![]() ![]() So theres the answer - both armour and armament technology is far more advanced nowadays - tanks can occasionally be defeated with RPG7 type rounds - but not often - they will almost always be defeated by modern Kinetic energy rounds but not likely those of the ww2 era, which despite being fired from a similar sized main guns have far less penetrating power. It is also made of much denser material than ww2 era shells - typically depleted uranium with an extremely hard tip. Hence the round is called APFSDS = Armour Piercing Fin Stabilised Discarding SabotĬompared to ww2 tanks the barrel itself is the usually longer and smoothbore (not rifled) - so it gets the full power of the larger caliber to drive it forward but less resistances. It is fired with a surrounding sleeve (sabot) that fills the barrel and discards upon exiting - leaving a thin, needle-like projectile travelling at extreme velocity that is subject to less deceleration than a larger shell as it travels towards it's target, and it's fight is stabilised with fins. The shell that is fired from a modern tank is much smaller in diameter than a ww2 shell but is fired from a barrel that is as large or larger - and this gives it a higher velocity. ![]() KE rounds rely on pure energy (mass and velocity) to punch through armour like a bullet. So now the most effective round against modern tanks is, once again, the Kinetic Energy round, but they have come on a long way since ww2. ![]() This new armour is very effective against HEAT projectiles - but not inflable, and occasionally will be defeated if hit in certain places. Until the advent of Modern tank composite armour such as the chobham derivitive on the M1 Abrams it became the most effective anti tank round. Rpg 7 is a shaped explosive charge (High Explosive Anti Tank or HEAT) that differs in principle from a Kinetic Energy round similar to those fired by ww2 tanks. ![]()
