I don't really understand what you want
?
And of course, there's Repulse, even more deserving of a Renown-style rebuild
She will always be worse than Repulse or (Hood!) so that puts a top limit on cost of rebuild.
Nothing here so far has made keeping Tiger over Iron Duke worthwhile.
Iron Duke was effectively worthless in WW2 (she had nothing better than a R class, at least tiger has speed even if she is no better in any other way)
Make Tiger a valuable fleet unit or scrap her
With the limit set above she is never going to beat any real BB but she should be able to kill any 8inch and be a heavy fast escort for CV's etc, as Iron Duke was effectively worthless the opportunity cost of keeping her is not much ?
SO - my rebuild (although I would like one more like your pic) is realistically going to be cheap and dirty.
- new boilers for high speed (and to replace ones taken out by treaty, this is the biggest cost I think)
- 4 inch twins are cheap (and RN made lots) as are 20mm's
- limited directors etc
- only a limited plating in of the bridge/centre section and funnel (cheap can be done afloat at any yard (even civilian) no really heavy stuff to move like armour etc ).
Would this really cost to much to get a 4th BC (admittedly a week one but will kill any CA or Deutschland raider etc).
Thanks JSB
PS:
The twin 4" mountings are going to be decimated by muzzle blast as soon as the fore and main batteries fire athwartships
any worse than her older HA mounts ? (admittedly I have removed the casements, I'm thinking of leaving a few and or removing the centre rear most 4 inch (ie 4 of 5 from bow) as it will be worst affected.
Nothing has been done to improve her main armament fire control.
Cost ! not all QE's / R's got new directors (but will add some radar on)
Her HA fire control remains suspect.
Cost ! not all QE's / R's got new directors ? and is 2 HACS really that bad ? With ( 20 4 inch + 16 40mm + 16 20mm ) she's not a bad AA fit for 41?
