This was a great article because it describes an aspect of World War II in the Pacific Theater that many may not be familiar with. The base of the article describes the I-400, a technologically advanced submarine, the brain-child of Admiral Yamamoto. When the Admiral died, the project was stopped and Japan had to repurpose the plan for the submarine. The images for the article help the reader understand how massive this submarine was. The outcome of the war could have been much different had the timing of the I-400 been earlier. I liked the insight on how the U.S. handled the sinking of the submarine. Had we glorified the seizing of the submarine, the Cold War would have been different.

It’s interesting to think about what the Japanese could’ve done if Yamatmoto had survived to execute his original plans for the I-400s. With a ship that massive that was able to carry aircraft large enough to attack cities and then just disappear into thin air. If the Japanese were able to have the planned 18 subs and were able to fully equip them with the fighters and bombers that they wanted, the war could’ve turned out very differently. They would have a strike force that could appear, destroy, and disappear like it was nothing. The subs themselves were a technological feat and I think that it was a shame that the US sunk them instead of hiding them and researching them. I feel like the navy would be different today if those subs weren’t sunk and we were able to do an in depth research of them.

I-400 “..a massive sub…dwarfing anything the U.S had ever built.” This technology at the time, could have dramatically changed the outcome of the war if time was in Japan’s favor. Japan was just one week too late. While they were focusing on this technology to dominate the sea and air, the U.S was secretly planning the first atomic bomb attack. The U.S was so convinced that this technology was advance and could be potentially dangerous if fallen into the wrong hands. Keeping the capture of the I-400s a secret till after the war then sinking both calmed any worries.

This was an interesting a read, I found it interesting because it seems as if Japan’s plans were not very well thought out. They planned on using these submarines for many attacks, and while these attacks would have been very impactful and could have shifted the tides in favor of them they never acted on them. They planned on using them to use biological warfare on the west coast, but then decide not to, and then plan on attacking the canal in Panama. Japan had their hands on something that could have changed history, but due to what seems like lack of proper planning they were never able to fully utilize what they had created.

Great quick read that showed one of the many technological advancements that took place in the pacific war. Japan really though outside the box as they developed a whole new class of submarines; just not with an efficient solution. These new subs brought many challenges involving transporting, launching, and retrieving aircraft. The planes reduced in size to fit in the hangar. Keep in mind that only three subs were made. Each carrying three aircraft. Not much of a dent in what they were used on. Base, ship, or civilian area. The damage that they could inflict was but a mere mosquito bite in the face of the U.S. navy. The torpedoes of the i-400 would be more effective than sending it’s planes to be shot out of the sky. The whole idea just seemed to impractical. Create multiple, high cost, sea vessels with few aircraft than an actual aircraft carrier.

The I-400 is perhaps one of the most fascinating military marvels in the world, along side amazing war machines such as Germany’s P.1000. Now in retrospect we realize how impractical Japan’s plan involving the I-400’s was, what with them only carrying 3 planes compared to a traditional aircraft carriers vastly larger compliment but it certainly is an interesting scenario to think about. I do also often wonder how a modern version of the I-400 would look like, with modern technologies could the idea of a submersible aircraft carrier be feasible? Overall a fun and interesting article about an obscure piece of technology.

I have never heard about this machine. Probably, it would have been very different if Japan had used these weapons. I am glad they did not because it could have been a disaster for the world. I also like the way the U.S acted when they discovered these weapons, knowing how risky the situation was at the beginning of the Cold War, and and how dangerous it would had been if the USSR had discovered these weapons.

The idea of a submarine combined with an aircraft carrier has been explored before in fiction. However, I never thought that such technology could be possible, nor that said technology could be produced by a nation in as desperate times as the Japanese empire in World War 2. It’s strange how the US never tried to adopt such technology into their own naval vessels, given how we paperclipped many Nazi German designs and scientists, as well as pardoning major Japanese politicians and generals working for Japan during WW2

It’s truly a terrifying thought that the I-400 could sail from America, to Europe, and even make it back to Japan, considering its size. It is mystery as to how this project would have turned out if Isoroku Yamamoto was not killed. Even more terrifying, having engineers create a submarine, that large, and give it the ability to launch nuclear bombs from anywhere they wanted to. Similar to German engineers, Japanese engineers were truly ahead of their time. Creating and devoting their time to making advanced and technological ships instead of manufacturing a large quantity of them. A very spooky feeling to think what they could do with the resources these larger nations had.

A very innovative submarine, that could be a practical aircraft carrier, but through the knowledge and idea of a huge pressurized container wide enough that could hold planes is incredible. As well as the secrecy that submarine holding planes wouldn’t be very noticeable to today’s concept of an aircraft carrier. If they were to mass-produce these submarines or had shared the idea and concept to other powerhouse countries before U.S. knowledge of construction, it would have been a fairly different concept of war
