Best British interwar fleet?

A factor I think of being designed for the war the Royal Navy thought they were going to fight verses the war they actually fought. American carriers were focused on the Pacific almost from the start leading to their decision to go with larger air groups and things like wooden flight deck to maximize hanger height and permanent deck parks. Had the UK been focused on fighting a naval war in the Pacific, we might have seen them make very different design choices
RN in the mid war years had significantly greater bases and logistics than wartime USN did.
 
Navies were starting to become sensitive to maintenance costs and the costs of different types of warships. The graph below shows 1920-30's RN figures for total warship cost of ownership or the cost of the capability over a 26 year period with costs of construction and maintenance per ton. This factors in the annual maintenance, crew pay, consumable stores like food, ammo and fuel, regular refits and a 'large repair'. It excludes pensions and depreciation.

As you can see, the costs of a 'submarine' capability or 'destroyers' was significantly higher than 'battleships'. Carriers had an airwing that was replaced every 5 or so years. BC were slightly more expensive to run as they burned more fuel at higher speeds. Carriers also ran at speed to conduct air operations. Destroyers and Submarines were more expensive because they only had 16 and 13 year lives respectively so over the 26 year lifespan of a battleship, they are replaced twice.

Below the graph is a nominal exchange for an 8 Ship Battle Squadron, ie 8 BB vs 7BC vs 3CV vs 6CVL etc. In the 20’s carriers were expensive untried auxiliaries.

Thanks for putting this up, it fascinating, and explains a lot. Its often said the WNT helped end the age of the Battleship, and accelerate the development of the more complex, and expensive Aircraft Carrier. This chart suggests BB's were the most cost effective warship you could have, by ton. If you can't afford a bunch of DD's, buy a BB? Sounds counter intuitive.

Let me try to understand this chart better. 8 BB's displace 280,000 tons, 33 DD"s 49,500. The BB's total cost is 5,507,600 Pounds. 33 DD's 5,631,120. 13 CA's 5,656,300. 20 CL's 5,684,400. 42 SS's 5,667,984. 3 CV"s 5,860,170. 6 CVL's 5,622,000. So all these ship type squadrons are equal in cost.

It seems these calculations determined the Treaty Terms. The USN, and RN put most of their tonnage into Battleships, 525,000 vs. 180,000 for CA's. So the RN may have wanted 20 more CL's, but it would've cost them half has much as the Battle line. So this was the balance in the interwar period, till the build up for WWII shifted everthing.

Wow, thanks for this. Im very interested on cost effectiveness of naval ships.

Would USA and the rest of the world be aware of this cost effectiveness for Battleships by 1915 or 1916? Or would this require the data from 1920-30 from the British to assume that Battleship and Battlecruiser are more cost effective for a 26 year period?
 
18" guns in the early 20s are something of a Pandora's Box- once it's opened, it can't be closed, but opening it leaves everyone worse off. An 18" armed ship needs to be utterly massive. The difference between the weight of shells fired by the British 15" and contemporary 16" guns wasn't all that much- the BL Mk. I 15" shell weight was only a couple hundred pounds less than the American 16" Mk. 1 and 2 and Japanese 41cm 3rd Year Type- 1920 lbs vs 2110 and 2200 respectively. The difference between those and the proposed 18" guns was massive. The USN's would have fired a 2900 lb shell, the Japanese 46cm/L50 a 3000 lb shell, and the British 18"s a 3320 lb shell (the new 18 for the N3s would have fired a 2980lb shell at higher velocity)- and the Americans proposed a superheavy 3850 lb AP shell and the Brits a 4000 lb HE shell.

The only country that can really afford to start building 18" behemoths is the USA, and during testing, they found their 18" gun to be a great disappointment- excessive barrel wear, slow rate of fire and penetration not a significant improvement over the 16" Mk. 2.

It would be interesting to see what the USN would do with Tillman's Maximum Battleship designs as well. I don't think the 6-gun turrets would be realistic, but a faster ship with 16" triples would be quite doable.

