The Breguet Type IV was an aircraft built by Breguet Aviation. It was first flown in 1911, and was the first Breguet aircraft to be produced in quantity. It was used by the French Army and the British Royal Flying Corps. It is notable for the extensive use of metal in its construction, unusual in an aircraft of its time.
Design and development
[edit]The Bréguet Type IV was developed from the Bréguet Type III which had appeared during 1910. It was a tractor biplane with a tricycle undercarriage.
Variants and nomenclature
[edit]
The Bréguet Type IV was produced in a number of variants, differing in their seating arrangement and in the engine fitted. Although Bréguet's earlier aircraft were referred to using a type number, the aircraft produced after the Type III were generally referred to using an airframe number and a letter/number combination denoting the type of engine fitted.[1]
