Formation of an EFP warhead. USAF Research Laboratory.. An explosively formed penetrator (EFP), also known as an explosively formed projectile, a self-forging warhead, or a self-forging fragment, is a special type of shaped charge designed to penetrate armor effectively, from a much greater standoff range than standard shaped charges, which are more limited by standoff distance.
High-explosive anti-tank (HEAT) is the effect of a shaped charge explosive that uses the Munroe effect to penetrate heavy armor. The warhead functions by having an explosive charge collapse a metal liner inside the warhead into a high-velocity shaped charge jet; this is capable of penetrating armor steel to a depth of seven or more times the ...
A shaped charge is an explosive charge shaped to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons , penetrating armor , or perforating wells in the oil and gas industry .
A B61 nuclear bomb in various stages of assembly; the nuclear warhead is the bullet-shaped silver canister in the middle-left of the photograph.. A warhead is the section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb.
The applications of Octol are generally military; e.g., shaped charges and warheads that are used in guided missiles and submunitions. Octol is somewhat more expensive than RDX-based explosives, such as Composition B and Cyclotol. The advantage of Octol is that it significantly reduces the size and weight of the explosive charge required.
When the submunition detects a target, its 1.5 kg LX-14 explosive charge is detonated to project an explosively formed penetrator that has enough energy to penetrate the thin top armor of most main battle tanks up to a range of around 152 m. If the submunition reaches the ground before it finds a target it self-destructs.
An example of a tandem charge warhead is used by the 9M133M Kornet-M missile system However, tandem charges are more useful against explosive reactive armour, less so against the non-explosive reactive armor, since their inner liner is not explosive itself and thus not expended by the small forward warhead of tandem-charge attack.

Additionally, polymer-bonded explosive compositions containing HMX are used in the manufacture of missile warheads and armor-piercing shaped charges. HMX is also used in the process of perforating the steel casing in oil and gas wells. The HMX is built into a shaped charge that is detonated within the wellbore to punch a hole through the steel ...
