The Gourdou-Leseurre Type A retrospectively named the GL.1 was a prototype fighter aircraft built in France in 1918. It was a conventional parasol-wing monoplane with fixed tailskid undercarriage with main units connected by a cross-axle. The pilot sat in an open cockpit. Construction was of fabric-covered wood and steel. Initial flight testing revealed performance superior to most contemporary biplane fighters and led to an order of 100 aircraft being placed.
