The 537th Airlift Squadron (537 AS) is stationed at Elmendorf Air Force Base, Alaska. It was re-activated on Joint Base Elmendorf-Richardson (JBER) in April of 2011. It had been more than 40 years since its deactivation in the early 1970s at Phu Cat Air Base, South Vietnam. At that time, it was the 537th Tactical Airlift Squadron and they flew the C-7 Caribou. The 537th AS shares 12 C-130's with the 144th AS, and works side-by-side to support JBER.
