USS Antrim (FFG-20) was the twelfth ship of the Oliver Hazard Perry class of guided-missile frigates. She was named for Rear Admiral Richard Nott Antrim (1907–1969). Ordered from Todd Pacific, Seattle, Washington on 28 February 1977 as part of the FY77 program, Antrim was laid down on 21 June 1978, launched on 27 March 1979, and commissioned on 26 September 1981.[2]


On 10 February 1983, USS Antrim was conducting a live fire exercise off the east coast of the United States using the Phalanx CIWS against a target drone. Although the drone was successfully engaged at close range, the target debris bounced off the sea surface and struck the ship, causing significant damage and fire from the drone's residual fuel which killed a civilian instructor;[1][3]

Decommissioned on 8 May 1996, she was transferred to Turkey on 27 August 1997. She was stricken from the U.S. Naval Vessel Register on 4 September 1997.

TCG Giresun (F 491)[edit]

The ship serves in the Turkish Navy as TCG Giresun (F 491).

On 16 March 2009, TCG Giresun, along with HDMS Absalon successfully prevented a pirate attack on the Vietnamese cargo ship MV Diamond Falcon from succeeding in capturing the target ship.[4][5] On 6 March 2011, she aided the destroyer USS Bulkeley in the capture of 4 pirates who had attacked the tanker MV Guanabara. The pirates were later flown to Tokyo for trial.
