The machine guns of the half-track suppressed the rapid approach of the enemy troops. The troops quickly moved back through the communication trenches and removed all the weapons they could take, by which time the half-track was piled up with branches and ready to ignite.

These vehicles are inconvenient to maneuver in the valley, so it was a big mistake why Bisheng deployed them here, and Chu Tingchang made a mistake and formed a defensive line that the Japanese army did not expect, and temporarily blocked it, so as to disrupt the enemy's plan to bite the Chinese army by taking advantage of the situation. When the Japanese began to storm the vehicles to form a defensive line, the soldiers on board were able to take machine guns with them and take them with the evacuation vehicles, and when they left, they ignited gasoline. Seventy chariots joined each other end to end and began to burn. Fighter jets flew in the sky, and it was clearly seen that the fire dragon in the valley was blocking the Japanese army. Now the Chinese troops have withdrawn to the last line of defense. They have killed and wounded more than 3,500 enemies, and the main combat strength of the 31st Division has been exhausted. Now it's up to who can make it to the end.

At this time, Chu Tingchang was already on the way back, he didn't know how to tie up this enemy, what he was really worried about was not the enemy in front of him, but the enemy rescue force behind him, at present, the 49th Division that had been killed by Ruokai had no movement at all, and its radio activities could not be heard, and the American and British planes flew over the forest without interruption and did not find any movement, and the Japanese acted strangely, so this must not be regarded as a reassuring signal.

According to Eastern military thought, if the enemy really has no time to rescue, he should use a large number of radio stations to make calls to show the truth, such a mysterious silence, but it makes Chu Tingchang feel like a ghost. He pretends to be a ghost a lot, and everyone has a ghost. As a last resort, he pulled down his old face and asked the United States, Britain, the United States and Britain to immediately drop scouts to ensure the safety of the rear of his troops. In this way, if the enemy approaches from behind, he will at least have time to withdraw his troops. Annihilating the enemy's divisions is not his primary goal, but preserving strength is the primary goal.

Stilwell was also worried about the situation here, and he urgently needed Chu Tingchang's troops to open a counterattack on Burma for him, and he did not want this army to suffer losses.

In principle, it is not feasible to throw American personnel into unknown territory occupied by the enemy, but he must increase the number of Chinese troops at all costs. For political reasons, the Japanese base camp was preparing to launch a landing in Australia, and their navy temporarily abandoned the Bay of Bengal in order to concentrate its transportation capacity and keep the Australian offensive. Because in the eyes of the base camp, Australia's strategic position is more important, and it is much easier to occupy than India in the sea. Their strategy in northern Burma was changed to a delay in increasing the number of troops, and it was expected that the strength would increase to 10 divisions to form a front army to resist the Allied offensive until the end of the war in Australia, and then return to counterattack.

Washington put tremendous pressure on Stilwell to hold back more of the enemy's forces and supplies, which meant that he had to help Chu take the risk. Now that he had gotten out of his way, he immediately set about throwing some American soldiers who had the ability to send reports but had not had time to be trained in jungle warfare into the incomplete northern jungle of Rakhine, which meant that half of these people might not make it out of this primeval jungle alive, but he was too eager to know what was going on.

At the same time, the naval range on the east side of Kagoshima, Kyushu. Makino and Asano sit side by side on the beach and look at the sea. They were able to sit together not because they had reconciled, but because the fifth test of the new weapon presided over by Makino had failed the first four. Makino improved the body of the missile and changed the control method, but he predicted that this command remote-controlled rocket would be difficult to hit the target today, but what he wanted was not achieved overnight.

The sky had already darkened due to the time wasted on the * refilling the launcher. The technicians of the air technology factory suggested that Makino abandon today's experiment and move it to next week, but Makino flatly refused. He ordered the target ship to turn on its lights to increase visibility. He didn't want to waste any more time, because the salvage of Kasugamaru also had to be presided over by him, and the weapons project here had better progress before he left. Unfortunately, there are very few people in the project who can understand his significance for this weapon, and the scholars of the Imperial University are too theoretical, so they have not found anyone who can entrust the work. Asano, of course, was not in his field of vision, because Asano did not possess basic engineering literacy at all.

The rocket to be tested today has already been named the Sakura Bomb, and I don't know who named it at the top, so it seems that even if history changes, there is a part of the same line. It can be seen that above the round * on the launcher, there is a groove, where is the driver's position, although someone driving a suicide bomb was persuaded by Yamamoto to forcibly stop. However, the Navy has reserved space in the pilot's compartment for the batch of * that is being streamlined so that Makino's plan fails so that he can continue to engage in suicide weapons.

According to his idea, the practical stage of this * is to use the new radar to detect sea targets and fly to the target through command control. The second stage is to be able to launch from the air and detect targets farther away by the radar mounted by the aircraft, which crosses the curvature of the earth.

