Another piece of equipment that IMO deserves a second look, is the TOW-2B. (understand that this patch is nearly out the door, so certainly not expecting anything to happen this time around, if at all. Then again, never "Expect" anything, as we are owed nothing
)
As is, the TOW-2B's 100 "pen" is, I assume, from many sources lumping it and the TOW-2A together, and then listing a penetration value (typically 800 or 1000-1025mm RHA)
This is correct for the TOW-2A, and it's HEAT warhead. However, the TOW-2B does not have a HEAT warhead, but uses dual (E)xplosive (F)ormed (P)enetrators. (In essence KEPs produced from the initial explosion)
Now, in 2 like sized warheads (warhead diameter and thus cone liner diameter for HEAT, dish for EFPs) the EFP is going to have a significantly lesser penetration, but can achieve it at a variable standoff distance, whereas a given HEAT warhead has an ideal standoff detonation distance, anything more or less will reduce capability.
The TOW-2B's warheads (2 offset to increase hit/kill chance) are ~1" smaller, @ 5".
Now finding an exact penetration value is like finding unicorn teeth. However, the physics involved are pretty straightforward (Comparing the principal factors of HEAT penetration to those of Kinetic penetration.) and tell the overall tale.
One set of guesstimates (The SB Pro PE developers and their sources) have it at 350mm RHA. Now as to how accurate that figure is, impossible to say. It is no doubt closer than 1,000mm.
