I know the two aerial attacks were very significant in the war, but they weren't effective as they were planned. What would need to be different/changed to have a successful and considerably meaningful impact on the German-Japanese war effort?

Note for Poll participants: Poll closes Dec 7th, 2022. You can pick up to three choices. You cannot change your votes. Ok, so awhile back, I was younger and healthier, and had ambitions to write some really good ATL's, but now I honestly think that I will never get them done, or even started...

The scenario: a US naval vessel/aircraft, or more likely, a civilian vessel/aircraft from a neutral nation or one sympathetic to America, spots Kido Butai en route to Pearl several days before the Japanese reach their launching point. The Japanese are not stupid. They cannot let the interloper...

So, taking a look at Japan's opening moves in WWII (after the attack on the USA, all the separate wars became one big war), what if they had done something different from OTL? For the purposes of discussion, let us suppose that everything is as close to historical as reasonably possible, within...

how much can Barbarossa succeed (push to A-A line) without lend lease and with Japanese invasion of Siberia will soviet have a famine and bad supply lines without lend lease food and truks? will soviets be spread thin with Japanese invasion of Siberia ?

Might be a trivial POD, but what if, instead of the surface expert Nagumo, Yamamoto himself lead the massed carrier strike on Oahu? Would there be any changes to how effective the overall strike is? Another question: would deploying midget submarines to hit after the attack have produced better...

What if the Japanese declaration of war (AKA a sneak attack) came three months later, and with an actual attack on Los Angeles?

Ok so seeing as today is the day of the attack I decided to whip up an alternate history scenario. The video below is more to set it up. - - What happens if due to better intelligence-gathering the United States knows about the attack on Pearl Harbor some time before it happens. So the loss of...

What if the US Pacific Fleet stayed based in San Diego, while the US kept all other relations with Japan as OTL. Instead of an attack on Pearl Harbour to open the war, could Japan have pulled some kind of submarine attack on the Fleet at anchor on the West Coast? Some combination of mass...

By pure chance on the early morning of December, 4th a destroyer or another radio-equipped US vessel nearly collides with a japanese cruiser and immediately starts radio transmission. Astonished japanese admiral reads the message. It starts with some encrypted junk, then a repeated plain text...

Would have been able to destroy the dry dock, repair facilities, and oil tanks? Is it known how many army and navy aircraft, and anti-aircraft batteries were still operational? Because more than 29 aircraft were put out of comission in the 1st and 2nd waves.

That's it. Ignoring politics, advancing Japanese conquest plans and naval construction, Indo-China is already fully occupied in July 1941 as it was IOTL in December of that year. Japan learns of Barbarossa and decides to throw the dice when FDR announces oil embargo with Japanese occupation of...

Say the US discovers the Japanese plans for the December 7/8 attacks on Pearl Harbor, the Pacific Islands, and Southeast Asia. How much could they do to stop the Japanese? The Japanese forces attacking Pearl Harbor, Wake, and Guam are going to the bottom for sure, but what about the Philippines...

As a future student of English Literature, Harry Turtledove was a slog for High School me to get through all those years ago. His scenarios are interesting for an alt history beginner, but he's just a terrible writer! His prose drags. But I got through the entirety of the first book in his...

The War in the Pacific, the battle for supremacy of the Pacific between the West and Japan, was the greatest naval war fought so far by humanity. Powerful fleets steamed thousands of miles to strike at the very heart of their enemies strongholds, while submarines, mines and aircraft brought...

Ok folks, here is yet another crazy sounding idea brought to you by your local neighborhood Shadow Master. In this thread, I'd like for a good discussion about using an H6K as a flying boat-bomb. The mission profile is to specially modify a number of these aircraft to put as large a payload as...

A new kind of war In the Great War, the Royal Navy invented the aircraft carrier, the first ships to be modified to launch and recover combat aircraft. Although they did not accomplish much during the war, the promise was clearly there. Soon after the war the Japanese and American navies...

I started a thread a few months ago about some World War II stuff I forgot already, but one thing I remember was that if France does not fall, Japan won't declare war on the US because Indochina doesn't fall, etc. Now the challenge here is that France does not fall [*1] but Japan still...

What if all three of the U.S. Pacific Fleet's aircraft carriers (Enterprise, Lexington and Saratoga) would have been in Pearl Harbour and at least two were sunk or damaged beyond repair on the attack. How dramatically would this change the course and maybe even outcome of the Pacific War?

in a TL I'm writing, the submarine USS Tautog encounters the Japanese fleet 250 mi north of Hawaii as they're retreating back to Japan. What kind of damage could the Tautog do? Would it survive the encounter? Would the American fleet or aircraft be able to find and attack the Strike Force?