Your right, Battleships had reached the practical limit of their size. The Yamoto's were the end of the line. The WNT stopped everyone from getting there 20 years earlier. 4,000 lb. shells? With over 30 ft drafts how many ports can they use? there's a kind of egomania to these designs, like a later age building 50,000 nuclear warheads, it's beyond all reason. The military mind sometimes has a narrow view.

Interesting how the numbers are twisted - willingly or not - against submarines and destroyers. V&W soldiered on for 30 years, WW I subs were used in secondary theaters almost till end of the WWII, WWI cruisers could have been used - if there was need - till end of the WWII usefully etc.

Is the reserve / active status also thought about? During WWII it was easier to man smaller vessels out of reserve or mobilized personnel, so more smaller vessels could have been feasibly put into reserve status to be mobilized in wartime.

Most navies had worked up costs pre WW1. The German Naval Laws stipulated age limits for ships.

These are peace time figures for full active service. Reserve status seemed to range but 40% of the cost of full commission seems to be a usual figure. I’ve also seen ‘laid up’ as 10%.

An advantage of battleships was that armour does not require maintenance. The problem with submarines is their limited lifespan in a peacetime environment.
 
The RN had bases all over the world, bar the middle of the Pacific. Nowhere was more than a few days sailing away from a source of fuel and supplies. The USN had bases in the US, Hawaii and the Philippines. If they wanted to go anywhere and fight they had to take their fuel and supplies with them, or rely on RN bases. The RN gets a lot of flak over the lack of a proper fleet train but the fact is until the formation of the British Pacific Fleet they didn't really need one.
 
Meant to chime in on these earlier, but better late than never!

So what you're saying is the fast wing role was put on the QEs and the battlecruisers relegated to cruiser leaders. So the new battlecruiser roles are raider hunting and leading cruisers squadrons. Fast forward that 10 years. G3s are the fast van, what's going to be the cruiser killers and cruiser leaders. Hood, R&R?

The QEs were originally intended to follow what was the RN's normal shipbuilding programme during the 1906-1914 years, which was typically 3-4 battleships and 1 battlecruiser per year. FWIW, the very first battlecruiser, HMS Invincible, was a 25kn ship. The QEs were originally supposed to be configured like the preceding Iron Duke, class, but it was found that 8× 15" guns throw a heavier broadside than the 10 13.5" guns mounted by the Iron Dukes. By using all oil firing boilers instead of mixed firing, the QEs could get up to a theoretical 25kn. It was thus decided they could form a fast battleship wing, and the battlecruiser was dropped from the 1913 programme and a 4th battleahip was ordered in lieu, and a 5th when the Federated Malay States offered to fund it.

In practice, the QEs did not succeed in their lofty goals. They were overweight and had blocky battleship hull forms, and could only make 23.5-24 of the 25 intended knots. Battlecruisers also got faster, going from 25 kn to 28, 30 and 32 kn ships, so they could not keep up and were thus tied to the slow battle line. After WWI, it was affirmed that an intermediate speed between battlecruisers and slow battleships was of little to no additional usefulness, as if they were to give chase, they would leave the battle line behind, but were not fast enough to operate with true battlecruisers.

However, they proved that all-oil firing and fewer but bigger guns are very useful, and although it wasn't possible in 1913, that a true battleship with battlecruiser speed could eventually be possible- the QEs, after all, were mightier than Dreadnought or any Dreadnought built before her, and nearly as fast as Invincible.

The Alaskas are a bad example of super cruisers for a few reasons. Call up CalBear and he'll find several more..
But at the end of the day the ships they were designed to go kill just didn't do what was expected. The Japanese didn't go for commerce raiding in the sense Germany did in ww2. They also lacked flagship abilities. They were the size of the Scharnhorsts.

To me at least, the Alaskas were not awful ships. They were very good super cruisers. They were faster than almost anything afloat bigger than a destroyer. Their 12" guns were far superior to the USN 14"/L45 and delivered comparable belt penetration and superior deck penetration vis the USN 14"/L50 in a lighter package with a faster rate of fire. Their topside protection was excellent, as was their radar and AA suites. There are, however, two huge flaws to me.

