F107 / WR19
An F107 engine on display at the San Diego Air & Space Museum
Type Turbofan
National origin United States
Manufacturer Williams International
First run 1970s
Major applications AGM-86 ALCM
BGM-109 Tomahawk
AGM-158B
Developed into Williams F112

The Williams F107 (company designation WR19) is a small turbofan engine made by Williams International. The F107 was designed to propel cruise missiles. It has been used as the powerplant for the AGM-86 ALCM, and BGM-109 Tomahawk, as well as the experimental Kaman KSA-100 SAVER and Williams X-Jet flying platform.

F122

Williams F122
Type Turbofan
National origin United States
Manufacturer Williams International
Major applications KEPD 350
Number built 699 (as of August 2014)
Developed from Williams F107
Variants Williams F415

The Williams International F122 is a twin-shaft, axial-centrifugal-flow turbofan that is similar to the F107 in configuration but has a maximum thrust of 900 lbf (3.33 to 4.0 kN).

Design and development

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.
