Chapter 715: Spring returns to the North with plum blossoms
The handle of the bucket points to the east, and spring has returned to the land outside the customs again.
The white ice in Vladivostok Harbor was swallowed up by the green waves, and the rivers were filled with warm spring water. As soon as the azaleas on the green meadows bloomed, geese and red-crowned cranes came in droves over the top of Mokuowei, diagonally
Passing over the Xihot Mountains, they flew towards Heilongjiang where they gave birth to their children.
The spring breeze that turned into rain brought migratory birds returning to the north, and also brought the rivers under Beihai Town to the peak of their flow. Huge and crystal clear ice sheets floated and collided with the surging river water.
There were bursts of roaring. Although this scene was extremely magnificent to the literati, for those villages along the river, it heralded the coming of disaster.
It is said that the upper reaches of Heilongjiang River flow from west to east. After passing Heilongjiang City, it turns to flow southeast, and then turns sharply southward after passing Kubutlin, making this section of the river form a large arch. Songhua River and the middle reaches of Heilongjiang River
At low latitudes, the temperature rises quickly, but in the upper reaches of Heilongjiang at high latitudes, the river opens later, resulting in the formation of an "inverted river".
Once the blue and hard ice gets stuck, it will form an ice dam, and then squeeze each other and rush up to the river bank. The two or three-meter-high ice will rush against the ground, destroying everything along the way, including trees.
, rocks, roads, villages, and cultivated land. The most serious consequence of this is that the cultivated land is destroyed, making it impossible to grow food crops that year. Even the humus soil on the surface will be destroyed, and it will take several years to restore the soil fertility.
Since the construction of the "Bohei Railway" started five years ago, at this time, the Northern Navy stationed in Khabarovsk and Heilongjiang City will be ordered to dispatch to blast the ice on key river sections. They will also be dispatched after the ice period begins.
Artillery bombards important river sections that are prone to ice dams.
Located in an open space two kilometers northwest of the Humar Military Station, six 75mm field guns were lined up. Because shelling the ice was not a battle, no bunkers were dug.
However, what is different from previous years is that in another open space 800 meters away on the west side, there is a 105mm howitzer that is different from all the artillery of the North Korean Navy. The perimeter of the gun position here is surrounded by sandbags.
The one-and-a-half-meter-high breastwork, in addition to six artillerymen, there are also several technicians from the military-industrial complex.
At a hill observation point 600 meters away from the north of the position, Zhao Liang, wearing a thick military coat, bent down in front of the artillery rangefinder and squinted for a while, then casually asked: "Are you all ready?"
"Reporting to the commander, all bombardment parameters have been calculated."
"Where's the ammunition?"
"Twenty rounds have been sent up."
"It's getting late, get ready for the test firing." After Zhao Liang finished speaking, he turned to a technician next to him and sighed: "I have been busy for more than two years. Whether it is a mule or a horse depends on today."
The technician pursed his lips and said, "It's not a big problem. More than 300 rounds have been fired on the test field."
"One minute to prepare!" the artillery battalion commander gave the order over the intercom at the artillery observation station, and then entered the countdown. "...5, 4, 3, 2, 1, fire!"
With an earth-shattering loud noise, the muzzle of the 105mm howitzer spurted out fire, and the shock wave stirred up a large cloud of smoke and dust behind the artillery, instantly shaking the snow on the ground, revealing the dark land. Immediately,
Accompanied by a dull explosion, fire and gunpowder smoke rose from the thick ice on the river surface, splashing water columns tens of meters high.
"The artillery fire is normal!"
"The ballistics are normal!"
"Hit the target!" In the temporary artillery observation station, the command was heard one after another. Several technicians were recording various data in their notebooks.
Soon, the loader on the 105 howitzer position had finished loading the second shell. The gunner quickly adjusted the firing angle of the artillery according to the squad leader's order to shoot Zhuyuan. Then there was another loud bang,
Where the shell hit, a huge block of ice that was three meters thick and covered an area of over 5 square meters was shattered into pieces.
"Oh my God! This is too powerful. Comparing our guns with it would be a joke!" On the 75mm gun position, several artillerymen stuck out their tongues with envy on their faces.
"Look at their caliber, they are almost as thick as our thighs!"
"I just don't know when this big guy will be able to equip us. Oops!" As soon as the gunner finished speaking, he received a heavy kick on the butt. Looking back, he turned out to be the squad leader.
"You brat! Are you getting tired of the old? No cannon is as good as our 75 cannon, which shoots fast and accurately. I used this cannon back then, and it made Rakshasa ghosts cry for father and mother..."
The artillery squad leader was about to say more when he heard an order coming from the walkie-talkie: "Test fire each gun of the 75mm gun! One minute to prepare!"
After that, the six 75mm guns were tested one after another. Although the shots were all quite accurate, the shelling effect seen with the naked eye was not even a little bit worse than that of the 105mm. Basically, if the 105mm fired one shot, the 75mm gun had to be fired.
Only two shots have the same effect.
The artillery squad leader who had kicked someone before spat on the ground, thinking that I should change this artillery piece.
