Breguet 6 / Bre 6 Ca2
The Type 6 (Bre 6 Ca2) two-seat escort fighter of 1916 was a 225hp Salmson A9 water-cooled nine-cylinder radial engined counterpart of the Renault-powered Type 5, and resulted from a fear that Renault engine production would prove inadequate to meet demands. The Type 5 airframe was modified to take the Salmson engine mounted immediately above the rear undercarriage legs and driving the propeller by means of an extension shaft, the power plant being entirely enclosed. Armament of the Type 6 fighter normally consisted of a short-barrel 37mm Hotchkiss cannon in the forward fuselage. Performance, weights and dimensions were essentially similar to those of the Type 5.
