Chobham Armor was the name informally given to a composite armor developed in the 1960s at the British tank research center on Chobham Common, Surrey, England. The name has since become the common generic term for ceramic vehicle armor. Other names informally given to Chobham Armour include "Burlington" and "Dorchester."
Although the construction details of the Chobham Common armor remained a secret, it had been described as being composed of ceramic tiles encased within a metal matrix and bonded to a backing plate and several elastic layers. Due to the extreme hardness of the ceramics used, they offer superior resistance against shaped charges such as high explosive anti-tank (HEAT) rounds and they shatter kinetic energy penetrators. During the Global War, the M1 Abrams, Challenger 1, and Challenger 2 tanks have been disclosed as being thus armored. Since the introduction of Robotechnology, most mecha has been using some form of this type of armor.
