It's the mid-90ies so NLOS isn't in play yet and the Mk 41 just plain don't fit. He has enough helicopters to ruin anyone's day so short ranged SSMs wouldn't be of much utility.
Whether to use the the 127mm or the 8" is a matter of priorities. The 127 is lighter, has a higher burst ROF and, assuming the same volume is used for magazine in both cases, a lot more ammunition.
The 8" gun has longer range and more bang per round. At this point Vulcano is still a paper dream.
