Three heavily modified C-130E replaced the C-97G of the 7405th Operations Squadron (as 7405th Support
Squadron was renamed on 1st January 1973). As with their predecessors,
these aircraft carried a variety of sensors with advanced
capabilities. If one sensor detected a new and unusual activity,
the aircrew could almost instantly use the other sensors to see
what the new activity was about.
When 62-1819 was photographed on landing at Tempelhof in November 1978,
it was already assigned to the 7405th OS despite its "Military Airlift Command" markings. Although these
false markings could have confused most of the Western observers at the time, they were completely useless
to fool the Soviet intelligence services.
