Compass Island

Compass Island

An island in Penobscot Bay off the coast of Maine.
(EAG-163: dp. 18,000 (f.); 1. 663'; b. 76'; dr. 26'; s. 20
k.; cpl. 214; cl. Compass Island)

Compass Island (EAG-163) was launched 24 October 1953 as Garden Mariner by New York Shipbuilding Corp., Camden, N.J. sponsored by Mrs. H. A. Smith
acquired by the Navy 29 March 1956; and commissioned 3 December 1956, Commander J. A. Dare in command.

The first mission of Compass Island was to assist in the development and evaluation of a navigation system independent of shore-based and celestial aids, a necessary adjunct of the ballistic missile program. She operated along the eastern seaboard testing equipment and training personnel until 13 March 1968 when she sailed from New York for experiments in the Mediterranean, returning to New York 17 April to resume her east coast operations. A dramatic example of her work was provided when Nautilus ( S S N-57 1 ), using the Shipboard Inertial Navigational System tested by Compass Island, made a submerged cruise beneath the Arctic ice pack touching exactly at the North Pole 3 August 1968. On 10 September 1958 Compass Island entered New York Naval Shipyard for overhaul and installation of additional navigational equipment to be tested. With this new equipment, she continued her east coast and Caribbean cruising through 1960.
