Manitowoc
A city and county in eastern Wisconsin, located on the shore of Lake Michigan.
The first Manitowoc (PF-81), originally designated PG-169, was reclassified PF-61 on 15 April 1943 ; laid down under Maritime Commission contract by Globe Shipbuilding Co., Superior, Wis., 26 August 1943 ; launched 30 November 1943 ; sponsored by Mrs. Martin Georgenson ; delivered to the Maritime Commission 27 September 1944 ; ferried to New Orleans, La., via the Sault Sainte Marie Canal and the Mississippi River ; and acquired by the Navy and placed in service 24 October 1944.
Between 29 October and 5 November Manitowoc steamed to Boston where she was placed out of service 5 November and converted by the Boston Navy Yard for use as a weather patrol ship. Manitowoc commissioned at Boston 5 December 1944, Lt. Comdr. J. A. Martin, USCG, in command. During late December and early January 1945, she underwent shakedown off Bermuda. After returning to Boston 20 January 1945, she joined Escort Division 34 for duty as a weather station ship in the North Atlantic.
Departing Boston 2 February, Manitowoc reached Argentia, Newfoundland, 5 February ; the following day she sailed on her first weather patrol. Equipped with special radio transmitters and specialized meteorological equipment, she relieved Woonsocket (PF-32) 8 February and began patrolling her assigned station, During the next 2 weeks she transmitted valuable weather data used to compile weather forecasts for both the North Atlantic and Western Europe in the closing weeks of the Allied defeat of Nazi Germany. Relieved on station 24 February, she returned to Argentia the 26th.
Prior of V-E Day, Manitowoc made two more weather patrols in the stormy North Atlantic, which carried her from Newfoundland to Iceland. In addition, she patrolled the sea lanes in her station against German submarines, once the menace of the North Atlantic.
After the end of the war in Europe, Manitowoc continued patrols in the North Atlantic where she served primarily as an air-sea rescue ship. Between 29 May and 10 February 1946 she completed seven such patrols, including a 5-day run in mid-November during the return flight to England of Prime Minister Clement Attlee. During an earlier patrol in late July she provided medical aid for the Panamanian merchantman SS Yemasee, and while on the same patrol 2 August, her medical officer performed an emergency appendectomy on a seriously ill crewman from the Swedish merchant ship SS San Francisco.
After returning to Boston from her final patrol 10 February, Manitowoc decommissioned at Boston 14 March 1946 and immediately recommissioned on loan as a Coast Guard ship, Lt. Wesly L. Saunders, USCG, in command.
During the next 5 months Manitowoc served in the Atlantic out of Norfolk, Va., and in the Gulf of Mexico out of New Orleans. She decommissioned at New Orleans 3 September 1946, was sold to France 25 March 1947, and was delivered to a representative of the French Government 26 March 1947. Commissioned in the French Navy as Le Brix (F-15), she served under the French flag until scrapped in 1958.
