Patreon 100: Stalin's 1930 London Treaty - the USSR joins the Naval Treaties at London

The counterfactual assumes the London conference survives Stalin's arrival and accommodates his security priorities and aggressive bargaining.

The Second Five-Year Plan supplies heavy-industry foundations for a fleet, but Soviet measures of success ignore quality control and human cost.

A larger treaty fleet could turn naval construction into an employment policy acceptable to trade-union allies despite Labour's reluctance to fund defence.

Soviet destroyers and Kirov-class cruisers demonstrate real design talent, even as purges and uneven industry undermine execution.

Possibly in part, but early Soviet naval cooperation would more likely lean on Italy because Stalin did not yet view Germany as a major naval power.

The most plausible trigger for Soviet attendance is a longer-lived rumor that Germany might join the 1930 conference.

It would gain influence over rules that already constrained Soviet planning and oppose a settlement that admitted Germany as a major Baltic naval power.

It could buy armor abroad, but Stalin would likely force domestic production, and foreign planners would still have to treat the ships as credible threats.

The F-15 and F-22 analogy shows how conservative threat estimates can produce deliberate capability overmatch.

A plausible treaty battleship uses Project 21's all-forward layout but trades its claimed 30 knots for armor and realistic displacement.

Not inevitably, but only because a northern battleship program would have to construct maintenance facilities that the historical Northern Fleet did not possess.

They would probably use licensed or copied foreign machinery, following the Italian and Yarrow-Normand pattern seen in the Kirov class.

Perhaps it would add urgency, but Britain already had the technology and chose its wartime standard mainly to simplify training and rapid fleet expansion.

The likely Soviet demand extrapolates later fleet plans into an opening bid no existing treaty power would accept unchanged.

The existing capital-ship, carrier, cruiser, destroyer, and submarine allocations show how difficult it would be to insert a sixth major navy.

Stalin refuses a French or Italian share, while Japan accepts Soviet parity in exchange for permission to build more ships before leaving the treaty system.

French reliance on British support makes it difficult to reject a treaty that gives the Soviet Union a larger allowance.

Not all at once or by 1936, but Stalin could force a slower multi-yard program whose treaty authorization would still shape every rival navy's planning.

The bargain could survive if enough influential Japanese groups valued three extra battleships and expected Soviet construction to remain slow.

No; Sweden could build its own coastal defenses, but it was not considered a major naval power requiring treaty membership.

Extra tonnage lets Britain add capital ships, retain and modernize older vessels, and combine Ark Royal's size with heavier carrier protection.

Yes, because Britain had limited direct Baltic interests and preferred treaty limits on Soviet construction to an uncontrolled arms race.

Cruiser submarines. Soviet entry would extend that provision to Moscow alongside the other major powers.

Probably only by a Nelson-like margin at first, because Soviet shipyard size and capacity would not support much larger hulls without major new infrastructure.

The timetable could survive if the naval program became a favored project whose staff were protected long enough to finish, though that outcome is uncertain.

It would probably purchase or copy British or American design work, most plausibly the lineage leading to Ark Royal or Yorktown.

Probably not during the initial expansion, because the older ships would be needed for training and retained until replacements entered service.

Stalinist control poses an institutional obstacle because carrier aircrews must search, coordinate, and attack with delegated authority.

The speed of doctrinal development remains uncertain. The navy would first need a carrier and a mission, most plausibly in the Pacific or Northern Fleet.

A stronger Soviet fleet could widen the Far Eastern conflict and give Japan a reason to intensify carrier operations and leave the treaty system.

The enlarged Soviet fleet remains basin-focused and may resemble the First World War U.S. Navy, concentrating scarce industry on battleships and destroyers.

No; 1930s Soviet amphibious capability was riverine and inshore, without the landing craft and aviation enablers of the later fleet.

The destination is left open. The fleet could remain in the Pacific, with cooperation alongside American forces offered as another possibility.

Land-based aviation and a carrier could develop together, with the carrier serving a defensive role.

Not necessarily; Moscow would have to expand a second Pacific base and its transport links, changing the infrastructure alongside the fleet.

Treaty prestige turns the fleet into a showcase program backed by forced labor, new bases, and rail expansion at the expense of other projects.

Most plausibly near Arkhangelsk for the Northern Fleet, because the Baltic and Black Sea already had facilities and Pacific sites could be expanded.

