Chapter 230 Liyan-1 Military Reconnaissance Satellite
Originally, there were troops from the three armies of the Southern Alliance in Hangzhou.
A force consisting of one main army and two temporary armies.
The three armies built multiple coastal defense positions in Hangzhou Bay to protect the bay.
However, with the successive fall of Xunyang and Hongcheng, the Fuxing Army had already posed a real threat to southern Hunan and Dongjiang provinces.
Tanzhou sent a large number of troops to Pingxiang, on the border between southern Hunan and Jiangnan Province, to block the Fuxing Army.
However, Dongjiang Province does not have many troops to deploy.
After all, Shanghu still needs heavy defense, so it is impossible to withdraw troops from Shanghu.
There is no need to think about the hundreds of thousands of defenders in southern Hunan. The railway lines have been cut off and they cannot be transferred.
Although the Southern Alliance had more than two million troops before the war, more than 100,000 of them were killed in the Battle of Xunyang.
A large number of troops are needed to block the opening of the Changhe River, and the war in Zhulu is also tense.
Therefore, this also led to the fact that the Southern Alliance had few troops available.
Subsequently, the Shanghu landing battle broke out, which also meant that the landing focus of the Fuxing Army would be on Shanghu, rather than Hangzhou.
So Wu Zhichang thought of transferring the troops in Hangzhou to the Guangxin front in Dongjiang to block the offensive of the Fuxing Army.
Then troops will be dispatched from other places to fill the gap in Hangzhou.
It was also because of this that the Southern Alliance dispatched two armies and two divisions from the Hangzhou defenders and rushed to the Guangxin front in the south of the Yangtze River.
Now there is only one division of troops left in the entire Hangzhou City, and this division is a temporary division reorganized from the Dongjiang Province Security Force.
This was actually because Wu Zhichang had a glimmer of hope in his heart.
It is believed that the focus of the Fuxing Army is on Shanghai and it will not pay attention to Hangzhou.
He also secretly transferred troops from Hangzhou, and the troops set off for Guangxin by train at night.
There are only more than 300 kilometers of railway distance between Hangzhou and Guangxin, so it takes about seven hours to get there.
Wu Zhichang thought he was doing it very secretly, but he didn't know that the Fuxing Army had a variety of reconnaissance methods.
At this moment, there are already several eyes of the Renaissance Army in space.
After several months of construction at the Yuntian Base, the second phase of the base has been completed, and the final third phase is now underway.
During this period, the Yuntian Base was also busy. As long as they found a launch window, they would launch it, even if it was only an hour or even ten minutes.
In Jiang Hua's words: Even if the launch fails, it's no big deal as long as there are no casualties.
It is for this reason that the Yuntian Base was able to launch the missile with confidence.
The launch of Explorer 1, 2 and 3 satellites has also accumulated a lot of experience for the Yuntian Base.
Two months ago, in February, the Yuntian Base launched its first military reconnaissance satellite, Clairvoyant-1.
The satellite was sent to an orbit with a perigee of 160 kilometers and an apogee of 980 kilometers. The satellite's operation cycle is 90 minutes, and it can orbit the planet in one and a half hours.
The satellite weighs about 2 tons and is equipped with a catapult-capable return capsule.
The satellite's return capsule carries four cameras: two panoramic cameras, a wide-area low-resolution imaging camera, and a small index camera.
The wide-area and index cameras are both used to search for large-scale, generalized targets. Once the approximate target is found, a panoramic camera with a resolution of about 7 meters is used to take pictures.
After the shooting is completed, the life of the satellite will come to an end.
Because data transmission from space to the ground is not possible in this era.
The satellite's return capsule is equipped with a camera system, film, flight power, navigation beacons, parachute and anti-shock system.
When the satellite reaches the designated orbit and the ground control station sends an ejection command, the satellite will eject the return capsule that accounts for most of its weight.
The satellite will then be landed and recovered at a designated location in the three northern provinces.
Finally, the film is taken out for development, and a large number of photos containing useful information are obtained.
This is the working procedure of the Clairvoyant-1 reconnaissance satellite.
After the return capsule was ejected, the satellite lost its function and was left to drift in space without power, becoming space junk.
What's more, the maximum lifespan of a reconnaissance satellite is less than 30 days.
Because with current technology, the satellite's power source is mainly internal batteries, and there is no photovoltaic technology to extend the satellite's life.
Basically all satellites have a lifespan of less than 30 days.
Launch it when needed.
So in March, the Yuntian Base launched four Qianliyan-4 reconnaissance satellites in succession.
The orbit of one of the satellites passes over Hangzhou, and it happens to be during this time period.
So when the satellite finished taking a full circle of photos, the ground control station ejected the satellite that had completed the shooting mission back and successfully completed the recovery mission in a certain area in Heilongjiang Province.
After the staff developed a large number of photos, they discovered something unusual in Hangzhou.
The General Military Intelligence Bureau then dispatched its intelligence network in Hangzhou to conduct a more detailed investigation, and ultimately discovered that Hangzhou was short of troops, with only one division remaining.
The General Staff then took decisive action and airdropped the 21st Airborne Division from Zhili Province to Hangzhou.
