"Flight Lieutenant A R Costello of No. 112 Squadron poses with his Curtiss Kittyhawk at Sidi Heneish in Egypt, April 1942. If any aircraft came to symbolise the Desert Air Force it was the rugged, American-built P-40, known to the RAF as the Tomahawk and Kittyhawk. No. 112 Squadron famously decorated its aircraft with ‘sharkmouth’ nose art. Early versions lacked high-altitude performance, which made them vulnerable to the Messerschmitt Bf 109F, but the Kittyhawk went on to become an effective ground attack aircraft."
