Types of T - Tankers
During World War 2 several different tanker types where built.
Amongst them are the following :
-------------------------------------------------------------------------------------
The T-1 tankers were small product carriers, designed to carry gasoline. Almost all of them went either to the U.S. Navy,
as AOGs, or to Britain, for service in a similar role. Many of those under construction at the end of the war were sold im-
mediately: a few can still be seen in the Far East, working in local distribution trades and as bunkering tankers.
Seven shipyards built 113 T-1s, led by East Coast Shipyards, in Bayonne NJ, which built 30, Cargill, in Savage MN, which
built 18, Todd Houston (14), Barnes-Duluth (12), Todd Galveston (12), St. John's River (12), Jones Panama City (6), Todd
Tacoma (5) and Lancaster Iron Works (4).
