Ship project history: This class introduced metal bridges into US submarine practice. At the same time, power was actually reduced in the interest of greater engine reliability (to 480 or 600bhp from the previous 800-1200bhp). The success of this step led to a decision to use more moderate power for the 'O', 'R' and 'S' classes, and to the re-engining of many existing submarines. Even so, U-boat type diesels were adopted after World War One. This was the last US class designed without deck guns until 1946.

Modernizations: None.

Naval service: No significant events.
