first of all, some pointers.
the midship GMLS is not going to fit. that is for certain.
the aft GMLS might fit, but only just.
the Mk 13 was drawn without the missiles on it because quite a few missiles are oversized on the parts sheets for detailing. I would ask you to not add them on, because that results in some horrible problems with scaling etc.
I would suggest replacing the Mk 13's with guns. guns are for quite a few targets still attractive, and not many ships have been build without them.
an Mk 10 GMLS can fire ASROC as well. if you have that on board, you might leave the Mk 112 off.
also, if you cannot fix the photobucket settings, would you maybe try another image host? I use the public folder of dropbox, but others use imageshack, majhost, for example. I have some more comments but with the picture being resized I cannot really look into them that much.
Ok I will fix the image host quickly so you can look at the ship more closely before I continue on.
Also what type of guns should I replace the Mk.13's with?
