Breguet BUC

Fokker monoplanes were taking a toll on the formations of Breguet-Michelin 4, BLM, and BUM bombers and a solution was sought in the form of a lighter, better-armed version also derived from the BU3 prototype. The first answer came in the Breguet BUC, a smaller, cannon-armed aircraft, also known as the Breguet 7. ("BUC" stands for Breguet, Canton-Unné, Chasse (fighter)). The Breguet BLC and Breguet BC are related planes with different engines.

It is likely that only a few were built, as the design was already obsolete by early 1916.
