I remember reading in AVWEEK a couple years ago about a program to develop a supersonic SSM but it was intended for ground rather than sea surface targets. Perhaps SM-6 will have that capability while the new 5inch62 was mentioned of having the potential for antiship rounds while the 155mm/52 caliber AGS could have an antishipping round also. I would like to see the IR homing AA shell revived for both guns for if there is anything needed it is all the ASMD one can afford. Harpoon might be mounted in canisters forward of the bridge perhaps on a platform if stability margins were availible which I doubt but if the remaining below decks magazine retained for stability was removed and replaced with ballast that might be possible;ballast weight would have to be less than magazine weight yet be enough to maintain stability while allowing increased growth margin. Proceedings magazine suggested mounting MK 45 gun in place of missile magazine.

I think what we are going to see in the next generation of systems is the complete blurring of the lines between what is an anti-ship missile, land attack missile, anti-aircraft missile etc. Already those lines are getting a bit fuzzy.
