Chobham Armour

Chobham armour is the name informally given to a composite armour developed in the 1960s at the British tank research centre on Chobham Common, Surrey, England. The name has since become the common generic term for ceramic vehicle armour. Other names informally given to Chobham Armour include "Burlington" and "Dorchester."

Although the construction details of the Chobham Common armour remain a secret, it has 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. Only the M1 Abrams, Challenger 1, and Challenger 2 tanks have been disclosed as being thus armoured. The armour was first tested in the context of the development of a British prototype vehicle, the FV4211. Despite being a British invention, for financial reasons the armour type was first implemented on the American tank.

Famous quotes containing the word armour:

    The man whose silent days
    In harmless joys are spent,
    Whom hopes cannot delude,
    Nor sorrow discontent:

    That man needs neither towers
    Nor armour for defence,
    Nor secret vaults to fly
    From thunder’s violence.
    Thomas Campion (1567–1620)
