Historical Data

 
 

A further attempt to develop a fleet submarine similar to the K-boats, but with diesel engines for propulsion. These submarines, were by the standards of the day very comfortable, but lightly armed for their displacement.

The original intention was for a class of twenty boats, but a change of thinking on submarine construction, and the very high cost of these boats restricted the class to just three boats.
