The ANF Les Mureaux 110 and its derivatives were a family of French reconnaissance aircraft developed in the 1930s. They were all-metal, parasol-wing monoplanes with the pilot and observer in tandem open cockpits. The type was widely used in the Battle of France, but were all scrapped soon afterwards.

Development

The ANF Les Mureaux 110 originated with a French air ministry requirement for an aircraft to replace the Breguet 19 in Armée de l'Air service in the "R2" two-seat reconnaissance role.[1] Two slightly different variants, the 110 and 111 were presented to the air force for evaluation, and were soon ordered into production.

The first mass-production version was the 113 in 1933, of which 49 examples were purchased. This was supplanted in production by the 115 in 1935 and the 117 later than year. Both these series were given light bombing capability as well.

Operational history

The 113 entered service initially with the Armée de l'Air's reconnaissance Groupes, followed by the observation Groupes, and finally replacing the ageing Potez 25s in the Groupes Aériens Régionaux reserve units. It was followed into service by the 117 and 115. From 1934 to 35, 40 of the original 113s were converted into night fighters and used to replace the Breguet 19s still in service with France's two nightfighter Groupes.

By the outbreak of World War II, the 115 equipped nine Groupes Aériens d'Observation, and the 117 nine more. By April 1940, 11 aircraft had been lost in action, leaving 228 on strength at the beginning of the Blitzkrieg in May. By the time of the French armistice with Germany on June 25 only 62 remained, some of which were in North Africa.