After the "Battle of Usoliya", the North Navy's artillery configuration issue became more and more prominent. The main reason is that the range of the 82mm mortar and the 75mm gun are not much different, and the killing power of the former is obviously higher than that of the latter.
Those who are taller.
The maximum range of the 82mm mortar using No. 6 charge is 4660 meters, the maximum range of using the long-range charge is 5700 meters, and the maximum range of the 75mm gun is only 6000 meters. In addition, the maneuverability of the field gun
Not as good as mortars, which makes the 75mm gun seem a bit useless.
After all, the original purpose of replicating this gun was to get rid of the dependence on the 122 howitzer, and at the same time to give the military-industrial complex a try, so we chose a model with a barrel that was not too difficult to process and a shell that was relatively easy to produce.
Of course, the Navy is quite satisfied with the 75mm gun. It has a fast rate of fire and low recoil. Only I can bully others, and no one else can bully me.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! In addition, because the 122 grenade Beihai Town cannot currently produce, Zhao Xin has to spend huge sums of money to purchase it every time, so the Beihai Navy urgently needs to develop a
A heavy artillery piece for this time and space.
After comparing the data of various caliber howitzers during World War I and World War II in another time and space, Zhao Liang finally proposed to imitate the LeFH18/40 105mm howitzer and make it the main equipment of the North Korean Navy's artillery in the next twenty years. In addition, 75mm
The artillery will gradually withdraw from the frontline to support firepower, and the artillery batteries attached to each regiment will also all be replaced with 82 guns.
Speaking of the 105mm howitzer produced by the Germans in another time and space, the early model was very heavy and required at least six pack horses including the ammunition cart. The later derivative leFH18/40 was different, in addition to a more efficient muzzle system
The retractor reduces the recoil, and the gun barrel is also installed on the gun mount of the 75mm Pak40 anti-tank gun. The new gun mount lightens the overall gun body, and the rate of fire is also increased.
In addition, the production volume of 105mm howitzers was very large. In another time and space, both private individuals and museums had collections. It was easy to buy two or three and take them back as samples. Zhao Xin even spent a lot of money to get a German
A complete set of design drawings.
Of course Zhao Xin would welcome something that could save him money, and save a lot of money. You must know that every round of today's 122 artillery shells was exchanged for gold for him, which not only hurts his heart, but also hurts his body.
However, he also knows very well that leaping from 75 mm to 105 mm is not as simple as making the barrel thicker. In addition, the problem of artillery shells has always been a big mountain in front of the military-industrial complex.
The manufacture of artillery shells is different from bullets. The warheads and armoring processes of bullets are automatically completed by machines. The artillery shells start from the manufacture of steel billets and go through more than thirty stages of machining before the gunpowder and cartridges can be assembled.
In addition to lathes, cutting tools, fixtures, and measuring tools, all of them must be made by ourselves. Even the oil-based cutting fluid supply system for processing must be made by ourselves. Cutting fluid and petroleum jelly are large-scale consumables and must be manufactured by ourselves.
Zhao Xin bought the money and made a lot of money.
So starting three years ago, the military-industrial complex led by Zhao Liang began to research how to climb this mountain. In addition, Zhang Bo's petroleum system and Fang Hua's laboratory also began to produce oil-based cutting fluid and Vaseline.
In the process of buying artillery shell samples, Zhao Xin accidentally got an image of artillery shells produced in the early 20th century. This made Zhao Liang overjoyed, so he asked a large group of technical workers in the arsenal to read it every day and analyze each of them bit by bit.
Each step and the lathe tools and fixtures used determine the process steps. After everyone has seen it almost, Zhao Liang divided the workers into different processing groups to study their respective processes.
Beginning in the autumn of 1790, the military-industrial complex selected sites for artillery factories in various locations in the outer northeast, and finally selected Wanda Mountain in the northwest of Khabarovsk. This location was chosen because of its flat terrain and convenient transportation. Heilongjiang
The Kulu River, a tributary of the river, is not far away and can be transported by water in spring and autumn.
By the end of the slurrying period in the spring of 1791, the construction of the artillery shell factory, artillery factory, fuze factory and assembly factory began. At the same time, a short-distance railway and road from Khabarovsk to Khabarovsk were built.
It took more than a year to complete the construction of the four factories and install many equipments. The people from the power system also cooperated to pull out a dedicated power supply line from the supporting power plant of the steel plant and built a distribution station.
.When the factory was ready for use, Zhao Liang’s workers also made the first batch of jigs and measuring tools for processing. After that, it was trial after trial and failure again and again. The key was the processing accuracy of the workpiece, which was one millimeter off.
Will not work.
The artillery shell factory is busy conquering the mountains, and the steel factory and artillery factory also have their own important responsibilities. What about electroslag remelting, medium carbon nickel-chromium platinum alloy steel, self-tightening of the barrel, rifling, chrome plating, etc. Although the electroslag remelting furnace
, large drilling machines and boring machines used for boring have corresponding equipment. The problem is not big, but the self-tightening and rifling of the barrel is not so easy.
