No Renown or Nelsons. No QE or Rs.
So just the KGVs or the ones still afloat. So pretty much the vanguard (if you pardon the pun) of the battleship fleet.
But a lot of carriers.
So yeah if I was looking into that the. Maybe I would be making a decision based on this.
To say a battleship can offer flak support is valid but a cruiser can also do that at a cheaper cost. And a monitor can do shore bombardment.
So yeah.
Shore bombardment only works when your winning. Against a peer opponent, rocking up to your enemy coast is a surefire way of a one way trip to the bottom of the sea.
R class - the end of 1943 saw 2 sent to reserve as they were worn out and the RN needed the crews to man more modern ships. Royal Sov refitted late 1943 in USA but still had problems so she went to the Soviets in May 1944 on loan until 1948. Ramilles used for bombardment purposes off Normandy and to reserve in 1945.
QE class - Warspite severely damaged by bomb and mine by late 1944 and not worth repairing. Malaya old, slow, poor machinery state, to reserve in Aug 1944. Valiant in the East Indies in 1944 supporting carrier operations until almost lost in Aug 1944 when the dry dock at Trincomalee collapsed with her in it. Under repair at end of war. QE spent most of 1944/45 in the East Indies incl support for carrier raids on Sumatra/Burma/Malaya. Replaced by Nelson in July 1945 when home to reserve.
Nelson class - Rodney was in a very poor material state by Sept 1944 after bombardment duty off Normandy and badly overdue for a reconstruction which she never got. Home Fleet flagship in 1944/45 but rarely left harbour. Nelson mined off Normandy and under refit until early 1945. Then to East Indies in time for the end of the war.
Renown - spent 1944 and early 1945 in the East Indies supporting carrier operations. Brought home in March 1945 in case of a last minute sortie by German Fleet (DoY and Anson were just completing refits at that point and needed to work up before heading for the Pacific so were not available for the role).
The use made of the KGVs in 1945 mirrors that of the 10 USN fast battleships supporting TF38/58. Look at the AA armament that a KGV, particularly the refitted DoY, Anson and Howe (from Sept 1945) can bring to the fight compared to a Town or Fiji class cruiser in terms of the number of director controlled multiple pom pom and bofors mounts, which is what really counted in dealing with the kamikaze menace.
DoY etc - 16x5.25, 8 octuple and 6 quad pom pom, 2 quad bofors plus many single and twin 20mm and single 40mm. KGV lacked the extra 6 quad pom pom.
Belfast - 8x4", 6 quad pom pom, plus single and twin 20mm and single pom pom and bofors.
Most of the other cruisers in the BPF in Aug could only bring 3, 4 or 5 quad pom pom / quad bofors depending on ships concerned to the party. And the RN was not exactly swimming in modern cruisers with heavy AA armament by 1945.
You will find full details of the ships forming the BPF and EIF in August 1945 here.
But remember both fleets were building in strength as 1945 went on and as ships could be released from service in Home waters to be refitted and sent East. So those lists are not what was present in theatre at the start of the year, nor do they represent the further expansion that was planned. In the case of the BPF that build up was restricted by how quickly the Fleet Train could be built up to support them. Admiral King of the USN was adamant that the BPF should be self supporting. In practice those in command in the Pacific were prepared to be a bit more flexible.
