Possible but theirs little to truly suggest that this is the case, source material mention them to be HEAP and the novels often mention a DU component. About the only worse thing than a water melon would be a sphere and a flat plate. Giant water melons, meanwhile, are goofy aerodynamically, ballistically, and in terms of armor penetration. They've figured out the perfect way to put a maximum amount of kinetic energy into a minimum impact area: long rod penetrators and shaped charge jets. Modern munition designers aren't blithering idiots. But to maximize mass with a minimum of impact area, you need density (more mass per volume) and length (more mass behind the impact area.) The longer the dart, the more energy to power through the hole. You can't do much about the velocity by shaping the projectile (other than aerodynamic drag: darts rule, eggs drool). The amount of kinetic energy contained by a projectile is equal to 0.5 x mass x velocity x velocity. Meanwhile, a longer projectile maximizes the amount of kinetic energy available. Basic freshman materials engineering: the bigger the hole, the more energy required to make it.Ī narrow projectile minimizes the amount of armor that has to be destroyed, and thus minimizes the energy required from the projectile.
A bigger, wider projectile has to contact more armor - that's bad. The armor and projectile engage in a game of mutually assured destruction at the places where they touch. No, long rod penetrators are perfect for penetration.
