The 20th Special Operations Squadron reactivated in 1976 at Hurlburt Field, the unit mission remaining unconventional warfare and special operations using UH-1N gunships and CH-3Es. The HH-53H Pave Low replaced the CH-3E in 1980, providing a long range, heavier lift helicopter capability. "The Air Force's newly operational fleet of nine HH-53H Pave Low CSAR helicopters was abruptly transferred to the special operations forces in response to the failed Iranian hostage rescue attempt and the lack of dedicated long-range vertical lift platforms." "The helicopters brought 200 new military jobs to Hurlburt, bringing the number of military positions at the base to 3,200."
