Old Japanese naval warship
While the Western powers were rampaging wildly with their ships and guns, Japan was also closely following suit to vigorously develop its navy. After the Japanese Navy began to invade the outside world to obtain a large number of benefits, and after defeating the Tsarist Navy in the Russo-Japanese War, not only did its prestige increase unprecedentedly, but even the status of the admiral was greatly enhanced, and then the Japanese government hoped that the Navy could encroach on resources and further enhance its own national strength, so it began to vigorously support it later, and the proportion of various funds also increased, so the Japanese Navy soon had more powerful battleships, and the combat effectiveness was so strong that even Britain, the United States and other countries began to be jealous. Eventually, Japan was forced to accede to the Washington Naval Treaty.
USS Fengxiang
But as the contradictions between countries are getting more and more, and Japan is not willing to be restricted in this way, so it later used various ways to break through the restrictions, and at the same time, the Japanese Navy also emerged a group of generals with advanced ideas, realizing that the aircraft carrier is the main force in future naval warfare, so decisively abandoned the idea of battleship decisive battle, of which the Fengxiang dirty aircraft carrier was completed in 1922, sunk as the world's first aircraft carrier in service, after which the Japanese Navy also modified some ships, and had several ships early. As the pace of Japan's foreign aggression accelerated, Japan also began to use the strength of the whole country to build aircraft carriers, Xiangfeng, Ruifeng and other aircraft carriers of varying sizes have come out one after another, and even had more than 20 before the outbreak of the Pacific Naval War, although some of them are converted light aircraft carriers, but this has also greatly enhanced the strength of the Japanese Navy.
Japanese heavy aircraft carriers
Since there is such a strong fleet base, the Japanese Navy also attaches great importance to the quality of soldiers, especially artillery and aviation capabilities, so the intensity of training is very huge, and even causes soldier fatigue training accidents, but it is precisely because of this that the Japanese army's combat ability has rapidly improved, so it is eager to invade and expand to prove its strength, after all, Japan has invested a lot of money for the fleet, but later did not get any returns, which makes the Japanese Army have complaints, but it is undeniable that after so many years of development, The strength of the Japanese navy far exceeded the normal level of Japan in the same period, and it had always regarded the American fleet as an adversary, so in order to maintain energy constraints, it began to focus on the resources controlled by countries such as Britain and the United States in Southeast Asia.
Attack on Pearl Harbor
At this time, the Japanese Navy, which prides itself as the world's first navy, has great confidence, and desperately hopes to be able to start a war against the United States, force it to give up southeast Asian resources by force, and in order to attack Pearl Harbor first, it seriously damaged the US fleet, and then the Japanese Navy continued to move, seized several islands of the US military to build military bases, and then defeated the British Royal Fleet in the Indian Ocean Naval Battle, under which the two countries with powerful navies in the world were defeated by Japan, although the United States sent a fleet to fight with the Japanese army soon after the Coral Sea Battle. At the same time, a light Japanese aircraft carrier was sunk, but it also paid a heavy price, one heavy aircraft carrier was sunk, and the other was also seriously damaged and needed to be repaired, which shows how powerful the Japanese Navy was at that time.
Battle of Midway
The Japanese Navy relied on its strong strength to launch an attack on the United States and sank a US aircraft carrier, so what was the outcome of the Japanese Navy? In the early days of the Pacific Naval War, the Japanese army in order to cut off the strategic connection between the United States and Australia, launched an attack on the southwest Pacific islands, but because the United States also realized the importance of the islands, and the Japanese army could not fight for a long time because of the supply difficulties and finally had to retreat, and then in order to annihilate the remaining aircraft carrier fleet of the United States, the Japanese Navy sent the main force of the combined fleet to launch the Battle of Midway, but after a battle, Japan not only could not gain the advantage, but it was sunk by 4 aircraft carriers and a cruiser. Hundreds of fighters and thousands of people were also lost, and the final loss of strength could only be temporarily entered into the strategic defense stage.
Battle of Guadalcanal
After such a major victory, the US military also began to carry out a local counteroffensive, and carried out dozens of naval battles of varying sizes with the Japanese army near Guadalcanal, both sides lost a large number of combat ships, but the difference is that the US casualties are only 5,000, while the Japanese casualties are as high as more than 20,000, and at the same time, the airfield that is about to be built is also lost, not only can not be used to make up for the loss of the aircraft carrier, but also made it an important base for the US counterattack against the Japanese army, and the Japanese navy has invested a lot of manpower in order to retake it. The remaining navy was also used to engage in naval battles with the U.S. fleet, and a large number of fighters were sent from nearby bases to compete with the U.S. military for air supremacy, but because of the serious lack of naval strength, the Japanese Navy again lost several warships, and the unprotected transport ships were quickly sunk.
