The importance of the role air power played in the months leading up to D-Day cannot be overstated, with the Allied powers knowing that securing superiority of the skies over the proposed landing beaches could be the difference between success and failure of the entire operation. That being the case, Allied air forces were committed in ever-increasing numbers from the end of 1943, attacking airfields, supply infrastructure and other strategic targets, and mounting hundreds of diversionary attacks. This was all intended to keep German forces guessing as to the location of the anticipated invasion, but all the time diminishing their ability to respond to the landings when they came. With so many Allied aircraft expected to be in the air supporting Operation Overlord, Allied Commanders were concerned about the possibility of their aircraft coming under attack from friendly forces both in the air and from anti-aircraft units on the ground. They issued a directive that all aircraft (with some exceptions, including four-engined heavy bombers) be painted with identification markings around their wings and rear fuselage, under the strictest levels of security. The order to begin applying markings to troop transport, aircraft was not issued until 3rd June 1944, with other units receiving their instructions the following day. This move placed additional pressure on airfield staff already working at maximum capacity. On D-Day itself, over 13,000 individual sorties were flown by Allied aircraft in support of the amphibious landings and although around 127 aircraft were lost for various reasons during those operations, it’s thought that the adoption of invasion makings significantly reduced numbers succumbing to incidents of friendly fire on that momentous day. Although the Luftwaffe were conspicuous by their absence on D-Day itself, they fought tenaciously in the weeks and months which followed, highlighting the fact that they were far from finished.Model kits included: Supermarine Spitfire Mk.IXc 26 parts.North American P-51D Mustang 53 parts.Messerschmitt Bf109G-6 41 parts.Hawker Tempest Mk.V 72 parts.Focke-Wulf Fw190A-8 53 Parts.
