USS Knox (FF-1052)

The Knox-class design was derived from the Brooke-class frigate modified to extend range and without a long-range missile system. The ships had an overall length of 438 ft (133.5 m), a beam of 47 ft (14.3 m) and a draft of 25 ft (7.6 m). They displaced 4,065 long tons (4,130 t) at full load. Their crew consisted of 16 officers and 211 enlisted men.[2]

The ships were equipped with one Westinghouse geared steam turbine that drove the single propeller shaft. The turbine was designed to produce 35,000 shp (26,000 kW), using steam provided by two C-E boilers, to reach the designed speed of 27 kn (50 km/h; 31 mph). The Knox class had a range of 4,500 nmi (8,300 km; 5,200 mi) at a speed of 20 kn (37 km/h; 23 mph).[3]

The Knox-class ships were armed with a single 5-inch (127 mm)/54 caliber Mark 42 gun. They mounted an eight-round ASROC launcher between the 5-inch gun and the bridge. Close-range anti-submarine defense was provided by two twin 12.75-inch (324 mm) Mk 32 torpedo tubes. The ships were equipped with a torpedo-carrying DASH drone helicopter; its telescoping hangar and landing pad were positioned amidships aft of the mack. Beginning in the 1970s, the DASH was replaced by a SH-2 Seasprite LAMPS I helicopter and the hangar and landing deck were accordingly enlarged. Most ships had an eight-cell BPDMS missile launcher added in the early 1970s.[4][3]

She was laid down 5 October 1965, by Todd Pacific Shipyards, Seattle, Washington; launched 19 November 1966; sponsored by Mrs. Peter A. Sturtevant, the granddaughter of Commodore Knox; and was commissioned on 12 April 1969, with Commander William A. Lamm in command.[1]

Knox performed search and rescue operations and provided evacuation, blockade, and surveillance support, when necessary, for the Pacific Fleet. In April 1975, Knox participated in Operation Eagle Pull, the evacuation of Phnom Penh, Cambodia.[5] Knox was redesignated a frigate on 30 June 1975 as FF-1052.[1]

Decommissioned on 14 February 1992, Knox was stricken from the Naval Vessel Register on 11 January 1995. NAVSEA temporarily placed Knox on the donation hold list but removed her from the list around 2003. Knox was sunk as a target off Guam, during "Exercise Valiant Shield" (2007) on 7 August 2007.[1]
