Heuhen, do you have any sources that can confirm that the FNAN-class will get 40MM? Also, your typos are embarrasing. It's "Fridtjof Nansen" and "Thor Heyerdahl". Please, for your own personal and our national pride's sake, get it right!
I typed the name correctly except the one place in my text. The headline on this page I have not written but it did Golly ...
when it comes to the 40mm, so I went to check around a bit, and it appears that military is a little secret of such things so I will remove it for now. But she will get in a 40mm Bofors gun CIWS Mk.3 on the hangar in the future.
The closest I can be specific of about this (without getting the military on my neck!!) is in from the "milforum":

Found this here, so now I can do it perfectly!
