There are three primary defensive methods for protecting against HEAT rounds. This is a rod that holds the imitator ahead of the round so that the explosive jet “stands off” far enough to properly form. A spinning HEAT round from a rifled barrel is less effective than a stable one so the fins are used to keep the round on target. There are two significant additions to modern heat rounds. This can penetrate more than seven to ten times the diameter of the charge in hardened steel armour. A thin sheath of copper (or other materials but copper is most prevalent) can be added and the plasma jet formed by the copper will move at 14 km/s and reach a temperature of 925C.
This works by concentrating the explosive force into a jet of force along the axis of the hollowed area. This states that a conical hollow in the forward end of an explosive will greatly increase the penetration effect.
The basic design element of the HEAT round is the Munroe or Neuman effect. HEAT was also used in the handheld Bazooka, PIAT, Panzerschrek, and Panzerfaust. By the middle of that year, Germany had also adapted the KwK 37 gun of the Panzer IV and the Stug III to fire HEAT. This was launched from a “Cup” launcher on the end of a rifle and was introduced in 1940. The first HEAT weapon may be considered to be the British No 68 Rifle Grenade /AT. High Explosive Anti Tank (HEAT) (sometimes referred to as Hollow Charge or Shaped Charge) rounds evolved from the Swiss inventor Mohaupt who was able to demonstrate using a shaped explosive charge to increase penetration. Chemical or explosive rounds use the power of an explosive to defeat the target armour. Kinetic rounds use sheer power and speed to punch through armour. Anti Infantry (Canister, HE) and anti bunker/material (HE, MPATs, ARM) are not covered in this article.)ĭuring and after the Cold War, anti-tank ammunition fell into two broad categories: Kinetic and Chemical. This article focuses only on Anti Tank ammuntion. (Note: There are a large number of different types of tank ammunition.
