Precast concrete foundations are loaded onto the Military Sealift Command chartered ship MV Ocean Gladiator as part of the Operation Deep Freeze 2024 cargo loadout. Cargo operations are being coordinated by MSC's Expeditionary Port Unit 114 in Port Hueneme Calif. Operation Deep Freeze is a joint service, on-going Defense Support to Civilian Authorities activity in support of the National Science Foundation (NSF), lead agency for the United States Antarctic Program. Mission support consists of active duty, Guard and Reserve personnel from the U.S. Air Force, Navy, Army, and Coast Guard as well as Department of Defense civilians and attached non-DOD civilians. ODF operates from two primary locations situated at Christchurch, New Zealand and McMurdo Station, Antarctica. An MSC-chartered cargo ship and tanker have made the challenging voyage to Antarctica every year since the station and its resupply mission were established in 1955.
