Design
Chobham's precise mechanism for defeating HEAT was uncovered in the 1980s. High speed photography showed that the ceramic material shatters as the HEAT round penetrates, the highly energetic fragments destroying the geometry of the metal jet generated by the hollow shaped charge, greatly diminishing the penetration. The effectiveness of the system was amply demonstrated in Desert Storm, where not a single British Army Challenger tank was lost to enemy tank fire. However, one was destroyed by friendly fire on March 25, 2003 killing two crew members after a HESH round detonated on the commander's hatch causing high velocity fragments to enter the turret. Chobham-type armour is currently in its third generation and is used on modern western tanks such as the British Challenger 2 and the American M1 Abrams.

Famous quotes containing the word design:
“We find that Good and Evil happen alike to all Men on this Side of the Grave; and as the principle Design of Tragedy is to raise Commiseration and Terror in the Minds of the Audience, we shall defeat this great End, if we always make Virtue and Innocence happy and successful.”
—Joseph Addison (1672–1719)
“If I commit suicide, it will not be to destroy myself but to put myself back together again. Suicide will be for me only one means of violently reconquering myself, of brutally invading my being, of anticipating the unpredictable approaches of God. By suicide, I reintroduce my design in nature, I shall for the first time give things the shape of my will.”
—Antonin Artaud (1896–1948)
“What but design of darkness to appall?—
If design govern in a thing so small.”
—Robert Frost (1874–1963)
