HIGH EXPLOSIVE SQUASH HEAD Meaning and
Definition
-
High Explosive Squash Head (HESH) is a type of explosive specifically used in anti-tank warfare. It is a term that is derived from its distinct characteristics and purpose. HESH refers to a projectile or warhead designed to be fired from an artillery gun, tank, or similar weaponry, with the intention of disabling or destroying armored vehicles.
The term "high explosive" indicates that this type of projectile contains a potent explosive substance. Squash refers to the nature of the explosion once the projectile reaches its target. Rather than penetrating the armor, HESH rounds operate by creating an explosion that spreads along the surface of the armored vehicle. This allows the force of the explosion to cause the armor to bend inward and deform, ultimately damaging the vehicle from the inside.
HESH rounds typically consist of a metal shell filled with a high explosive compound, which may vary depending on the specific design and manufacturer. Upon impact, a timed fused detonates the explosive substance, creating a powerful shockwave that spreads over a large area. The main objective is to generate a high-pressure wave that can disrupt the structural integrity of the armored vehicle, causing spalling or damaging internal components.
Due to their unique functioning, HESH projectiles are particularly effective against armored vehicles with relatively thin armor. The ability to deform the armor without necessarily penetrating it makes HESH rounds a valuable tool for military forces seeking to disable or destroy enemy tanks and other armored vehicles.
