What should the Royal Navy have changed after the Falklands War?

After the Falklands War, which Royal Navy decisions should have been retained or expanded, and what should have been replaced?

Replace outdated ships with modern Type 22 and Type 23 frigates, consider the preferred Type 43 alternative, and preserve the ability to fight wars beyond the central NATO scenario.

The Leander-class frigates had been successful mass-produced ships in their own period, but their capabilities no longer suited the tasks imposed on them in the Falklands War. Fleet recapitalization brought Type 23s and increased Type 22 numbers. A Type 43 would have been a preferred addition, though the actual fleet received longer Type 42s. Naval cuts had continued under successive governments because Cold War planning prioritized NATO's central front. Michael Clapp recalled being discouraged from practising convoy operations on the grounds that a nuclear war would end before a convoy arrived. That assumption left other kinds of war outside the dominant planning model.
