Vickers Windsor
The Vickers Windsor was a Second World War British four-engine heavy bomber, designed by Barnes Wallis and Rex Pierson at the Vickers-Armstrongs factory at Brooklands.
Only three examples (the original Type 447 plus successive prototypes known as Type 457 and Type 461) were built. This was due to refinements in the existing Lancaster bomber, rendering it suitable for the role for which the Windsor had been designed. The first prototype flew on 23 October 1943, the second on 15 February 1944, and the third on 11 July 1944. All three were built at Vickers’ secret dispersed Foxwarren Experimental Department between Brooklands and nearby Cobham. The two latter prototypes were tested until the end of the Second World War, when further development and production were cancelled.
