The Curtiss P-40 served the RAF under two main designations: Tomahawk and Kittyhawk, depending on the variant. Early models - the P-40B and P-40C -were delivered as Tomahawk I, IIA, and IIB starting in 1940. These aircraft had twin .50 cal nose guns and four .30 cal wing guns but lacked self-sealing tanks and armour protection, limiting their combat survivability in Europe. However, they were useful for reconnaissance and training, and saw some operational service with Army Cooperation Command. Later and more advanced versions - the P-40D through P-40N - were supplied under the name Kittyhawk (Mk I - IV). These aircraft featured heavier armament, better protection, and improved engines. They formed the backbone of several RAF and Commonwealth squadrons, particularly within the Desert Air Force, where their durability and firepower made them effective in the low-level fighter-bomber role. Over 3,000 P-40s served in the RAF and Commonwealth air forces, flying in the Middle East, North Africa, Burma, and Italy. The aircraft was robust and easy to maintain, though it lacked the high-altitude performance of German fighters.
