About this Unit
The 6922nd Security Squadron was a United States Air Force unit stationed at Clark Air Base in the Philippines. Activated during the Cold War, its primary mission focused on signals intelligence (SIGINT) and electronic surveillance, supporting U.S. and allied operations in the Asia-Pacific region. The squadron played a critical role in monitoring regional communications and gathering intelligence during conflicts such as the Vietnam War. The unit remained active until the early 1990s, when the eruption of Mount Pinatubo and subsequent U.S. withdrawal from the Philippines led to the closure of Clark Air Base and the squadron’s inactivation.
