By the start of 1944 the Royal Air Force was faced with unacceptably high losses in Bomber Command. De Havilland’s answer to the problem was the DH98/II Deerfly, built by De Havilland Canada and powered by four Packard Merlin engines.
Using technology perfected in building the pre-war DH91 Albatross transport and using local Canadian timbers, the Deerfly was rushed into production. The aircraft carried a crew of two or three in an enlarged fuselage, and could carry the same bomb load as a Lancaster over the same radius of action, but 60 mph faster and at a higher altitude. The Deerfly needed no defensive armament, being fast, with an excellent rate of climb, and being very difficult to see with radar due to its wooden airframe.
