What happens if WWII took place as scheduled... after 1942? (Patreon)

The premise concerns expectations that a major European war would come in 1942 or later, rather than a date agreed by the belligerents.

Three more years would let Italy recover from the Abyssinian War, complete ships already in hand, and expose the limits imposed by its yards, fuel, and industrial base.

Extra factories and money would not immediately supply the slips, cranes, and machinery needed for a larger Italian fleet.

France's late rearmament makes a 1942 war especially consequential: planned submarines, destroyers, cruisers, carriers, and modern capital ships could be in service.

The French submarine programme includes specialised minelayers whose value depends on carrying mines to useful positions.

Algérie's design is assessed against the technology of its own time as a starting point for later French heavy cruisers.

If Yamato's 18-inch guns and speed became known before war, British and American planners would have to react before committing fully to the carrier age.

A delayed war could bring Taiho-style carrier development, radar, and stronger anti-submarine work, while leaving Japan's pilot pipeline and merchant shipping constraints unresolved.

Taiho and British armoured carriers make bomb penetration more demanding, while torpedoes retain their ability to cause flooding below the waterline.

Japan would probably postpone an immediate A-150 programme because its cruiser shortage and wider fleet requirements still need resources.

National armed forces chose technologies that suited their research base, skills, and resources, so the outcome of the war alone cannot rank every choice as advanced or backward.

Countries outside the fighting can still lose access to affordable materials as belligerents buy up world supplies.

The Soviet Union would enter a delayed war further through rearmament, with potential access to foreign turbines, boilers, guns, and naval construction expertise.

A single hostile carrier can force an opponent to maintain several carriers across deployment, training, transit, and maintenance cycles.

Germany might finish more cruisers and begin H-class construction, yet its design bureaucracy, shipyard scale, budget, and competing army and air-force demands rule out a completed Plan Z by 1942.

The Hunt example separates political pressure for rapid orders from the professional duty to check a design.

A delayed European war could postpone the large American carrier and destroyer expansion associated with the 1940 Act.

Continued peace could encourage a small number of protected Yorktown-type carriers before combat demonstrates the case for a much larger carrier force.

Enterprise was too new to be an obvious retirement candidate; specialised night operations are a more plausible possibility.

Britain's existing escort programme, carrier plans, naval aviation reform, and radar deployment make a delayed war especially difficult for a submarine-only German strategy.

Existing escort orders could provide both ships and a trained reserve before an Atlantic convoy campaign began.

Additional peacetime gives the Royal Navy a full aircraft generation under naval control and more time to develop its pilot and navigator pipelines.

A later war gives radar, stabilized mounts, and other projects more time to develop before wartime pressure shifts effort toward production and fielding.

Successive H-class proposals grow from roughly 60,000 tons to about 130,000, while larger guns bring their own drawbacks.

The expectation is that production and frontline use would largely have moved on, with secondary employment still possible.

Canada, Australia, India, and other Dominion forces can grow in a delayed-war scenario, although capital ships require trained personnel, dockyard support, and years of institutional preparation.

An Australian shipbuilding programme could draw on British specifications and constructor experience.

A larger Indian navy would face competition for technical personnel and resistance over its institutional power.

A stronger Japanese fleet could encourage an Australian submarine force and renewed attention to Singapore's defences.

British orders put money into Canadian shipbuilding and could give Britain a reason to seek Canadian crews for some of the resulting ships.

Without the pressure of war in 1939, the US Navy may retain a small Buffalo force while development proceeds toward a fighter closer to the Hellcat.

Existing 15-inch guns and support arrangements could make the Vanguard route cheaper, while Britain retained its King George V and Lion types.

A request is unlikely while existing manpower shortages made another large crew difficult to provide.

The three scenarios begin with a 1942 European war, a Pacific war starting first, or a coordinated German-Italian attack followed by Japanese intervention.

It could delay the campaign, but it would not stop the later American carrier and destroyer expansion.

Without combat experience, the Bf 110 could remain attractive enough on paper to receive greater emphasis.

By 1942, British plans already provide a strong capital-ship force, while a completed Plan Z remains a much later infrastructure problem.

