| Notes | Developed as a tank destroyer the Challenger mounted the excellent 17 pdr, the motive behind this was to give armoured units a tank in which to be able to engage the new heavier models of German tanks, the chassis was a lengthened version of the Cromwell and a had new turret to house the large gun. Production totals never exceeded 200 due to the availability of the Sherman Firefly. The Challenger served alongside the Cromwell in armoured reconnaissance regiments. |
