Design and development

In late 1932, the Société des Avions Bernard proposed to build a floatplane fighter to meet the requirements of the French Navy for a shipboard fighter suitable for operation from the catapults of its Battleships and Cruisers. The Bernard design, the H.52, was a mid-winged monoplane based on its Bernard 260 landplane fighter, using the same wings, rear fuselage and tail surfaces as the earlier design. It was of all-metal construction, principally duralumin, with a monocoque fuselage and stressed skin cantilever wings that were integrally constructed with the centre fuselage. Leading edge slots and large flaps were fitted to the wing to lower its landing speed, while its undercarriage consisted of two main floats. A single supercharged Gnome-Rhône 9Kdrs radial engine powered the aircraft [1][2][3]

The first of two prototypes flew on 16 June 1933, with the second flying in 1934. No production followed, with Bernard choosing to develop a new fighter to meet the requirements of the French Navy, the Bernard H.110. This had a similar layout, with wooden wings and a more powerful engine fitted, but had no more success in attracting orders than the H.52, the French Navy eventually selecting the Loire 210.[1]
