Project history

Enlarged versions of the 40-footers were ordered in mid-1916. They were generally similar, but to identify the wide variety of engine types used they were given additional suffixes.

Modernizations

None

Naval service

12 boats were sent in January, 1919 to Caspian sea. All were abandoned then and captured by White or Red Russian forces.
