SS ''John W. Brown'' is a Liberty ship, one of two still operational and one of three preserved as museum ships.〔Sawyer (1985) pp. 1-19, 40-41, 223〕 As a Liberty ship, she operated as a merchant ship of the United States Merchant Marine during World War II and later was a vocational high school training ship in New York City for many years. Now preserved, she is a museum ship and cruise ship berthed at Clinton Street Pier 1 in Baltimore Harbor in Maryland. ''John W. Brown'' was named after the Canadian-born American labor union leader John W. Brown (1867-1941).〔(Cooper, Sherod, ''SS John W. Brown: Baltimore's Living Liberty'', Project Liberty Ship, 1991 ), pp. 2-3.〕 The other surviving operational Liberty ship is in San Francisco, California. A third Liberty ship, SS ''Hellas Victory'' (ex-SS ''Arthur M. Huddell'') is preserved as a static museum ship in Piraeus, Greece. ==Construction== The United States Maritime Commission ordered ''John W. Brown'' as an ECS-S-C1 Maritime Commission Emergency Cargo Ship – the type of ship that would become popularly known as the "Liberty ship" – hull number 312 on 1 May 1941.〔''Live'', publication of Project Liberty Ship, 2013 edition, pp. 4, 8.〕 She was laid down at the Bethlehem-Fairfield Shipyard in Baltimore, Maryland, on 28 July 1942 and – sponsored by Annie Green, the wife of the president of the Industrial Union of Marine and Shipbuilding Workers – was launched on 7 September 1942, the third of three Liberty ships launched at the yard that day. She completed fitting out on 19 September 1942, making her total construction time only 54 days. She required about 500,000 man-hours and cost $1,750,000 to build and was the 62nd of the 384 Liberty ships constructed at the Bethlehem-Fairfield yard.〔''Live'', 2013 edition, p. 6.〕〔Cooper, p. 2.〕 The Worthington Pump & Machine Corporation of Harrison, New Jersey, built ''John W. Brown''s vertical triple expansion steam engine, which cost $100,000.〔''Live'', 2013 edition, p. 4.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SS John W. Brown」の詳細全文を読む スポンサード リンク
