USS Stein
USS Stein (DE-1065) was a Knox-class destroyer escort, later redesignated as a frigate (FF-1065) of the United States Navy. She was named after Tony Stein, the first Marine (of 22) to receive the Medal of Honor for action in the Battle of Iwo Jima.
Stein was laid down on 1 June 1970 at Seattle, Washington, by Lockheed Shipbuilding & Construction Co.; launched on 19 December 1970; sponsored by Mrs. Rose S. Parks; and commissioned on 8 January 1972.
Stein was decommissioned on 19 March 1992 and struck from the Naval Vessel Register on 11 January 1995. She was subsequently transferred to the Mexican Navy and renamed the Armada República Mexicana Ignacio Allende, abbreviated ARM Allende.
The Knox-class was an enlarged derivative of the Brooke-class frigate, omitting the Brooke's expensive Tartar medium range surface to air missiles and the high pressure boilers used by the Brooke and Garcia-class frigate frigates.
The ship was 438 ft (133.5 m) long overall and 415 ft (126.5 m) between perpendiculars, with a beam of 47 ft (14.3 m) and a draft of 25 ft (7.6 m). Displacement was 3,020 long tons (3,068 t) light and 4,066 long tons (4,131 t) full load. Two Babcock & Wilcox boilers supplied steam at 1,200 psi (8,300 kPa) and 950 °F (510 °C) to a Westinghouse steam turbine which drove a single 15 ft (4.6 m) diameter five-bladed propeller. The machinery was rated at 35,000 shp (26,000 kW), giving a design speed of 27 kn (31 mph; 50 km/h).
As built, Stein was equipped with one 5-in/54 caliber Mark 42 gun forward, an eight-round ASROC launcher (with 16 missiles carried) abaft the gun and forward of the bridge, with four fixed 12.75 in (324 mm) Mark 32 anti-submarine torpedo tubes. A helicopter deck and hangar for operating the DASH drone helicopter was fitted aft. The ship's main anti-submarine sensor was the large bow-mounted AN/SQS-26CX low-frequency scanning sonar, while AN/SPS-40 air-search radar and AN/SPS-10 surface search radar was fitted. A Mark 68 Fire Control System, with associated AN/SPG-53 radar controlled the ship's gun.
During the 1970s, Stein was refitted with an eight-cell BPDMS Sea Sparrow surface to air missile launcher aft, while the ship's flight deck and hangar were enlarged to allow a single manned, Kaman SH-2D/F Seasprite LAMPS 1 helicopter to be carried. The ship's sonar suite was enhanced by the addition of an AN/SQS-35 variable depth sonar. By 1985, Stein was fitted with an AN/SQR-18A TACTASS passive towed array sonar, which was towed using the SQS-35 hoist, and by 1990 a 20 mm (0.79 in) Phalanx CIWS replaced the Sea Sparrow launcher.
In Mexican service, the Phalanx CIWS was removed and the Sea Sparrow launcher restored.
