You can't credit, for just changing: gun's, missiles. etc. parts can't be credited.
on foredeck you have an MK-48/56 mod 2 VLS it can carry only ESSM and not the Standard missile. And I don't think this hull can carrya a MK-48/56 mod 2 VLS.
Norwegian Navy will never let any country build the same frigate as Norway. for Norway it will be the same as declaring war... on them. Norway would also never sell something that advance ship to a country as Columbia. The it comes to USA, I don't think they will sell SPY-1 radar to every one that have money to pay for it.
And at the end, when borrowing a drawing it's polite to ask first!
the rule for use a large part as the entire hull you just use here is also need credit. BTW this frigate hull will never fit a vessel like that, and it show a person that is lazy.
you have on the last drawing put railings and life-raft up on other railings, thus give you 1,5 meter high railing. Almost every thing of the ship is ..... I let some one else tell you, I am going to bed before I going really Norwegian/viking mad on this.
