Back to the Republic of China to be a editor

As soon as it got dark, Yunshan City was attacked from all sides.

The first battalion of the 8th American Cavalry Regiment was stationed at the stronghold in the north of the city. Although there were 155mm howitzers to assist in blocking the shooting, it was still attacked by the two battalions of the 347th Regiment. The battle continued until 2 am on the 2nd, and the US troops in the stronghold retreated across the board.

The second battalion was stationed at the stronghold in the west of the city, and one battalion of the 348th regiment broke into the position directly in the dark. The U.S. military first ate hundreds of grenades, followed by semi-automatic rifles and assault close-range fire.After half an hour of chaotic fighting between the two sides, the other two battalions of the 348th regiment finished clearing the Korean army post and joined the attack on the stronghold.At 3 o'clock in the morning, the second battalion of the US military in the stronghold west of the city retreated southward.

To the south of Yunshan City is the headquarters of the 8th American Cavalry Regiment, the 117rd Infantry Battalion, the Howitzer Battalion and two-thirds of the Tank Battalion.After the battle broke out in the north of the city, Palmer ordered a tank company to cooperate with the third battalion to pass through Yunshan City to support the first battalion in the north of the city, and bumped into the 349th Regiment of the 349th Division who sneaked into Yunshan City. The 1th regiment was searching for the division headquarters of the 4st South Korean Division in Unsan City as a unit. One of the companies found 39 American tanks running along the street in front of them and immediately called nearby troops.In fact, both sides are not very familiar with the roads in Yunshan City, but the 117th Army has fought a lot of street battles from Siping to Liaoshen to Tianjin.The battle quickly entered the familiar territory of the 349th Division. At two o'clock in the morning, that is, when the U.S. troops in the northern stronghold were retreating, the two battalions of the 350th Regiment and the 11th Regiment who rushed to the battlefield had entered the mode of house-by-house clearance, and the U.S. reinforcements in the north of the city dropped 8 vehicles The destroyed tank was about to flee back to the headquarters of the [-]th US Cavalry Regiment in the south of the city.

Dayu Cave.

The communications soldier trotted all the way, pulling the phone line to Zhisi's cave, and Ye Ting picked up the phone receiver. "Hello, the 39th Army? I'm Ye Ting."

"Report to Commander Ye, from 8 o'clock last night to now," Wu Xinquan looked at his watch, it was 3:20 in the morning. "Our troops have defeated the U.S. troops in the north and west of Yunshan City. The 117th Regiment of the 349th Division entered Yunshan City and encountered the U.S. and Korean troops. After fierce fighting, the enemy retreated to the south of the city. Now our army has controlled most of Yunshan City. Destroyed 1 US battalion in the west of the city, defeated the 12th regiment of the Korean Army in the northeast of the city, and completed the siege of the US military stronghold in the south of the city!"

"Now, the 40th and 119th Regiments of the 356th Division of the 357th Army are also moving to the south of Yunshan Mountain, and you have full command of the battle." Ye Ting looked at the map of the headquarters. The 357rd regiment formed a support team to block the 343th American Cavalry regiment going north for reinforcements; the second and 5th regiments set up a battalion each in Longchengli, Sanshuili, and Longxing. This is the route for the US troops to flee south in Yunshan City; Third, intensify the encirclement and annihilation of the US military base south of Yunshan City, and their command organization must not be allowed to escape."

In the Yunshan battle in history, although our army fought very smoothly, the summary of our army's results after the war was finally determined as "severe damage to the 8th Cavalry Regiment of the 8st US Cavalry Division" rather than "total annihilation".The first reason is that the U.S. troops scattered to break through the siege, and even crossed the mountains and mountains on a small scale, and almost a battalion of troops ran away; the second is that although the headquarters of the regiment was taken down, more than a dozen commanders including the regiment leader ran away.After discovering that the battle situation in Yunshan was irreversible, the commander of the 9th Cavalry Regiment 200 (regiment-level commander), some staff officers, and more than 5 soldiers took trucks and tanks and rushed to Bochuan along the road, while the [-]th Cavalry Regiment in the south The tanks were heading north again, severely compressing our army's blocking line, and the blocking troops could only watch helplessly as the line of Sherman tanks rushed back.

