===World War I===
In [[World War I]], the US Navy contracted for 18 refrigerated ships for hauling provisions to the troops in Europe. They were launched 1918 and 1919 as the war was ending and were nearly all scrapped by 1933 in the [[Great Depression]] as an economy move. Most were built in [[Baltimore Dry Dock and Shipbuilding Corporation|Baltimore Dry Dock]] in [[Baltimore, Maryland]], [[Moore Dry Dock Company]] in [[Oakland, California]], and Standard SB Co. in [[Shooters Island]], New York.<ref name=ShipbuildingHistory>{{cite web |url=http://shipbuildinghistory.com/history/merchantships/wwii/rtypeships.htm |title=R-Type Refrigerated Cargo Ships |work=Merchant Ship Construction in U.S. Shipyards |publisher=Shipbuilding History |date=12 February 2008 |access-date=12 February 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120509213500/http://shipbuildinghistory.com/history/merchantships/wwii/rtypeships.htm |archive-date=9 May 2012 }}</ref>
