blood feud

In the busy time, time passed quickly, and in the blink of an eye, at the beginning of May 1938, Lan Caiqin sent a telegram:

"Zhang Jingfu has already set off with a fleet of 7 freighters and 8 ships. On the way, he passed through Hawaii, Midway Island, Guam, and Chiwei Island to replenish fresh water, and then turned north and entered the Yellow Sea to go home."

"The entire journey is estimated to be 8000 nautical miles, or 15000 kilometers. Considering the need to stay at Midway Island for one month to complete the outfitting of eight ships, it is estimated that the entire journey will take two months."

"Wow, Sister Caiqin and the others are really amazing, they brought back 8 warships for us in no time!" Xiao Lamei was in charge of the telegram from the international team, so as soon as she received the telegram, she rushed to Bai Shujie's office to report the good news .

Zhao Jinxi, Gan Tong, Lu Ming and the heads of various departments gathered around to watch the news, and the entire headquarters erupted in cheers.

"You should be happy indeed!" Bai Shujie took the telegram and said: "The work of the international team outside has been very effective, which shows that our Feilong Expeditionary Army is an army that cannot be dragged down. Now, we have a more urgent task. The task is to complete various infrastructure constructions and welcome our fleet back home!"

"Lamei, you need to take more time to look at the second phase of the Heiling villa area. This time, we will have thousands of overseas employees. We must let them live well. Don't lose talent to Lan Caiqin and the others. Otherwise, it will be difficult for them to work outside in the future!"

"Jin Xi must urge the soldiers in front to strengthen their vigilance. With such a large fleet, after entering the Yellow Sea from Chiwei Island, it has to pass through Okinawa Island, Hong Kong, Shanghai, and the ocean near the Jiaodong Peninsula. It takes a day and a night to sail. Such a long time , the little devil will definitely find out. We must be careful of the little devil attacking us from the land."

"Lu Ming must do a good job in coordinating all aspects, and at the same time check the progress of the second phase of the construction of the air force base. The planned 20 large hangars for the Jiufengshan bomber must be completed on time."

"The construction of radar base stations from south to north must be completed as soon as possible, and then joint testing will be carried out. Ensure that the signal can cover the entire sea area around the Korean Peninsula, so that there are no obstacles to our air early warning and long-distance communication, and at the same time allow the fleet to enter the Yellow Sea area to navigate."

"Gan Tong's main task is to adjust the troops directly under our headquarters, especially the railway air defense regiment and the air defense battalion of the headquarters; to order the Flying Tiger Squadron of Jiangnan Airport to dispatch a three-aircraft formation to cruise over the Yellow Sea every day. On the one hand, observe the enemy's situation, and on the other hand, confuse the enemy; as for other departments, they must move quickly."

"My next main energy is, on the one hand, to urge the Cangyunli Shipyard to renovate the two destroyers; on the other hand, to urge the construction of the deep-water wharf; thirdly, to urge the scientific research work to ensure that the radar and communication equipment are put on board on time; fourthly. It is to step up the development of new weapons."

With a clear hope, everyone has a goal in their hearts, and all work has accelerated.

The hull renovation of the Chunfeng destroyer has been completed. The original relatively slender bridge has been improved, mainly to be able to withstand the blowing of typhoons of level 10 or even level 12.

Bai Shujie knew in his heart that the "Kamikaze-class" destroyer was the first time the little devil used a steel bridge, and all of them were broken or cracked by strong winds.Now that it's in his hands, this kind of oolong thing must never happen.

The most important thing is that the original bridge has become the current two bridges.With a solid and reliable bridge, a re-improved radar has been installed.

The radar installed this time is based on the "Type 13 radio wave detector" that the little devil could only invent three years later, combined with the "cottage" technology of Boeing's fire control radar system, temporarily named "DW2 Type" Fire Control System Detector".

The radar that the little devil invented three years later is basically a waste.The only advantage that Bai Shujie absorbed was that the radar of the little devil had optimized the circuit to the extreme, and the volume was very small.

As for performance, don't mention any performance at all.

It was originally installed on the battleships "National Treasure" Yamato and Musashi, and the only function it played was to tell the captain that "a battleship is coming, but I don't know where it is, how far it is, and how fast it is." !"

After processing by Bai Shujie, this mobile search radar is a common model for land, ships and submarines.It consists of two parts: X-wave transmitter and reflected wave receiver.Its advantage is small size: height 480mmx width 560mmx length 720mm; light weight: net weight 25 kg.

At present, it has been installed and tested at Jiangnan Airport, Miaoxiangshan Air Force Base, and Jiufengshan Airport. Compared with the second-generation radar, the performance has been greatly improved, and the stability, sensitivity, and accuracy have greatly increased.

It has become a finalized product, and the technical core of it is naturally a Class A top secret. In fact, only Bai Shujie knows it.

The fire control system (also known as the firing director) mainly includes three parts: 4 sets of dw2 fire control system detection radars, 2 sonar detectors, and 4 Swedish optical range finders.

Ship-borne type: mainly search for ships and aircraft within 120 kilometers, determine the azimuth and distance, and determine the relationship between the enemy and us.

Airborne version: remove the sonar sounder and optical range finder, and replace it with an echo frequency analyzer.It is mainly to search for moving targets within a range of 120 kilometers, determine the course and distance of the opponent; judge the relationship between the enemy and the enemy according to whether the opponent has airborne radar and radar frequency signals.

