Back to the Republic of China to be a editor

Tang Hua: "The test of the radar also depends on whether its image fits the real target position, whether there is any misalignment, or whether there is image distortion. This is related to whether the missile can be bound with the correct target parameters. We will conduct many tests in the future. , just to measure this. Lao Jiang, you didn’t bring a measuring tool on the plane today, so let’s leave it at that, and fly back.”

After about an hour, Tu-2 returned to the airport and landed.Chang Qiankun jumped off the plane, "Not bad, not bad. Although according to the test process, the first-level test should be done, the second-level test was also tested today. And it went smoothly."

Tang Hua walked over and laughed, "Minister Chang, this is too full of words. Look back."

Chang Qiankun looked back and saw that the radome of the landed Tu-2 was cracked with a one-meter-long crack, and the whitish glass crack was very conspicuous on the black-bottomed radome.

……

"I just said that this problem is not complicated." Xiao Shaoqing said in the hangar with a sigh of relief, "The root of the crack in the radome starts from the position of the nut, and the other parts of the radome have no problems, indicating that the position of the screw hole is damaged. The integrity of the radome has been compromised, and a weak point has emerged. It is fine when the vibration is not large during take-off, but the aircraft vibrates a lot during landing, and a crack occurs. If the cause of the fault is found, it is easy to solve, and it is enough to strengthen that part. "

On the third day after the first flight, the improved version of the radome was ready, and the above Tu-2 prototype was installed - it may be called Tu-2D.

This time the takeoff and landing were all normal, and the radome was safe and sound.

During the test flight, Chang Qiankun and Xiao Shaoqing were still present, and the plane landed 10 minutes after takeoff. When Tu-2 was taxiing on the runway, a jeep from the Air Force Communications Battalion came in from outside the air force base and delivered a telegram to Chang Qiankun.

After reading the telegram, Chang Qiankun frowned, and then cursed harshly.

Tang Hua: "What's the situation?"

"The Volunteer Air Force bombed Yamato Island a few days ago, and the plane dropped." Chang Qiankun turned his head, "A Tu-2 special bomber went down. Those daredevils from the 10th Air Division!"

Chapter 172, don't worry too much about the leak of guided bombs

In 1951, the Volunteer Army had been planning to take down several small islands on the west side of the Korean Peninsula close to our land.

This series of small islands includes Dajiaji Island, Xiaojiaji Island, Butterfly Island, Lime Island, Kowa Island, and Yamato Island, of which Yamato Island is the largest island.The United Nations Army stationed a South Korean infantry battalion and a South Korean coastal infantry company here, with a total strength of about 1200 people. However, the most important stationed unit on Yamato Island is the intelligence station set up here by the US Far East Intelligence Command. There is a remote Search radar, a radio detection center, and an agent dispatch staging post.

Yamato Island goes deep into the Yellow Sea and is very far north. Calculated from the map, it is higher than the latitude of Pyongyang, and it is almost close to the mouth of the Yalu River. Therefore, the US intelligence station on Yamato Island made the volunteers very uncomfortable.As soon as the Soviet Air Force and the Volunteer Air Force take off from Andong, they can be seen by the radar on Yamato Island. When entering North Korea to fight, the US fighter jets can be arranged in advance to wait for the Chinese and Soviet fighter jets to come up. The radio detection center can sometimes eavesdrop. Call to pilot and base.

The Volunteer Army Air Force is now able to fight evenly with the US military in the airspace from Andong to Qingchuan River, and they dare not fly any farther away.But Zhisi requested that in the future, our side should form air superiority from Anton to Qingchuan River, and from Qingchuan River to Pyongyang, our side should be able to alternately compete with the U.S. military for air supremacy.To achieve this goal, we must first pull out these few nails that are attached to our coastline.

On June 6, the U.S. military launched a large-scale attack on the front line of Dongduchuan, and on the same day, the Volunteer Army’s combat plan to capture Yamato Island was launched.

On the night of June 6, the Volunteer Air Force bombed Yamato Island for the first time. Nine Tu-19 ordinary bombers attacked under the protection of MiG-9, dropping more than 2 tons of bombs. On the night of June 15th, the Volunteer Air Force bombed Yamato Island for the second time, still with 20 Tu-6s.On the same night, the Volunteers and the Korean People's Army captured Lime Island and Butterfly Island.Both bombings accurately covered the targets on Yamato Island, killing more than 25 South Korean troops and destroying a large number of defensive positions and houses.

On June 6, the Volunteer Air Force conducted the third and final bombing before the amphibious attack on Yamato Island.

The first two bombings of Tu-2 were dispatched at night, and the third bombing was dispatched during the day.

