Tokyo, U.S. Far Eastern Intelligence Command.

"It has been 29 hours since the first B-72 was shot down from high altitude. Can you give me a clear analysis report?" Weiland asked Charles Willoughby.

"I can tell you what shot down the B-29, but the performance of the weapon that shot it down... can only give you some clues."

Charles Willoughby opened the report in his hand, which had just been completed half an hour ago.

"First of all, please look at this thing." Charles Willoughby took out an aerial photo and nailed it to the wall. "This is a photo of a place in Pyongyang taken by the Air Force's reconnaissance plane on September 9."

"This is a partial enlargement of the photo. The Analysis Department of the Ministry of Intelligence has helped you to boldly mark the artificial traces in it."

Partially enlarged photos, four five-pointed star shapes connected by roads, covered with green nets, but you can still see a little difference from the surrounding environment when you look closely, and it becomes clearer when you outline it with red lines.The four five-pointed stars are wrapped together by two other figure-eight roads to form a complete geometric figure.

"And then here's another photo," said Charles Willoughby. "This is a photo of the Moscow area that I requested from European Intelligence Command."

"NATO has signed secret agreements with many civil aviation companies. Civil aviation companies will hide cameras in certain parts of passenger planes flying to the Soviet Union and Eastern Europe, and take pictures along the way. This photo is a Lufthansa flight flying to the Soviet Union. At that time, the photos of the forests outside Moscow were taken. Similarly, the facilities in these forests have also been camouflaged, but the intelligence agencies in Europe have also enlarged and outlined parts.”

The mysterious facility on the outskirts of Moscow occupies a much larger area than Pyongyang. It is located in forests and open spaces outside the forest, stretching for more than three kilometers.However, on closer inspection, the basic elements of these patterns are still the five-pointed star shape connected by roads.It's just... There are a total of 12 such five-pointed stars, which are sparsely distributed in a rectangular area that is three kilometers long and one kilometer wide.

"This is a surface-to-air missile developed by the Third Special Bureau of the Soviet Union. The project code name is 'Golden Eagle'." Charles Willoughby concluded.

"B-29 reconnaissance type? B-29 reconnaissance type! Is the front confirmed?" Hearing the news that the fifth B-29 was shot down, Tang Hua's reaction was much more exciting than the previous day's four consecutive bombings.

"In the telegram... there is no detailed reason for the judgment." The Air Force staff said, "However, if the B-29 is bombed with bombs, the flying altitude will generally not exceed 8000 meters. The B-9000 flying at an altitude of 29 meters is already close to the maximum altitude. Generally, it is a reconnaissance model without ammunition."

"Comrade staff, please wait a moment."

Tang Hua took the letterhead.

"If it is the reconnaissance type RB-29 of the B-29, then searching for the wreckage of the aircraft will reveal a lot of valuable things," Tang Hua explained to Su Yu while writing a telegram, "the reconnaissance type has optical and electronic reconnaissance equipment The optical camera equipment can be used for our research and imitation; the electronic reconnaissance equipment can be brought back for detailed study to find out their reconnaissance equipment's listening capabilities and listening frequency bands, so that our army can take corresponding countermeasures. If the reconnaissance type is still Taking into account the electronic jamming machine - although not sure if all the B-29 reconnaissance models are like this, but I guess a large part is, then even their electronic jamming system can be obtained together, and then we can conduct research..."

After Tang Hua finished writing the telegram, the staff took it away and sent it to Shenyang through the telegraph line of the Military Commission, where Air Force Commander Liu Yelou was there.

After thinking about it, Tang Hua was still sitting in front of the communication computer and wanted to use the dedicated line to send another message to Zhisi.

"The B-29 shot down in the direction of Pyongyang this morning, according to the confirmation of the comrades in the Pyongyang Liaison Office, should be a B-29 reconnaissance type. The reconnaissance type of the US B-29 bomber is equipped with a large number of reconnaissance and intelligence equipment, and may also be equipped with high-power jamming If we can collect these devices from the wreckage, it will be of great help to our future ground-air combat and electronic countermeasures. If the North Korean comrades agree, we also hope to search the fallen B-29 reconnaissance wreckage in detail as soon as possible, and find Take out all electrical, radio components and suspicious parts on the plane, so that we can conduct research and analysis immediately."

After confirming that Zhisi had received the news, Tang Hua relaxed.

The Tu-10 of the 2th Division of the Air Force fell on Yamato Island. After the ground troops of our army attacked the island, Mao did not see it. Only a large pit with scorched soil was found near the beach. The Americans and South Koreans even dropped it. The screws were all picked up.

If the communication with the North Korean side is completed and they agree to collect the wreckage of the B-29 for us to analyze, then from today onwards, soldiers from the Korean People’s Army and the Volunteer Army will also pick up parts at the crash site with hundreds of people sticking their buttocks...

……

"So, what your Far East Intelligence Command can confirm is that the Chinese army deployed the 'Golden Eagle' system purchased from the Soviet Union in North Korea?" Weiland asked.

Charles Willoughby: "One hundred percent sure."

