First of all, the Japanese confirmed that large-scale air raids pose a huge threat to naval bases, and even if the defenders are not weak and on strict alert, a large-scale fleet of aircraft can still deal a fatal blow to large warships in the harbor and important targets such as land airfields, unless they know that the enemy is coming, let all the warships drive in advance, hide or fly out the planes on the airport, but the Red Party is not the Kuomintang, and it is difficult for the devils to gain such a big intelligence advantage.

After the war, the General Staff Headquarters of the Japanese Army confirmed one thing on the basis of the oral accounts of the witnesses, that is, when the number of enemy fighters exceeded 100, even if the personnel of the Japanese airfield immediately let the fighters take off and intercept the enemy plane group as soon as they saw it, it was absolutely impossible to fly up enough fighters to intercept the enemy plane group before the enemy troops reached the airfield, and this meant that as long as the enemy plane group attacked, the Japanese airfield would certainly not be able to be saved

To this end, the Japanese staff racked their brains to come up with one approach after another, firstly, they suggested that the airfield must be patrolled by aircraft at all times, and the patrol radius should be expanded to a hundred kilometers, although this would mean a significant increase in the fuel consumption of the Japanese aviation units; They also suggested that a warning point should be set up at intervals around the airport, and that once a suspicious plane was discovered, it would immediately warn the airport by telegram or telephone, so as to make up for the omission of aircraft patrols, but this method requires a large number of specialized personnel, and also requires a lot of radio stations or telephone lines drawn in advance, and it is also feasible in the DPRK, Taiwan, and Luda areas, which have been operating for decades, and it is basically impossible to implement it in the newly occupied areas; At the same time, some staff officers suggested that a large number of small field airfields could be built instead of large regular airfields. In this way, even if they are attacked by the enemy's air forces, the losses will be relatively small, and once attacked, the number of fighters that can be lifted into the air by multiple small airfields of the same cost in the same time period is far greater than that of a large regular airfield. So this suggestion was eventually adopted. However, the cost of these methods was too high, and the intelligence department learned that the 15 th Army's air defense operations were extremely efficient, largely because of the help of radar (so the big antenna was placed there, and it would not be long to hide. ）。 The Japanese base camp, which had historically neglected radar Jishu, finally changed its previous perception and invested more money in this emerging technology

While learning from the pain, this battle also gave the devil a great inspiration. The first is the high hit rate of dive bombing and the impact on the aircraft carrier (the superstructure of the aircraft carrier is a weak point, so the dive bombing has a special effect on it. They were deeply impressed by the tremendous lethality, especially since the former coincided with the Japanese habit of frugality, but including the latest dive bomber that the Japanese army had just finalized, the Type 99 carrier-based bomber, the bomb load of the dive bomber did not exceed 500 kilograms, and it was okay to bomb aircraft carriers and thin-skinned battleships, but it was difficult to cause substantial damage to rough-skinned battleships. For this reason, the Japanese army borrowed part of the design of the German Stuka dive bomber, and made great improvements to the Type 99 carrier-based bomber, so that it could carry a high-explosive bomb weighing up to one ton, and this new type of dive bomber, known as the "99 Ship Bomber", later became the number one threat to the Allied large warships in the Pacific War. Furthermore. Since it has already suffered a big loss from dive bombers, the Japanese Navy has also taken the threat of dive bombers much more seriously than in history, of course, these are all later stories

The losses of the Japanese army in this battle were so huge that the poor performance of the air defense forces was absolutely to blame. In the past, when the airport was attacked, the devil could still use "unpreparedness", and "anti-aircraft guns are only so effective, and they can't be too demanding." But now their planes have suffered heavy losses from the air defense units of the 15 th Army more than once, and in terms of the number of air defense weapons, all the air defense weapons of the 15 th Army and even the Red Party Army are not as good as those of Lushun, as for the quality. Just by listening to the sound of the artillery, the devil pilots knew that the large-caliber antiaircraft guns used by the 15 th Army were all Japanese goods

The antiaircraft guns used by the two sides are exactly the same, but the results of the battle are very different, the devil first thinks of the difference in tactics, the air defense weapons of the 15 th Army have always been used in a centralized manner, while the Japanese army is relatively much more scattered, which is naturally very different in the face of large-scale air raids, just concentrating air defense weapons means that it is impossible to cover everything, for the devils who are reluctant to throw away even the shallow gunboats, the choice is really a painful thing

After so many actual battles, many of the Japanese pilots who experienced it began to suspect that the antiaircraft shells used by the enemy were a little strange, because whether it was the timing fuse or the fixed height fuse used by the Japanese army, it would not have much effect on the aircraft in the dive state, but in actual combat, the probability of the Japanese plane being shot down during the dive bombing was only slightly smaller, which was obviously very abnormal. Now that there was a sharp contrast in the Great Brigade, it was quickly pointed out that the anti-aircraft shells used by the enemy were probably equipped with a new type of fuse that had never been seen before, which could increase the hit rate of large-caliber anti-aircraft guns by several times, if not tenfold. This argument immediately aroused the great attention of the Japanese army base headquarters, but Kenji Dohihara, who received the task, had an extremely headache, because the organization of the Red Party was much tighter than that of the Kuomintang, and it was not so easy to penetrate even the periphery, not to mention that it was still a vital air defense force, and it was difficult to pass the political review level alone. And it is even more difficult to bring back an anti-aircraft shell weighing at least a few kilograms

However, this is the death order of the base camp, and if Kenji Dohihara doesn't want to retire early and eat dry food, no matter how difficult it is, he has to do it next. Under tremendous pressure, Kenji Dohihara, who was in a hurry to go to the doctor, actually came up with a whimsical idea, according to the information about Hu Weidong collected by the special high school, this person attaches great importance to scientists and senior technicians, so if some spies with scientific and technological expertise are sent to the past, will it be a miracle effect? Thinking of this, Kenji Dohihara's eyes suddenly opened, and a cold smile bloomed

After the war, the four aircraft carriers were picked up and repaired by the Japanese army, which made the devil understand one thing - due to the shallow water depth and the relationship that the ship repair yard was nearby, the warships that were bombed and sunk in the harbor of the naval base could be re-saloped and repaired, which made the later "Pearl Harbor Incident" very different from history in terms of process and result (to be continued.
