Ship project history: In these submarines the growth in size was reversed; the Submarine Flotilla considered them a 'reversion of type without justification'. They were the first US submarines with diesel engines, which gave considerable trouble; they had to be re-engined in 1915. They also were the first in USN with bow planes, and first USN submarines with radios. This class showed a typical pre-1917 American concentration on high underwater speed, which continued through the 'S' class of World War One.

Modernizations: None.

Naval service: No significant events.
