Could later Type 42 batches arrive before the Falklands?

Could Batch 2 and Batch 3 Type 42 destroyers be brought forward so more were ready for the Falklands War?

Some acceleration looks plausible, especially around the ships completing in 1982; adding Sea Wolf alongside Sea Dart is a separate early design opportunity.

The question proposes bringing later Type 42 batches forward. The answer first considers Batch 2 easier to accelerate, with more doubt about Batch 3. Checking individual ships complicates the premise: Exeter and Southampton were already commissioned before the war, while Liverpool is dated to 12 May 1982 and Nottingham to December. Manchester's November 1982 commissioning makes an earlier arrival worth considering, while other Batch 3 ships are placed in 1985. Planning from the beginning of the program also offers a design change: fit Sea Wolf alongside Sea Dart. Earlier delivery and additional close-range defence are therefore separate improvements within the counterfactual.
