GOURDOU-LESEURRE GL-2 (TYPE B) France
  
  By comparison with its progenitor, the GL-1, the GL-2 (Type B) had an entirely new and heavily reinforced wing, new horizontal tail surfaces mounted higher on the rear fuselage, and revised rudder and undercarriage. The 180 hp Hispano-Suiza 8Ab engine was retained and armament comprised two synchronised 7,7-mm Vickers guns. The number of pairs of inclined wing bracing struts was increased from two to four, one pair attaching to the wing at half-span and another at three-quarter-span, the cantilevered portion thus being only one-quarter of the half-span. This resulted in an extremely rigid structure, the wing load factor being 10.4 compared with 3.5 for the GL-1. Twenty GL-2s were ordered for the Aeronautique Militaire and built by Mayen et Zodiac. The first was delivered to Villacoublay in late November 1918. Subsequent aircraft were fitted with a taller rudder and enlarged fin to rectify a directional control deficiency, but with the termination of hostilities, Aeronautique Militaire interest in the GL-2 waned and development was cancelled.

An Interesting French Parasol Monoplane: Although the Parasol type of monoplane had a comparatively short vogue during the War, the type has many advantages, and it is more than probable that it will be revived for civilian flying. Our photograph shows the French Gourdon-Leseurre, fitted with 180 h.p. Hispano-Sujza engine. It will be noted that the wing bracing is unusual, struts being employed instead of the usual lift wires. This obviates the necessity for anti-lift wires above the wing. The speed of this machine is said to be 260 kilometres per hour (about 135 m.p.h.)

First of the Gourdou-Leseurre fighters to enter production, the GL-2 was just too late to serve in World War I.
