Despite being the inventor of the tank and responsible for campaign-winning tactics, by the start of the Second World War the United Kingdom had fallen well behind other nations in the design and build of armoured vehicles. Here, William Suttie uncovers the history of tank design from a government perspective and the decisions and failures that led to that state of affairs, and details the formation of the Fighting Vehicles Research and Development Establishment at Chertsey. Known as the Tank Factory, the Chertsey establishment sought to ensure that the United Kingdom became world-leading in the field of military vehicle research and design, and that the British Army would never be underprotected or outgunned again. Drawing on unpublished sources and photographs, this fascinating book reveals the establishment's history, its groundbreaking research and its inventions and designs, including first-hand insights from those who worked there.
