The Royal Navy's Type 45 Daring destroyers are VERY capable multi-role anti-air destroyers with capabilities close to equal to any Burke destroyer...their missiles lack the range of the really Long Range standards, and their magazine is smaller (48 missiles) but other than that...they are very capable and strong.
In addition, they have been integrated into the US Navy's CSG defense program:
Their Astute SSNs are on par with our Virginia class too.
Problem is, they only have about sixe of each.
Probably enough to provide two Type 45s and one Astute for any one of their carriers deployed.
"Problem is, they only have about sixe of each. "
Thus my comment about sufficient assets.
They have good tech, good history and knowledge...but no ship building program to speak of.
Truly sad given their history.
