As with all Striker Cruiser proposals the MK I was never built, however if it was it almost certainly would had undergone modernization by the 80s-90s. These might include:
Replacement of MK 26 launchers with 122-183 VLS
Tomahawk in MK 143 ABLs mid-ship
Note that this would probably had gave the cruiser more long range firepower than the Iowa class BBs modernized in the 80s.
