Breguet LE



The Breguet LE (Laboratoire Eiffel) single-seat fighter monoplane was aerodynamically an advanced design with emphasis being placed on minimising drag in order to achieve high performance. The basis of the design was produced by the Director of the Laboratoire Eiffel in collaboration with the Breguet design staff, the Breguet company having overall responsibility for translating the basic concept into a prototype.

The first prototype LE was fitted with a 180hp Hispano-Suiza 8Ab eight-cylinder water-cooled engine. Proposed armament consisted of a single 7.7mm Vickers machine gun totally enclosed within the fuselage, although this was never fitted. The LE made a short initial flight at Villacoublay in mid-March 1918, but the undercarriage failed on landing. After repairs, a further flight was made on 28 March, this terminating when the aircraft dived into the ground at full throttle, the pilot, Jean Saucliere, losing his life. Developments of the LE with a 220hp Lorraine-Dietrich and a 300hp Hispano-Suiza 8Fb were proposed, and construction of an airframe to take the latter power plant was nearing completion at the time of the loss of the first prototype, when further work was suspended.
