Antarctic Support Activities 1968-69

Antarctic Support Activities (ASA) was a U.S. Navy unit tasked with logistical and operational support for scientific missions in Antarctica during Operation Deep Freeze. In the 1968-69 season, ASA played a critical role in maintaining supply lines, constructing and servicing bases such as McMurdo Station, and ensuring safe air and sea transport for personnel and equipment. The unit operated in extremely challenging conditions, coordinating with civilian scientists and other military branches to enable vital research on the continent. Their efforts during this period contributed significantly to the advancement of polar science and reinforced American presence in Antarctica.
