Could a Modern U.S. Aircraft Carrier Defeat the Entire Imperial Japanese Navy of World War II?

[media=https://youtu.be/474RR1ETgyk]

My response:

I feel you have greatly underestimated the impact a Nimitz-class battle group would have in World War II. Once Admiral Nagumo's First Air Fleet and most of its accompanying battleships and cruisers are sunk in the Central Pacific, just what do you think Admiral Somerville's Eastern Fleet is going to be doing? Resting on their laurels in Madagascar? The Royal Navy will be only too happy to take the fight to Indonesia in exchange for future tech blueprints, thus ensuring no further forays by the IJN towards Hawaii in 1942 or later.

Existing U.S. naval forces for convoy duty and U-boat hunting in the Atlantic no longer being play means the British have to make up for the losses. But they don't need Somerville's force of aircraft carriers and slow battleships to do that. Instead, with knowledge of the past, the super-carrier's officers pass on knowledge to the First Sea Lord, Admiral Dudley Pound, on how to deal with the wolf packs and the disaster that befell Arctic Convoy PQ 17 in July 1942 doesn't happen.

Futhermore, per own your time-travel rules, the U.S. Army Air Corps hasn't disappeared and therefore its pilots can be quickly trained to operate off a Nimitz-class carrier (Col. Jimmy Doolittle would see to that), thus saving on the wear and tear of the carrier's own air wing while biding time for the U.S. to produce the necessary jet fuel those planes would need for operations in 1943. The carrier's escorts will thus also have plenty of fuel as well to operate with the carrier.

While the Japanese are in shock for the rest of 1942 (the losses they sustain are much greater than losing four carriers and a few cruisers at Midway), the U.S. takes advantage of the lull and some of the carrier's pilots are sent stateside to train new U.S. navy pilots (mirroring how the USN sent experienced pilots back stateside to conduct training). While modern day pilots might not be as familar with the World War II aircraft being built as the early World War pilots were, but they are experts at tactics. And so when the fighting resumes in earnest in 1943, the U.S. will have well-trained pilots for the new carriers that will soon be commissioned. The IJN, meanwhile, will have lost nearly all of its experienced carrier pilots during that battle in the Central Pacific.

The IJN won't be doing anything for the rest of 1942, not with the bulk of their fleet sitting at the bottom of the Pacific. When 1943 rolls around, the Royal Navy will probably not only lend the U.S. one of its carriers, HMS Victorious, for six months as it did in the real timeline, but probably another carrier as well.

The speed at which new ships come into service is probably going to increase a little as shipyards won't repairing damaged ships that all suddenly disappeared. And with their knowledge of the past, the Nimitz-class carrier's officers will be instrumental in getting the Navy Department to put a greater emphasis on submarine production. Manitowoc was producing subs in 9-10 months, much faster than either the Portsmouth Navy Yard or the Mare Island Navy Yard. The result is more subs are built and at a quicker pace that in the old timeline. Japanese merchant shipping losses really didn't have a big impact until the 4th quarter of 1943, so there's plenty of time to build the necessary subs and train the necessary crews.

In the meantime, Royal Navy subs will pick up the slack. So Japanese merchant shipping losses not only continue to rise, but probably exceed historic levels, leaving what's left of a battered IJN with even less fuel for combat operations than in the old timeline. Many IJN admirals were already cautious and finding out they are facing a super-carrier from the future will make them even more so.

Landing craft will also be made a priority (and not just for the Pacific). Also, the Nimitz-class crew will know what mistakes were made in Europe, too, and will advise American and British leaders. President Roosevelt, with this new knowledge, is therefore now determined to shut out Stalin at the Tehran Conference. So there ends up no agreement for Soviet post-war occupation of the Kurile Islands.

And while D-Day still takes place in June 1944, the U.S. will know of the dangerous storm that destroyed Mulberry A in the third week of June. During the invasion itself, the firepower of the U.S. battleships Arkansas, Nevada and Texas will be replaced by the RN battleship HMS Malaya (which had been held in reserve at Scapa Flow for shore bombardment if needed), battleship HMS Valiant and battlecruiser Renown (both which will be recalled from the Eastern Fleet), all with 15" rifles.

The fast (and only remaining active) U.S. battleships at this point in the war - Alabama, Iowa and New Jersey - will remain with the Pacific Fleet, as their bombardment capabilities will be needed all the more. (I am assuming that Nevada won't return?) Once the three RN ships are no longer needed off Normandy, they will be sent to back to the Pacific, Renown perhaps operating with U.S. carriers due to her speed.

