With B&T in Norway you had better abandon the article convoys or escort them with heavy ships capable of slugging it out with B&T.Now if I was admiral I would put all three KGV at the Home Fleet with Rodney and battlecruisers HMS Hood and HMS Tiger. For Force H would be HMS Renown and Malaya which by this time her speed would be 23 knots after the refit received in USA. HMS Nelson would be sent to Alexandria which Barham would have been sunk and Queen Elizabeth and Valiant out of commission. HMS Repulse with all 4 R battleship would operate in the Indian Ocean while waiting for Warspite to arrive in January.
In this role there isn't really a huge difference between the KGVS and the R class B&T since B&T will come looking for the ships being escorted.