The fire control system is located in the command post of the second bridge at the stern. There are 8 operating platforms and 2 commanding platforms. They are composed of 19 personnel, including the Guantong Commander, the Gunner Commander, the Radar Soldiers, the Sonar Soldiers, and the Ranger Soldiers.In addition to rangers, radar soldiers provide shooting parameters for main guns, secondary guns, anti-aircraft guns, and Phalanx.

In this transformation, Bai Shujie learned the lessons of the previous Feilong 302 ship and completely separated the ship command, gun command, radar command, and power command.

The command station on the first bridge is composed of 37 people in total, including the captain, chief engineer, chief navigator, and personnel working on the map, compass, and radio.

In other words, until the last moment, the first duty of the commander of the first bridge is to control the battleship, analyze the situation he is facing, or choose to fight or escape.

The first duty of the second bridge command post is to observe the enemy's situation, report the situation to the first bridge at any time, and then undertake the battle command task according to the captain's order.

Therefore, in this transformation, a total of 4 rangefinders and 5 radars were installed on the battleship (1 communication radar was controlled by the first bridge, and 4 fire control radars were controlled by the second bridge).

Bai Shujie knew that the bastards under him had never read any advanced theoretical books. In order to be easy to master and use, he took the trouble to compile a set of "Azimuth Conversion Table", "Speed ​​Conversion Table", "Distance Conversion Table" ".

There are only three goals: to find the enemy at the farthest distance, to determine the enemy's location in the shortest time, and to shoot the first shell with the fastest action!

Only on the battlefield can we truly understand the true meaning of "time is life"!

Now that the command system is clear, what Bai Shujie needs to make the final decision is the equipment of the weapon system.

After repeated demonstrations in the past few months, Bai Shujie still decided to put the speed of the battleship first, and cancel the original demining system and laying system.

At the same time, all the original four g-type single-tube 4mm naval guns were discarded. These single guns have their own turrets, which are stupid and difficult to use, and take up a lot of weight.As for the imp's two single-barreled 120mm anti-aircraft machine guns, Bai Shujie directly ordered them to be moved back to the steelworks.

After refitting, the brand-new Spring Breeze, the final result is that the waterline armor has become 360mm, and the frontal armor of the conning tower is 380mm.The engine room and the ammunition compartment have increased the isolation compartment, and the displacement has increased by 500 tons.The weapons and equipment are as follows:

标准排水量1790吨，满载排水量2540吨。主甲板安装双联装dw203mm主炮1座，后甲板安装双联装dw88mm高平两用炮2座，五管dw30mm密集阵4座，双联533mm鱼雷发射管2具。声纳系统两副。航速39.3节；舰员148人。

Bai Shujie is very clear about the future role of the Chunfeng destroyer: it does not aim at combat, nor does it undertake anti-submarine missions.Instead, it exists as the vanguard of the fleet, responsible for scouting and pathfinding.Take advantage of your lightness and speed to take the lead in front of the formation.

The original Flying Dragon No. 301 and No. 302 destroyers were later clearly stated in Lan Caiqin's telegram that they would be handed over to Capone's "pirates" for use.So this time it was just a fix, and no more changes were made.

Considering that pirates will not fight frontally, mainly for air defense and escape, so two 533mm torpedo launch tubes in double installation, 2 torpedoes; 12 No. 1 mines; 20 pieces.These things are not needed, and they are all disassembled to reduce weight.

Therefore, after the overhaul, the destroyers Feilong 301 and 302 are now equipped with three radar antennas and a fire control system. The weapon system is simple:

主甲板安装双联装dw203mm主炮1座，后甲板安装双联装dw88mm高平两用炮2座，五管dw30mm密集阵8座。航速38节，续航8500公里/14节。被动式声纳系统一副。舰员118人。

Because the fleet commander Zhang Bingyang did not know the specific situation, he saw that the destroyers Feilong 301 and 302 had dismantled all the torpedoes and depth charges, and raised objections at that time:

"Commander-in-chief, if you make such a change, the speed will naturally increase, but it will not work. The little devil has a lot of submarines. Once attacked by submarines, the current two destroyers will not be able to expel them at all. If you escaped, it is impossible to take on the task of guarding!"

"You're right!" Bai Shujie smiled slightly: "These two ships are no longer called destroyers, but deep-sea patrol ships. The main purpose is to be able to escape quickly. Of course, since you are the commander of the fleet, such things are naturally not For your use."

Zhang Bingyang was dumbfounded when he heard this: "Then what should I use? Could it be that every time I go out there is only a cruiser and a destroyer Chunfeng, and I don't even have flank cover, so it's not a living target for the little devil!"

"Whether the ship is acquired or not is not the main issue!" Bai Shujie still said with a smile: "What I am worried about is how many warships can you command to fight together? 3 ships? 6 ships? I have an idea that Feilong 201 also needs major changes. Once, and it’s too embarrassing for you to use such a flagship, at least you have to get a flagship of tens of thousands of tons!”

Zhang Bingyang felt a little dizzy when he heard this: "I have heard of the [-]-ton giant ship, but I have never seen it. It is said that the battleship and aircraft carrier of the little devil are such big guys. It is said that the aircraft carrier Chicheng that you led the air force to attack last time has several Ten thousand tons. I really wanted to drag that guy back, what a pity!"

After all, what happens next, let's see the breakdown in the next chapter.
