But the navy was literally 3 times as large then. After these cuts, the British navy will be 1/6th the size it was in 1980. Meanwhile, British GDP per capita has risen 4 fold over the same period. They are vastly better off, the government takes 43% of the national income, and delivers bumpkiss for it. Just handouts, that is all they can even think of paying for anymore.
Even with the cuts, the UK has two available carriers, three available amphibious assault vessels (One Ocean and two Albions...all very capable), thirteen Type 23 FFGs, four Type 22 FFGS, eight Type 42 area air defence destroyers, nine nuclear attack submarines.]
I would expect their task force to consist of both carriers, all the amphibious vessels (which could carry 2200 Royal Marines), four Type 23 FFGs, two Type 22 FFGs, four Type 42 DDGs and at least two, if not four of their SSNs.
That's a potent force...but as I said, would need to be augmented by a US Nimitz carrier for fleet air to ward off the SU-30s.
Now, there are already two Daring Class very effective PAAMS area air defense DDGs floated, one of which is in sea trials. Either of those would also make a very effective addition to this task force, on the order of the capability of a Burke DDG,
