Errr...

Exactly what energy do you think HEAT deliver? Magic? The difference between an APFSDS and a HEAT jet is where the energy is created (gun barrel as opposed to from the round itself) and how the penetrator is composed (solid preformed as opposed to liquid jet formed by the warhead detonating), not what kind of energy it delivers into the target.


As far as I've gathered the EFP's designed for AT work differs from a HEAT jet in it creating a bigger chubbier slug travelling slower. By being slower it also cools down and harden in flight.

Faster EFP's have been designed for other uses though.

This all makes it harder to disrupt with ERA (the bigger solid mass is harder to disperse than a smaller, thinner stream of liquid metal), and its slower velocity lessens friction during penetration, making composite armour matrices designed to take advantage of that increased sensitivity against friction lack their increased efficiency against EFP.

Another effect from having the larger penetrator "slug" is that it doesn't loose focus as fast, and therefore can be set off at a greater distance from the target. Spaced armour may also become less effective than against HEAT.
