Chobham Armor

M1 Abrams was the first manufactured vehicle to include Chobham armor. Chobham armor was initially developed by the British tank research center on Chobham Common, Surrey, and consists of ceramic tiles sheathed in a metal framework and open space. Along with M1 Abrams tanks, Challenger 1 & Challenger 2 tanks use the armor. The framework that binds the ceramic tiles is manufactured in large blocks. This shape gives the tanks a unique angled appearance. The form is most noticeable with the turrets.
