Soviet 125 mm HEAT BK-14. The general public remained in the dark about shape charge warheads, even believing that it was a new secret explosive, until early 1945 when the US Army cooperated with the US monthly publication Popular Science on a large and detailed article on the subject titled "It makes steel flow like mud". [6]
The Javelin uses two shaped-charge warheads in tandem. The weak, smaller diameter HEAT precursor charge detonates the ERA, clearing the way for the much larger diameter HEAT warhead, which then penetrates the target's primary armor. A two-layered molybdenum liner is used for the precursor, and a copper liner for the main warhead.
The Army revealed that a 40 mm precursor shaped-charge warhead was fitted on the tip of the TOW-2 and TOW-2A collapsible probe. [60] Usually, the front charge is somewhat smaller than the rear one, as it is intended primarily to disrupt ERA boxes or tiles. Examples of tandem warheads are US patents 7363862 [61] and US 5561261. [62]
The RPG-18 fires a 64 mm PG-18 high-explosive anti-tank (HEAT) warhead mounted on a small rocket able to engage targets within 200 meters. The warhead self-destructs six seconds after launch, placing a limit on range even if a sight was used that was effective with targets beyond 200 meters. The RPG-18 can penetrate up to 300 mm of conventional ...
The current model produced by the Russian Federation is the RPG-7V2, capable of firing standard and dual high-explosive anti-tank (HEAT) rounds, high explosive/fragmentation, and thermobaric warheads, with a UP-7V sighting device fitted (used in tandem with the standard 2.7× PGO-7 optical sight) to allow the use of extended range ammunition.
A laser-proximity fuze located in the front half of the nose measures the range between target and missile. At the correct range, the small nipple on the front nose containing a small HEAT warhead is ejected forward from the missile body to pre-detonate the reactive armor followed by the detonation of main HEAT warhead.
A marine preparing to fire an M31 from an M1 rifle An M31 HEAT rifle grenade fitted to an M14 rifle. The M31 HEAT is a fin-stabilized anti-tank rifle grenade designed in the late 1950s to replace the Belgian ENERGA rifle grenade which was adopted by the US Army and US Marines as an emergency stop-gap measure during the Korean War.
The warhead contains 1.16 kilograms (2.6 lb) of thermobaric mixture, with an explosive yield roughly equal to that of 3 kilograms (6.6 lb) of trinitrotoluene . The solid rocket booster of the warhead was taken from the RPG-26 and the fuse taken from the TBG-7 warhead used by the RPG-7. The warhead has a stated penetration ability of 300 ...
