The Morane-Saulnier BB was a military observation aircraft produced in France during World War I for use by Britain’s Royal Flying Corps. It was a conventional single-bay biplane design with seating for the pilot and observer in tandem open cockpits. The original order called for 150 aircraft powered by 110-hp Le Rhône 9J rotary engines but shortages meant that most of the 94 aircraft eventually built were delivered with 80 hp Le Rhône 9C rotaries instead.
