The A43 Black Prince arose from the need for a "Super Churchill", armed with the powerful 17 pounder anti-tank gun that could augment the firepower of the standard Churchills within the tank brigades. The resulting machine would prove to be both durable and reliable during evaluation testing, and promised to be an effective weapon in the hands of users. However, the war would come to an end before production could commence, and the AFV Division of the Ministry of Supply would instead concentrate on newer designs for the post-war era. This book provides an in-depth examination of the legendary Black Prince, and its place within the history of British tank design.
