take a look at my last comment.....
and ... AIM-7 AND ESSM????
I realize that there may appear to be some redundancy in this, but as others have said, when life gives you lemons, you can still use the slightly older lemons you already have to make a lot more lemonade. Replace a couple cells with the quad packs for the ESSM and you have twice as many SAM's as you would have with just the regular Sparrow. Plus, as this nation lacks a dedicated AAW destroyer (at the moment?) having the longer range ESSM provides a medium-range anti-air capability.
Had forgotten about replacing the parts with the newer versions on the forum, so below is the modified Cabot with the up-to-date parts. May do the same for the St. John's, et al.
Cabot with an updated 76 mm compact and updated Goalkeeper. Even though I love me them navy ships, I can't help but giggle over the pink and green roundel on the Cormorant. Never mess with a country that has pink in it's flag and symbolism, tough beyond measure.
Shall post in a bit with an updated St. John's, but am fooling around with a DDG and some older designs to show the history of this 'what-if' flotilla.
