About this Unit
McMurdo Station, established in 1955 by the United States Navy as part of Operation Deep Freeze, serves as the primary logistical hub for American operations in Antarctica. Initially constructed to support scientific research and maintain a strategic presence during the Cold War, the station was operated by the U.S. Navy until 1998, when responsibilities shifted to civilian contractors under the National Science Foundation. Over the decades, McMurdo Station has played a critical role in supporting international scientific collaboration and logistical operations across the continent. Although no longer a traditional military unit, its origins and operations remain deeply rooted in U.S. military history and polar exploration.

First Nuclear Power Plant in Antarctica: In 1962, the U.S. Navy installed the PM-3A nuclear power plant at McMurdo, providing electricity until 1972, making it the only nuclear-powered station on the continent.
•
Military Airlift Operations: The U.S. Air Force and Navy have operated LC-130 Hercules ski-equipped aircraft, providing vital supply missions and medical evacuations known as "Operation Deep Freeze Airlift."
•
The Ross Island Firehouse: The station operates the southernmost fire department in the world, initially staffed and managed by military personnel.
•
Historic Rescue Missions: In 1961, the Navy evacuated a Soviet scientist requiring surgery, marking one of the first international rescue collaborations in Antarctica.
•
Antarctica’s First ATM: The military-supported logistics at McMurdo enabled the installation of the world’s southernmost ATM in the station’s post office in 1998.
•
Transition to Civilian Control: In 1998, the U.S. military officially handed over daily operations of McMurdo to civilian contractors, though military units still provide essential logistics and emergency support.
