First flown in 1931, the Bréguet 410 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 bombload up to 1300 kg.

[2] The Bréguet 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 aircraft, which it referred to as Multiplace de Combat.

[3] Only one unit of the first variant, the Bréguet 410, was built, which was passed in favour of the competing Amiot 143 despite its combat qualities.

The Bréguet 410 was an all-metal sesquiplane biplane bomber; the primary materials from which the fuselage was constructed included high-tensile steel and duralumin.

[6] The bombardier, who also doubled as the navigator, had a folding seat with a trapdoor directly in front of them; this was used both for aiming or for emergency egress, for which they were provided with a parachute.

[7] In order to provide favourable fields of fire for the gunners aft of the wing led to the adoption of relatively novel devices.

Specifically, the shape of the fuselage is discontinuous in terms of both plan and profile to accommodate a constriction just behind the aft gun ring, which was claimed to considerably increase the position's field of fire, especially downwards.

[10] The leading edges of the ribs consisted of stamped frames of either duralumin or steel, which were placed either in pairs or individually.

[10] The undercarriage was equipped with oleopneumatic shock absorbers while brakes were present to help slow the aircraft during landings.

[18] 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.
