6993rd Security Group

• Origins: The 6993rd Security Group was originally activated as the 6993rd Security Squadron in 1963 and later elevated to Group status in 1974, under the United States Air Force Security Service (USAFSS). • Primary Mission: The group's main objective was airborne signals intelligence (SIGINT) collection, primarily focusing on intercepting enemy communications during the Vietnam War. • Operation Location: The unit was based at Tan Son Nhut Air Base, South Vietnam, and operated from other locations such as Da Nang and Ubon, Thailand. • Aircraft Used: The 6993rd primarily flew aboard EC-47 "Electric Goon" aircraft, modified versions of the C-47, equipped with electronic surveillance equipment. • Dangerous Missions: Aircrews frequently flew unarmed and slow-moving EC-47s into hostile territory, making them vulnerable to anti-aircraft fire and enemy fighters. • Valor and Sacrifice: The group suffered casualties, including the loss of aircraft and crew members, such as the tragic loss of EC-47 "Baron 52" in February 1973, one of the last US aircraft shot down in Southeast Asia. • Notable Operations: The intelligence collected by the 6993rd played a crucial role in supporting ground operations, providing real-time direction finding and targeting information to US and allied forces. • Recognition: The unit and its members received numerous commendations, including Air Medals and Distinguished Flying Crosses, for their bravery and effectiveness. • Nickname: The group was informally known as "The Silent Warriors" due to the secretive and sensitive nature of their electronic intelligence missions. • Legacy: After the Vietnam War, the group was inactivated in 1974, but its legacy endures in the Air Force’s current airborne reconnaissance and SIGINT missions, with alumni maintaining active veteran associations and reunions.
