USCGC GLACIER
U.S. Coast Guard
USCGC Glacier (WAGB-4) was a notable icebreaker originally commissioned by the U.S. Navy in 1955 and later transferred to the United States Coast Guard in 1966. Built to support polar operations, Glacier played a crucial role in Antarctic exploration, conducting scientific missions and resupply operations for Operation Deep Freeze. The vessel's robust construction enabled her to break through thick ice, ensuring year-round access to remote research stations. After over three decades of distinguished service in some of the world's harshest environments, USCGC Glacier was decommissioned in 1987.
