The Anniversary of the de Havilland Mosquito’s first flight, which took place on the 25th of November back in 1940.
The de Havilland D.H. 98 Mosquito took to the air for the first time on November 25th 1940, flying from the company’s base and airfield at Hatfield. The Mosquito was then introduced into RAF service a year later, on 15th November, 1941. The Mosquito was to stay in production from 1940 up until 1950, with over of 7,700 being produced in that period before its final retirement from service in 1963. The design of the Mosquito in mainly wood was such that it did not use metals needed for other aircraft and projects and could be built in different factories both in the U.K., Australia and Canada, using carpenters with no previous real aviation experience.
The Mosquito was the first true multi-role combat aircraft and was both fast and agile, happy at both high altitudes and low level and in all the multitude of rolls it was destined to fulfil, Fighter Bomber, Night Fighter, Hi-Speed unarmed precision Bomber, Path Finder, Maritime Anti-Shipping Strike, Photo and weather Reconnaissance, Target Tug. It was also used by the British Overseas Airways Corporation as a hi-speed courier/transport to carry hi-value cargo from neutral Countries as well the occasional passenger in the bomb bay.
Geoffrey de Havilland and his team of designers at Hatfield developed the Mosquito as a private venture after the Ministry of Aircraft Production had wanted the project scrapped but the idea of a fast light hi-speed multi role aircraft appealed to the RAF and ACM Sir Wilfrid Freeman.
The design concept was very different to the RAF’s policy of metal construction heavily armed four engine bombers. The design was of a mainly wooden construction powered by two engines (Rolls Royce Merlin) and without the drag normally crated by addition of gun turrets for defensive armament. With all the additional weight and crew it was able to meet its designers’ aim to use high-speed to out run enemy fighters as its defense, which showed as losses of the Mosquito in action was a mere 2-3% compared to the heavy bombers combat losses of up to 10%, it achieved this as it proved to be 20mph faster that the Spitfire. By 1943 It could carry a bombload of 4,000 lbs (Cookie) to Berlin. The armaments carried varied with the different variants and there intended rolls.