Weiland: "How do we restrain it? How far and how high can its missiles hit? How does it work? How powerful is it?"

查尔斯·威洛比：“欧洲情报司令部此前获得的信息，是它采用雷达跟踪和无线电指令制导……欧洲情报司令部获得的最详细的报告是在1949年底，这时候‘金雕’项目刚刚启动。不过好在你们被击落的7架飞机为我们提供了至关重要的直接证据。导弹的最大飞行速度大约为2.5倍音速，10月16日下午的导弹攻击，被击落的B-29距离发射阵地距离在25到31公里，10月17日中午在长丰被击落的2架B-29，距离发射阵地22公里。10月17日晨的导弹攻击，被击落的RB-29飞行高度在9100米。我们的估计是，这种导弹的最远射程在35到40公里，最大作战高度则可能远远大于9100米……因为这种导弹很可能是苏联为了针对升限13700米的B-36轰炸机而设计的，并考虑到要能拦截即将出现的飞得更高的喷气式轰炸机。”

Wayland: ...

Only a week after he took office, he felt that his heartbeat was already arrhythmia.

After receiving the combat plan and proposal from the staff, Weiland considered for a long time, and finally temporarily gave up the idea of ​​challenging the Chinese army's upgraded anti-aircraft missile system, but first tested the improved guided bomb.

The B-29 flies high, is immune to anti-aircraft missiles, and has a rough skin and thick flesh. In the past, a B-29 was almost directly hit by an 85mm shell, and an engine failed. The B-29 just dropped the bomb in advance. Go down, turn around and return after losing weight.It is relatively safe to use this as a test. It does not require pilots to test the capabilities of Chinese air defense missiles with their lives.

Thinking about it now, Weiland felt really stupid.If the new anti-aircraft missile jammer is tested, even if it fails, it will only lose two small aircraft and two pilots.As a result, I wanted to take the B-2 out for testing. There were 29 pilots on the 7 B-29s.

"The Ordnance Department and the Electronic Warfare Laboratory need to study ways to interfere with the 'Golden Eagle' anti-aircraft missiles. We ask the Intelligence Command to send intelligence officers to assist from tomorrow."

Weyland said his last words and left the Intelligence Command office.

"Bring out the glider-guided bomb plan again. In addition, does the Air Force have a rocket-propelled air-to-ship bomb?" Back at the headquarters, Weiland called another staff officer and asked about this matter.

Chapter 190, Daily battles in positional warfare

"Ambassador Roshin, General Krasovsky, Military Attache Kotov."

The Prime Minister, Nie Shuai, Tang Hua, and Bo Gu sat down. Sitting in the meeting room were the Soviet ambassador Roshin, the head of the Soviet military advisory group, General Krasovsky, the military attache and deputy head of the military advisory group, Kotov, translate.

After the War to Resist U.S. Aggression and Aid Korea began, the Soviet Union established a permanent military general advisory group in China, leading Soviet advisers and experts in various headquarters, military branches, major military regions, and military academies in China.The largest number of Soviet military advisers was in the Air Force. Soviet technical experts and instructors participated in a complete set of education work from the formation of aviation schools to the reception of fighter jets, familiarization with equipment, and the organization of air battles.So the head of the regiment, Krasovsky, came from the Soviet Air Force.There are also Soviet military advisers in other arms and headquarters of our army, most of which are related to the introduction of Soviet-aided equipment.

The two sides had a routine work exchange first, mainly talking about the situation that the Volunteer Army Air Force, under the leadership of Soviet Air Force pilots, tried to go out of the country and enter the airspace over North Korea in the past six months. Krasovsky praised the volunteer pilots for their fighting courage and strong learning ability , The progress is rapid, but the jet fighter air combat, especially the essence of air combat in large formations is not enough, need to continue to learn.The chairman and Nie Shuai agreed with the opinions of the military advisory group, but also reminded the Soviet side to finalize the plan to replace the MiG-15 with the MiG-15bis as soon as possible.

"First of all, I suggest that everyone present at the meeting celebrate the achievements of the S-25 missile system in North Korea last week." It was Tang Hua's turn to speak, and he attended the meeting today mainly because of the S-25. "Three engagements and shooting down all 7 B-29 bombers that entered the defense zone. The interception rate of the air defense system is 100%, and the hit rate of single-shot missiles is 65%. This is completely worthy of congratulations. The actual combat success of the S-25 in North Korea, It has proved the excellent efficiency and technological leadership of this air defense system, and it will be difficult for the U.S. Air Force's heavy bomber nuclear raid tactics to pose a threat to Moscow and major cities in the Soviet Union in the future."

Tang Hua's opening made the four representatives of the Soviet Union nod and smile.Indeed, the S-25's first successful battle last week is great news, and the top Soviet leaders, including Comrade Stalin, are very satisfied.The atmosphere of the meeting was also more relaxed.

