Naval Support Force Antarctica

The Naval Support Force Antarctica (NSFA) was a United States Navy unit established in 1955 to provide logistical, operational, and construction support for Operation Deep Freeze, the U.S. mission in Antarctica. Headquartered at McMurdo Station, the NSFA managed sea and air logistics, constructed and maintained research facilities, and supported scientific expeditions across the continent. The unit played a crucial role in maintaining year-round access to Antarctica, enabling critical scientific research during the Cold War and beyond. The NSFA was deactivated in 1998, with its duties transferred to civilian agencies under the National Science Foundation.
