The Dutch submarine Hr. Ms. O 1 built using this design
The submarine was called an improved submarine torpedo boat identical with the Adler and Plunger submarines which were built for the US Navy. This design included all modifications used in the Fulton and the ones not applied while the Fulton was already completed. Displacement 104 (light)-123 (submerged) tons with a length. The steel made hull was designed for a diving depth of 300 feet. In practice was actually dived to a depth of 160 feet without deformation. For safety reasons was no cast iron used for parts subjected to pressure while she was submerged.
Fitted out with a 4 single acting cylinders gasoline inverted Marine type with an electric spark ignition. Fired by ordinary gasoline stored in a tank located forward away from all sources of heat. The company claimed that the fuel tank and the pipelines connected with the engine were such tight that leaking was impossible. The electric motor was a waterproof Marine type.
Average achievements of the design on official trials. The guaranteed achievements were somehow slightly lower.
In the so-called light condition was the maximum speed 8,5 knots, endurance 35 hours and the range 300 nautical miles. With the economical speed of 6,5 knots was the endurance 70 hours and the range 450 nautical miles.
In the so-called intermediate condition was the maximum speed 7,5 knots, endurance 25 hours and the range 262 nautical miles. With the economical speed of 6 knots was the endurance 70 hours and the range 420 nautical miles.
In the so-called submerged condition carrying a periscope was the maximum sustained sped 6,75 knots, the endurance 3,5 hours and the range 24 nautical miles. With the economical speed of 4,5 knots was the endurance 22 hours and the range 100 nautical miles. With the intermediate speed of 6 knots was the endurance 7 hours and the range 42 nautical miles.
Tactical diameter is 75 (submerged)-150 (surfaced) yards. Able to dive within 50 seconds.
There were 3 steering stations available, on deck, in the bronze made conning tower and the submarine herself. Just one crewmember controlled the diving station for submerging and controlling the submarine.
The armament consisted of just one submerged 45cm fixed torpedo tube in the bow for which 3-5metres long torpedoes were carried (one already in the tube).
