3613th Combat Crew Training Squadron (water survival school)

The 3613th Combat Crew Training Squadron was a United States Air Force unit established to provide specialized water survival training to aircrew members. Activated during the Cold War, the squadron operated primarily out of Homestead Air Force Base, Florida, and later at Tyndall Air Force Base. Its mission was to ensure that pilots and other aircrew were prepared to survive and evade capture in the event of a water landing or bailout. The unit was eventually redesignated as the 17th Crew Training Squadron in the 1990s as part of a broader reorganization of Air Force training programs.
