The Bernard H 110 was a single engine, single seat monoplane floatplane fighter designed for a French Navy competition. It flew in 1935 but had only made four test flights when the Bernard company was declared bankrupt, preventing further development.

In the early 1930s the French Navy became interested in catapult launched floatplane fighters and the Société des Avions Bernard produced the twin float Bernard H 52 in response, deriving it from their earlier Bernard 20, 74 and 260 land based fighter aircraft. The H stood for the new Naval Hydravion class. 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). This brought designs from four manufacturers; one of these, the Bernard H 110, was a H 52 development, slightly larger and with a more powerful engine.

The Bernard H 110 had a mid mounted cantilever wing. In plan, it was straight tapered with elliptical tips. Following the methods used on earlier Bernard aircraft, the wing was a single piece structure which incorporated part of the fuselage. In the place of spars it had six span-wise cells formed from vertical alloy plates separated by spacers close to the wing surface. Each cell was separated from the next by wider spacers, all of which were shaped to the airfoil profile. The H 52 was metal skinned but the H 110 was fabric covered as the Navy found this easier to repair. 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. On its trailing edge the wing carried horn balanced ailerons and inboard flaps, with pilot controlled, full span Handley Page slots on the leading edge.
