The USS Galaxy (IX-54) was a diesel motor yacht constructed in 1930 by the Pusey and Jones Company in Wilmington, Delaware. Originally built for Mr. Bernard W. Doyle of Leominster, Massachusetts, the vessel was acquired by the United States Navy on September 8, 1941, and commissioned at East Boston, Massachusetts, on September 20, 1941. Notably, she was the only ship in the U.S. Navy to bear the name "Galaxy." Designed primarily for research purposes, the USS Galaxy was dedicated to underwater sound exploration. Throughout her naval service, she was based entirely at East Boston, operating under the 1st Naval District. Her work involved conducting experimental underwater sound research for the Underwater Sound Laboratory located at Fort Trumbull, New London, Connecticut, as well as projects for the Bureau of Ships and the Harvard Underwater Sound Laboratory. These experimental operations took place mainly in Boston and off New London, with brief deployments off the Delaware breakwaters and in Chesapeake Bay. The vessel's primary role was to facilitate underwater acoustics research, contributing valuable data to the field of sonar and underwater sound detection during World War II. She remained in active service until she was decommissioned and placed "in service" on August 2, 1945, continuing her experimental missions until she was finally taken out of service at Boston on March 25, 1946. Her name was struck from the Navy List on May 1, 1946, and she was transferred to the Maritime Commission on May 20, 1946, for disposal. The USS Galaxy played a specialized role in advancing underwater sound research during her brief but significant naval career, underscoring her maritime significance in the development of sonar technology during World War II.
