It was followed by more effective combinations of warhead and delivery systems in the US 'Bazooka', and the British PIAT spigot mortar. The first HEAT warhead was a rifle grenade, the British No 68 grenade. Observers from several countries realised that the principle was not new but an application of the shaped charge. The development of HEAT weapons was spurred by some Swiss inventors who exhibited a 'new' weapon before the war. Where HEAT is used as the warhead for guided missiles, rifle grenades and spigot mortars, warhead size is not a limiting factor. WOMBAT (105 mm) or Carl Gustav (66mm) have proven effectiveness. Recoilless rifle weapon designs use lighter barrels and carriages and the combination of a light recoiless rifle gun and HEAT round e.g. Increasing the caliber to allow a greater diameter makes the gun heavier. A further problem is that if the warhead is contained inside the barrel, then its diameter is restricted to the caliber of the gun.

The centrifugal forces disperses the jet, as a result the warhead design needs to be modified for use with rifled guns.

HEAT rounds are less effective if they are spinning the normal method for giving a shell accuracy. In general HEAT rounds can expect to penetrate armor of 150% to 250% of their width, although modern versions claim numbers as high as 700%. As the penetration continues through the armor, the width of the hole decreases leading to a characteristic 'fist to finger' penetration, where the size of the eventual 'finger' is based on the size of the original 'fist'. The key to the effectiveness of a HEAT round is the diameter of the warhead. The jet material is formed by a cone of metal foil lining, usually copper, though tin foil was common during the Second World War. Spacing is critical, as the jet disintegrates and disperses after a relatively short distance, usually well under 2 metres. The jet moves at hypersonic speeds (up to 25 times the speed of sound) in solid material and therefore erodes exclusively in the contact area of jet and armor material. High explosive anti-tank, more commonly known as HEAT, rounds are made of an explosive shaped charge that uses the Neumann effect (a development of the Munroe effect) to create a very high velocity jet of metal in a state of superplasticity that can punch through solid armor.