The first is that they only had cruiser style underwater protection with compartmentization; no liquid-void system or torpedo belt. That would leave them one fish wonders, especially if hit with a Long Lance. At 808' long, they were longer than any USN battleship bar the Iowas, and 80' longer than the next longest, the North Carolinas. That leaves a battleship sized target with cruiser protection.

The second was the cost. Their gun system, made from scratch, was the most expensive in the USN, more expensive than the 16" L/50 Mk. 7 on the Iowas. In fact, an Alaska cost 2/3 - 3/4 as much as an Iowa but were not 3/4 as capable. It would have been a much better investment to complete Illinois and Kentucky rather than Alaska and Guam

The Lexingtons were the definition of a glass jaw. The Americans took exactly from jutland, said hey look none of the 9" armour belts got penetrated so clearly we should put a 9" belt on our battlecruisers. Nobody seemed to notice initially that hey all the german battlecruisers had 11 inch guns and every battlecruiser since has had 15" guns or higher surely we should armour against that instead? Which seemed to dawn on them later in construction.
In almost any fight with an enemy battlecruiser apart from the G3s it would be a case of who hits first.

The problem the Americans face in 1920 is that Britain and Japan have lots of big and fast ships and the USN has none. The Standards, while very well armed and armoured, were 21 kn ships with stubby hull forms, so no more speed could be coaxed out of them without huge reconstructions. The USN has nothing capable of counter-scouting, and a CA stands no chance against a Kongo or Renown, let alone Hood, Amagi or G3, nor do they have anything that could chase off a fast squadron attempting to harass the battle line and run. In these early days, something is better than nothing, before a "Sims Doctrine" (Compromise on nothing but displacement) fast BB is built.

Again, same problem the Brits run into: the Japanese only have six battlecruisers (the last two Amagis are unlikely to be completed as battlecruisers) and the Americans were seriously considering thirty 8" cruisers. And while the Japanese don't have the trade protection issues the Brits have, they were very interested in counter-scouting and breaking through American cruiser screens. The former is what led to the Furutakas to outfight the Omahas, and the Japanese aren't simply going to stand pat on that front with 8" cruisers being cranked out; the latter is what their CAs were actually supposed to do in their Kantai Kessen plan.

Compounding the issue is that the Japanese were very fond of using battlecruisers as a fast wing of the battle fleet. While the Kongos would probably be used in distant action, the Amagis are going to be tied to the battle fleet and thus held back.

The problem here is that Japan can't afford to have a large buildout of heavy cruisers and battlecruisers; there isn't enough Yen for both. Money makes it pretty much an either-or choice. I could see a few heavy cruisers, but in an unrestricted environment, the battlecruisers will ultimately be more useful in overpowering enemy scouts and breaking through screens. The IJN is worse off building CAs in a less restricted environment, let alone an unrestricted one, as their 4-8 bigger heavy cruisers still can't beat 30 USN ships, or even 20 if the USN keeps some in the Atlantic.

Is it just me or is this a truly bizarre metric? It’s like evaluating cost per kilo of hammers, screwdrivers, wrenches and drills to determine whether you should have four hammers and eight screwdrivers in your toolbox rather than one hammer, three screwdrivers, two wrenches and a drill.

Respectfully your not talking about the S/A War your talking about a later tactical confrontation, and the personalities involved. The British diplomatically supported the U.S.. The Boer War had nothing to do with American, or British Racism, the Boers are white. Britain found it's self isolated in the Boer War with the Germans, French, Dutch, and Russians all siding with the Boers, and only the USA supporting the British, and their Commonwealth.

The problems with von Diederichs are during the Siege and Blockade of Manila. He is not the only blackhead present (The French are not helping either.).

The US supported the British in the South African War for a curious reason.

Venezuela Crisis of 1902-1903: Lessons For Today

A quid pro quo. You stay out of our backyard and we won't mess you up in yours. The Russians seriously need to learn that lesson.

