However, after razing Kobe and Nagoya to the ground and completely destroying the poison gas warfare base of Okunoshima, it does not mean that the bombing intensity of the Anti-United Nations will be reduced. The military factories in these places, as well as the chemical warfare production bases, are only the first targets of the Anti-United Nations.

What Yang Zhen wants to do is not only to defeat the Japanese on the battlefield, but also to completely destroy the Japanese mentally and willfully. After a break and a certain summary and adjustment of tactics, the air raids were suspended for a while. When the time entered the fourth or third year, the anti-coalition bomb extended warm holiday greetings to the residents of the entire four islands of Japan.

The New Year of 1943 for the Japanese in the Tokyo metropolitan area began with a large-scale air raid by the Anti-Japanese Union. At 3 a.m. on 1 December 1942, 200 Stirling bombers and 100 70 B24 bombers, with the cooperation of electronic warfare planes, appeared on time over Tokyo, Japan. All the more than 600 tons of American-made napalm carried were dumped in the urban area of Tokyo.

In addition to providing bombers, the Americans also provided a large number of semi-finished products of American-made napalm. The power of the napalm developed by these Americans themselves slightly exceeded that of similar products developed by the Anti-Japanese Federation itself. After completing the assembly in the rear factory, Yang Zhen did not hesitate to use it directly on the heads of the Japanese.

With the successive arrival of American and British bombers and the increasing number of aircrews trained in an assembly line posture, the forces that the Anti-United Nations can devote to bombing Japan are also increasing. The Americans were picky about the aid of equipment and industrial equipment, but they were quite generous in terms of the materials needed for the bombing of Japan by the Anti-Japanese Union. The generosity of the British is not inferior to that of the Americans.

Not only was it quite generous in the amount of heavy bomber assistance, but at its peak it was given 200 planes a month. Fuel, semi-finished bomb products, aircraft parts and other needs, but also quite generous. The amount of high-quality aviation fuel that the Anti-Union could not produce at the time of its own even exceeded the amount given to the Soviet Union.

By the end of the fourth or third year, the number of heavy bombers of the Anti-United Nations has always remained at a scale of more than 500 that can be dispatched at any time. A large number of B-24 bombers and Stirling bombers dropped hundreds of tons of high-explosive bombs and napalm on the Japanese mainland.

Even in the past four or four years, the Anti-Japanese Union had dispatched thousands of Stirling, B24 bombers, B17 bombers, and a large number of other bombers in the midst of many bombings. With the cooperation of a large number of electronic warfare aircraft, the strategic bombing of Tokyo lasted for a whole day. More than 3,000 tons of bombs were dropped in a single day in the city of Tokyo, and almost the entire city of Tokyo was completely destroyed.

As the Anti-Japanese Union bombed the Japanese mainland more and more vigorously, the strength of the Japanese army aviation was constantly weakened from the front line. Not only could the war-damaged planes not be replaced, but in order to increase the air defense capability of the homeland, the Japanese could only continue to transfer combat aircraft from the northeast to Korea and the mainland.

In order to ensure the security of the homeland, the Japanese army aviation mobilized a large number of troops and set up three interception lines along the coast of the Sea of Japan, namely Korea and Honshu. Attempts were made to intercept the anti-United Nations bomber group over the Sea of Japan in order to reduce the air threat to the mainland as much as possible.

However, the construction of these three air interception lines was not an easy task for the Japanese. Faced with an area of more than one million square kilometers, more than 2,300 kilometers wide from north to south, and 1,300 kilometers from east to west, it is conceivable that the manpower and material resources required to mobilize can be imagined.

It is important to know that the Japanese archipelago, which is more than 1,200 kilometers long from north to south, three of the four main islands, Hokkaido, Honshu, and Kyushu, and almost all of the western part are along the coast of the Sea of Japan. The vast Sea of Japan has almost all become a passage for the anti-United Nations bomber group to enter and exit.

There are basically no large islands in the sea, so it is impossible to set up an outpost. Even the number of small islands is not large, mainly concentrated in the Sea of Japan around North Korea and the Japanese mainland, so that the Anti-Japanese Union does not have to deliberately choose the route. As long as you are as far away from the southern part of the Korean Peninsula as possible.

Dokdo, Ulleungdo, and Oki Islands, which are controlled by the Japanese at sea, are also key areas to be guarded by the Anti-Japanese Union. The Japanese wanted to set up radar stations on these islands, but they were bombed again before they could be repaired. Blow it up and repair it, repair it and blow it up again. These radar stations were not repaired from the time the Japanese started to build them until the end of the war, and they did not play the role that the Japanese expected them to play.

The Japanese, who had no choice but to set up the radar station on the coastal line, retreated. The Japanese have built several large radar stations along the Sea of Japan along the mainland and the southern part of the Korean Peninsula to provide the vast amount of information they need. A large number of light ships were deployed in the Sea of Japan as anti-aircraft alert ships.

However, the development of radar technology in the Japanese was slow, the level was backward, and the most important thing was that it was bulky and scary, and the so-called warning boats converted from trawlers could not be installed at all. Although the number of vigilance boats deployed is large, the means of observation are still mainly telescopes and listening tubes.

Under the communication interference of the Anti-United Nations, even if these alert boats captured the bomber group of the Anti-United Nations, they could not transmit the news back to the mainland in the first place. In addition, every time the Anti-Japanese Union dispatches a bomber group, there will be Il-4 or DB-3 bombers to clean up these warning boats. Although the Japanese army deployed a large number of warning boats in the Sea of Japan, they were of limited use.

