SIG IN T
and to have lost 13 of its aircraft to the
enemy. It is perhaps ironic that the RAF
preferred the B-17 as a countermeasures
aircraft (even beginning conversion of
a second squadron to the type during
April 1945) to the B-24 which, in turn,
was the US Army Air Force's jamming
platform-of-choice. As the song says,
"you like tomato and I like tomahto ...".
Whatever the merits of these two
iconic American aircraft, the RAF's
jamming Fortresses contributed much
to the service's RCM campaign against
Germany's night-fighter defenses and
paid a heavy price in the process. That
such was the case is perhaps not surprising when the reader considers that

an SWF force of perhaps 20 aircraft
could, and did, attract large numbers of
enemy fighters or that, at one point in
the type's career, the Command's B-17
crews were required to orbit some of
the most heavily defended targets in
the world for long periods of time in order to protect the ingress and egress of
their "big friends," the bombers. As a
final thought (and bearing in mind the
close watch the USAAF kept on the British RCM campaign), it seems likely that
214 Squadron's pioneering work at least
informed America's decision to introduce escort jamming B-29s in support of
its strategic air offensive against Japan
during the summer of 1945. a

Window dispensing, the Piperack 63- to
93-MHz AI jammer, and (in some cases)
the Carpet GL/GCI radar jammer. Again,
the RAF's B-17 jammers were also used
as part of the Special Window Force (SWF)
in addition to their escort activities. As
such, SWF operations took the form of
electronic "spoofs" that mimicked real
attacks and were designed to confuse
and disorientate the enemy's fighter
controllers. Elsewhere, 214 Squadron's
"Forts" also took part in the Big Ben
campaign against German V-2 ballistic
missile sites.
During the period of April 20-21, 1944
to May 2/3, 1944, 214 Squadron is reported to have dispatched 1,390 RCM sorties