"As a person who has developed China's Hongqi-1 air defense missile and has also participated in the development of the S-25 air defense missile, I would like to submit to you a proposal for urgent improvement of the S-25 missile system. During the period, the improvement and modification of the 4 sets of S-25 air defense missile systems deployed by North Korea will be completed, including the missile control system, radio transmission system and command receiving system on the missile. We have prepared the new radio transmission system and missile modification kit It can be shipped to North Korea at any time. Of course, I have also prepared the modification kit for Moscow’s S-25 system. I hope you will inform the Korean People’s Army comrades who operate the missile system as soon as possible, so that the improvement project can be started as soon as possible.”

Krasovsky: "The S-25 missile system now rules the skies of North Korea...the skies of North Korea within a radius of 40 kilometers. Not only the North Korean comrades, but also the Soviet General Staff are extremely satisfied with its combat capabilities. Of course , Academician Tang’s improvement plan should be able to improve the performance of the missile system again, but I think this matter can go through the procedure first, be included in the defense budget of the Soviet Ministry of Defense for the year, and then proceed step by step.”

Tang Hua: "General Krasovs, according to the conventional equipment ordering procedures, this should be the case. But there is one difference. The Soviet Union is now in peacetime, while North Korea and the Chinese People's Volunteers in North Korea are in a state of war with the United Nations. All improvements should therefore be made as soon as possible.”

Kotov: "According to common sense, even according to the worst scenario, it will take several months for the United States to bypass the S-25 missile system."

Tang Hua: "You may be saying that from May to the beginning of October, it took the United States about five months to find a way to restrain the HQ-5 air defense missile. But the problem now lies in this. The Korean War made the weapons and equipment of both sides especially The update and iteration speed of electronic equipment has been accelerated. In order to regain the advantage on the battlefield, the U.S. Air Force and the scientific research department behind it have increased the work efficiency to the extreme..."

"This has to start with the ground-to-air confrontation of the Hongqi-1 air defense missile." Tang Hua changed his sitting position and continued, "The news feedback from the North Korean front may be a little behind. Let me tell you the latest situation. The Americans used four Over the past few months, we have developed jammers in four frequency bands for Hongqi-1 air defense missiles, which were put into use on October 10. Then we activated the other four spare frequency bands for Hongqi-5 missiles. We won again in the war of confrontation. Since then, the air over the Korean Peninsula has returned to calm, and the United Nations has not used large-scale tactical aircraft to attack again. However, from October 1 to the present, our front-line electronic interception troops have received interference from US aircraft twice. Radio waves, in fact, the U.S. military has refurbished their jammers in more than a week, and now they can interfere with the 4 frequency bands of the Hongqi-10 air defense missile. It is only due to some special reasons that the U.S. military did not test our air defense missile system again .”

"As a response, we have upgraded the Hongqi-1 missile system deployed in North Korea. The upgraded air defense system is named Hongqi-1A, which can bypass the new jamming aircraft of the US military. You should have understood, Hongqi -1 and S-25 missile systems have a similar guidance pattern. So how the US Air Force has various countermeasures against the HQ-1, it can also use the same method against the S-25. And the S-25 I proposed The improvement proposal for the missile system is to raise its technical level to a level comparable to that of the HQ-1A."

"Any kind of weapon has a way to restrain it, and Hongqi-1 and S-25 are no exception. Only by constantly evolving in the field of technology, and even being one step ahead of the enemy to prepare for new iterations of technology, can we maintain an advantage on the battlefield."

"If the S-25 system deployed by the Soviet army in Moscow is temporarily difficult to be approved for upgrade, then the S-25 system deployed by North Korea should also be approved as a priority. I have prepared the radio transmission system modification kit. In addition, North Korean comrades, Soviet advisers and Our skilled workers set up an ordnance modification workshop in North Korea to replace some of the S-25 missile parts." Tang Hua finally said.

Krasovsky: "... what happens if the upgrade of the S-25 system is slow?"

Tang Hua: "The S-25 system in Moscow will not have any serious consequences. After all, the United States and the Soviet Union will not immediately have a large-scale war... But if the US military has mastered the technology to interfere with the S-25, it may be used immediately in North Korea. The new jamming device is used as support to launch an air-to-ground strike, and a part of the S-25 missile system may be destroyed, resulting in casualties and very serious equipment damage.”

Shenyang Arsenal has now become a branch factory of Dalian Jianxin Company. The factory area in Dalian was too crowded, so part of the production line of guns was moved to Shenyang.By the end of 1951, the transferred production line included Type 3 mortars and ammunition, among other oddball weapons items.

"Ready, launch!" On a GAZ truck, the operator next to the driver heard the voice on the walkie-talkie and pressed a button on the front operation panel.

Several oblique cylinders on the truck body "bang bang bang", and at the same time as green smoke was emitted, several objects were shot into the air more than 100 meters.

After reaching the highest point, these small objects open a parachute and emit a very bright red light at the same time.The parachute carries small objects down slowly at a speed of 3-4 m/s. In the eyes of ground GAZ truck drivers and operators, the red light of these small objects is particularly dazzling. When they are about to fall to the ground, the drivers can feel Feel the warmth and heat brought by the red light.

After more than 30 seconds, the small object and the parachute fell to the ground. Three small objects went out immediately, and one small object went out later. The red light ignited the parachute. Run forward and extinguish the parachute fire.
