Lethal failure = a succesful hit to the simulation engine, in other words, you can expect a conventional hit and an lethal over-penetration to look identical inside CMANO, which IMO is already happening.
I was talking about the detonation effect, calculated to DP bonus in CMANO. I also know a tomahawk with more remaining fuel in it could cause bigger damage than lesser because of the FAE, but only works when achieved adequate penetration.
OP however is indicate the missile warhead goes off too late, or even a dud, that the remaining kinetic energy will go through the ship hull, the shorter of the cutout width, the more likely to cause OP. The target will not receive DP bonus when warhead explode outside the ship, unless it's a fixed, land-based unit that being bombarded vertically, since ground cannot be overpenetrated.
Here's the example, see how much the detonated force of energy escaped from the other side. If they are all inside the ship, it'll rain a shower of steel already:
