Design work began in 1942 regarding the Archer, a self-propelled anti-tank gun meant as a stopgap until a full-time solution might be found.

Utilizing armor-piercing rounds, it might defeat 192mm of armor at 914 meters, enough to pose ample danger to any German armor associated with day. Production began in 1944, and Archers were delivered to the British Army's Armoured and Infantry Divisions, whom began utilizing it from October.
