The Curtiss P-40 was an American single-engine, single-seat, all-metal fighter and ground attack aircraft that first flew in 1938. It was used by the air forces of 28 nations, including those of most Allied powers during World War II, and remained in front line service until the end of the war. By November 1944, when production of the P-40 ceased, 13,738 had been built, all at Curtiss-Wright Corporation's main production facility at Buffalo, New York.
P-40s first saw combat with the British Commonwealth squadrons of the Desert Air Force (DAF) in the Middle East and North African campaigns, during June 1941. The Royal Air Force's No. 112 Squadron was among the first to operate Tomahawks, in North Africa, and the unit was the first to feature the "shark mouth" logo, copying similar markings on some Luftwaffe Messerschmitt Bf 110 twin-engine fighters. The logo was most famously used on P-40s by the Flying Tigers in China. - http://en.wikipedia.org/wiki/Curtiss_P-40
