HESH is an acronym that stands for "high-explosive squash head," which refers to a type of explosive ammunition used in military artillery and anti-tank weapons. HESH rounds consist of a large caliber shell filled with a combination of a high explosive filler and a plastic explosive tamping layer. The term "squash head" describes the shape of the explosive charge in the shell, which is flat at the front.
The primary purpose of HESH ammunition is to defeat armored targets, particularly tanks and armored vehicles. When a HESH round impacts the surface of a target, the explosive charge detonates and creates a shockwave that spreads across the surface, causing a large area to deform. This deformation leads to the formation of cracks and fractures in the armor, eventually reducing its structural integrity.
Unlike other types of armor-piercing rounds that rely on penetration, HESH rounds rely on the effect of the shockwave to cause damage. As a result, they are often effective against armored vehicles with relatively thin or layered armor.
HESH ammunition is commonly used by various armed forces around the world due to its versatility and effectiveness. The impact of HESH rounds can also cause spalling or fragmentation of the armor, endangering the crew inside the target vehicle. However, advances in armored vehicle design and the development of reactive armor have diminished the effectiveness of HESH rounds in some cases.