Air raids on the Rabaul base
Unable to provide logistical supplies to the Japanese army on the island, and the Japanese fighters also because there is no aircraft carrier projection, and the base distance is relatively far, so it can not be sustained combat, once wounded there is no airfield that can be used to force a landing, so the losses after a battle are very serious, and it is impossible to provide fire support to the ground army, so after the end of the battle, the Japanese army's superiority in strength is also indifferent, Japan is unable to regain the strategic initiative, completely fell into a passive situation, at this time the Japanese navy has completely abandoned the attack, At the end of 1943, fighters were sent to air raid the important Rabaul base of the Japanese army, and the Japanese warships had to abandon the base and retreat in order to prevent losses, and the US military also implemented the island-hopping tactic in order to further exert pressure on the Japanese mainland.
The warship sank
Forcing some of the Japanese troops on the islands into a situation of isolation and helplessness, and the Japanese army in order to prevent the U.S. army from occupying Saipan, but also sent the last 9 aircraft carriers and a large number of warships to carry out the Battle of Mariana with the U.S. fleet, but after the last battle, the Japanese lost 3 aircraft carriers again, and at the same time 3 aircraft carriers were damaged and could not fight, in addition to the warships were also sunk several, the carrier-based aircraft were almost completely destroyed, after this battle, the last strength of the Japanese Navy also suffered a devastating blow, so in the final Battle of Leyte Gulf, Even if the Japanese army gave everything it could to confront the American army, in the end not only the aircraft carrier was completely sunk, but also all kinds of warships were also lost, and after the war, they almost lost the ability to fight in the ocean, and the once powerful fleet completely collapsed.
The aircraft carrier was badly damaged
The Japanese army had the advantage in the early stages, but lost successive defeats in naval battles and eventually lost its ocean-going capabilities, so why was the Japanese Navy defeated so quickly? The first is the industrial gap, in the Coral Sea Naval Battle, both Japan and the United States have aircraft carriers were seriously injured, need to return to the harbor for maintenance, but before the outbreak of the Battle of Midway, the United States seriously injured aircraft carrier has completed the repair and re-entered the battle, while the Japanese aircraft carrier is still parked in the harbor can not participate in the war, this miraculous maintenance ability has exceeded Japan's imagination, and in the two sides continue to carry out fierce naval battles, the advantage of this maintenance speed is also increasing, the US warships often only need a short time to recover, However, the warships in the Japanese military port need to wait a long time before they can be repaired, and the American warships can regain their numerical superiority as soon as they come and go, and the Japanese can only use all their strength to counterattack, praying for a miracle to turn the tide of the war.
U.S. fleet
In addition, there is also a huge gap in the national strength of Japan and the United States, the Japanese army was able to gain superiority in the early stage of the naval war, which was caused by Japan's deformed development for decades, for which even the plundered wealth was all invested in the construction, and although the number of aircraft carriers in the United States was relatively small, but that was because it was not needed for the time being, so after Japan's sneak attack on Pearl Harbor, the United States declared war on Japan and became involved in the war, the government quickly invested a large amount of money in the military, and soon it could build a fleet, which is far from the limit of the United States. As long as there is a need, it can continue to be put into construction, and the army's various logistics materials are large enough, on the contrary, the Japanese army has no ability to replenish after the loss of warships, and with a large number of materials put into the battlefield, even follow-up maintenance can not be guaranteed.
Decipher
The Japanese army can only take the residual strength to fight with the still growing US army, and the result is that the loss is more serious, more passive in the Pacific theater, and in addition to the scientific and technological gap between Japan and the United States is also very large, the US fleet is not only more advanced, the weapons are more powerful than the Japanese warships, even the fighters have innate advantages, and the Japanese fighter technology is stagnant, can only rely on luck and pilot ability to fight with the US army, so in the Rabaul air battle, even if the Japanese army has gathered a large number of fighters for this purpose, In actual combat, it is not a small number of US fighter opponents, and in addition, the US military is capable of intercepting Japanese communication signals and has never been aware of its combat plan capabilities, and in the Battle of Midway, the US military relied on some intelligence, plus its own deduction, so as to judge the Japanese military battle plan, and was not tempted by its false intelligence to disperse its strength.
Ambush Yamamoto Fifty-Six
Although Japan also began to find all ways to evade, bringing great trouble to the deciphering work of the US military, but the US side can also obtain intelligence by salvaging the Japanese codebook, or increasing the deciphering efforts, even the myth of the Japanese Navy Yamamoto Fifty-six is because the itinerary was discovered by the US military, but it will be ambushed by the US warplane and died, so although the Japanese fleet is huge, but it is like a one-time, once its own tactical plan fails, it does not bring a blow to the enemy, then it will be too big to continue, then it will be too big to continue, The United States often does not care about the slightest gain or loss, even if it fails, it can quickly regain its strength, that is, the fault tolerance rate is very high, and the failure of the Japanese Navy in such a situation has become inevitable.
