USAFSS Misawa, Japan

• Birth of USAFSS at Misawa: The United States Air Force Security Service (USAFSS) established its presence at Misawa Air Base, Japan, in the early 1950s, making it one of the first and most critical overseas USAFSS locations during the Cold War. • Role in Signals Intelligence: The USAFSS at Misawa was a major hub for signals intelligence (SIGINT) operations, intercepting and analyzing Soviet and Chinese military communications across the Far East. • The "Elephant Cage": The base housed a massive AN/FLR-9 Circularly Disposed Antenna Array (CDAA), nicknamed the "Elephant Cage," which was visible for miles and served as a key listening post. • 24-Hour Operations: USAFSS squadrons at Misawa ran continuous 24/7 operations, with rotating shifts of linguists, analysts, and radio operators to ensure constant surveillance during the height of the Cold War. • Intercepting MiG Communications: Misawa-based units played a significant role in monitoring and decoding North Korean, Chinese, and Soviet aircraft radio traffic, providing valuable intelligence during regional crises. • Secret Squirrel Missions: Many USAFSS operations at Misawa were highly classified, with airmen often referring to themselves as "Secret Squirrels" due to the sensitive nature of their work. • Support for Vietnam War: Personnel and intelligence from Misawa directly supported operations during the Vietnam War, including the infamous Gulf of Tonkin incident. • Cold War Close Calls: There are stories of USAFSS operators at Misawa detecting unusual activity or communications that helped avert potential conflicts or provided early warning of hostile intentions. • Integration with Allied Forces: The USAFSS at Misawa worked closely with Japanese and other allied intelligence services, fostering relationships that strengthened regional security. • Legacy and Transition: The USAFSS became the Electronic Security Command in 1979, and its legacy at Misawa continues today through the 373rd Intelligence, Surveillance and Reconnaissance Group, which upholds the tradition of intelligence excellence at the base.
