The ASW-centric steam-powered Knoxes, a 46-strong class, were in service with the Navy from 1969, and gave 25 years of hard service, with the final member of the breed, USS Moinester (FF-1097), decommissioned 28 July 1994 and transferred to Egypt soon after. The 51 more general-purpose OHPs began arriving in 1977 with the final unit, USS Kauffman (FFG-59), decommissioned 8 September 2015, leaving an unfilled “frigate gap” in the U.S. Navy for the first time since WWII.

An aerial stern view of the decommissioned battleship Iowa-class USS New Jersey (BB-62) and seven decommissioned Knox class frigates (and a carrier just peeking in off camera to the left) tied up at the Ship Intermediate Maintenance Facility at Puget Sound Naval Shipyard, WA., on 17 May 1993.
New Jersey was decommissioned for her fourth (and final?) time on 8 February 1991 and has since 15 Oct 2000 been a museum at 62 Battleship Place, Camden, New Jersey
The seven much smaller (438-foot/4,260-ton) Knox class
destroyer escorts fast frigates were from a large class of 46 steam powered tin cans rapidly decommissioned by the Navy in the early 1990s with the last of their kind, USS Truett (FF-1095), paying off on 30 July 1994.
As far as trivia goes, Truett lives on in the Royal Thai Navy as the HTMS Phutthayotfa Chulalok (FFG 461)— now say that five times fast.
