long storage periods. This engine was acquired by the museum in March 1983.
