The Michelin brothers volunteered to build copies of the Breguet BU3 prototype, but they envisioned the plane would serve better as a bomber than a fighter. Fifty were built with the 220hp Renault engine and designed the Breguet-Michelin BLM (aka the BM2). They served in 1915-1916 with the similar Breguet-Michelin BUM and the Breguet-Michelin 4 in some of the earliest dedicated bombing units.
