In October 1941, the Western Desert Air Forces had 16 squadrons of aircraft (nine fighter, six medium bomber and one tactical reconnaissance) and fielded approximately 1,000 combat aircraft by late 1941. By the time of the Second Battle of El Alamein, the DAF fielded 29 squadrons (including nine South African and three USAAF units) flying Boston, Baltimore and Mitchell medium bombers; Hurricane, Kittyhawk, Tomahawk, Warhawk and Spitfire fighters and fighter-bombers. There were over 1,500 combat aircraft, more than double the number of aircraft the Axis could field.
