Demolition Shaped Charge
The Charge, Demolition, Shaped, 150mm is designed to make holes of considerable depth and breadth in a variety of materials. It consists of a 150mm diameter conical steel liner with three removable legs which provide a standoff of 145mm. The Charge, Demolition, Shaped, 150mm contains 3.1 kg of HE and its total mass is 4.9 kg.
Target Material Depth of Hole (mm) Armour Plate 178 Mild Steel 250 Hard Rock (Granite) 380 Reinforced concrete 760 Soft rock (Sandstone) 910
Shaped Charges and Explosived Disposal
Shaped Charges are used as a remote clearing device.
COPPER CONE - Using the jet-forming copper cone, the charge produces a jet which may be used to pierce holes, typically through 75mm (3 in) of mild steel or greater thicknesses of concrete or brickwork. It may be used for causing the detonation or deflagration of steel-cased ammunition without any risk of inadvertent disturbance of the target before firing. The usual explosive load is between 20 and 50g.
COPPER EXPLOSIVELY-FORMED PROJECTILE - A wide angled copper cone, essentially a slightly domed disc, generates an explosively-formed projectile (EFP) which may be used to penetrate robust targets at much greater ranges than the jet-forming cone. This enables the VULCAN to be used as a de-armer and disruptor device. It punctures 10mm thick steel at a range of at least 1,500mm.
ALUMINIUM PROJECTILE The aluminium projectile is able to deliver a powerful blow to shell fuses and bomb pistols thus removing them or jamming their mechanisms. It thus provides a low-priced, disposable, alternative to de-armers using heavy steel barrels.
MAGNESIUM INCENDIARY CONE - The jet formed by this cone is less penetrating than that formed by the copper cone but it is a less powerful initiator of detonation. It is used to penetrate even thick-walled shells or bombs and ignite the explosive or pyrotechnic filling. In this application it is much less likely to cause inadvertent high order detonation than other, more conventional, charges. It thus provides a reliable means of bringing about a "low order" deflagration event. The usual explosive load for this purpose is between 30 and 40g.
WATER PROJECTILE A conical cavity is formed in the explosive, water is poured into the cavity, and a plastic cone is inserted to retain the water. The charge thus becomes a shaped charge, able to penetrate steel-cased munitions with thicknesses of up to 10mm, and to disperse their contents with minimal risk of detonation. Charges are quickly assembled and robust.
