To improve the performance of the Nieuport 10 a re-engined version was developed as the Nieuport 12 with a significantly enlarged upper wing. A Lewis gun was fitted to the rear cockpit for use by the observer, normally on an Etévé ring (known as the Nieuport ring in British service) although early examples used a pedestal mount or half ring. A second Lewis was sometimes fitted to fire over the top wing. Nieuport 12s built by Beardmore used by the Royal Flying Corps were sometimes fitted with a Scarff ring instead of the Nieuport ring, and a synchronizedVickers gun for the pilot. Additional modifications were made to those built by Beardmore.
It could be fitted with either a 100 hp (75 kW) Clerget, 130 hp (97 kW) Clerget 9B engine or 110 hp (82 kW) Le Rhône 9J mounted in the nose.

23 meter Nieuport
Unofficial generic designation for all types listed here based on nominal wing area of 23 square meters.
Nieuport 80 E.2 and 81 E.2
Nieuport 12s were later built in large numbers specifically as training aircraft with the gun ring removed. 8 in designation referred to 80 hp (60 kW) Le Rhône 9C. These differed in having flight controls for just the pilot in the rear seat (81 E.2), or both pilot and passenger (80 E.2).
Nieuport 12 (Beardmore)
Beardmore progressively redesigned the Nieuport 12 during a production run of 50 aircraft so early examples were almost stock but late production examples differed considerably in detail. These were fitted with 110 hp (82 kW) Clerget 9Z and 130 hp (97 kW) Clerget 9B rotaries.