Zhao Liang's approach was to sell dog meat on sheep's head. In the name of a middleman in an underdeveloped country, he customized two sets of 5,000-ton steel pipe hydraulic presses from a domestic factory, which cost Zhao Xinda several million. As for the rifling machine,
You can only make it yourself and scale it up with reference to the barrel rifling machine. The equipment material and cutter head will definitely be different.
Compared with the other three factories, the assembly plant has the highest safety standards. In addition to high-standard guards, it is also far away from the three factories. Workers all wear white protective clothing, anti-static gloves and gas masks. There are also
An ion blower and ion blower are installed to eliminate static electricity; it is no joke to know that static electricity can detonate explosive particles in the air.
In this way, the thousands of skilled workers trained by Beihai Town over the years worked hard for two years. The steel metallurgy, chemical industry, petroleum and other departments worked together to finally produce two qualified 105mm howitzers in the winter of 1793.
and the first batch of 105*155 high-explosive bombs.
According to Zhao Xin's opinion, as long as there are no accidents in the test firing of two thousand rounds, the artillery will basically be considered a successful imitation, and then it can be mass-produced and replaced.
Entering May, the Beihai Navy began a new round of personnel changes, which Zhao Xin had been thinking about for a long time. Generally speaking, except for the Western Front troops, all officers who had served as regiment-level officers for more than two years had undergone changes.
Although the transfer of chief officers will take at least half a year for the officers and soldiers of the army to get used to each other, in order to avoid the emergence of mountainous doctrine within the army, Zhao Xin must do this and persist in it. According to his considerations, after this personnel adjustment
Until the troops entered the customs, they basically stopped moving.
According to the order of the Northern Navy Headquarters, Sheng Haizhou and Zhao Jiuzang finally left Pingshi City - the former "Yenisesk". The former, the nominal Chief of Staff of the Northern Navy, will be transferred to Jiaodong to replace Lu Shoushan
He was fully responsible for commanding the combat missions in Shandong; the latter was transferred to the training headquarters and served as the deputy commander in charge of recruit training. Wu Siyu still held the position.
The person responsible for replacing Jiuzang and going to Pingshi City was Yang Zhongming, the former commander of the 19th Infantry Regiment. Zhou Monk, the commander of the 12th Regiment, was transferred to Chiyan City. Together with Yang Zhongming, he assisted the Cossack Emirate and Tsarist Russia in one direction, one in the south and one in the north.
of combat.
Hu Ji and Mishilang who were stationed in Uliasudai were also transferred back, and their replacements were deputy regimental commander Cao Chao and deputy political commissar. Yin Bingwei, who had previously served as his guard company commander, was transferred to Kulun and promoted to the regiment.
long.
In terms of the chief officer configuration of the eastern front force, that is, the offensive force in the Shengjing direction, Zhao Xin planned to promote Mi Shilang to brigade commander, leading four regiments to be responsible for the attack direction from Changchun to Changtu; Pan Xiucheng was transferred from the Hunchun direction.
Li was promoted to brigade commander and led three regiments, responsible for the attack direction from Changtu to Weiyuan Fort Gate.
Lu Shoushan went to Hunchun and was promoted to the brigade commander of the garrison brigade. In addition to stabilizing the newly acquired Tumen River line, he was also responsible for the flank attack on Shengjing from the direction of Changbai Mountain.
Chen Jishan, the first master to serve as the commander of Zhao Xin's guard company, was transferred from Mergen City to Jilin Wula as the commander of the garrison regiment.
Li Rui's position was promoted one level and he became the chief of staff of the Eastern Front Army. When Deng Fei was absent, he was acting in charge of all daily and emergency combat affairs.
In addition to the chief officers, the political commissars and deputies of each regiment have also been changed. All promoted officers will first report back to Fuldan City, and then participate in an officer training course hosted by Zhao Xin before they can perform their duties.
Zhao Xin is so troublesome! He doesn't want to delegate power in the military, so no one can help him. He has to consider not only everyone's personality, military experience, but also everyone's faction. There are a lot of personnel files for him.
I felt dizzy watching it.
After he finally finished the adjustment plan and was rubbing his sore temples, there was a knock on the door outside the study.
"Come in."
The door opened silently, and A Miao walked in carrying a tray with ginseng soup.
Zhao Xin took the bowl habitually, took a sip, nodded with satisfaction, and was about to ask what to eat for dinner. He saw A Miao's face flushed, looking like she wanted to say something but was hesitant. So he asked casually
Said: "What's wrong?"
"Well...after this month..."
"Huh? What do you want to say? What happened after this month?"
"After this month, I will be eighteen." A Miao said in a lower voice, her face turned red, her head drooped, and her fingers dug at the bottom of the tray.
"Oh. What gift do you want?" Zhao Xin nodded nonchalantly. After a while, he suddenly came to his senses, slapped his forehead and said loudly: "Oh! I understand, I understand!"
A Miao said shyly and foolishly: "What do you know?"
Zhao Xin chuckled, put down the bowl, stood up, walked to the opposite side of the table, leaned over and gently hugged the other person's slim waist...