In any case, under the circumstance that the Anti-Japanese Union never bombed its own sphere of influence, the Japanese Navy transferred large and medium-sized ships from the Pacific Theater back to take on the task of defending the Japanese defense and alert ships. Moreover, the U.S. military's counterattack is getting bigger and bigger, and the navy, which itself feels that there is not enough ships, is really unable to send too many ships back to the mainland for reinforcements.

The only marked support of the navy was to send the newly commissioned super battleship Musashi, together with the battle cruiser Kongo, to run to the anti-United Nations radar station in Hunchun at the mouth of the Tumen River, escorted by two heavy cruisers and more than a dozen destroyers, and fired more than 600 rounds of 460-millimeter naval artillery shells in one go.

With the exception of a few small hills, the shelling, which had largely no effect, was the only actual support operation for the Navy. Under the siege of dozens of Blenheim light bomber planes dispatched by the Anti-Japanese Union, they were subjected to more than a dozen innocuous rockets, as well as two aviation close-in bombs, and one destroyer was damaged. The Navy immediately withdrew all ships, in the absence of a single similar operation.

In desperation, the Japanese Army wanted to completely block the path of the bomber group of the Anti-Japanese Union to break through into the Japanese mainland, and the Japanese army could only find a way to transfer a large number of air forces. In order to construct these three interception lines, the Japanese Army Air Force transferred a large number of fighter planes back to the mainland and in Korea.

Under such a situation, the tremendous pressure on the fighter units of the air force, which lacked fighters with sufficient air superiority capabilities, was temporarily relieved to a certain extent by the beginning of the fourth or third year. The fighter unit, which was very embarrassed by the new Japanese fighters, could finally breathe a sigh of relief.

Shortly after the bombardment in early October, we faced a devastated homeland. In order to ensure the security of the homeland, the Japanese Army had to withdraw all Type II fighters to the mainland to serve as air defense missions. At the same time, the strength and speed of the Kwantung Army's replenishment of battle-damaged aircraft were also declining.

For the Japanese, it is not only the bombing of the mainland by the Anti-Japanese Union that annoys them, but also the losses caused to the local military industry by adopting the tactics of drawing wages from the bottom of the kettle. By constantly igniting one Japanese city after another, it dealt a serious blow to the morale of the people who kept the war going.

What made the Japanese even more speechless was that the bombing of the Anti-Japanese Union was not only continuing in the cities, but also in the countryside. Planes were constantly being dispatched to drop a large number of mines on Japan's railroad and highway systems, and even on the ruins of cities that had been bombed by them.

And these mines, all of them are made of wooden shells. Where it is thrown, it will be painted with a protective color depending on the season and the local environment. Moreover, in the processing of its appearance, a certain amount of camouflage has been made. When the sappers were removed, not only was it unusually slow, but they also suffered heavy losses from the bombing.

What makes the Japanese grit their teeth the most is that the anti-union throwing such hard-to-eliminate wooden-shell mines is not limited to the communication lines and factory areas. Even in the main grain-producing areas of the Japanese mainland, large-scale mines painted green or yellowish in color were thrown.

These mines, disguised in the form of a clod of earth, a can, and even a part, caused the Japanese endless trouble than the Great Bombing. Because of the large number and wide distribution of these mines, even if the Japanese mobilized all the sappers, they could not remove these mines in a short time. What's more, many times, sappers can't tell what these mines look like.

Of course, if the Japanese have patience, it is not impossible to let these airdropped mines stay there. These mines are all wooden, and they are specially designed, and they all have a certain shelf life. If it rains, it will detonate in heavy rain. When there is a continuous light rain, the rain can also cause the mine to fail.

It is also easy to be damaged by rodents or ants. Of course, if the Japanese are unlucky, just in time for a year of drought, or if the rats have been wiped out, then don't blame them. After all, it is not an easy task to design the service life of weapons.

It is not easy to design the service life as long as possible, and there are many disciplines involved. However, consciously designing the life span to be shorter, while still ensuring the power, is not an easy task. You must know that even wooden mines, if good wood is used and a certain process is adopted, it is no problem to maintain the life span of several decades.

As for why these mines are not designed to last long, the reason is simple. Yang Zhen didn't want one day when his troops set foot on the Japanese mainland, they would step on the mines he had planted. A year is the best, a little more he doesn't care. But as long as it doesn't expire in three or two days, he doesn't care.

These mines are manufactured from military factories for weapons and equipment, especially for the production of butts and for the manufacture of aircraft scraps. Moreover, most of these mines are made by military factory workers in their spare time as a pastime. Neither Lang costs too many raw materials other than explosives, nor does Lang spend many man-hours.

The structure and sealing method of the thunder body were proposed by a carpenter who worked in an aircraft factory and once built pillars in the temple. As for the explosives, they were all dismantled unexploded bombs dropped by the Japanese, as well as expiring shells. It's just that the fuse is a little more troublesome, but it's not too troublesome. After all, the arsenal of the Anti-Japanese Union manufactures all kinds of mine fuses, and practice makes perfect, even more proficient than making bullets.

The only trouble was that in order to make a deceleration parachute, there were no handkerchiefs and umbrellas in the base area for a long time. In the case of limited parachutes, towels and other items were used instead. Without any complicated technology, all the housewives in the base area can be mobilized to participate, and millions of ultra-small parachutes can be produced every year.
