Time flies quickly in the busyness, and in a blink of an eye, in early May 1938, Basket Caiqin sent a telegram:

"Zhang Jingfu led the fleet to depart, with 7 freighters and 8 ships. On the way, it passed through Hawaii, Midway, Guam, and Chiwei Island to replenish fresh water, and then turned north into the Yellow Sea to return home. ”

"The entire journey is estimated to be 8,000 nautical miles, or 15,000 kilometers. Considering that a one-month stay at Midway was required to complete the outfitting of the eight ships, it was expected that the entire trip would take two months. ”

"Wow, Sister Caiqin, they are so powerful, they will get us back 8 warships at once!" Xiao Lamei was in charge of the international team's telegram, so as soon as she received this 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 all gathered around to watch the news, and the entire headquarters was full of joy.

"You should be happy!" Bai Shujie took the telegram and said: "The work of the international team outside is fruitful, which shows that our Flying Dragon Expeditionary Force is an army that cannot be dragged down or defeated. Now, we have an even more urgent task to complete the construction of various infrastructure and welcome our fleet home! ”

"Lamei, you have to take time to see the second phase of the Heiling Villa Area recently, we will have thousands of overseas employees this time, we must let them live well and eat well. Don't embarrass them for the basket, otherwise they won't be able to work outside in the future! ”

"Jin Xi must urge the soldiers in front to strengthen vigilance. After entering the Yellow Sea from Chiwei Island, our fleet had to pass through Okinawa, Hong Kong, Shanghai, and the waters near the Jiaodong Peninsula, and needed to sail for a day and a night. For such a long time, the little devil will definitely find out. Beware of the little devils flanking us from 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 base. The 20 large hangars for the scheduled Jiufeng Mountain bombers 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. Ensuring that the signal can cover the entire sea area around the Korean Peninsula allows us to have no obstacles to air warning and long-distance communication, and at the same time allows the fleet to enter the Yellow Sea area for navigation. ”

"Gan Tong's main task is to adjust the troops directly under our headquarters in place, especially the railway air defense regiment and the air defense battalion of the headquarters are all deployed in place; The Flying Tiger Squadron at Jiangnan Airfield was ordered to dispatch a three-plane formation to patrol over the Yellow Sea every day, observing the enemy situation on the one hand, and confusing the enemy on the other; As for the other departments, they must hurry up. ”

"My main energy in the next step, on the one hand, is to urge the Cangyunli Shipyard to renovate two destroyers; on the other hand, supervise the construction of deep-water terminals; The third is to supervise scientific research work and ensure that radar and communication equipment are on board and on board on time. Fourth, it is necessary to step up the research and development of new weapons. ”

With a clear hope, everyone has a goal in mind, and the pace of work is accelerated.

The hull renovation of the destroyer Chunfeng has been completed, and the original relatively slender bridge has been improved, mainly to withstand the blowing of a 10 or even 12 typhoon.

Bai Shujie knew in his heart that the "kamikaze-class" destroyer was the first time that the little devil used a steel bridge, and all of them had been blown off or blown apart by strong winds. Now that it is in his own hands, this kind of oolong thing must not appear.

The most important thing is that the original one bridge has become the current two. With a strong and reliable bridge, a reworked 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, and integrates the technology of Boeing's fire control radar system "copycat", and is tentatively named "DW2 Fire Control System Detector".

This radar, invented by the little devil three years later, is basically a waste. The only advantage that Bai Shujie absorbs is that the little devil's radar optimizes the circuit to the extreme, and the size is very small.

As for performance, not to mention anything at all.

At the beginning, it was installed on the battleships Yamato and Musashi, the "national treasures" of the little devils, and the only role it played was to tell Captain Sù that "a battleship is coming, but I don't know where it is, I don't know how far it is, and I don't know how fast it is!" ”

After being processed by Bai Shujie, this mobile search radar is a common model for land, ships and submarines. It consists of two parts: an X-wave transmitter and a reflected wave receiver. Its advantages are its small size: height 480mm× width 560mm× length 720mm; Light weight: net weight 25 kg.

At present, it has been installed and tested at Jiangnan Airport, Miaoxiangshan Air Base, and Jiufengshan Airport, which is much better than the performance of the second-generation radar, and the stability, sensitivity, and accuracy have increased significantly.