The G3 battlecruiser is the closer successor in design thinking, while the Admiral and Renown classes follow different paths.

Either is possible, depending on how the war begins.

The preferred expectation is to retain the King George V design and build Lions for the larger armament.

The estimate puts the practical limit around 1942, already a considerable stretch for the German economy.

Only under a tight set of assumptions, including close economic control and continued access to relatively cheap Soviet resources.

There are many treatments, but credible versions must respect construction time, industrial capacity, and the absence of wartime production programmes.

The answer favours a combination of surface ships and submarines.

Graf Zeppelin is favoured on the strength of its air group, provided it can get that air group into action.

Probably not in their historical forms, because those designs reflect wartime experience that this timeline has not yet produced.

Italy could rebuild some stocks after earlier campaigning, depending on political and economic choices.

They would improve shipboard defense, but the aircraft attacking those ships would also be more capable after three additional years of development.

Probably, if Italy were still preparing for a major war.

The answer is doubtful; H-39's diesel machinery would help without making the entire programme affordable.

The naval preference described here favours 16-inch super-heavy shells and rate of fire, although knowledge of Yamato could create pressure for 18-inch guns.

Only if it adopted practices that historically emerged from wartime losses, since extra peacetime alone would not reveal the same training problem.

They could improve the stockpile, but German planning still appears to underestimate the inefficient fuel consumption of wartime naval operations.

A direct revival is unlikely, although ideas such as a 16.5-inch gun could be reconsidered.

The explanation centres on the attraction of possessing the largest gun, without a clear practical ship to carry it.

It would require cooperation between the German services that the scenario does not make likely.

Around six could be completed, based on the ships already being built and likely to finish.

National programmes would keep working, but peacetime research would not match the concentrated resources and urgency of the Manhattan Project.

No. Without a wartime emergency, merchant construction stays closer to normal patterns, although active shipyards could still turn out more modern merchant tonnage.

That hypothetical force would still be short of escorts.

A destroyer's charges detonating beneath a battleship after a collision provide one possible mechanism; the answer does not identify a Taffy 3 case.

They could help if made to work, but the answer is doubtful about early operational success.

Money matters, but research also depends on trained scientists, engineers, institutions, and the capacity to turn ideas into working systems.

Yes; British U- and V-type development is offered as a likely area of progress.

The 27,000-ton Implacable design was already part of prewar development and remains a plausible continuation.

Probably not, because Type XXI development depended in part on research Germany acquired through later conquests.

More time gives France, Britain, Poland, and smaller states more radios, vehicles, artillery, aircraft, training, and defensive preparation, while Germany retains serious logistical limits.

The land-war comparison links production continuity and plentiful lorries to the ability to sustain mobile operations.

Continued tank production and sales between partners could give smaller armies armoured formations before a delayed war.

Extra time gives communications equipment and joint training a chance to catch up with the forces being expanded.

Improved fighters and tanks could make Poland a harder target without removing its dangerous strategic position.

In a 1942 European war, a Norwegian operation could bring a German surface group into range of a much larger Anglo-French force with more carriers, capital ships, radar, and trained air groups.

Continued aircraft development could bring a Reppu-type successor forward without the wartime pressure to concentrate on Zero production.

The four-ship estimate assumes Europe goes to war in 1942 and the Pacific conflict follows later, around 1944.

One illustrative response combines sixteen 16-inch guns with a projected 30-knot speed, at a substantial cost in size and maintenance.

If France stops the German advance, Italy faces French North African positions as well as British forces.

The comparison emphasises repeated British attacks alongside the larger concentrated strikes favoured by Japan and the United States.

The estimate allows roughly one completed Italian carrier by 1942, while British carrier growth could support a larger harbour attack.

If Japan attacks first, Britain, France, the Netherlands, and the United States begin as allies before Germany acts, while a still-intact French empire makes Malaya, Indochina, and the Philippines harder targets.

Britain's T-class submarine withdrawal was gradual and driven by Mediterranean losses, so a war delayed beyond 1939 leaves more of the force in Asia as a deterrent and reserve.

Older carriers and selected capital ships could watch Germany and Italy while much of the modern Anglo-French fleet fought Japan.

