The only thing the shorter version buys you is a better Helo hanger. Virginia herself wasn't laid down until 1972, so any ship prior to that would be working with older electronics not newer. I say go back to the long version, and keep in mind the CSGN designs.
What do you mean with ''older electronics not newer'' i think you mean the SH-60 Seahawk helicopter? maybe its better to use the SH-2 Sea Sprite
Oh I was referring to internal electronics, not visible ones. A proto-CSGN is a sticky widget, because (as I understand it) a lot of the work done on a CSGN includes AEGIS, and the prior designs were based around the Typhon system. I don't really see the US building any large cruisers without either system in the late 1960s and early 1970s.
The long range air defense systems go from SCANFAR (SPS-32/33 on
Enterprise and
Long Beach) to Typhon (only deployed on
Norton Sound and would have used the large SPG-59) to the AEGIS Combat system (with SPY-1 Radars).
This ship falls into that ugly gap between Typhon and AEGIS.
