some parts might be outdated, but I think these are all real life CIWS systems. I might miss some missile CIWS though......
one note: I have left out all neverbuild weapons, and I would suggest to make an separate sheet for those.
I have not sorted it all perfectly out, so gollevainen, there is still some work to be done on this one..... but most is done IMHO.
the sheet with the guns all sorted out is coming too, but on that one I am really not sure if I have all, because my knowledge of US, french, russian and british guns is not enough.
