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.