Sending German or Italian forces to support Finland would conflict with reliance on cheap Soviet resources.

A stronger armoured force makes the fall less likely, although leadership and Japan's own equipment still matter.

Continued fighter replacement could strengthen Far Eastern forces through aircraft transfers and opportunities for short-service officers to gain experience.

More consistent radar use, stronger air-defence discipline, and combat air patrols could reduce the surprise available to a later Japanese attack.

Expected command rotations make Cunningham a plausible British commander, while American succession and Somerville's health remain separate questions.

An illustrative fleet combines three Iowas, three Lions, and three Richelieus against four Yamatos.

A Polish destroyer serving alongside major Allied fleets could carry political significance beyond its individual fighting power.

The reply points to Germany's invasion of Poland and the German-Soviet agreement; a delayed-war scenario must change those events.

A war centred on Japan gives Britain a reason to keep building ships intended to answer the Japanese battle fleet.

The third scenario imagines Germany and Italy attacking Poland and Greece together, but finds their stronger armed forces still constrained by Allied production, French resistance, and uncertain Soviet choices.

Probably not, because the historical bomb required the combined resources, expertise, and urgency of several national programmes.

More vehicles, radios, and practice could let Britain and France act sooner after a German attack on Poland.

Churchill's later wartime prominence should not be projected back onto the government making decisions before war in 1939.

The illustrative balance sets sixteen new Anglo-French capital ships against eight German and Italian ships, with carriers threatening fleets in port.

Italy could remain in a land stalemate unless the Allies undertook amphibious operations, while Soviet intervention could open another front against Germany.

A Japanese attack could bring the Allied powers together, but the available response depends on the course of the European war.

If H-39 enters service in 1943 or 1944, its opponents also gain time to develop larger capital ships.

A different decision is plausible, although the government and its priorities would also depend on how the crisis developed.

One such carrier would have a limited effect on its own; adopting the design across the fleet could improve carrier survivability in action.

Probably not, because night flying consumes pilots at a rate Japan's elite-focused training system is unlikely to accept.

Its fighter defense improves, though some strike capacity may be lost and the British aircraft facing it improve during the same peacetime interval.

Yes, for reconnaissance, fleet air defense, and long-range anti-submarine work, even where it is less suited to a classic strike-carrier battle.

Development would continue, with Britain and Frank Whittle presented as the likeliest early leaders in putting a jet into service.

The likely continuation is the 27,000-ton Implacable type, which provides more room for protection and subdivision.

Britain would still have reasons to prefer fleet carriers with greater strike capacity; light and escort carriers answer different demands.

They would be useful if reliable, but operational readiness by the relevant date remains doubtful.

No such ship is likely by 1942 because the Indian Navy lacks the time, institutional support, and political freedom for a battleship programme.

Newer aircraft could perform that work without preserving an older airframe solely for the role.

Airborne early warning is the more plausible development, while aerial refuelling remains less likely despite active interest.

It would probably be discarded once possible, although British rocket research would continue along more promising lines.

A substantial refit is expected for both Repulse and Hood.

Some problems would remain, but repeated engine changes caused much of the historical disruption and are less likely before a delayed war.

Replacement by 20 mm weapons is considered likely, with older low-velocity weapons also under pressure.

Their development was already underway, so a broadly similar timetable is plausible.

A slight delay is considered possible if the war overlaps their introduction.

They might be awkward and less suitable for a close fight with a fully worked-up German or Italian cruiser, but they could still be useful in the Baltic and Black Sea.

Probably not by much, because three years is too short for a wholesale turnover and the missing wartime experience changes who rises.

A programme becomes plausible around 1943 if the war continues and creates demand for more carriers.

Guided weapons continue to develop, but heavier investment in conventional fleets can delay offset technologies that historically grew from naval weakness.

Berlin flak towers are plausible, but the Atlantic Wall depends on a coastline and captured resources Germany does not yet possess.

Potentially. Phibun Songkhram was a political survivor willing to follow the side that offered the safer course.

Only if the United States made the unlikely mistake of pursuing into a prepared attritional trap across the western Pacific.

