This is the squadron patch for the 339th Flight Test Squadron (FTS) based at Robins AFB, GA. It is part of the Warner Robins Air Logistics Center, with a mission to certify aircraft as worthy to return to service. The squadron is responsible for conducting flight tests on the Lockheed C-130 Hercules, the Lockheed C-5 Galaxy and McDonnell Douglas F-15 Eagle after program depot maintenance is completed. Along with their flight test responsibilities, the squadron also picks up and delivers aircraft including battle damaged aircraft to locations where they are needed or can be repaired. During World War II, the squadron was given the assignment to shoot down the plane carrying Imperial Japanese Navy Admiral Isoroku Yamamoto in Operation Vengeance. This patch does not come with velcro.
