Shaped Charge

   Also found in: Dictionary/thesaurus, Acronyms, Wikipedia 0.01 sec.
shaped charge [′shāpt ′chärj]
(ordnance)
An explosive charge with a shaped cavity that forces the impact of the explosion to the front so that there is an armor-piercing force. Also known as cavity charge.

Shaped Charge 

a charge of explosive matter with a conical, spherical, or wedge-shaped hollow whose action is based on a cumulative effect.

The purpose of the shaped charge is the controlled destruction of solid materials. Shaped charges with a conical hollow—the height of which is equal to the diameter of the hollow opening and which has a metal lining (with a thickness of about one-thirtieth of the diameter of the hollow opening)—will pierce steel armor whose thickness is approximately four times the diameter of the hollow opening. Shaped charges are used in armor-piercing shells, in blasting caps, and for pulverizing odd-shaped rocks in quarries and breaking up other objects. A typical example of the use of shaped charges in military activity is in antitank rocket projectiles. These shells have a large hollow head which ensures that the shell explodes at the right distance from the obstacle so that its armor-piercing effect will be maximal. Another example is the linear shaped charge, which is elongated and has a metallined wedge-shaped hollow in the form of a trough. These charges are used to cut metal sheets, cores, and design elements, in particular when taking down surface and underwater structures.

[ILLUSTRATION OMITTED] Switzerland's Ruag Land Systems has developed a simple wire-mesh screen called the Lasso (Light Armour System against Shaped Ordnance) which, Ruag claims, can provide up to 60% protection against the RPG-7 anti-tank grenade's shaped charge.
EFPs are a deadly type of shaped charge that is particularly effective at penetrating armor.