How close is the 8th Cavalry Regiment to being wiped out?Actually not much worse.Maybe add another division to attack/resist, or add two artillery regiments, or?In short, as long as we know in advance that there are more U.S. troops in Yunshan City, the combat deployment of our army may be very different.

Leading hole, blocking line.

Since November 11, Yunshan has been attacked from all sides. The 1th US Cavalry Regiment on the south side of Yunshan has moved northward under Gay's order to open the road leading to Yunshan and rescue the 5th Meiqi Regiment.

At 6 o'clock in the morning, the 5th American Riding Regiment departed from Longshan Cave and headed north, and stopped at Longtou Cave.The sky was bright, and a group of soldiers came on foot from the north in the morning mist. After seeing the US military convoy, the leading soldier negotiated loudly with the US military in Korean.

"They are the troops of the 12th Regiment of Unsan South Korea. They have suffered heavy losses from the attack of the Chinese army and are retreating." Soldiers in the US military who understand Korean translated what these soldiers said.

The convoy of the 5nd Battalion of the 2th U.S. Cavalry Regiment paused on the road. Watching this group of Korean soldiers pass by, the battalion commander was trying to identify which officer had the highest rank among them, so that he could ask him for some front-line information.

"Wow! Wow!" - The battalion commander couldn't understand what the soldiers were saying, but the group seemed to be very excited.Then, a black dot was thrown from the soldier's hand and got into his jeep!

In the last two days of combat, the 343 regiment captured a large number of South Korean soldiers and captured many uniforms.Looking at these clothes and hats, the commander of the 2nd Battalion and 3rd Company had a strong desire to pretend to be the South Korean army to cheat the US troops.In the early morning, the 343rd regiment discovered that the U.S. army was in front of Longtoudong, and the entire team was stopped in units of battalions. They probably wanted to send reconnaissance troops to investigate whether the place was safe before passing through. A reinforced company of the 2nd Battalion all wore South Korean military uniforms and pretended to be in formation. With a relaxed look, he walked towards the American army parked on the road.

……

Ten minutes later, when the nearby U.S. troops approached the 10nd Battalion of the 5th U.S. Cavalry Regiment with their tanks, the reinforced company of the 2rd Regiment had already left, leaving behind dozens of U.S. corpses, more than 343 wailing wounded soldiers, and a highway. Car wreck.Before withdrawing, the reinforced company also blew up all the mortars of the 100nd Battalion of the 5th US Cavalry Regiment.

In northern North Korea on November 11, "fierce battles broke out on every inch of turf."In Yunshan, the 2th regiment of the 8st U.S. Cavalry Division had only the regiment headquarters and half a battalion of infantry left, and they used strongholds and tanks as firepower to support them and stand by for help; tens of kilometers east of Yunshan, a regiment of the 120th Division and the 119th Division directed The South Korean Army in Ningchuan launched an attack; in Taichuan and Guicheng, the 66th Army set up multiple blocking lines to prevent and contain the 24th Infantry Division of the US Army that was about to enter here; the 50th Division of the 148th Army fought in Guchang a few days ago In the middle, I made soy sauce, and now the 149th and 150th divisions are marching into Sinuiju, and then they are preparing to attack the Daguandong area.

On the Qingchuan River, the 38th Army, the number one main force in Shino, is attacking the blocking positions set up by the 7th and 8th Divisions of South Korea.

The continuous assaults of the Volunteers made the US military see the combat effectiveness of the Chinese army for the first time.

On the same day, Beijing, Ming Tombs.

Tang Hua actually didn't want to set off firecrackers on the graves of the emperors.But looking at Beijing, with fewer residents, far away from the urban area and the airport, and relatively convenient transportation, the only place where a tactical missile test site can be established is the Ming Tombs.

