The B.F.W. N1 is a two-seat triplane night bomber, of which only one was built. It carried 744kg of bombs, had a 260hp Mercedes D IVa engine, weighed 1,500kg empty and 2,500kg loaded. It was armed with a single parabellum gun for protection.
Exotic in the machine was the double elevator and of course the triplane configuration (two-bay) at this late stage of the Great War. The machine appeared in 1918 in the aftermath of the triplane era.