The Navy had just used captured British radars to develop a similar meter-wave radar, but the base camp had made a move to develop a multi-purpose teleprobe that could not only measure the angle of the sea, but also measure the direction of the air, and preferably could also carry out communications. Makino proposed that different types of radars must be separated, and that these functions cannot be completed by a 1.2-meter wavelength radar, but the navy also feels that warships have too many strange-shaped antennas on top of them, so they cannot install huge optical rangefinders, and the center of gravity is shifted upward, which will affect the resilience of the ship.

So what he is experimenting with today is still a kind of rocket that is optically aimed and controlled by manual commands. In fact, from the perspective of the 21st century, the progress of the work he presided over is amazing, the first bomb exploded on the launch frame, the second flew in the air and fell not far from the console, and the third was able to fly one kilometer in the direction of the target along the measurement angle and fall into the sea; The fourth extended this distance to 6 km. The target 12 kilometers away is actually not far away. But the navy was still not satisfied with the speed, they could always find volunteers to drive this kind of thing into the enemy, Yamamoto was already forced to vomit blood by the hostility of Australia, and he desperately needed a new weapon to destroy the American fleet once and for all.

"You've tried this thing so many times, why is it still like this bear? How can you refuel for so long? Asano said impatiently.

"You don't know anything about engineering, it's not a real combat weapon, it's an engineering sample that needs to be continuously improved. If it weren't for such a large notch in the projectile body, the center of gravity would be much simpler. Progress doesn't drag on forever. ”

"I really don't understand what the hell you're doing?" Asano criticized unceremoniously, "Since there is still a need for human exercises, why not let the navy design them as suicide planes, which can be driven directly by soldiers to the target, and they can be immediately put into actual combat." ”

"Then Japan will still be defeated, I want a mature missile body that can be effectively controlled, even if optical tracking is still required, but as long as the autopilot and command control systems are mature, it will be very convenient to integrate radar through the central processing unit in the future."

Asano shook his head to show that he didn't understand what he was saying.

On the coast, someone waved his hat at Makino and signaled that the refueling was complete.

Makino picked up a telescope to observe the target ship in the distance, which was a British gunboat Haiyan captured from Shanghai, and the navy decided to use it as a target ship because it could not be repaired once it hit the reef. It was parked 12 kilometers away, and the lights were turned on so that the fire control personnel could find it.

Personnel near the launch frame began to evacuate, the launch console 50 meters behind began pre-launch preparations, and the launch command was transmitted by cable. The entire control group consisted of four people, and since the radio altimeter was still on the design drawings, the flight altitude also needed to be controlled by a handwheel.

The firing principle is a three-point method, and the aiming system, * and the target are always in a straight line until they hit the target. Observation is carried out by a 25x optical goniometer. The shooter needs to constantly operate the handwheel so that the * remains in the center position. To complete the control, the requirements for the control hand are extremely high, and a slightly larger action will lead to * flying or directly planted in the sea. Reliable radar also needs to wait for the mass production of magnetrons, which is currently the most critical of all shortcomings. Even if Kasuga Maru is salvaged, it will not be able to make up for this lesson, so it is necessary to rely on Japan, which is a third-rate technological country at this time, to overcome this hurdle on its own.

Asano smoked disappreciatively, completely ignoring the strict ban on smoking within a one-kilometer radius of the place. Makino ignored him and gave the order for the experiment, and the fat rocket suddenly ignited, slashed across the launch stand, and flew into the sky. In order not to repeat the mistakes of the past, he redesigned the launch scheme. In the initial stage, * lifts off to an altitude of 200 to 500 meters, and the tracking personnel can maintain an angle alignment, and after calculating the distance of more than half of the distance, they will descend to the altitude and seek to hit the target cross-section. Although it is still a human exercise, the rudiments of radar command control in the future are the same. Kasugamaru, a large number of 4 to 16-bit CPUs packed with waterproof, can scoop up about 1,200 tablets, and after simple programming, he can integrate the technology that he has been cobbling together over the years. Of course, with the lowest threshold, he needed a flying machine that could be stabilized laterally. Because simple programming is not possible to solve complex flight control problems.

The rocket flies towards the target, and a member of the fire control team keeps reading a countdown time to remind the operator when to lower the altitude. This rocket can maintain a relatively stable flight at an altitude of 150 meters, but at an altitude of 150 meters, it will inevitably fly over the target, so it can only reduce the altitude to less than 20 meters in the final stage, which requires the work of the operator. The operators did not have a simulator to train repeatedly, and were constantly told by their superiors that each shot failure meant 300,000 yen in vain. The psychological pressure can be imagined.

Seeing that the tail flame was getting lower and lower, almost touching the surface of the water, Makino's heart also reached his throat, he knew that at such a height, whether it was optical observation or command accuracy, it was difficult to control it finely, and it could hit the sea at any time.

A ball of flame rose on the target ship, * not carrying a counterweight, but directly carrying a 600-kilogram charge warhead, which the Navy meant, in order to save time to synchronize the experimental armor-piercing fuse.

Makino stood up suddenly, and he almost couldn't grasp his glasses in his hands in excitement. He watched as the 1,200-ton British battleship began to burn from the middle and sank rapidly.
