The British "Victory Bomber" was a Second World War design proposal by British inventor and aircraft designer Barnes Wallis while at Vickers-Armstrongs for a large strategic bomber. This aircraft was to have performed what Wallis referred to as "anti-civil engineering" bombing missions and was to have carried his projected 22,000 lb (10,000 kg) "earthquake bomb" to strategic targets in Germany. The Victory Bomber was considered extremely ambitious: the Royal Air Force (RAF) at that time not yet having introduced four-engine heavy bombers, and to give the necessary performance, the Victory Bomber was to have six engines and was highly specialized to its role.
The project was studied in detail, the bomber proceeding to wind tunnel testing while the earthquake bomb to equip it was tested on representative models. The Air Ministry chose not to proceed with development of the Victory Bomber, terminating it in May 1941. No prototypes were built, but the Avro Lancaster filled a similar role and was fitted with a similar armament array. The Lancaster used Wallis' Tallboy, Grand Slam and bouncing bomb during strategic "anti-civil engineering" missions, such as Operation Chastise, the "Dambusters" mission.