Yes throughout the 19th Century the USA, and UK were on bad terms, sometimes coming close to war. The last time was 1895 over the Venezuelan Boundary Dispute. After that with most points of contention settled they found their economic interests, and cultural ties drawing them closer together. By the 1890s the USA had the worlds largest economy, and along with the British were coming to dominate global finance. The UK was heavily investing capital in the USA, further accelerating American growth. The Growth of Japan was financed by the UK, and USA. The Japanese war effort in the Russo/Japanese War was financed by the UK, and USA, in order to check Russian expansion in Asia.

The British were not happy about it. In the 1890s, they were like the US in the 1990s, eyeing new rivals (China) and trying to game the international table to stack the odds (East Asia Pivot). The Anglo Japanese alliance was one of those 1890s moves. The Americans were not happy either about that move or the Russians getting to big for themselves in east Asia, but they figured half of China was better than none of China. The American move was to let the Japanese play their hand and see if they could neutralize the Russians (Let's you and him fight and we'll kill the winner.). That happened. As for the British and the French? As early as 1896, Mahan knew they were finished in East Asia. The Anglo-Japanese alliance, the RN's retreat, and the pulling back of the MN at the same time sort of confirmed the trend.

In the post WWI period Britain was heavily in debt to the USA. The Federal Reserve was exporting dollars, and floating the worlds economy. London, and New York were managing global finance, with the British trying to restore the value of the Pound, and stay on a Gold Standard. The USA was the No1 oil exporter in the world, Middle East oil was only starting to come on line. The UK was incapable of financing a war with the USA, since it's chief source of credit was the USA. Canada would have been a strategic liability, in USA/UK War, do you think they would support a USA War at a Commonwealth Conference?

Nope; which makes the support of the Anglo-Japanese alliance an equally dumb move in the immediate pre-WW1 and post WW1 imperial conferences. Would the British not see the US aimed at Japan was the correct move? But no; we get "Defense Plan #1 and the McNaughton Line and the crazy Harding administration Warplan Red. To put it in a modern context, there were 2 1980s nations that should have been natural allies against a new rising power, but because of their previous near century long antipathy managed to lock themselves into a permanent state of stupid. That would be a Chat topic BTW.

Military planners assess threats on a hypothetical basis, built on narrow technical factors. "Gee what would happen if the British Home Fleet sailed over, and shelled New York City?" Admirals, and generals will fight anyone their ordered to fight, personal feeling aside. National leaders need to take a broader strategic view. Do you really think President Harding was worried that Britain, and Japan might join forces, and attack the USA? He never lost any sleep over it.

Since they had no fleet train and the USN can neutralize the only 2 bases available for that sortie fleet before it got that far, the question becomes, what surrender terms do the Americans impose? Wrong move=instant British naval defeat. They should not be that foolish (But the Singapore Bastion Defense and the "Through Ticket to Manila" and the "The Southern Road" indicates one cannot assume that professional militaries are smart all the time.)

In fact Harding (Charles Evans Hughes actually.) gamed the system. Defeat your enemies without battle.

Yes FDR wanted to break up the British Empire, as a trade block, to advance American economic interests, and because like most Americans he was anti imperialist. And yes personalities like Admiral King were Anglophobes. But that's not the basis to set foreign policy on. The AJA was no threat to the USA, and I think the American effort to break it up was very shortsighted. They could've had a conference to limit Naval Forces without junking the Alliance. Arms Control saves money, and promotes international stability by making threat assessments easier, there are fewer unknows. Britain was a stabilizing influence on Japan, cutting them lose made the world more unstable.

You crunch your pickles and drink the brine. The Americans have wanted to end the British empire ever since 1861. Also don't forget Roosevelt was DUTCH in ancestry.

Is there a reason you decided to pick up this fight a week after it seems to have ended, especially since it was derail to begin with?

Don't do this.

You can never have enough hammers. For Americans, hammers and screwdrivers are the same thing.
The Admiralty had to defend itself against Air Ministry claims that it could buy 1000 bombers for the cost of a battleship.

Mind you said 1000 bombers would be far more expensive to operate and man than a battleship. And said battleship would last a lot longer

This response from the IJN would be in line with their thinking on the purpose and role of those fast capital ships - to have a qualitative advantage and those Battlecruisers can deliver that.
