“Operation Deep Freeze” has come to be used as a general term for US operations in that continent, and for the regular missions to resupply US Antarctic bases, coordinated by the United States military. For a few decades the missions were led by the United States Navy, though the Air National Guard and National Science Foundation are also important parts of the missions.
The last US Navy LC-130 left Antarctica to end naval support DEEP FREEZE. Operational support switched in 1998 to the New York ANG’s 109th Airlift Wing.
