6950 Security Service

The 6950th Security Squadron, later known as the 6950th Security Group and then the 6950th Electronic Security Group, was a United States Air Force unit established in the 1960s. Based at RAF Chicksands in the United Kingdom, the unit played a key role in signals intelligence (SIGINT) operations during the Cold War, monitoring and analyzing communications related to Soviet and Warsaw Pact activities. The 6950th operated the iconic "Elephant Cage" AN/FLR-9 antenna array, collecting vital intelligence for U.S. and NATO commanders. The unit was inactivated in the mid-1990s as the U.S. Air Force reorganized its intelligence operations following the end of the Cold War.
