USS "Thomas C. Hart" (FF-1092) was a "Knox"-class frigate , named for Admiral and Senator Thomas C. Hart. "Thomas C. Hart" (DE-1092) was laid down on 8 October 1971 at Westwego, La., by Avondale Shipyards, Inc.; launched on 12 August 1972; sponsored by Mrs. Reginald Bragonier, eldest granddaughter of Admiral Thomas C. Hart; and commissioned on 28 July 1973, Lt. Comdr. Ronald J. Forst in command. Using only the above description and what you know about the world, "Knox class frigates were designed to escort destroyer class frigates." is definitely correct, incorrect, or inconclusive?
