 A total number of 11,461 aircraft is most often quoted, notably by Andrews & Morgan (1988); however, they appear to have totalled incorrectly as, using their own data, the total is 11,462.There is some question over several individual aircraft, so the actual total may be a few either side of this figure.In combination, the Wellingtons and 846 Warwicks represent over 75% of the total number of aircraft built by the Vickers-Armstrongs company.
