The Kidd class was in fact far more potent a warship than appearances would give it credit for. We took the design of our previous destroyer class, sold it to Iran... wait, they just torched our embassy... uh, we billed Iran for it, then brought it up to speed and made it as good a warship as possible, even comparable to Ticonderoga class Cruisers.
To make a comparison there, I'd say the 45 is definately ahead of the Kidds. Unfortunately, given all this talk of "fitted for but not with", I
get the idea that either the admiralty or the MoD have completely forgotten the most important lessons they learned at a high price in the south
Atlantic in 1982. Namely, It doesn't matter how good your high altitude/long range weapons systems are, if you skimp on the close in lowlevel
defences, you WILL loose ships and lives.
