During World War II, Japan's weapon design was "advanced".

1905, Japan despicable defeated the Russian imperial navy and became a world power.

Although it was allied with the Allies during World War I, after Versailles was left out in the cold, the Japanese Empire changed its attitude of blindly following.

In 1930s, Japan tried to form an alliance with Nazi Germany and started a series of aggressive movements, trying to gain a foothold in the Pacific region. However, a series of actions by Japan eventually dragged the United States into the battlefield.

Japan also has self-knowledge and knows how powerful its opponents are. No matter in resources, economy, industrial strength or science and technology, it can't compete with it for a long time. What they should do is to completely defeat the United States by surprise in a short time and let this behemoth lose its pieces. To this end, the Japanese army has accelerated the development and equipment of advanced conventional weapons, suicide attack weapons and even biochemical weapons. In fact, Japan's war commanders don't care about the prohibition of the use of chemical weapons in the Geneva Protocol. On the contrary, they think banned weapons are particularly effective. In addition, Japan has increased its research and development efforts, exerted its strength on advanced technologies and conceptual weapons, and wanted to surprise the United States with the latest and most advanced weapons.

During the war, Japan developed hundreds of highly conceptual weapons, but a large part of them failed to really enter the battlefield. Today we will take a look at some representative conceptual equipment or tactics.

Balloon Bomb When Nazi Germany threw V2 rockets into the English Channel, the Japanese were also making their own "revenge weapons". Although Japan could not develop intercontinental missiles like Germany at that time, the Chief of Staff put forward the idea of balloon bombs.

In order to realize this weapon idea, the Japanese planned to put a bomb on the balloon, which flew to the United States along the airflow and exploded in the forest area of the Pacific Northwest about 5,000 miles later, triggering a large-scale forest fire and diverting the scarce war resources of the United States at that time.

These balloons are made of plastic paper, glued together with starch, filled with hydrogen, with a diameter of more than 10 m, and can lift objects of about 450 kg. The balloon is equipped with a fragment bomb weighing 14 kg.

The Japanese set the flight path of the balloon. If the balloon rises above 1. 1, 000 meters, it will release hydrogen. If the balloon drops below 1000 meters, it will put down the load bag filled with sand and use the airborne altimeter to measure it. Three load-bearing bags filled with sand are hung under the balloon with the bomb, and the weight of each load-bearing bag is between 1 and 3 kg. These bags are released in pairs to keep the balloon balanced. According to the Japanese idea, the balloon will rise due to the change of temperature during the flight, and will fall down at night until the ballast bag is exhausted. At this time, the balloon and the bomb it carries will fall on anything under it.

It sounds like a joke, but the first balloons were really released at the end of 1944, and landed near San Pedro, California on October 5. The next day, they arrived in Thermopolis, Wyoming, and some even landed in Canada. According to American records, there were about 285 confirmed landings or sightings.

1on March 5, 945, six Americans were killed by a bomb on one of the balloons when they tried to pull the balloons back from the forest to the camp in Oregon.

During the Giant Submarine War, the Japanese secretly built three giant submarines, keeping the record of the largest traditional power submarine in history. As part of Japan's plan to rule the Pacific Ocean, they were designed to sneak attack and intercept warships and ships passing through the Panama Canal.

The submarine is equipped with three M6A 1 aircraft, which can carry torpedoes or bombs over 800 kilograms. They are placed in a waterproof and pressure-resistant hangar. The plane was launched from the catapult at the bow. All three planes can be assembled within 45 minutes after the submarine surfaced, completing the whole process of refueling, equipment and launching.

It even designed a snorkel covered with a thick rubbery substance to absorb radar and sonar signals.

Suicide diving suits These special diving suits are specially designed for Japanese special forces to resist the invasion of Japan by allied forces. These diving suits are equipped with a mine with 15 kg of explosives.

Divers can walk underwater with 9 kilograms of lead for up to 6 hours at a depth of 5-7 meters. The specific use method is that divers go to the bottom of the enemy ship's hull and then detonate the explosives on it to sink the enemy ship.

It is not clear whether this diving suit has really been used, but there are reports that American infantry landing craft and a survey ship were attacked by suicide swimmers.

"Purple" encryption machine Germany's Enigma machine may be the most famous encryption device in World War II, but it is by no means the only encryption device. 1937, the Japanese invented the Type 97 typewriter, which was named after it was invented in Japan in 2597. This encryption device is more famous for its American code name: purple.

This machine consists of two typewriters and an electric rotor system with a 25-character letter exchange board. Just like the Enigma machine that inspired it, it can manually input plaintext or unencrypted information, but its most important innovation is the second electric typewriter, which prints encrypted information on a piece of paper (Enigma presents text in the form of flashing lights). So it only needs one person to operate. Because the Japanese change their passwords every day, the password cracker can't find the pattern in the information.