At the same time, the Air Force located in Jiangnan Province provided ground support.
However, on the day of the mission, the weather conditions in Hangzhou were very bad and there was a heavy rain.
So the action was postponed for one day.
Since the defenders of Hangzhou are all concentrated in Hangzhou Bay, the urban area of Hangzhou is short of troops, with only one battalion of Southern Alliance defenders.
Therefore, the 21st Airborne Division carried out a low-altitude airborne landing directly in the open space on the bank of the Qiantang River east of the urban area of Hangzhou.
On this day, white umbrella flowers were floating in the sky above Hangzhou.
At this time, the defenders in Hangzhou Bay were shocked.
However, by the time the 21st Airborne Division landed, it was already too late to react.
When they sent troops to Hangzhou, they encountered the 21st Airborne Division Infantry Regiment heading to Hangzhou Bay, and the two sides fought a battle.
The battle was not fierce, it was completely one-sided.
Because the airborne troops of the Renaissance Army are no longer a light infantry, but an airborne heavy armored force.
Hundreds of airborne infantry fighting vehicles are equipped, which is also a derivative model of the multi-purpose infantry fighting vehicle.
The C-130 tactical transport aircraft can carry one, and the C-124 strategic transport aircraft can carry two.
For this airborne operation, the Air Force dispatched a total of 272 transport aircraft of various types, flying two sorties a day.
Hangzhou has fallen!
When the bad news reached Nanjing, President Wu Zhichang was furious.
"Hangzhou must not be lost. Immediately dispatch reinforcements to attack Hangzhou and recapture it."
But after shouting for a long time, he realized that he really had no troops to withdraw.
Zhuolu, Shanghu and Hongcheng were all under attack, and the Fuxing Army directly opened four or five fronts.
Each front tied up a large number of SAARC troops.
There is still a group of troops in Yangcheng, but they cannot be withdrawn.
Because Yangcheng only has one railway leading to Tanzhou and Jiangcheng, and there is no railway leading to Jiangnan Province or Minyue Province.
It was at this time that Wu Zhichang realized that his defense line seemed to have collapsed during the battle.
"Order the 9th Corps in the Guangxin direction to withdraw immediately and recapture Hangzhou."
Now we can only give up the idea of encircling the Fuxing Army in the direction of Hongcheng.
If the Fuxing Army's paratroopers gain a foothold in Hangzhou, the 9th Corps will be attacked from both sides.
At this time, there is no point in continuing to defend the Guangxin area.
So the 9th Corps, which had just arrived in Guangxin, began to march back.
It is easy to get to Guangxin, but it is not so easy to go back.
After the airborne operation in Hangzhou was launched, the two motorized infantry divisions of the 7th Army in the Guangxin direction launched a fierce offensive towards Guangxin.
At the same time, the 21nd Airborne Infantry Regiment of the 62st Airborne Division in Hangzhou sent troops to set up a blocking line in the direction of Wuxiao County.
The Air Force also sent bombing units to launch large-scale bombing attacks on the 9th Corps and destroy railway lines.
As I said, it’s easy to come here, but it’s hard to go back.
After the fall of Hangzhou, Chen Rui's Fifth Corps was the most passive.
After receiving the telegram that Hangzhou had fallen, Chen Rui was immediately caught off guard.
Hangzhou City is located behind the Shanghu Defense Line. It would be extremely devastating if it were lost just when the Fuxing Army was attacking the Wusong Fortress.
Fortunately, the 9th Corps has been transferred back to Nanjing, but it is still unknown whether it can recapture Hangzhou.
So he had to send an army to set up a defense line on the railway line and highway from Hangzhou to Shanghai.
This resulted in Chen Rui having no troops to mobilize.
One army guards the Wusong Fortress, and the other army guards the Nicheng Fortress.
So Chen Rui had to ask for reinforcements.
Now Wu Zhichang has no troops to reinforce Chen Rui.
What's more, it's not just Chen Rui who needs reinforcements.
So Wu Zhichang approached advisor Ross Lewis and asked him for international reinforcements.
“We can’t withdraw too many troops, and even if we transfer troops now, we can’t enter Dongjiang.
You are strategically surrounded."
Army Lieutenant General Ross Lewis actually no longer had any hope for this battle.
The Southern Alliance was completely defeated, playing passive defense everywhere and losing ground everywhere.
The Fuxing Army first broke through Hongcheng, forming a central attack and separating the Southern Allied Forces in the central and eastern parts.
Shanghu relied on the fortress to delay the offensive of the Fuxing Army for a while, but with the fall of Hangzhou, the fall of Shanghu became a foregone conclusion.
When Hangzhou and Shanghu fell into the hands of the Fuxing Army, the entire Southern Alliance was strategically encircled. The center was blossoming, strategically divided, and completely encircled. The reinforcements from outside could not enter, and the troops inside could not leave.
Basically, the Southern Alliance's front lines collapsed except for Tanzhou and Zhuolu.
Moreover, when we go to Shanghai, it will cause a chain reaction, and Zhuolu will not be able to hold on.
So in the view of Lieutenant General Lewis, the Southern Alliance has entered the countdown to its demise.
He also reported the situation to the country.
So now the Southern Alliance can basically consider a retreat.
