Anti-Japanese blood sacrifice mountains and rivers

The Chinese have an old saying that if you hit the south wall, you don’t look back. The Japanese typically don’t look back when you hit the wall. They swear that they will never stop hitting the wall. Germany used the general bombing of Japan to weaken the Germans, but the result outweighed the loss. The United States air raided Japan. Gao Fei suggested using incendiary bombs to penetrate the defense at low altitude and drop bombs quickly. Japan lacked night fighters and experienced pilots, let alone radios. With equipment such as proximity fuzes, it is impossible to implement fire interception against U.S. bombers that break through the fire fault of their anti-aircraft artillery at night. %&*";

Gao Fei proposed that the Chinese Youth Army be attached to the First Strategic Air Bombing Team, and the 55 US B29D super sky fortress bombers received were also used to bomb the Japanese mainland. Exciting, but the main reason why the Chinese Air Force is roughly divided into three parts is because of the aid from the United States. Gao Fei’s youth army air force is also incorporated into the Chinese Expeditionary Force’s combat sequence, and the Sino-US joint air force is under the command of Chennault , the rest is Zhou Zhirou's Chinese Air Force. Although Zhou Zhirou has always wanted to merge the three, but even the national government has to look at the Americans, let alone a Chinese Air Force commander. .

On the way to Shanhaiguan for inspection, Gao Fei learned that the U.S. Air Force’s B29D Super Sky Fortress bomber group, which was going to bomb Tokyo, was threatened by the Japanese super-caliber anti-aircraft guns. The intelligence of this super large caliber anti-aircraft gun.

After hearing the news, Gao Fei immediately remembered that Japan was the only country in the world that produced super-large-caliber anti-aircraft guns in history. It can be said that the Japanese were completely forced out. %&*";

Prior to this, the Japanese General Staff Headquarters had obtained information that the U.S. military was developing a super bomber with excellent performance. According to the intelligence, the bomber has a huge speed, combat radius and altitude. It is entirely possible to pose a threat to the entire territory of Japan.Anti-Japanese Blood Sacrifice Mountains and Rivers 922

However, the Japanese did not pay attention to this, because the United Fleet still had an absolute advantage at that time, but as the advantage of the United Fleet no longer existed, and the b29d super sky fortress strategic bombers from the coast of China almost looted the entire Japan After the important cities of the archipelago, the Japanese had to act. Emperor Hirohito personally ordered the development of an anti-aircraft gun that could threaten the b29d super sky fortress strategic bomber.

After the imperial palace was burnt to ruins, Emperor Hirohito has been wandering in secret refuges in various places. Many cities in the Japanese archipelago are all within the bombing threat of the US b29d super air fortress strategic bomber fleet. Under the urging of Emperor Hirohito, the research meeting quickly passed the development of ground weapons, that is, super-large-caliber anti-aircraft guns, and discussed the possibility of destroying the B29D super sky fortress strategic bomber.

Since the U.S. military's b29d super sky fortress strategic bomber bombing the Japanese mainland has a flying altitude of more than 120 meters, and the Japanese navy's largest caliber anti-aircraft gun has a caliber of 120mm, the muzzle velocity of this type of anti-aircraft 850mm anti-aircraft gun mounted on battleships It is about 70.00 meters per second. Although its maximum shooting height is 29 meters, this is only theoretically speaking. The effective shooting height of anti-aircraft guns in actual combat is about [-]% of its maximum shooting height. To defend against the B[-]D super sky fortress strategic bomber that has entered the depths of the Japanese mainland, super-large-caliber anti-aircraft guns are needed, and such anti-aircraft guns must have a maximum shooting height of more than [-] meters.

According to the calculation of Lieutenant Assistant Sakaguchi, who is in charge of ballistic calculation, if the caliber is 150 mm, the weight of the shell is about 55 kg, and the muzzle velocity is about 930 meters per second, the maximum charge can reach the shooting height of 120 meters. However, The navy already has experience in the successful development of three types of [-]mm anti-aircraft guns, so the Japanese take it for granted that as long as this gun is enlarged, a new type of anti-aircraft gun can be successfully developed in a short period of time.

The Japanese's ability to imitate is indeed very good. The new giant super-large-caliber anti-aircraft gun is the same model as the Type III 120mm anti-aircraft gun. In fact, the Japanese encountered considerable trouble during the simulation process. The shells of this type of anti-aircraft gun With a total weight of more than [-] kilograms, it is not an easy task to ensure that it can be loaded freely at any angle of fire.

The final specific solution is that when firing, two gunners carry one shell, put the four shells on the loading preparation table on the side of the gun first, and then roll those shells from the loading preparation table to the adjacent loading plate , after rolling on the loading plate, the loading plate will automatically keep consistent with the shooting angle, and then the shell will slide down to the loading port due to gravity, and finally the loading will be completed mechanically.In this way, regardless of the angle of fire, it is easy to carry out rapid loading.

In order to install the modified anti-aircraft gun, a cement cylindrical gun bed must first be set up underground. Most of the gun mounts are housed in this cylinder, and the parts exposed to the ground are equipped with 120mm bulletproof steel plates. The ranging device is completely in accordance with the Type III [-]mm anti-aircraft gun, and is equipped with an independent power generation device.

After more than four months and 24 hours of unremitting efforts, the Osaka Armory Factory delivered the first gun on time, and completed the shooting test on the coast of Hamamatsu under the charge of Osamu Heiyama and Nakamura Nakamura, and collected various shooting elements. During the test, the muzzle velocity reached 930 meters per second, the maximum shooting height reached [-] meters, and the firing speed also reached [-] rounds per minute. It can be said that the Japanese have created a very huge breakthrough in the development of new super-large-caliber anti-aircraft guns. Miracle.

But from another perspective, the Japanese were blown into a rage by the Americans, but in Gao Fei's view, there is no need to make a fuss about the Japanese 150mm anti-aircraft guns. Such anti-aircraft guns can only be installed in concrete fortifications , it is impossible to quickly deploy 2c, and under the heavy bombing of the US military, 2c Japanese output is also a problem. 2c, you must know that this super-large-caliber antiaircraft gun is a manifestation of a country's comprehensive strength. 2c, from metallurgy to optical equipment, auxiliary components And so on.

Therefore, the threat posed by a few anti-aircraft guns is mostly psychological, not substantive. The U.S. military lost hundreds of heavy red bombers and b17d super sky fortress heavy bombers in Europe. The loss can be said to be negligible in comparison.