But there are three other fast battleships with 14" guns that can not only provide shore bombardment but help with carrier protection: the three King George V battleships; the KGV, Duke of York and Anson. They were up in the North Atlantic on convoy duty in case there was a need for them to go up against the German battleship Tirpitz, based in Norway. But, with knowledge of the past, it's likely a couple F-18 Super Hornets from the Nimitz-class carrier will be transferred to Great Britain. Flying from Scapa Flow to attack Tirpitz in Trondheim perhaps in October 1942, they will knock the battleship out of the war for good. And if HSM Duke of York doesn't sink Scharnhorst in December 1943 it will only be because the German battlecruiser will also be taken out by the F-18s.

Anti-aircraft operations in the Pacific will be enhanced by the Ticonderoga-class cruiser and the two Burke destroyers.

An even greater emphasis is placed on the supply chain and Gen. Patton's Third Army isn't running out of fuel. Furthermore, Operation Market Garden is a rousing success, thereby preventing any Ardennes offensive in December, and the war in Europe ends by Christmas 1944. Berlin is captured by American, British and Canadian troops. The post-war map of Europe will look quite different indeed.

In the Pacific, Gen. MacArthur's island-hopping campaign is even more efficient than it was and knowledge of the past helps speed up the Manhattan Project by several months. In fact, the war may end while President Roosevelt is still alive, with V-J Day occurring perhaps as early as the end of March or early April 1945.

@beckyromero Based on @SW-User's suggestion, and just for yuks, I asked the question of Google's Bard. Bard appears to have assumed support of a carrier group.






A single modern U.S. aircraft carrier like the USS Gerald R. Ford would have a massive advantage against the entire Imperial Japanese Navy (IJN) of World War II. Here's why:

Superior Technology:

* Aircraft: Modern carrier-based jets like the F-35C and F/A-18E/F Super Hornet outclass all World War II Japanese aircraft in speed, range, maneuverability, weapons systems, and avionics. They can engage at much longer distances with precision-guided munitions, making IJN fighters and bombers virtually ineffective.

* Electronics: Advanced radar, electronic warfare systems, and communication capabilities far exceed anything available to the IJN. This allows for superior situational awareness, targeting, and coordination across the carrier's air wing.

* Defense Systems: Modern carriers utilize layered missile defense systems with advanced radars and interceptors, capable of deflecting numerous types of aerial attacks. The IJN possessed no such technology.

Operational Advantages:

* Logistics: Modern carriers are nuclear-powered, eliminating the need for frequent refueling like oil-powered IJN ships. This provides superior operational flexibility and endurance.

* Support Network: The carrier operates as part of a carrier strike group with destroyers, cruisers, and submarines, providing coordinated defense and offensive capabilities far exceeding anything the IJN could muster.

* Training and Experience: Modern sailors and pilots undergo rigorous training and simulations, resulting in superior skills and tactics compared to World War II crews.

However, it's not entirely one-sided:

* Kamikaze attacks: Though largely ineffective against modern defenses, suicidal attacks could damage the carrier and cause casualties.

* Submarines: While modern anti-submarine warfare capabilities are advanced, there's always a risk of surprise attacks.

Overall, a modern U.S. aircraft carrier would overwhelmingly defeat the entire Imperial Japanese Navy in a hypothetical battle. The technological and operational disparities are too significant for the IJN to overcome. It's important to remember that such a comparison involves comparing technology developed decades apart, and direct comparisons aren't always perfect due to unforeseen factors.

It's not quite that simple.

Per the YouTube video, the scenario was that the carrier (although I and many readers disagree with the creator's assumption) is that no nuclear-powered submarine would accompany it. And the battle group would only have one Ticonderoga-class cruiser (that's standard), only two Arleigh Burke-class destroyers and no support ships.

Althought the carrier is nuclear-powered with virtually unlimited range (assuming it isn't due for a refueling of its reactors), the cruiser and the destroyers are not. They can't steam with the carrier all around the Pacific hunting down IJN ships forever. They need refueling, which means the carrier would have to return to port as well. It can't take a chance being alone with IJN subs lurking about.

Furthermore, the carrier doesn't have an unlimited supply of aviation fuel. So its helos can't go anti-sub hunting forever, either. And its attack wing will be limited, not only due to fuel constraints, but also ordiance.

Per the scenario, all then-active U.S. Navy ships and personnel (assuming both in the Pacific and the Atlantic) "disappeared" at the end of May 1942 (before the Battle of Midway). Since the YouTube video presumably meant only active duty personnel "disappearing", there would be plenty of recently retired officers and personnel that could help make up for some of the losses. The U.S. had a much bigger navy, in terms of ships and personnel, coming out of World War I than it had entering World War II.

