Contains: 3x Challenger Tanks
As German tank developers continued to create heavier and heavier tanks with thicker armour, Allied forces looked for new options to defeat them. The appearance of the Tiger I was the last straw and prototype 17 pounder anti-tank guns were rushed to the front to give British forces an effective counter.
The development of the Challenger was one of the many options pursued and used a lengthened Cromwell hull with its powerful Rolls Royce Meteor engine, and a new turret design that was large enough to accommodate the large gun and a crew of four. A fifth crew member, the driver, remained in the hull.
