Glacier was the first icebreaker to make her way through the frozen Bellingshausen Sea, and most of the topography in the area is named for her crew members. When built, Glacier had the largest capacity single armature DC motors ever installed on a ship. Glacier was capable of breaking ice up to 20 feet (6.1 m) thick, and of continuous breaking of 4-foot (1.2 m) thick ice at 3 knots.

USCGC Staten Island (WAGB-278) was a United States Coast Guard Wind-class icebreaker. Laid down on 9 June 1942 and launched on 28 December 1942, the ship was commissioned on 26 February 1944, and almost immediately afterward transferred to the Soviet Union, under the Lend Lease program, under the name Severny Veter, which loosely translates as Northwind, until 19 December 1951. When returned to the United States Navy, she was designated USS Northwind until 15 April 1952, when she was renamed USS Staten Island to distinguish her from her successor USCGC Northwind (WAGB-282) which had been laid down shortly after she was lent to the Soviet Union. The ship was transferred to the U.S. Coast Guard as USCGC Staten Island in February 1965, and served until November 1974, before being scrapped.
USCGC Katmai Bay (WTGB-101) is a United States Coast Guard Cutter, and the lead ship of the Bay-class of icebreaking tugboats. At 140 ft (43 m), she is designed to have greater multi-mission capabilities than the 110' Calumet-class Harbor Tug (WYTM). She is homeported in Sault Ste Marie, Michigan, operating in support of the much larger USCGC Mackinaw (WLBB-30).
USCGC Biscayne Bay (WTGB-104) is a United States Coast Guard Cutter and an icebreaking tug. She is based at Coast Guard Station St. Ignace with a primary area of operation in the Straits of Mackinac including Mackinac Island, Mackinac Bridge, and the northern portions of Lakes Michigan and Huron and occasionally Lakes Superior, Erie and their connecting rivers.

USCGC Penobscot Bay is the seventh of nine United States Coast Guard 140-foot Bay-class icebreaking tugs. Homeported in Bayonne, New Jersey, the primary missions of Penobscot Bay and her crew are Domestic Icebreaking and Ports, Waterways, & Coastal Security. During the winter months, Penobscot Bay is responsible for providing search and rescue capabilities to the ice-covered areas in New York City and the Hudson Valley, as well as throughout coastal New England. The cutter also facilitates the safe navigation of commercial product, including gasoline and heating oil, through the ice-choked Hudson River from New York City to Albany. All Bay-class cutters, including Penobscot Bay, use a low-pressure-air hull lubrication or bubbler system that forces air and water between the hull and ice. This system improves icebreaking capabilities by reducing resistance against the hull, reducing horsepower requirements.
USCGC Bristol Bay (WTGB-102) is the second vessel of the Bay-class tugboats built in 1978 and operated by the United States Coast Guard. The ship was named after the body of water formed by the Alaskan peninsula, which emptied into the Bering Sea.
