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. 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.
