The U.S. Coast Guard Cutter Polar Star (WAGB 10) sails under San Francisco's Golden Gate Bridge after its 138-day deployment to Antarctica for Operation Deep Freeze 2024, March 31, 2024. The cutter will soon enter a Northern California drydock for phase four of its five-year service life extension program to prepare the cutter for the following year's Operation Deep Freeze, which is the annual logistical support mission provided by the Department of Defense to the National Science Foundation, managed by the U.S. Antarctic Program.
