The Potez 31 was designed to meet the requirements of
the 1925 C2 programme calling for a two-seat night
fighter and diurnal reconnaissance-fighter. Not flown
until 1929, and closely resembling the Potez 25M monoplane
variant of the Potez 25 army co-operation biplane,
the Potez 31 was a parasol monoplane of wooden construction
with fabric covering. Embodying the facility
developed for preceding types of accepting either Hispano-
Suiza or Lorraine-Dietrich W-type water-cooled
engines, the Potez 31 was tested with both the 500hp
HS 12Mb and the 450hp L-D 12Eb. Armament consisted
of two fixed forward-firing 7.7mm guns, two similar
weapons on a flexible mount in the rear cockpit and a
fifth gun firing through a hatch in the rear cockpit floor.
Development of the Potez 31 was terminated with the
discontinuation of the C2 programme.