American requirements point toward an earlier North Carolina class, while Britain weighs 16-inch parity against a faster, better-balanced 15-inch ship.

With a larger treaty allowance, the U.S. Navy can repeat a full-size carrier design instead of building Wasp around the small tonnage left under the historical ceiling.

Misleading test results help explain the attraction of a new 15-inch gun for both fast battleships and upgrades to older ships.

Probably, but available infrastructure would determine the ships, and no specific program is supplied.

No; Japanese 16-inch ships would drive the United States directly to a 16-inch main battery.

Yes. King George V or another group of admiral names are both considered plausible.

Italy can modernize old battleships and start Littorio-type construction sooner, while France may build a larger fast Dunkerque alternative and real carrier force.

Additional cruisers and possibly modernized British battlecruisers could become available, depending on British construction choices and what receiving governments would fund.

Individual displacement limits and aggregate tonnage could be negotiated separately, allowing more smaller battleships within the same ceiling.

Japan uses its enlarged allowance to build three 16-inch battleships that test the armor, engines, and yards later needed for Yamato.

Larger carrier fleets encourage earlier doctrine, exercises, air groups, anti-aircraft weapons, and dual-purpose guns across the major navies.

Tsushima, Shikishima, and Asahi are plausible suggestions, while Mikasa's museum status makes reusing her name less likely.

A predictable building program could preserve shipyard employment and produce six large carriers by 1938 without the expense of a wartime surge.

A Soviet treaty fleet makes Deutschlands irrelevant and forces Germany to confront capital ships it lacks the yards, time, and money to answer.

Answering Soviet battleships with aircraft would require better torpedoes and resources diverted from other German programs.

Technically yes, but Hitler's prestige and preference for German-controlled designs make that solution very unlikely.

The March 2024 assessment connects Sweden's NATO membership with its arms-production capacity and possible renewed interest in Gripen.

The greater threat could push the Netherlands to build more warships, although the program is left unspecified.

A March 2024 proposal links Gripen's operating requirements with the possibility of Baltic air forces using Sweden as a fallback base.

Royal Navy torpedo trouble illustrates how a common mechanism can fail differently when launched from surface ships, aircraft, and submarines.

Two or three larger armored British carriers could bring a radically heavier air group to Taranto than the historical force.

A coastal foothold could provide facilities after annexation, but Italian opposition would complicate Anschluss and the naval effect would depend on the available infrastructure.

The enlarged treaty strengthens every major fleet except Germany's and begins Anglo-American rearmament years earlier under the cover of legal treaty building.

Battleships, destroyers, and land-based air cover in the Baltic force Germany to spend scarce aircraft and weapons on anti-shipping missions close to home.

Soviet participation in interwar naval limits creates a negotiating framework that could survive into a later Cold War-like rivalry.

Regular construction could advance British design generations and give Soviet yards experience that improves later completion prospects.

That cannot be assumed. The larger fleets and possible Dutch battlecruiser construction would change the circumstances substantially.

Australia would keep using British designs and might receive more cruisers or modernized Renown-class ships, rather than operate the newest battleships.

The Royal Navy is the choice here because its existing infrastructure permits immediate changes, while American expansion would first require industrial investment and continuing congressional support.

Matching foreign gun calibres points toward 16 inches, while the preferred alternative uses Britain's available 15-inch options.

More permitted tonnage would not remove the budget and population limits on Commonwealth naval expansion.

Yes, if France built a modern carrier; French construction would create the political pressure Mussolini could not ignore.

Probably south of Sardinia or around the Sardinia-Corsica gap, with reconnaissance and tentative strikes playing a large part.

A stronger Soviet Pacific Fleet could turn the 1939 border war into a naval crisis that draws Britain and the United States against Japan.

Badly, because a larger Soviet fleet would likely keep the Royal Navy larger and might preserve or produce a later British battleship class.

Continued Soviet participation after Japan leaves could turn the 1936 agreement into a political bloc against treaty outsiders.

Germany's historical Plan Z becomes still less credible when it must answer Soviet battleships in the Baltic as well as the Royal Navy.

Probably more than 10,000 tons, but dimensions alone cannot settle it without knowing draft condition, machinery, fuel, armor, and how the added volume is used.