In fact, the missile test was not in the mausoleum area, but a little bit next to the Ming Tombs.

A team of cars came to the newly completed missile test site.

"Everyone, this is the anti-aircraft missile we are going to test today. What you have developed in the past two months is now a key component in the missile system."

Tang Hua specially used a large truck to pull out the team responsible for the development of the missile computer from the Beijing Computer Institute and the Communication Electronics Institute.During this period of time, they were really exhausted. Apart from arranging logistics for them to eat and drink well, the best incentive was actually to let them see how amazing the things they made with their own hands.

"Film team, are you in place?" Tang Hua took the walkie-talkie and personally coordinated the preparations of the various teams on the scene.

"The three movie cameras are already in place, and the filming crew is in place!"

These are three movie cameras and three photographers borrowed from Beijing Film Studio. They are responsible for taking pictures of the whole process after the launch order is issued. If there is something wrong with the first test launch of the missile, you can still watch the video to find the problem. where.

"Is the target group in place?"

"Equipment and personnel are ready!"

"Release the target."

On a mountain three to four kilometers away, two staff members who had just climbed up the mountain released the rope, and a huge hydrogen balloon slowly rose.The hydrogen balloon is more than 2 meters in diameter, and its exterior is covered with tin sheet or tin film, which shines brightly in the winter sun.When it was about 2 meters above the ground, the length of the rope reached its limit. The staff fixed the balloon, then walked a little downhill for more than ten meters, and hid in the two cat ear holes dug before.

"This is the launch vehicle for anti-aircraft missiles." Tang Hua led the research team from the Institute of Computer Science to visit the weapons to be tested today. "The missile is produced in Dalian, with a maximum range of 8.5 kilometers and a maximum height of 4500 meters. The launch vehicle is a truck imported from the Soviet Union, and the Beijing Auto Repair Factory remodeled the missile launcher and the pitching mechanism."

"In addition to the launch vehicle, the air defense missile system also has a radar, a fire control command vehicle...the fire control computer of the command vehicle was also assembled by you, and you also participated in the transformation work, right?"

The members of the research team nodded, but they still couldn't take their eyes off the missile launch vehicle.Now, what is mounted on the launch vehicle is not a wooden model, but the first batch of self-missile samples of the Hongqi-1 air defense missile.

Tang Hua has read the data in the manual, and the Hongqi-1 missile weighs 180 kilograms.

The Soviets may think this weight is unbelievably light, but Tang Hua knows that the French "Sidewinder" bomb weighs only 85 kilograms, and this is because two guidance systems are installed on the missile of the Sidewinder system at the same time...

Chapter 74, 40 rockets are out of stock

1950 11 Month 2 Day.

At this moment, the Lavochkin Surface-to-Air Missile Design Bureau of the Soviet Union is tinkering with their long-range anti-aircraft missile "Project 205". Unfortunately, throughout 1950, the sample bombs of Project 205 were in a state of Brownian motion, and the missiles launched were crooked. , Let him point to the east and he fights the west.It would be four years later that Lavochkin's 205 project was completed and became S25, which NATO named SA-1 "Gilder".Even if it is in service, SA-1, with its length exceeding Dongfeng-21, has become a special anti-aircraft missile for Soviet homeland air defense that is so clumsy that it can only hit high-altitude bombers.

At this moment, several arms groups in the United States are developing surface-to-air missiles, all of which are blooming in strange shapes.The US Air Force commissioned Boeing to develop the MX-1599 surface-to-air missile. It looks about the same size as an F86 fighter jet. In fact, it is an unmanned fighter jet with a range of 700 kilometers. The way to shoot down enemy planes is according to the preset method. The ballistic flies into the enemy bomber group, and then detonates the nuclear warhead.

The U.S. Army is developing the Nike-1 surface-to-air missile, which is a bit like the SA-1. It is a normal air defense missile guided by radio commands. Unfortunately, like the SA-1, it is still in the Brownian motion state.

This is the age of the strategic bomber.

