The Williams International F122 is an American turbofan engine developed by Williams International.

Design and development

The F122 is a twin-shaft, axial-centrifugal-flow turbofan that is similar to the F107 in configuration but has a maximum thrust of 900 pounds per thrust (3.33 to 4.0 kN). The F122 is used to power the KEPD 350 air-launched cruise missile, and was the powerplant for the cancelled AGM-137 TSSAM air-launched cruise missile.[2] Although the AGM-137 was cancelled, the F122 was first used for the Taurus KEPD when it was flown aboard that missile in April 2002.[3]
