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 in 4 August 1962 as DLG-16, a frigate, and reclassified as CG-16, a cruiser, on 30 June 1975. 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.
