The Morane-Saulnier AC, also known as Morane-Saulnier Type AC and MoS 23, was a French fighter of the 1910s.
The AC was conceived in mid-1916, being derived from the Type N via the unbuilt Type U. It differed from earlier single-seat Morane-Saulnier aircraft in that it had ailerons for lateral control rather than wing warping, and because of its rigid wing bracing, with a wire braced truss of steel tubes supporting the wings from below. [1] It appeared in autumn of that year, and was found to be aerodynamically clean.
The AC's first flight is unrecorded, however it is assumed that it was late summer 1916. After initial testing thirty aircraft were ordered for the Aviation Militaire. Although of advanced design and good performance, the AC was considered inferior to the SPAD S.VII and therefore was not adopted in quantity. Two examples were provided to the Royal Flying Corps for evaluation.

The Morane-Saulnier N, also known as the Morane-Saulnier Type N, was a French monoplane fighter aircraft of the First World War. Designed and manufactured by Morane-Saulnier, the Type N entered service in April 1915 with the Aéronautique Militaire designated as the MoS-5 C1. It also equipped four squadrons of the Royal Flying Corps, in which it was nicknamed the Bullet, and was operated in limited numbers by the 19th Squadron of the Imperial Russian Air Force.
The Morane-Saulnier L, or Morane-Saulnier Type L, or officially MoS-3, was a French parasol wing one or two-seat scout aeroplane of the First World War. The Type L became one of the first successful fighter aircraft when it was fitted with a single machine gun that fired through the arc of the propeller, which was protected by armoured deflector wedges. Its immediate effectiveness in this role launched an arms race in fighter development, and the Type L was swiftly rendered obsolete. The original Type L used wing warping for lateral control, but a later version designated Type LA was fitted with ailerons.
The Morane-Saulnier Type P was a French parasol wing two-seat reconnaissance aeroplane of the First World War. Morane-Saulnier built 595 for the French air force, and it was also used by the British until 1916-17.
The Bristol M.1 Monoplane Scout was a British monoplane fighter of the First World War. It holds the distinction of being the only British monoplane fighter to reach production during the conflict.
The Morane-Saulnier M.S.225 was a French fighter aircraft of the 1930s. It was produced in limited quantities to be used as a transitional aircraft between the last of the biplanes and the first monoplane fighters.
The Morane-Saulnier G was a two-seat sport and racing monoplane produced in France before the First World War. It was a development of the racing monoplanes designed by Léon Morane and Raymond Saulnier after leaving Borel and, like its predecessors, was a wire-braced, shoulder-wing monoplane. Construction was of fabric-covered wood throughout, except for the undercarriage struts which were of steel tube.
The Morane-Saulnier AI was a French parasol-wing fighter aircraft produced by Morane-Saulnier during World War I.
The Vickers F.B.12 was a biplane pusher fighter aircraft developed during World War I by Vickers Limited. The failure of the engine for which it was designed, and the obsolescence of the pusher configuration, resulted in its remaining an experimental type only.
The Morane-Saulnier I, also known as the Morane-Saulnier Type I was a French fighter of the 1910s. Essentially a modified Morane-Saulnier N, the Royal Flying Corps possessed a number of them in World War I.
The Morane-Saulnier AF, also known as the Morane-Saulnier Type AF and the MoS 28 was a French First World War single-seat biplane fighter prototype from 1917.
The Morane-Saulnier MoS-121, also known as the Morane-Saulnier MS.121 was a French fighter prototype of the 1920s. It was Morane-Saulnier's first fighter design after World War I.
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. A water-cooled Hispano-Suiza 8A engine was trialled as an alternative in the Type BH, but this remained experimental only. A production licence was sold to the Spanish company Compañía Española de Construcciones Aeronáuticas (CECA), which built twelve fitted with Hispano-Suiza engines in 1916.
The Morane-Saulnier H was an early aircraft first flown in France in the months immediately preceding the First World War; it was a single-seat derivative of the successful Morane-Saulnier G with a slightly reduced wingspan Like the Type G, it was a successful sporting and racing aircraft: examples serving with the French army were used in the opening phases of the war.
The Morane-Saulnier T was a French biplane reconnaissance aircraft in 1916 and produced in small numbers during World War I.
The Morane-Saulnier MS.138 was a military trainer aircraft produced in France in the late 1920s,
The Morane-Saulnier M.S.325 was a French Air Force fighter aircraft built by Morane-Saulnier in 1933 to meet the requirements of 1930 fighter aircraft specification. The design was unsuccessful and was abandoned in 1934.
The Sopwith Swallow was a British parasol wing fighter aircraft of the First World War. A single example was built, but it saw no production, offering no performance advantages over contemporary biplanes.
The Airdrome Morane Saulnier L is an American amateur-built aircraft, designed and produced by Airdrome Aeroplanes, of Holden, Missouri. The aircraft is supplied as a kit for amateur construction.
The Ponnier M.1 was an early French World War I fighter aircraft Most of those produced were operated by the Aviation Militaire Belge. They were deemed unusable by the Belgian ace Willy Coppens and rapidly retired.
The Morane-Saulnier MS.224 was a prototype fighter plane built by Morane-Saulnier in the early 1930s.
