The Gourdou-Leseurre GL.30 was a racing aircraft built in France in 1920 which formed the basis for a highly-successful family of fighter aircraft based on the same design. The GL-30 was a parasol-wing monoplane with retractable undercarriage and a Bristol Jupiter engine. In 1922 this was used to develop a fighter under the designation GL.31.
Made by Gourdou-Leseurre.
