Power plant was a 300 hp Hispano-Suiza 8Fb eight-cylinder liquid-cooled engine, a radiator flanked the cockpit on each side. It carried two synchronized 0.303 in (7.7 mm) Vickers guns. It featured pronounced forward sweep of the lower wing to improve the forward and downward view of the pilot.
Despite good performance during official trials, in the summer of 1919, choice fell on the similarly-powered Nieuport 29 and further development of the Descamps 27 was abandoned. The fate of the aircraft is unknown."
