Why Can't Squash Rounds Be Fin Stabilized Like HEAT and AP Rounds?
Squash rounds, or high-explosive anti-tank (HEAT) rounds, are designed to penetrate enemy armor. They differ from armor-piercing (AP) rounds, which use kinetic energy to pierce armor. However, despite their shared purpose of penetrating armor, squash rounds cannot be fin-stabilized like HEAT and AP rounds due to their specific design and operating mechanism.
HEAT rounds have a hollow nose filled with an explosive charge. Upon impact, the explosive creates a focused jet of molten metal that penetrates the armor, destroying it from the inside. Fin stabilization is used to ensure the HEAT round impacts the armor at a perpendicular angle, maximizing its penetration effectiveness.
AP rounds, on the other hand, are solid projectiles that rely on their high kinetic energy to penetrate armor. Fin stabilization helps stabilize the AP round during flight, ensuring accuracy and preventing it from tumbling or deviating from its trajectory.
In contrast, squash rounds have a unique design that precludes fin stabilization. They consist of a solid, heavy metal core covered in a thin layer of explosive. When they impact the target, they flatten and "squash" against the surface, creating a great amount of pressure that penetrates the armor.
The key difference between squash rounds and HEAT or AP rounds is that squash rounds must impact the target at a shallow angle to maximize their penetration effect. Fin stabilization would interfere with this, disrupting the squashing process and reducing their effectiveness.
