However, after discussing with the central government and the United States, Yang Zhenzhen used the reserves in Macao to purchase two additional passenger and two cargo aircraft from the Americans. On this basis, he secretly negotiated with the American Douglas Company and avoided the supervision of the United States with a fund of 150,000 US dollars. In the name of opening the route, all the drawings and manufacturing technology of this aircraft passenger model, DC 4 were purchased.

I have not yet thought of the future development trend of aviation, and the Douglas company, which is extremely despised against the manufacturing capabilities of United Aviation. After the Anti-Union promised not to transfer the drawings of this aircraft to the Soviets, they also readily agreed to sell all the drawings of the DC-4 aircraft.

However, although the contract was reached, Yang Zhen has always been a little uneasy in his heart. At present, the FBI against domestic anti-special forces in the United States is not as large and pervasive as it was a few years later. But at present, the United States, a huge domestic intelligence agency, is expanding quite rapidly.

Moreover, it is currently under the situation of wartime technical control by the United States, and once the Americans find out about this deal, I am afraid that this batch of drawings will be directly detained. Yang Zhen is well aware that the Americans have never been true allies. Everyone knew the purpose of this wartime mutual use, but no one said it.

Once the U.S. intelligence agencies find out about the deal, they will not hesitate to withhold it. After these drawings arrived in the Northeast at the beginning of four or five years, hidden in the equipment transported to the Anti-Japanese Federation, Yang Zhen breathed a sigh of relief in his heart. The drawings arrived at the same time as the three Boeing 307 aircraft and all the drawings of this aircraft.

Yang Zhen does not value the Boeing 307 aircraft, but more importantly, this aircraft, which is the world's first passenger aircraft equipped with a pressurized cabin and can fly at high altitude. Pressurized cabin is still a new technology, and I can't see anything yet, but Yang Zhen clearly knows the role of this technology in civil and military aviation after World War II.

It also happens that Boeing's aircraft is definitely an epoch-making aircraft, because it was born at the wrong time to catch up with World War II, and it can't achieve the sales results that Boeing wants. In addition, Boeing is now fully engaged in the development and production of the B-29 bomber, and has no energy to improve this aircraft.

At this time, Yang Zhen proposed to buy three Boeing 307 passenger planes in Boeing's inventory, and purchased all the drawings and technical data, and Boeing also pushed the boat and sold the three planes, plus all the drawings and materials, to the Anti-Union at a price of 300,000 US dollars.

At least on the surface, the United Nations is still an ally of the United States and not an enemy country, and the sale of this kind of civil aircraft technology to the United Nations is not too much of a violation of the United States' wartime technology control regulations. Speaking of this war, no one knows that it will be fought until the Year of the Monkey. Perhaps by the time the war is over, this aircraft will become obsolete.

Rather than smashing it in your hands, it is better to exchange the technology of this aircraft for some funds and invest in the development of new models. As far as Boeing has information, their main rival, Douglas, is also developing new passenger aircraft. Although the B-29 bomber has made Boeing a lot of profits, who is afraid of less money

In addition, Boeing believes that these Chinese who lack technical support, even if they get the information about this aircraft, it is difficult to produce such an aircraft. Even if you sell the materials to them, you will not create a new opponent for yourself. As soon as the anti-United Nations personnel secretly contacted Boeing, Boeing happily promised to sell all its technology.

However, Boeing offered to sell the drawings of this aircraft, but the Anti-Union had to buy three of the same aircraft that the company had originally produced but had not yet had time to deliver to customers, and because of the outbreak of the Pacific War, the contract was cancelled, and the price was not counter-offered at a price of $300,000.

Boeing's attitude is clear, the pre-war factory price of this aircraft is $310,000. Although these planes have been in the Boeing warehouse for three years, the planes are still brand new. Boeing's price cut and sold to the Chinese almost for nothing, which is already very generous.

For Boeing's request, Yang Zhen also happily agreed. However, Boeing is required to send a few technicians from the Boeing 307 project to assist the Anti-United Nations in developing and manufacturing this civil airliner, and all expenses will be paid by the Chinese side itself. Yang Zhen's request, Boeing also happily agreed.

Three of the four purchased DC-4 aircraft were handed over to the Air Force, which were converted into special aircraft after removing all the seats. The remaining cargo model was left in the northeast and handed over to the Equipment Department, which was specially responsible for the air transportation of large equipment to avoid the leakage of many top-secret things. The three Boeing 307 planes were transferred to the central two, and one was given to the Soviets to pay off their debts.

However, despite the information on the new transport aircraft, only the Soviets, including Yang Zhen, who had been peeping at the B-29 bomber technology for a long time, had not made progress for a long time. Just took advantage of the opportunity of the whole of North Manchuria to control the bombers in their own hands, and got two of these bombers from the bombers that crashed in the war by the Americans, and the Wright R 3350 engines were used.

Although during the U.S. bombing of Japan, the Soviets also sent ships of the Pacific Fleet to cooperate in the rescue of U.S. pilots. Taking advantage of the fact that the Japanese Navy had no time to take care of the defense of the Japanese Coast, they cruised the route of the US bomber group, hoping to get something from the US planes that crashed in the Sea of Japan after the US troops failed to hold out to North Manchuria.

However, under the circumstance that they could not get too close to the Japanese mainland, apart from the crooked and crooked scoop up, many parachuted anti-United Nations and US pilots, they basically found nothing. Once this rather heavy tonnage plane crashed into the sea, it basically sank to the bottom of the sea, leaving few opportunities for the Soviets to do it. The Soviets, who had been working hard for a long time, finally got only one engine transferred by the Anti-Union.

