The Blériot 127 (or Bl-127) was a French bomber aircraft of the 1920s and 1930s, developed from the Blériot 117 escort fighter. It was a large monoplane of conventional configuration that featured open gunner's positions in its nose and at the rear of its two underwing engine nacelles. The wing airfoil was of sufficient thickness that these latter positions could be accessed from the fuselage in flight.

Forty-two aircraft were operated by the Armée de l'Air from 1929 until 1934, by which time they were thoroughly obsolete.

Variants[edit]

  • 127/1 - Prototype with Hispano-Suiza 12Gb W-12 piston engines
  • 127/2 - Main production version, fitted with two Hispano-Suiza 12Hb V-12 piston engines.
  • 127/3 - Single prototype of night bomber version.
  • 127/4 - Single conversion of 127/2 with revised undercarriage.
  • 137 - All-metal high-wing prototype designed in order to meet the requirements of the Technical Aeronautic Service ( Service Technique de L'Aéronautique ) of the French government towards the end of the 1920s for a light bomber and reconnaissance plane type designated as Multiplace de Combat.[1] The only two units of this plane built were ignored in favor of the competing Amiot 143. Other Multiplace de Combat plane prototypes built by other companies at the time such as the SPCA 30 and the Breguet 410 underwent a similar fate as the Blériot 137.[2]
