The Navy did not adopt the H 52 but put forward a specification which called for supercharging to 4,000 m (13,100 ft) and a stalling speed of less than 100 km/h (62 mph).
In the place of spars it had six span-wise cells formed from vertical alloy plates separated by spacers close to the wing surface.
The cells were vertically expanded at the centre of the wing structure to form the cockpit area of the fuselage between the engine and the rear part.
The H 100 had a pair of floats close in length to that of the fuselage and fitted with mid-length steps and water rudders at the stern.
The H 110 carried a pair of Darne 7.5 m (0.295 in) calibre machine guns, mounted in the wings just above the floats and firing outside the propeller disc.
