In April 1943 de Havilland suggested the carrying of one 1,814 kg (4,000 lb) bomb, so-called "Cookie", a thin-cased, cylindrical high-explosive bomb with devastating blast effect, by the Mosquito. A number of B.Mk.IVs were converted to carry this weapon, which made necessary bulged bomb bay doors. In this configuration the Mosquito's all-up weight was 11,340kg. On February 23, 1944 the first three "Cookies" dropped by Mosquitos fell on DÃ¼sseldorf.
