The USS Aylwin (FF-1081) was a Knox-class frigate of the United States Navy, notable for its versatile service from the early 1970s through the early 1990s. Laid down on November 13, 1969, at Avondale Shipyard in Westwego, Louisiana, and launched on August 29, 1970, the vessel was commissioned on September 18, 1971, at Boston Naval Shipyard. As a Knox-class, she measured approximately 438 feet in length with a beam of about 47 feet, and a draft of around 24 feet, with a displacement of roughly 4,000 tons. Her propulsion system consisted of a combination of a steam turbine and a boiler, providing a maximum speed of approximately 27 knots. Throughout her service, USS Aylwin undertook numerous deployments, including her first Mediterranean cruise in December 1972 with the 6th Fleet, participating in NATO exercises and antisubmarine warfare (ASW) operations. She was extensively involved in NATO exercises such as "National Week" and "Dawn Patrol," and conducted patrols in the Mediterranean, Red Sea, Persian Gulf, and the Atlantic. Notable during her service was her participation in operations off Lebanon during the Lebanese Civil War, supporting the multinational force and convoying evacuees. She also engaged in freedom of navigation operations near Libya and conducted surveillance and patrol duties during heightened tensions. Aylwin underwent various modifications, including the addition of the Light Air Multi-Purpose System (LAMPS) during a yard period in 1972 and later replacing her missile system with a Phalanx close-in weapon system in 1984. She was reclassified from a destroyer escort to a frigate (FF-1081) on July 1, 1975. Her operational history included intensive training, law enforcement support, and participation in multinational exercises, reflecting her role in Cold War maritime strategy. Decommissioned on May 15, 1992, Aylwin was transferred to Taiwan in 1998, where she was renamed Ning Yang. Her service life highlights her importance as a versatile platform for antisubmarine warfare, maritime patrol, and international naval cooperation during her nearly two decades of active duty.
