MBT LAW indeed seems to have too good penetration values now.
NLAW at FDF site states that the penetration is >500 mm (RHAe?) and net weight of explosively formed penetrator is 1.8 kg.
Comparing to RBS-56 Bill2 and it's 110mm (main) warhead the NLAW has smaller, 102mm warhead. Simple calculation with scaling gives that NLAW supposedly has 79.7% warhead size and/or effect. Assuming penetration of 100 cm for Bill2 (as in the Swedish OOB) we have 80 cm for NLAW.
Comparing to APILAS, that has a 1.5 kg warhead and 720 mm RHAe penetration and again simply scaling (although APILAS is older tech) gives 864 mm for NLAW.
In the end we have something that has heavier warhead than APILAS but probably smaller than Bill2. Current 100 HEAT pen might be a bit high, 85 could probably be closer as it is smaller detonator than the one in RBS-56B (Bill 2).
