Breguet 410

The Breguet 410 was a French bomber of the early 1930s. Not many of these twin-engined sesquiwing biplanes were built. At least one Breguet 413, one of its variants, was sold to the Spanish Republican Air Force during the Spanish Civil War.

Development and design
The Breguet 410 was a sesquiplane prototype designed by Breguet Aviation in order to meet the requirements of the Technical Aeronautic Service ( Service Technique de L'Aéronautique ) of the French government towards the end of the 1920s for a bomber and reconnaissance plane type designated as Multiplace de Combat. It had a steel frame covered with duralumin; its armament was two front and two rear 7.7 mm Lewis machine guns and it could carry a bomb load up to 1300 kg.

Only one unit of the first variant, the Breguet 410, was built which was ignored in favor of the competing Amiot 143 despite its combat qualities. Other plane prototypes built by other companies such as the Blériot 137 and the SPCA 30 underwent a similar fate as the Breguet 410. Most its later developments or variants never went past the prototype stage.

Operational history
The only Breguet 410 unit flew in 1931 and was fitted with two Hispano-Suiza 12Nb motors. Developments followed though, with an upgraded and slightly modified version, the Breguet 411, which flew in 1932. Like its predecessor this Breguet aircraft was again rejected by the French government.

The Breguet 413 was an improved version, fitted with more powerful Hispano-Suiza 12Ybrs engines. Four units were constructed for the Armée de l'Air, the first one of which flew in February 1933. At least one of these became part of the Escadrille Internationale and was sent to the Spanish Republican Air Force at the beginning of the Civil War in that country, but its fate is unknown.

A further development followed, the Breguet 414. It was fitted with Gnome-Rhône 14Kdrs engines and its first test flight was in November 1933. Only one prototype was built which crashed in France in 1940.

There is not sufficient information regarding the Breguet 420 project. Thus the fact whether the Breguet 414 was the same unit that was upgraded becoming the Breguet 420 prototype remains doubtful.
