Antarctic Support Activities W:O 66-67

**Antarctic Support Activities W/O 66-67** was a specialized U.S. Navy unit tasked with supporting scientific research and operations in Antarctica during the 1966–1967 austral summer. Operating under the broader framework of Operation Deep Freeze, the unit provided vital logistical, transportation, and engineering assistance to the United States Antarctic Program. Personnel facilitated the resupply of remote research stations, managed air and sea operations, and ensured the safety of scientists working in extreme polar conditions. Their efforts contributed significantly to the success of American scientific endeavors on the continent during a pivotal period of Cold War-era exploration and collaboration.
