The Breguet Type IV refers to a series of tractor-configuration biplanes built by Breguet Aviation between 1911 and 1913. These were the first Breguet aircraft to be produced in quantity and were used by the French Army and the British Royal Flying Corps. This type is notable for its extensive use of metal, which was unusual for an aircraft of its era.
Design and development
[edit | edit source]The Breguet Type IV was developed from the Breguet Type III which had appeared during 1910. It was a tractor biplane with a tricycle undercarriage.
Variants and nomenclature
[edit | edit source]
The Breguet Type IV was produced in a number of variants, differing in their seating arrangement and in the engine fitted. Although Breguet'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]