因为这次轰炸要精确拔掉南朝鲜军抵抗登陆的关键装备——海岸炮兵连，因此志愿军空10师出动了6架图-2普通型轰炸机和4架使用无线电制导炸弹的图-2特种轰炸机。

6月30日晨，志愿军空军的10架图-2和16架拉-11（负责用机炮扫地）先升空飞往大和岛，20架米格-15稍晚一点起飞。结果米格-15在编队指挥机的带领下跑错地方偏离了集结地域，轰炸机编队没看到护航的米格15，就单独闯进了大和岛上空。

Yamato Island has US military intelligence stations and radars to provide early warning. Of course, the bombers of the Volunteer Army were intercepted by more than a dozen US F-86s.The bomber brigade of the 10th Division of the Air Force charged directly. It was originally planned to use machine guns to straf the La-11 propeller fighter jets of the South Korean Army at low altitude, and rushed forward to fight the F-86 in air combat.

轰炸机硬冲还真是效果不错，4架特种轰炸机两轮制导炸弹投下去，南朝鲜军的6个海岸炮台被日翻了5个。但美军的F-86对图-2机群发起反复攻击，导致志愿军损失很大，10架图-2被击落4架，其中包括3架图-2普通型和1架图-2特种轰炸机。此外拉-11也被击落4架。唯一的心理安慰是空战中志愿军的拉-11击落了1架F-86，创造了我军用螺旋桨战斗击落喷气式战斗机的记录。

"Is your 2nd division all a bunch of road idiots? It's okay for the team leader to be a road idiot, and none of the pilots below know how to read directions and navigate?"

The Air Force’s bombing of Yamato Island and its affiliated islands made such a serious mistake. Air Force Commander Liu Yelou flew directly from Beijing to Andong, where he was furious at the combat headquarters in Andong.

"The flight path deviates by 17 degrees, 17 degrees! I don't use the radio direction finding anymore, use the compass, no, use the sun position to calculate and find that the flight path has deviated! When I arrived in the predetermined airspace, I didn't see the bomber, and I didn't use the radio for a full minute. Call, if you don’t follow the corrected route immediately after the radio call, you, and all the pilots of your division should reflect on it. There is also the 1th division, do you know the consequences of losing a plane? What the hell? Special bomber! Don’t you guys know how secretive this special bomber was when it was refitted and trained last year?”

"Comrade Commander, Deputy Commander Chang sent a telegram from Wuhu. Minister Tang Hua happened to be at the Wuhu base, and he also sent a telegram to the Air Force Division via military lines." The indiscriminate bombing of the two division commanders received the telegram.

First look at Chang Qiankun's telegram, which is the routine training base situation report.Liu Yelou picked up Tang Hua's telegram.

"Commander Liu: The Tu-2 bomber was shot down. According to the worst plan—assuming the bomber crashed on the land of Yamato Island, we may have to make corresponding preparations. The remote control signal frequency band of the guided bomb needs to be updated and changed, okay. Now that the frequency converter is out, it can be modified as soon as possible. But in general, radio-guided bombs are not very advanced weapons. In 1952 we will have at least two new air-to-ground/air-to-ship ammunition that can be put into use. More accurate, The carrier aircraft is safer and more destructive, so there is no need to worry too much about the leak of guided bombs. But there is another thing that needs to be paid attention to by the Air Force Air Defense Force. If the US military obtains the wreckage of the Tu-2 special bomber, it may imitate the guided bomb controller on it. Equip their bombers to carry out precision bombing on me, please pay close attention to whether the US bombers use new types of bombs. Don.”

Well, "Radio-guided bombs are not very advanced weapons anymore", and then "The US military may imitate them to carry out precision bombing against me", now Liu Yelou feels that he is a bit split.

……

Yamato Island two days ago.

The two bombings by the Chinese Air Force have already made the 7th Battalion of the South Korean Marine Corps on the island panic. In the bombing on the night of June 6, a 25kg bomb directly smashed into a South Korean military camp, and there were more than 500 people who were still sleeping inside. South Korean soldiers were killed, and the sandbag walls of the trenches were blown to pieces.In view of the fact that the Chinese army and the North Korean army have begun to seize the northernmost UN-controlled islands one by one from small to large, Yamato Island is too far ahead and difficult to hold. On June 40, both the UN Command and the South Korean Ministry of National Defense agreed to withdraw troops from Yamato Island.

On June 6, the Chinese army's bombing once again dealt a heavy blow to the South Korean marines.Although the South Korean soldiers watching on the ground saw U.S. planes chasing the Chinese planes in the sky, the bombs still fell one after another, and some of them directly hit the coastal artillery for no reason, and the parts of the artillery were mixed with broken bricks. Stones are flying all over the sky.The Chinese plane flew away, and the South Korean soldiers slowly got up from the ground to clean up the mess. At this time, the American soldiers drove towards the beach in the jeep of the Military Intelligence Department.

