The first three submarines of the class were laid down in March–April 1911 as Seawolf, Nautilus and Garfish, and were renamed H-1, H-2 and H-3 while still under construction. They were commissioned in December 1913/January 1914. H-1 ran aground and was wrecked off the coast of Mexico on 12 March 1920, while the remaining eight submarines were decommissioned in late 1922, and laid up in the Reserve Fleet. Finally struck from the Navy List in 1930, they were sold for scrap in 1931 and 1933.
