Handley-Page V/1500

The Air Board wanted a plane that could bomb Berlin from England, and the Handley-Page V/1500 was the result. It was roughly based on the O/400, but the wings were 25% longer. Push-Pull Rolls-Royce engines were mounted in tandem, giving the V/1500 twice the horsepower of its predecessors. Flight testing of the prototype continued from May through June 1918, and it was only with delivery of the second plane in October 1918 that development resumed. Only three were flying at the time of the Armistice, though there were grand visions of sixty V/1500 squadrons to be flying in 1919.
