Victory Bomber

[5] Wallis allegedly said that "irreparable damage could be inflicted on the strategic communications of the German Empire by ... ten or twenty machines within the course of a few weeks".

[2] However, the deployment of Wallis' concept was not immediately possible, for there was no existing Royal Air Force (RAF) bomber that would be capable of carrying such a weapon.

However, Lord Beaverbrook committed support for the project, and co-operation from both the Ministry of Aircraft Production and the Road Research Laboratory would be forthcoming to aid Wallis in developing his plans.

[6][7] In August 1940, the Aeronautical Research Committee permitted the use of a wind tunnel at the National Physical Laboratory in Teddington to perform tests to develop the penetration bomb.

[8][10] The bomber design is not believed to have been developed beyond construction of a large wooden wind tunnel model which survives today at Brooklands Museum.

[13] In July 1940, Wallis was summoned to meet with Beaverbrook, and was able to briefly present the Victory Bomber concept to him, who in turn referred it for further study.

[14] On 1 November 1940, Sir Charles Craven, Vickers' Managing Director, wrote to Lord Beaverbrook to suggest that he give backing to both the bomb and the Victory Bomber.

Defensive armament was minimal; speed and height would be its chief defence with one quad-gun turret in the tail position for any fighter aircraft that did attempt to reach it.

Wallis himself acknowledged that the accuracy called for to employ the penetration bomb from 40,000 ft (12,000 m) was difficult to achieve;[3] specifically, there was an assumption that around 25 percent of days throughout the year would be suitable for performing bombing missions in, but that during such missions the benefits of being undisturbed from ground-based anti-aircraft fire would lead to equivalent accuracy to conventional bombers flying at 15,000–20,000 ft (4,600–6,100 m) under gunfire.
