Faced with equipment shortages, a hostile desert environment, and superior enemy planes, Coningham's management system, through judicious deployment of his squadrons, gradually achieved air superiority in the North African campaign. In particular, Coningham developed the use of fighter-bombers, able to fight as fighter planes in the air or in bombing and strafing attacks of enemy ground targets. Coningham developed an efficient ground support system to keep planes flying, and a command and control system to allow ground observers to radio in air attacks. Coningham's Western Desert Air Force, in continuous air attacks of enemy ground targets, was instrumental in stopping the enemy offensive at El Alamein in July 1942. Coningham formed a close relationship with the new commander of the British Eighth Army, General Bernard Montgomery. Montgomery and Coningham recognised the importance of joint operations. The air power doctrine devised by Coningham is the basis of modern joint operations doctrine. The dominance of the Allied air force was a critical factor in the British victory at the Second Battle of El Alamein in November 1942. Coningham's doctrine of tactical air power would reach its fruition in early 1943, when RAF and USAAF fighter-bombers and bombers attacked enemy land forces.