As an intelligence station of the US military, the intelligence personnel working here are certainly not idle people.When the Tu-2 flew over Yamato Island and dropped bombs, the radar found that several Tu-2s were in abnormal entry postures, obviously not in a bombing formation.

When the bombs were dropped, the intelligence station became clearer, because they saw that in a short period of time, three of the six coastal forts were completely destroyed by bombs, and another bomb fell tens of meters away from one of the forts. bomb. Three minutes later, another huge explosion occurred in the coastal fort, and two more forts were thrown into the sky.

"Among the Chinese bombers that bombed Yamato Island, there are modifications that use guided bombs!"

A classified telegram was immediately sent to the Far East Intelligence Command in Tokyo.

Ten minutes later, the Yamato Island Intelligence Station sent another secret message:

"A Chinese bomber that dropped a guided bomb was shot down and landed in Area F, west of Yamato Island. Personnel from the intelligence station have been dispatched to study the wreckage."

After receiving this telegram, the Far East Intelligence Command blew up.

"The original telegram from the Yamato Island Intelligence Station is copied and sent to Washington," Charles Willoughby circled around the four corners of the office at the Far East Intelligence Command, "and then to the Yamato Island Intelligence Station. Order them, Retrieve all the wreckage of Figure-2, bring back every piece of debris and every dropped screw part, if necessary, mobilize the South Korean army to participate in the collection of parts, but do not disclose any information to them. Use the navy telegraph code to notify that you are heading to Yamato Island Let them draw out a landing craft to transport the wreckage of Tu-2. As for the Koreans, if the landing craft are not enough, they will wait for the next batch of fleets to withdraw.”

The Tu-2 that crashed on the beach was still burning, emitting thick black smoke.The U.S. military at the intelligence station risked the ammunition explosion and worked at close range with a fire extinguisher to quickly extinguish the fire on Tu-2.Soon the fire on Tu-2 was extinguished with the joint efforts of water taps and fire extinguishers. The U.S. Army and the South Korean Army worked together to box and pack the parts of the aircraft, and numbered each wooden box.Then the body was disassembled into eight pieces, and finally the ground was swept again, really picking up all the fallen parts on the beach.

When more than 100 people gathered around the Tu-2 to disassemble and pack the aircraft, the US military intelligence station on Yamato Island was also busy with demolition and relocation.It has been determined that the stalls will be taken away. The high-power radio stations, radio monitoring equipment, and the radar of the intelligence station must all be dismantled, and those that cannot be dismantled must be completely destroyed.In addition, various instruments and equipment, code books, confidential manuals, and work diaries piled up in the intelligence station were all packed and taken away by the US military.

At 3:5 p.m., a fleet of five landing craft arrived at Yamato Island, and the U.S. intelligence station occupied three boats: one for personnel, one for equipment, and one for the crashed Tu-2.As for the marine battalion and coastal artillery company in South Korea, more than 400 people had to stay on Yamato Island, waiting for the landing ship sent by the US military to pick them up the next day.

According to the speculation of the US military, the Chinese army is about to launch an attack tonight...

……

When the U.S. Army and the South Korean Army were busy on Yamato Island, Deng Hua, deputy commander and deputy chief of staff of the Volunteer Army at the Jilin 50 Center, looked through the intercepted U.S. telegrams.

After reading several relevant reports, Deng Hua wrote a report telegram to the Beijing War Situation Center.

"This morning, when the Tu-10 bomber formation of the 2th Air Division bombed Yamato Island, it was intercepted by the US F-86. Three Tu-3 and one Tu-2 special bomber were shot down. According to the deciphered enemy station telegram, this The Tu-1 crashed on the land of Yamato Island, and the U.S. military immediately used a lot of manpower to pick up the Tu-2 parts, and transported all the Tu-2 parts away this afternoon."

The staff officer read the telegram to Su Yu. Su Yu was silent for a long time, and then sighed: "The Tu-2 special bomber is a good thing."

Staff officer: "Air Force Commander Liu Yelou was very angry when he heard the news, and he is already preparing a plane to fly to Anton."

Su Yu: "I don't know if the Americans will find a way to counter it after stealing it. If the guided bombs are countered by the Americans, it will be difficult to liberate Taiwan in the future."

Suzhou, Magnetic Machine Factory, Ministry of Electronics and Information Industry.

Tang Hua visited here last year and saw a whole workshop of former embroidery workers busy assembling magnetic core memory.

When I came here this year, the workshop is still there, and the factory area of ​​the magnetic core memory has been expanded by one-half, and there are still female workers assembling the magnetic core memory.

If there is any difference, last year the magnetic core memory was assembled with a 2.5 mm magnetic ring, this year it has been replaced with a 1.8 mm magnetic ring...