However, on this matter, Yang Zhen did not confide in the Soviets. He got not only these two engines, but also took advantage of the opportunity of the US bomber that was wounded in the sky over the Japanese mainland to crash into North Manchuria. I got a copy of the latest bomber navigation system of the US military, as well as an AN-13 bombing radar and a complete electronic countermeasure system.

And with the increasing number of war-damaged planes of the US military, airborne artillery automatic aiming equipment has been obtained one after another. Although the U.S. military moves quickly, as long as the bomber crashes in the territory of the Anti-Japanese Alliance, it will send people to completely blow it up to avoid technology leakage, and not even a single wreckage will be left. But their actions are no matter how fast they are, where can they catch up with the landlords' anti-union fast?

In particular, several US-made bombers that were forced to land at the anti-United Nations airfield, although the US military wanted to go there at the first time, but they were also touched inside and outside by the anti-United Nations. It is impossible to get a complete plane, and it is still possible to get some of the things you want on the wreckage of American planes all over the eastern part of Heilongjiang.

It was not until the end of 44 that the Anti-Japanese Federation got a forced landing in the Changbai Mountains and because all the crew members died, the Americans never found the U.S. B-29 bomber that seemed to be intact. Satisfied the Soviets, who wanted to get a B-29 bomber.

At the same time that the Anti-Japanese Union and the U.S. military were intensifying their air raids on Japan, the Japanese troops were transferred to the Korean Peninsula and South Manchuria, as well as the bomber air units on the mainland, were constantly adopting the tactics of small formations in an attempt to sneak attack the North Manchurian industrial area and the airfields where the Anti-Japanese Air Forces attacked Japan. In particular, several airfields where the US military was stationed became the target of the Kwantung Army's key care.

At least half of the bomber groups sent by the Japanese army, at least half of the Japanese sneak attack groups, were all coming to these US airfields. For the Japanese, these bombers, with their ultra-long range and bomb load, were too much of a threat to their homeland. Since it can't be solved in the air, then find a way to solve them on the ground.

It's just that the Japanese sneak attack was carried out without fighter escort and under the strict defense of the US military and the Anti-Japanese Alliance, basically they did not even touch the edge of the US airfield. After the US heavy bomber group was stationed in North Manchuria, the Americans were suddenly much more generous in providing radar for the United States.

In particular, the US military has provided the latest SCR 584 air defense radar with performance exceeding the original SCR 602 radar, which has greatly improved the combat capability of mobile air defense against the United Nations. The performance of the SCR207 radar is also far superior to that of the previously provided SCR268 radar. Coupled with the interception of the P61 night fighters, the Japanese army participated in the bomber group, and the losses were unusually heavy.

Whether it is the Type 99 light bomber, the Type 97 and Type 100 bombers, or even the latest Type 4 bomber group, not only is it basically futile, but it also suffers heavy losses under the interception. In particular, most of the bomber groups transferred to South Manchuria were destroyed on airfields on the Liaodong Peninsula before they could be put into service.

The only time it broke into the base area of the Anti-Japanese Union was the Japanese Army Air Force, which took off from the mainland, with a group of 17 Type 100 bombers and 31 Type 4 bombers. Following behind the group of bombers returning from the US army, they tried to use a sneak attack to destroy these US B-29 bombers on the ground.

But he didn't expect that as soon as he entered the base area of the Anti-United Nations, he was discovered by the original 268 radar of the Anti-United Nations. Then it was accurately locked by the SCR 584 radar. Because the Japanese did not know that all the bombers of the Anti-United Nations and the US military were equipped with airborne radar transponders. The sneak bomber group sent by the Japanese army did not have this kind of identification thing at all.

After the bomber groups of the American army began to land one after another, the Japanese bomber group followed behind the butt of the American army. I didn't know that the bombers of the US military and the Anti-Japanese Union were equipped with Japanese bombers that could clearly identify whether the planes in the sky were their own people or the enemy's airborne radar transponders.

Because there was no answer to the ground radar signal, the radar network of the Anti-Japanese Union had already discovered this group of strange visitors as soon as they approached the mouth of the Tumen River from the direction of the Sea of Japan. However, at the request of Chen Long, who was personally sitting at the radar station, he did not issue the alarm prematurely, but waited for the group of Japanese bombers to cross the Tumen River estuary and enter the base area of the Anti-Japanese Union before issuing an alarm to the US troops.

What are you kidding, if this air battle is allowed to fight over the Sea of Japan, how can he have a chance to get even the wreckage of this US fighter jet, and he can complete the mission that No. 1 personally explained. What plane fell into the sea, and what did it do in the absence of divers?

Since the arrival of this US fighter plane in Northeast China, Chen Long and the air force have been planning to find the fighter. It's just that the U.S. military watched too closely, and the opportunity was never found. Although Yang Zhen did not set a deadline, Chen Long, who knew that what No. 1 wanted would definitely not be an ordinary thing, pushed himself very urgently.

He even conceived of looking for an opportunity to send a plane to take advantage of the opportunity of conducting a night patrol with the US military to knock down such a US fighter plane in the name of a collision. In order to get the on-board radar of this aircraft named by No. 1, as well as the piloting device of the aircraft. Chen Long, who pushed himself too quickly, was already somewhat unscrupulous in order to complete the task.
