The T3s were standard Maritime Commission tankers. The T3-S was a simplified version of the T3-S2 with a single shaft and less powerful engines, giving it a speed of 15 knots, which was sufficient for Navy tanker service but not for a fleet oiler. As with the T3-S2 the Navy was so anxious to obtain modern tankers that it took over the contracts for the first few T3-Ss that were completed. These became the Chiwawa class.

Units in the Pacific:

About eight T3-S tankers were completed as civilian merchant ships. The remainder are tabulated under the Chiwawa class.
