USS Leahy (DLG/CG-16) was the lead ship of a new class of destroyer leaders in the United States Navy. Named for Fleet Admiral William D. Leahy, she was commissioned on 4 August 1962 as DLG-16, a guided missile frigate, and reclassified as CG-16, a guided missile cruiser, on 30 June 1975. From 1962 to 1976, Leahy operated as a unit of the Atlantic Fleet and from 1976 to 1993 as a unit of the Pacific Fleet. She made six Mediterranean deployments (Sixth Fleet), two UNITAS Latin America cruises and eight Western Pacific deployments (Seventh Fleet), completed three Panama Canal transits, and crossed the equator over a dozen times. She traveled the seas from the easternmost end of the Mediterranean to the westernmost edge of the Indian Ocean. She steamed far north to Leningrad, Russia, and the Aleutian Islands; and far south for two passages through the Straits of Magellan. Over the course of her sixteen major deployments, Leahy made port calls on six continents—North America, South America, Europe, Asia, Africa and Australia. Leahy served longer than any other ship of her class. After more than 31 years of active service all over the globe, the "Sweet 16" was decommissioned on 1 October 1993. After another 11 years in the reserve fleet, she was scrapped in Brownsville, Texas, in 2005.
