Project history: This class was considered successful, apart from engine problems; H1 and H3 failed their first engine endurance runs. H4-H9 were originally ordered by the Czarist Russian government as AG17-20, 27 and 28, but they were purchased for the US Navy in 1918. This class should not be confused with the Electric Boat-built British and Chilean 'H' class.

Modernizations: None.

Naval service: No significant events.

H5 1921
