| The Ingalls Shipbuilding Corp.,
                    Pascagoula, Miss., launched the fourth Glacier (AGB-4) and commissioned 27 May 1955 Comdr.
                    E. H. Maher in command. Glacier's shakedown cruise
                    and maiden voyage were combined in her important role in Operation Deep Freeze 1. Her
                    first encounter with the ice came in  December 1955
                    when, after breaking through the Ross Ice Pack,
                    Glacier subsequently continued 400 miles west to break ice into an off-loading site for
                    the establishment of the Naval Air Facility at McMurdo Sound. Glacier returned to Boston,
                    her home port, 6 May 1956 after these accomplishments.  
                     The ship returned to McMurdo Sound 28 October 1956 as  spearhead for Deep Freeze
                    II. After supply deliveries there and at Little America, she led seven other Navy ships
                    from New Zealand through the ice pack to the two Antarctic base sites.  
                    During Deep Freeze III and the IGY of 1957-58,
                    Glacier participated as a launching platform for extensive "rockoon" test during
                    which balloon-lifted rockets gained information useful to the "Explorer" space
                    satellite program. 
                    The summer of 1958 found Glacier at the opposite end of the
                    earth as she escorted ships participating in Operation Sunec for
                    the resupply of North Polar  radar and weather
                    stations. By November of that same year, however, she was again near the South Pole at
                    McMurdo Sound, and after supplying the base steamed to Little America V to begin
                    deactivation of that station. Fifth of the Navy's Antarctic support operations, Deep
                    Freeze 60 (for the season 1959-60) took the ship once more to McMurdo and a tour of
                    exploration into the Bellingshausen Sea. 
                    The Icebreaker departed Boston 13 October 1960 on her sixth
                    Antarctic voyage and reached Port Lyttleton, New Zealand, 21 November to unload cargo.
                    Most of December was spent breaking a 21-mile channel through McMurdo Sound to  open the way for the
                    thin-hulled supply ships. Following the return voyage to Wellington for repairs and to
                    receive the Navy Unit Commendation for her Bellingshausen achievement of the preceding
                    expedition, she again entered the ice-choked Amundsen. Work continued until March 1961
                    when she sailed for Boston, arriving 27 April.  
                    Underway again 8 October 1961 for Deep Freeze 62,
                    she loaded cargo at Port Lyttleton in early November and encountered the Ross Sea ice pack
                    13 November, reaching McMurdo Sound by the end of the month. She returned to New Zealand 6
                    March 1962 and subsequently put in at Boston 5 May after steaming 36,000 miles. 
                    The busy ship stood out of Boston 17 September 1962 for
                    Deep Freeze 63, entering the pack ice 6 November and reaching the edge of the fast bay ice
                    of  McMurdo Sound a
                    week later. The thickness of the ice necessitated repairs at Wellington. Glacier was again
                    churning through McMurdo Sound en route to McMurdo Station by 31 December 1962 . She
                    continued operations off  McMurdo Station through
                    1965. One of her many duties was to keep the channel open for supply ships. On 29 December
                    1965, Atka (AGB-3) and Burton Island (AGB-1) assisted her in pushing an iceberg out of the
                    shipping lane. After further participation in her 11th Operation "Deep Freeze,"
                    Glacier returned to the home port, Boston, Mass., in the late spring of 1966.  
                    On July 1 1966 Glacier was struck from the Navy list after
                    transfer to the Coast Guard 30 June 1966.

                    The Glacier is currently anchored in Suisun Bay, CA,
                    with the Federal Reserve   Fleet, the only
                    remaining Ice Breaker afloat of the original U. S. Navy Ice Breaker Fleet. She was visited
                    in 1993 by shipmate John Willard and in 1995 by shipmate Bob Dietrich. Both men took a
                    group of pictures.  |
