The last fighter design of Andre Herbemont to bear the SPAD designation, and intended to participate in the 1934 fighter competition, the Bleriot SPAD 710 was a single-seat, single-bay biplane of all-metal construction with a duralumin monocoque fuselage and an 860hp Hispano- Suiza 12Ycrs 12-cylinder Vee liquid-cooled engine. It had a proposed armament of one engine-mounted 20mm cannon, four wing-mounted 7.5mm machine guns and one aft-firing 7.5mm gun in the rear fuselage.
The Bleriot SPAD 710 embodied inward-retracting main undercarriage members, a completely enclosed cockpit with aft-sliding canopy and a V-type or “butterfly” tail assembly. The initial flight took place in April 1937, and, on 8 June, 300km/h was exceeded in level flight with the undercarriage extended. A week later, on 15 June, tail flutter developed at an altitude of only 200m and the aircraft crashed, killing the pilot, Louis Massotte. Further development was then abandoned.