MXY-7 OKA Aircraft With the progress of the war and the improvement of the Japanese suicide attack aircraft for Kamikaze, they began to explicitly develop aircraft for this purpose. Yokosuga MXY-7 is a rocket-propelled aircraft, which made its first flight in September 1944. In order to make this machine, the Japanese use as little important raw materials as possible, and the structure of the plane is also very simple.

During the battle, Oka was hidden under the fuselage of Mitsubishi G4M and was not released until he approached the target. Before approaching the target, the plane leans as far as possible by gliding, ignites the rocket at the last moment and rushes to the target at high speed, which is fatal.

The plane was loaded with a 2643-pound bomb. Its high speed makes it almost impossible to be intercepted by anti-aircraft fire. In other words, it is very fragile when flying with the mother machine. But once the rocket is ignited, it is difficult to fly, but it is almost impossible for the enemy to intercept it. Although there are certain restrictions on its use, at least one American destroyer was sunk by this weapon.

J8M Rocket-powered Interceptor If you think this is very similar to German Messerschmitt 163 Komi, you are right.

J8M 1 should have been a licensed copy of Nazi advanced aircraft, but the German army could not transport the physical fighter to Japan (a German submarine carrying a real Messerschmitt 163 aircraft was sunk on the way to Japan), forcing Japanese designers to reverse design this advanced attack aircraft from the flight operation manual and limited technical blueprint.

In fact, considering the allied bombing in Europe, the Japanese are eager to build interceptors. Military commanders worry that it is only a matter of time before Japan launches a similar bombing. Because the flying altitude of B-29 is beyond the reach of most Japanese fighters, Me 163 is regarded as the best way to solve the problem.

Although there was no physical plane for design reference, before the end of the war, the Japanese had already tested a prototype, model J8M,1July 7, 945. J8M made its first flight in the control center, but the flight time was short and disastrous. Although the takeoff stage was good, the engine broke down during the climb, the plane crashed directly and the test pilot died on the spot. However, the Japanese were not reconciled and rebuilt.

O-I Super Heavy Tanks The Japanese usually don't care much about their tanks, although they do have some quite good tanks, including Type 97 medium tanks, because most of Japan's foreign wars, except China, are dominated by the navy and air force, and the army only plays an auxiliary role (although the air force was still under the command of the army at that time). However, at the end of the war, they had an ambitious idea. According to the idea at that time, if they were not crazy, it would be impossible to come up with such a "crazy" design, that is, to build an overweight tank. We all know that Japanese tanks have always been small and light, and there are almost no heavy tanks.

The tonnage of O-I ultra-heavy tanks is absolutely huge, and the design weight ranges from 100 to 120 tons. It needs 1 1 people to drive. This tank has three turrets, a main gun and two auxiliary guns. An unconfirmed report said that one of the tanks was sent to Manchuria, but

Ku-go Death Ray The Japanese who like to develop alternative fighting methods have also actively developed a death ray, which is a concentrated energy beam that can shoot down planes hundreds of miles away. According to the documents confiscated by the U.S. military after the war, the study of Japanese dead light began as early as 1939, and researchers developed a high-power magnetron that can generate radiation beams. Physicist SinitiroTomonaga's team developed an 8-inch (20 cm) diameter magnetron with an output power of 100 kW. However, it is doubtful whether this technology can play the role of death ray in science fiction. The calculation shows that if the beam is properly focused, it may kill a rabbit within a distance of 1000 yards, but only if the rabbit can be completely motionless for at least 5 minutes.

Flying Tanks During World War II, one of the main problems faced by the Japanese army was to transport heavy equipment such as tanks from one island to another. One potential solution is to fly, or more accurately, glide tanks.

The characteristics of these light tanks are that they are equipped with detachable wings, tail wings (stable on the tail surface of the aircraft) and take-off bodies. They were installed on Mitsubishi Ki-2 1 Sally heavy bombers. When they arrive at the combat area, they will glide to their destination like gliders, and begin to perform various tasks after landing.

The Z-super bomber is just like the bomber plan of Nazi America. The Japanese Empire hopes to have intercontinental bombers that can hit North America. With the progress of the war, the Japanese urgently need bombers similar to the American B-29.

194 1 year, the Japanese navy launched the experimental 13 attack bomber, which is a four-engine long-range heavy bomber, but the chief of staff wants a bigger, heavier and faster vehicle that can fly at an altitude of 32,800 feet and carry 22,000 pounds of bombs. To this end, the Japanese army began to develop such aircraft, including Nakajima G 10N and Kawasaki Ki-9 1. The former has a wingspan of 237 feet and a total length of 144 feet. It will be able to fly at an altitude of 25,000 feet at a speed of 590 km/h, equipped with six 5,000 horsepower engines, but due to the deterioration of war conditions.
