How long would the reconstructions have taken?
Mostly because Vanguard didn't work well as proof of concept. The whole idea was, that by using guns, turrets and (partially, at least) armor from old R-class, Vanguards could be build much faster than from scratches.Of course nothing came of either the Australian fantasy or of junking Rs to get more Vanguards, because by the time that might have happened there were rather more urgent concerns.
In 1939 the full up reconstruction (new machinery) was expected by the Admiralty to take 3 years starting around the beginning of 1942. The reduced version probably 18 months.I would say, depending on the extent of the rebuild, anywhere from 12 to 24 months.
From as early as 1931 the Admiralty planned to replace the R class before the QEs. The initial plan was as follows in terms of scrapping the old ships:-Also note that the Admirality thought in replacement classes since Pre WW1. The KGV's were considered as replacements to the QE's Lions as the Revenges and a new class might had been the Nelson replacements but not the Vanguard as stated it was a mobilization BB. I do not know how the Renowns and Hood were to be replaced.
The estimated time saving in 1939 from recycling the 15” turrets was also not that great- 36 months for a Vanguard v 42 for a 16” gunned Lion.

It should be noted, that while turrets taken from light battlecruisers required extensive rebuilds - like replacing their relatively thin armor plates - turrets, taken from R-class battleships required only limited refit (like increasing the max angle).
In 1939 there are another 4 15” turrets around. From WW1 era monitors Terror & Erebus. Also the turret training ship Marshall Soult (turret went to the new monitor Roberts in 1941). The final turret was in storage, having been built as one of the pair for Furious as an alternative to the 18” mounts (it went to the new monitor Abercrombie in 1942)."Battleship (turrets) recycling" - only the British could invent such things. Turning R-class into Vanguards to get more, good battleships faster.
5 R-class with 4 turrets each is 20 turrets.
While it would be logical to build 5 Vanguards with 4 turrets each;
- one should note that, had the RN been desperate to get one more battleship hull in the water, they could also build 6 ships:
- 4*3-turrets, 12 turrets (= Renown BC, 6 guns)
- 2*4-turrets, 8 turrets (= Vanguard, 8 guns)
Hell of an idea, on paper at least. In practice... didn't worked well, as brilliantly explained above.
Imagine if the USN had done that with the Colorado class !
Their plans seemed to shift around a bit in the years before WW2.From as early as 1931 the Admiralty planned to replace the R class before the QEs. The initial plan was as follows in terms of scrapping the old ships:-Also note that the Admirality thought in replacement classes since Pre WW1.

1940 - 2 R
1941 - 2 R
1942 - 1 R & 1 QE
1943 - 2 QE
1944 - 1 QE & Repulse
1945 - 1 QE & Renown
1946 - Hood
1947 - Rodney
1948 - Nelson
An alternative plan had one ship scrapped each year from 1940 starting with the Rs, with the last QE in 1949. Then Renown & Repulse in 1950/51, Hood in 1952 and the Nelrods in 1953/54.
The alternative plan would only have worked if more ships had been given major reconstructions. For example Repulse’s engines were expected to last until 1943/4. They were not replaced in her 1934/36 “large repair”.
After modernisation the lives of the various ships were expected to be
Warspite - 9 years (to 1946)
Valiant - 6 years (to 1945/46)
QE - 7 years (to 1946/47)
Renown - 8 years (1948)
A full reconstruction of Hood between 1942 and 1945 was expected to see her life extended by about 10 years, otherwise she would only last until 1948-50.
The Admiralty plan in 1935 (never formally approved but generally worked to as far as possible in the late 1930s) called for the following BB to be part of the Buliding Programmes each year from 1936-1944:- 2,3,2,3,2,2,2,1,1. The long term aim was to achieve a strength of 20 capital ships.
The actual orders and plans were:
1936 2xKGV
1937 3xKGV
1938 2xLion
1939 2xLion
1940 2xLion (“firm proposals”) + 1x new 15” gunned battleship (which became Vanguard)
Then war broke out and everything changes so we have no idea what might have happened beyond the Lions.
Any 15” BB beyond Vanguard were pure speculation, and certainly didn’t have the support of Sir Stanley Goodall, the Director of Naval Construction, who considered them extravagant for the armament carried. The estimated time saving in 1939 from recycling the 15” turrets was also not that great- 36 months for a Vanguard v 42 for a 16” gunned Lion.
I know that the notion of 'additional' Vanguards crops up from time-to-time, but do you have/know the source material for the Admiralties plans?You might want to know that the Admiralty did plan to build more Vanguards, using twin 15s from the R class, which were to have been scrapped, having been subject to only the most minimal improvements in the 1930s. In 1939-40 the Admiralty was much concerned over the possibility that the Japanese were building new battleships (but hadn't the slightest idea of what was involved), and it saw the Vanguards as the least painful way of augmenting the fleet in the East. For a time, for example, there was hope (in the Admiralty) that Australia would pay for or operate Vanguard herself. This was 1940-41, and you can find a hint of Australian interest in a battleship in the Australian official history. Of course nothing came of either the Australian fantasy or of junking Rs to get more Vanguards, because by the time that might have happened there were rather more urgent concerns.
On Hood, she was considered the first true fast battleship, and as such revolutionary, although some might see much the same thing in the German battlecruisers. What happened to her was extraordinary, as it appears that the fatal shell hit roughly lengthwise, where she -- and the QEs and Rs -- was poorly protected. It also seems to have had a rather long fuze delay, which was why it exploded in just the wrong place. After the action, there was an emergency analysis of the vulnerability of existing British ships, pointing up the transverse vulnerability of the QEs and Rs -- I do not remember for sure whether that also applied to the Nelsons.
On Australia, I doubt anyone in 1921-22 would have accepted that the Commonwealth was not integral with the British. I think there was even a legal link which made that clear. Nor were the Australians likely to have paid up to operate something that expensive. They found it difficult to finance their post-WW I navy for quite some time, despite their fear of the Japanese.
It surprises me that no one pointed out that, had work continued on the three other Hoods, they would have been in much the same position as the Lexingtons in 1921 -- incomplete, expensive, proceeding slowly. Wouldn't the RN have tried converting two of them into carriers, given the carrier clause of the Washington Treaty? And wouldn't that have afforded the RN the experience of running really large carriers like those the USN and the IJN used to learn what big carriers could do? They would have been a whole lot more survivable than Courageous and Glorious.
This is highly unlikely post mid 1940 for the repairs and rebuilds the Hood needed and the RN wanted. If it did happen the RN would have gotten the bare minimum, basically what the Hood need to fight and nothing fancy like the 5.25s.possibly in the States
To my knowledge only the Nelsons were considered for Modernization in the US after WW2 started and the USN declined becuse their 5" turret/gun production capacity and dockyards were already quite stretched.
Not that interesting, more of a go figures there.It is also interesting to note that the USN continued to refit its old battleships in this period. West Virginia didn't complete her rebuild until July 1944. And Arkansas, New York and Texas were all sent to the Pacific in late 1944/early 1945 being given such repairs as necessary.
