Design and development

The 5/2 was based on de Monge's earlier Lumière-de Monge racer (possibly designated de Monge 5/1) and was of metal construction with both wood and metal skinning.[1] The 5/2 was powered by a 300 hp (224 kW) Hispano-Suiza 8Fb inline piston engine.[1] The parasol-wing fighter retained the ability inherited from the Lumière-de Monge to attach stub-wings to convert the aircraft to a sesquiplane.[1] The aircraft was intended to use two forward-firing synchronised machine guns but they were not fitted to the prototype.[1] The 5/2 was first flown in 1923, but after testing, it was assessed as too advanced for use and development was abandoned.[1]
