X-Plane 10.20 – Curtiss P-40E. The Curtiss P-40 Warhawk was an American single-engined, single-seat, all-metal fighter and ground-attack aircraft that first flew in 1938. The P40 design was a modification of the previous Curtiss P-36 Hawk which reduced development time and enabled a rapid entry into production and operational service. The Curtiss P-40E is the last Allison engined of the famous Curtiss fighter. The one presented here was flown by squadron pilot George Kiser of the 49th Fighter Group/8th Fighter squadron during the Aleutians campaign against the Japanese. Credit goes to Bernard Augras for use of his pilot. By Philippe Gastebois.
