Ah, good, deck penetration; this might save us from barmy kitbashing.
What if it fits with just minor modifications? Thats not barmy.
ok, so maybe it is.
But, seriously now... showing the deck penetration required for various guns and missile systems is not necessarily a bad idea, especially for those of us who don't know every weapons system in excruciating detail. It needn't be super detailed, perhaps just a dotted line or some such showing how many decks down something goes since the below decks bits ain't shown anyhow. It would save alot of embarrasment and redrawing. Not everybody has the same resources. I know several times I have tried looking something up and maybe didn't put in the correct parameters or something for the search, then ask here and a number of folks will have what was being searched for.