It would strengthen gun-armed destroyer numbers and could accelerate 4.5-inch weapons, at the cost of fewer torpedo tubes.

The estimate calls for at least two large shipyards and multiple dry docks, alongside the capacity to support the ships.

The sequence given here puts Hood into refit in 1940 after Renown returns.

A 1940 start suggests a return around 1942; starting in 1941 pushes it toward 1943.

The comparison identifies recurring problems in decision-making, research coordination, production capacity, and adapting established plans, while allowing for individual exceptions.

The explanation for Britain's attack distinguishes respect for French naval competence from distrust of the government controlling the fleet.

Some improvement is possible, but three years limits its scale.

A likely British design would be larger and better protected, with about eight 9.2-inch guns and roughly six inches of armour.

Bismarck would probably meet Lion-class ships instead of Hood, creating a faster British force with more 16-inch guns.

Further carriers are plausible, but H-39 construction competes for the yard capacity they would need.

Yes, because harbor attack was a long-standing Royal Navy doctrine supported by specialized shallow-running torpedo techniques.

Not necessarily, because peacetime may not create the pressure to confront a defect that wartime operations made impossible to ignore.

It could participate, though torpedo attack held a different place in RAF planning than in naval aviation.

No, because exploration, roads, drilling, pipelines, terminals, tankers, and production capacity would need to begin much earlier.

The defenses would improve, but more carriers and mixed fighter, dive-bomber, and torpedo-bomber attacks would divide the ship's anti-aircraft effort.

A larger sortie would draw a stronger British concentration, with carrier attacks helping slower heavy ships catch up.

Those ships could be useful in the Baltic or after operating from exile.

More familiarity could improve confidence and reduce poor use of the equipment.

It could provide useful local air defence, without changing the outcome of the war by itself.

The small number of carriers would create too little demand to determine the whole fighter programme.

Retention is likely for as long as resources allow.

It could improve lubricants and some machine performance, but it would not eliminate Japan's broader fuel and strategic constraints.

Quadruple arrangements are considered plausible, with several designs having been explored.

No. The stockpile and plan were intended as retaliation to deter Axis use of comparable weapons.

Probably, given the Alaska class, British interest in 9.2-inch guns, and the German panzerschiffe.

Even a working reactor could produce electricity faster than German industry could convert its factories to use it.

An expanded reporting network could reveal military movements while making repeated sightings harder to distinguish from separate forces.

That force could change the attack, but making all of it available by 1942 requires more than the established scenario supports.

A later conflict is possible, but the answer does not support a firm date or assume the same postwar settlement.

The expectation is continued fleet-carrier construction on the Taiho line.

Possibly, although limited naval strength could make bases and facilities a more useful contribution than ships.

The equipment could improve, but Mussolini's political distrust may still keep the North African command short of supplies and modern weapons.

It could give the Kuomintang more Allied standing and recovery time, though Communist intelligence successes keep the result uncertain.

The answer points to existing British planning for operations from China.

The estimate is a delay of roughly two or three months, without a Japanese victory following from that delay alone.

No; those events remain part of the scenario.

Britain planned two to provide aviation support far from its industrial base; American geography created a different support requirement.

It could buy a short delay, but later German attacks would undermine that explanation.

Commandos and an SBS-type maritime force remain plausible, while the SAS depends more on the North African campaign's particular circumstances.

On the design-lineage interpretation used here, extra protection leaves Hood within the battlecruiser category.

Yes; doing so could also release French port capacity for cargo.

Detection is considered likely, but that does not ensure useful warning arrives in time.

Yes. Without the historical Mediterranean losses, more boats would probably remain in the Pacific.

War could interrupt research and shift attention toward putting existing work into use.

Norway gains time to prepare and a naval campaign could become far bloodier as more carriers and modern forces enter the fight.

A Pacific-only war is less destructive to Britain's industrial economy, while a European war depends heavily on its duration and whether France remains a defensive depth.

They would risk being stranded and unable to return home.

The problems multiply sharply as more guns must work together, making an extreme multi-gun turret a punishing engineering choice.

Only after taking the Philippines, Malaya, Singapore, and the Dutch East Indies, successes the delayed-war scenario makes much harder.