Although U.S. ships then under construction will eventually enter service, that will take some time. Essex (CV-9) would be the next carrier available, but not until December 1942. The U.S. would only have one battleship (the USS Alabama) available in 1943; the Iowas won't start entering service until 1944. Many carriers, cruisers and destoyers will start entering service in 1943 and U.S. production capabilities will replace the "missing" subs and aircraft.

But the point is, one Nimitz-class carrier, the Tico and two Burkes won't be able to win the war alone (not unless nukes are involved). They can't be everywhere and it will take time for jet fuel to be produced. Missiles? Forget it. What they have is it. So "dumb" bombs will have to suffice - and that would mean risking irreplacable modern aircraft in bombing runs. And there's no spare parts for those jet aircraft, either.

Could that super-carrier and its three screening ships wipe out the Japanese fleet heading to Midway? Absolutely! But then Admirals Fletcher and Spurance did pretty much that with what they had in 1942. And the war still continued until the Japanese surrended in September 1945.

It will take time to defeat the entire IJN.

The bombing of Japanese cities in the lead-up to the atomic bombs was only possible with the invasions of islands within range of our B-29s. That can't happen with just a one Nimitz-class carrier. It simply doesn't have the amount of planes needed, nor the ordiance, to fend off waves of Japanese attack aircraft. Nor can the Tico and the Burkes shoot down every Japanese aircraft, either. Nor can that battlegroup alone carry all the troops and material that will be needed to capture New Guinea, the Phhilippines, Guam, Iwo Jima, Saipan, etc.

But my conclusion, disagreeing with the video author's contention of the war not ending until 1946, is that the arrival of the modern ships - despite the "disappearance" of the entire U.S. Navy then existing - along with U.S. production capabilities and the "knowledge" of what was from the modern crew, along with some strategy and tactics that were overlooked, would result in a defeat of not only Japan but of Germany as well months before their actual surrenders.

I think a better scenario would have been for the Binkov's Battlegrounds to do this:

During the Battle of Midway in June 1942, the Japanese destroyer Arashi continues its search for the USS Nautilus, after the sub's unsuccessful attack on the Japanese fleet. As a result, Enterprise Air Group Commander Lt. C. Wade McClusky, Jr. doesn't spot Arashi steaming at full-speed to rejoin the battlegroup. The planes from Enterprise don't find Nagumo's carriers and turn back due to being low on fuel.

Nagumo's aircraft have now successfully changed their ordiance for an attack on the U.S. carriers. The result is a disaster for the U.S. Navy. Enterprise, Hornet and Yorktown are all sunk during two waves of attacks, along with several heavy cruisers.

Even worse, the carrier Saratoga is torpedoed and sunk on its way to Hawaii, leaving the U.S. with no carriers at all in the Pacific. (The Ranger and Wasp are in the Atlantic.)

Midway is then successfully invaded by the IJN and Admiral King orders Admiral Nimitz to withdraw with what little remains of the U.S. Pacific fleet to the West Coast. Nimitz is probably also relieved of command at this point.

The U.S. will still have a few fast battleships, as well the old battlewagons raised from the mud at Pearl Harbor, some of which, like Nevada and West Virginia, will be out of action for a couple years.

Then, in mid or late July 1942, as the Japanese are about to launch an eight carrier attack on Hawaii to destroy its capability as a naval base and blockade it in prelude to an invasion in 1943, that's when the rift in time occurs and the Nimitz-class carrier shows up with a Tico and the two Burkes.

Once whoever replaced Nimitz as CINCPAC and the leadership in Washington get over the fact that time-travel is in fact real, not to mention getting over the shock of perhaps a female admiral being in charge of the modern carrier group with African-American officers in command of one of the screening ships and another in command of the air wing, planning gets underway to defeat the new Japanese threat. That's when the moden carrier battlegroup obiterates the IJN fleet heading to Hawaii.

From there, not too much changes. The U.S. will have a few more battleships and heavy cruisers. More destroyers, too, but their lack of range won't matter much. Without the loss of all its submarines, the undersea war on Japan can continue, but with the loss of Midway as a base their impact will be minimal in 1942 (as it was anyway due to the torpedo debacle).

In this way, there is no mysterious "disappearance" of all U.S. Navy ships in both the Atlantic and Pacific, along with all naval personnel.

This would be a good question for chatgp

@SW-User

I doubt, by itself without input, it would consider enough variables and strategy.

A year or so ago, I read an article by someone who tried to do that with the "Rome, Sweet, Rome" time-travel scenario.

[media=https://youtu.be/bF8eYjm6oNc]

The author had to keep telling the chat what to consider, percentages, etc.
