The USS Koelsch (FF-1049) was a Garcia-class frigate constructed by Defoe Shipbuilding Company in Bay City, Michigan. Laid down on February 19, 1964, and launched on June 8, 1965, she was sponsored by Miss Virginia L. Koelsch, niece of the late Lt. (j.g.) John K. Koelsch, for whom the ship was named. After completing builders’ trials on Lake Huron in April 1967, she departed Bay City in May and was commissioned on June 10, 1967, at the Boston Navy Yard. Designed as a versatile ocean escort, Koelsch featured a teardrop-shaped sonar dome and was initially equipped with antisubmarine warfare (ASW) systems, including the Antisubmarine Warfare Ship Command and Control System (ASWC&CS). She was also prepared for helicopter operations, with modifications made to accommodate a manned helicopter, specifically the Kaman SH-2 Seasprite, later added in her overhaul. Throughout her service, Koelsch conducted numerous deployments and exercises across European, Atlantic, Mediterranean, and Middle Eastern waters. Her operational history includes significant NATO exercises such as Sharem and display operations, as well as patrols and surveillance in the Atlantic and Mediterranean regions. Notably, Koelsch served in the Middle East Force, conducting patrols in the Persian Gulf and participating in exercises with Iranian and Pakistani navies, including port visits to Africa, the Middle East, and Europe. Her missions often focused on antisubmarine warfare, surveillance, and maritime security, exemplifying her role as a flexible and mobile ocean escort. The vessel underwent multiple overhauls and system upgrades, including the installation of advanced sonar and radar systems, and modifications to enhance helicopter and weapon capabilities. She was also the recipient of awards such as the Rhode Island Navy League’s Anti-Submarine Warfare Trophy. Decommissioned in May 1989, USS Koelsch was leased to Pakistan, renamed Siqqat (F-267), but the lease was canceled in 1994 due to Pakistan’s nuclear program. She was returned to U.S. custody, stricken from the Navy Register, and ultimately scrapped in Hong Kong. Named in honor of Lt. (j.g.) John Kelvin Koelsch, a Medal of Honor recipient and Korean War hero, the vessel’s insignia symbolized strength, versatility, and valor, reflecting her motto: "Valor [and] Versatility."
