operate from an aircraft carrier (the
USS Ranger) in February 1964 and deploying to Takhli Air Base in Thailand
for surveillance of North Vietnam during the following March. Always a sensor "bus," such aircraft could and did
carry SIGINT equipment during their
missions, with noted U-2 researcher

A major change between 1964 and 2014 has
been the proliferation of countries able to field an
airborne SIGINT capability. To those players already
mentioned, we can add nations as diverse as
Colombia, Israel, Italy, Greece, Japan,
Saudi Arabia and Turkey.

China until March 1964 when penetration flights were re-started following
the loss of an RB-69 over China during
the previous year. Such flights were
again suspended in June 1964 when another aircraft was shot-down and the
surviving aircraft (plus a replacement
that was fielded during 1965) continued

to fly stand-off missions until circa late
1966.
First flown in April 1962, and declared operational during November
1965, the Mach 3 A-12 Oxcart reconnaissance aircraft is known to have been
equipped with an ELINT capability
alongside its high-resolution cameras,
with the former believed to have gone
on to be used operationally during the
type's Black Shield missions over Cambodia, North Korea, Laos and North
Vietnam during the period December
1967 to May 1968. Again, released documentation suggests that the Oxcart's
ELINT system had a swath of 490 nmi
to port and starboard when it was being flown at operational attitude. Last
but not least, 1964 saw the last of the
CIA's first generation U-2s (examples
of which were also being flown by the
USAF) demonstrating their ability to

Chris Pocock identifying the so-called
Systems 1, 3, 6 and 192 as being U-2
SIGINT payloads of the period. Of these,
the Ramo-Wooldridge System 1 is described as having been a pre-set 2- to
4-GHz or 8- to 12.5-GHz band crystal
video ELINT package that was in USAF
use up until the late 1960s, while the
Ramo-Wooldridge System 3 is billed as
being a VHF-band COMINT capability
that was used by both the CIA and the
USAF from 1956 to the mid 1960s. For
its part, the Ramo-Wooldridge System
6 is reported to have been in service
aboard CIA aircraft until the late 1960s
and is understood to have covered the
30-MHz to 26.5-GHz frequency band.
Last but not least, Pocock describes
System 192 as having been an experimental ELINT system with directionfinding provision that was trialed by
the USAF during 1963-1964.
