Representing an intermediate stage between the Potez XV and Potez 25, despite its later type number, the Potez XXVII appeared in 1924. It was a two-seat biplane in the A.2 observation category and combined the engine, fuselage, fin, rudder and cross-axle landing gear of the Potez XV with a tailplane, balanced elevator and unequal-span wings similar to those of the Potez 25.
The type was built for export only, Poland obtaining 20 machines in 1925 and subsequently building 155 under licence at the P.W.S. works; some were still serving as trainers in 1936. Romania also procured 30 Potez XXVII aircraft in 1926.
