Turbofan engine for cruise missiles
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.

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.
