Telemetry Intelligence (TELINT) During the Cold War

Trnasportable Ground-Based Collection
Transportable Ground-Based
Telemetry Collection (LEFTOUT)
During the Cold War, the land-based AN/
MSQ-90V telemetry collection system was available
for air transport to locations around the Pacific
Ocean. It was operated and maintained by the U.S.
Army Security Agency (USASA) during the 1970s
and early 1980s. Other smaller, limited-capability,
transportable telemetry collection equipment systems
were also used during the Cold War for special
collection opportunities. The system project name
was LEFTOUT, and the system was developed by
E-Systems in Greenville, Texas, now part of L-3
Communications Holdings.
