Notes

- Double-hull type.
- 5 ballast tanks.
- The larger conning tower allows the 2 (standard from now on) periscopes to
    have a larger stroke than her predecessors.
- Because the construction was delayed the design could be adjusted according
   to the latest World War I experiences. Therefore: External-traversing tubes, which meant
   an extra danger during depth charge attacks, where not installed; Sail enlarged;
   4 meter longer periscope; 8,8 cm instead of 7,5 cm gun.
