About this Unit
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.
Historical Facts
•
Establishment: The Naval Support Force Antarctica (NSFA) was established in 1955 to provide logistical support for American scientific research in Antarctica as part of Operation Deep Freeze.
•
Operation Deep Freeze: NSFA was the key naval organization behind Operation Deep Freeze, which enabled the construction and resupply of research stations such as McMurdo Station and the Amundsen–Scott South Pole Station.
•
Seasonal Deployments: NSFA operated primarily during the Antarctic summer, when sea ice permitted ship access and aircraft could land on prepared ice runways.
•
LC-130 Hercules Aircraft: The unit famously operated LC-130 Hercules aircraft, specially equipped with skis to land on snow and ice, delivering vital cargo and personnel.
•
Seabees in Antarctica: U.S. Navy Construction Battalions (Seabees) under NSFA constructed and maintained the research stations, often working in extreme cold and hazardous conditions.
•
Icebreakers: NSFA coordinated U.S. Navy and Coast Guard icebreakers, such as the USS Glacier and USCGC Polar Star, to clear paths for supply ships through thick Antarctic sea ice.
•
Historic Airlift: In the late 1960s, NSFA participated in the first successful airlift of a scientific party to the South Pole since the original Amundsen-Scott expedition.
•
Medical Evacuations: NSFA organized several daring mid-winter medical evacuations using aircraft in near darkness and extreme weather, saving lives at remote outposts.
•
International Cooperation: The unit often worked with allied nations, supporting joint scientific ventures and logistics, reflecting the global nature of Antarctic research.
•
Disestablishment: NSFA was disestablished in 1998, and its responsibilities were transferred to the civilian Antarctic Support Contract, marking the end of U.S. Navy’s direct role in Antarctic logistics.