Six years ago, the Soviet Union witnessed how American bombers crushed Germany and Japan to death one city at a time.The U.S. Air Force has done its own deduction, and the conclusion is that if a country also throws atomic bombs at the face of American bombers, the U.S. Air Force will not be able to prevent it.The first-generation air defense missiles of the United States and the Soviet Union were all scared out of strategic bombers.

Compared with the foolishness of the two gangsters, the Hongqi-1 missile launch vehicle in front of the project team is simply a product of another era.Only 2.5 meters in length, with a slender body, four large directional stabilizer fins at the tail, a pointed warhead, and four small triangular rudders near the head.The nozzles of the tail rocket motors are painted black. In fact, this is the booster that the first generation of Soviet anti-ship missiles was intended to use.The inclined launcher is installed on a prototype turntable, and four Hongqi-1 surface-to-air missiles have been placed on the shelf, pointing obliquely at the sky.

"The guided fire control computer of Hongqi-1 was developed by you, so you should be very clear about how this missile works." Tang Hua said, "At the end of October, we conducted a test launch of the self-controlled missile, which was very successful. Based on this Today, we have accelerated the progress of the test, and we will start the low-altitude balloon shooting test today. The low-altitude balloon shooting means that the computer you designed has really started to be used in this system, so you have to see it clearly!"

Tang Hua's call on the walkie-talkie officially started, and the loudspeaker on the test site began to sound like an air raid siren.Hearing the sound of the siren, everyone returned to their shelters. Tang Hua also led the project team with a dozen people to drill into a semi-underground fortification.There was a sound of "launch" from the intercom, and a burst of flames suddenly appeared on the launch vehicle parked in the center of the test site. The first Hongqi-1 flew away from the launch pad with a long orange tail.The high-temperature tail flame of the missile was roasted, and the launch vehicle was suddenly covered with faint smoke.Hongqi-1 is like an arrow leaving the string, flying towards the balloon on the top of the mountain.Less than 10 seconds later, Tang Hua saw through the telescope that a cloud of smoke suddenly exploded from the upper left of the balloon, and then the balloon with a diameter of more than two meters turned into countless small rags.

"How many meters is this hit error?" Tang Hua was two or three kilometers away, and the telescope could not measure the deviation between the two, so he was a little uncertain.A balloon is another thing that just hits a piece of shrapnel and explodes with a bang.For the time being, it is considered a hit, and the error value will go back to watch the film reels of Beijing Film Studio.

The balloon was blown up, and the 300-meter-long string tied to the balloon also fell from the sky, spreading all over the balloon release site on the top of the mountain.The two staff heard from the intercom that it was safe, walked out of the cat's ear hole, made another balloon and hung it out.

"Second shot!"

Almost exactly the same as the first shot, the missile flew for nearly 10 seconds and hit the upper left of the balloon. The fragments from the explosion were enough to cover the balloon, and it exploded in the air again.

The third and fourth shots will not hit the balloon on the top of the mountain.Under the command of the walkie-talkie, a balloon release team at the foot of the mountain released a balloon of about the same size, only rising to a height of a little over 100 meters.

At this height, when the fire control radar illuminates the balloon, the electromagnetic waves also illuminate the mountain behind.The balloon has radar echoes, and the mountains behind may also have radar echoes.Whether the modified COH-100 radar removed from the height of 4 can accurately identify the target depends on the filter circuit modified by Tang Hua.

With a parabolic trajectory, the third missile first flew to a height of 400 meters from the ground, then pressed down on the warhead, and flew obliquely downward from the height to the balloon.

"Boom!" The missile exploded almost directly against the balloon, and the balloon that was reflecting sunlight just now disappeared instantly.

The fourth shot was exactly the same as the third shot, except that the explosion point of the missile was not as close to the balloon as the third shot. Of course, it was still within the effective killing range, and the balloon was also torn apart by the fragments.

This result is not bad, Tang Hua nodded.Behind him, a dozen researchers from the project team had already blown up.
