The Kennebecs were completed for Socony-Vacuum Oil Company from 1941 as Maritime Commission standard T2-SO tankers. They were based on a successful civilian design used in the Beaumont Canal in Texas, but with Navy subsidies for much more powerful machinery, to permit them to operate as fleet oilers in the event of war. All were immediately taken over by the U.S. Navy when war broke out in the Pacific.

The ships were equipped with eight center and sixteen wing tanks, of which several were modified during navalization to carry gasoline, diesel fuel, and lubricating oil. They had three main cargo pumps, each with a capacity of 1900 gallons per minute (7200 liters per minute). This allowed the vessel to unload in about 16 hours. There were also three stripping pumps with a capacity of 400 gallons per minute (1500 liters per minute).

None were lost in the Pacific.
