unit was manufactured by the Granger Company. One of these de
vices was aboard Gary Powers' U-2 when he was shot down.
System-X was a modification of the HRB's System-VII that was
specially built in 1962 for a mission over the Soviet Union that never
took place. Systems-XI through XV were ECM devices used by U-2s
overflying China and North Vietnam during the Vietnam war.
System-XVI was a passive ELINT collector.
System-XVII was built by HRB-Singer as a result of an October
l 963 USIB requirement for the collection of antiballistic-missile
(ABM) data from Saryshagan. The system was to be deployed in a
U-2 that would fly over western China, along the Sino-Soviet border,
collecting data on the ABMs being tested at Saryshagan. By the time
the unit was completed in l 965, however, the tipoff time before test
launches had been reduced from almost 24 hours to less than an hour,
making it impossible to stage U-2 missions in time to collect the data.
In the late l 960s, additional ECM systems were needed to coun
ter the increasing threats posed by more accurate SAMs and higher
flying aircraft. System-XX was specifically designed to counter the
acquisition and guidance radars used by MIG aircraft, and
System-XXII was an infrared jammer to counter air-to-air missiles.
System-XXI, a COMINT package that replaced the much older
System-III, was originally developed for the OXCART program and
was later adapted for use aboard the follow-on U-2, the U-2R.