It has become a stereotyped product, and the technical core of it naturally belongs to Class A top secret, in fact, Bai Shujie understands it alone.

The fire control system (also known as the shooting commander) mainly includes three parts: 4 DW2 fire control system detection radars, 2 sonar detectors, and 4 Swedish optical rangefinders.

Carrier-based type: It is mainly used to search for ships and aircraft within 120 kilometers, determine the azimuth angle and distance, and determine the relationship between friend and foe.

Airborne type: the sonar detector and optical rangefinder are removed, and the echo frequency analyzer is replaced. The main thing is to search for moving targets within a range of 120 km, determine the course and distance of the opponent; According to whether the opponent has airborne radar and radar frequency signals, the relationship between friend and foe is determined.

The fire control system is located in the second bridge command post at the stern of the ship, which has 8 operating platforms and 2 command platforms, which are composed of a total of 19 people, including the chief of observation and communication, the chief of gunners, radar troops, sonar troops, and rangefinder troops. In addition to the rangefinder troops, the radar troops provide firing parameters for the main guns, secondary guns, anti-aircraft guns, and phalanxes.

In this transformation, Bai Shujie learned the lessons of the last 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 a total of 37 people, including the captain, chief engineer, chief navigator, and personnel working on the map, compass, and radio.

That is to say, until the last moment, the first duty of the command platform of the first bridge is to control the battleship, analyze the situation they are facing, or choose to fight, or choose to 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 assume the combat command task according to the order of the captain.

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

Bai Shujie knew that none of the bastards under his command had read any advanced theoretical books, so in order to make it easier to master and use, he took the trouble to compile a set of "Azimuth Conversion Table", "Speed Conversion Table", and "Distance Conversion Table".

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

On the battlefield, you can truly understand the true meaning of "time is life"!

The command system has been figured out, and what Bai Shujie needs to make the final decision now is the equipment of the weapon system.

After repeated arguments over the past few months, Bai Shujie still decided to put the speed of the warship in the first place and cancel the original demining system and minelaying system.

At the same time, the original 4 G-type single-barreled 120mm naval guns were all abandoned, and these single guns had their own turrets, which were stupid and difficult to use, and also occupied a lot of weight. As for the imp's 2-seat single-barreled 7.7mm anti-aircraft machine gun, Bai Shujie directly ordered it to be moved back to the steel mill and reinforced.

After the modification, the new Chunfeng turned out to be 360mm for the waterline armor and 380mm for the front armor of the conning tower. Isolation compartments were added to the engine room and ammunition compartment, and the displacement was increased by 500 tons. The armament is as follows:

Standard displacement 1790 tons, full load displacement 2540 tons. One twin DW203mm main gun is installed on the main deck, two twin DW88mm high-level dual-purpose guns, four five-barreled DW30mm phalanxes, and two twin 533mm torpedo tubes are installed on the rear deck. Two sonar systems. The speed is 39.3 knots, and the crew is 148.

Bai Shujie's positioning of the future role of the Chunfeng destroyer is very clear: it is not for combat purposes, nor does it undertake anti-submarine missions. Instead, as the vanguard of the fleet, he was responsible for reconnaissance and pathfinding. Take advantage of your lightness and speed to take the lead in front of the formation.

The original Wyvern 301 and 302 destroyers were to be given to Capone's "pirates" in later telegrams. So this time it's a fix, and no more changes have been made.

Considering that the pirates would not fight head-on, mainly air defense and escape, 2 twin 533mm torpedo tubes and 12 torpedoes; 20 mines No. 1; 2 deep bomb projectors, 2 slide rails, 36 deep bombs. These things are not used, and they are all dismantled to reduce weight.

Therefore, after the overhaul, the Flying Dragon No. 301 and No. 302 destroyers are now adding three radar antennas and installing a fire control system, and the weapon system is simple:

One twin DW203mm main gun is installed on the main deck, two twin DW88mm high-level dual-purpose guns are installed on the rear deck, and eight five-barreled DW30mm phalanx guns are installed. It has a speed of 38 knots and a cruising range of 8,500 km / 14 knots. A passive sonar system. The crew is 118 people.

Because the commander of the fleet, Zhang Bingyang, did not know the specific situation, and when he saw the destroyers of Feilong No. 301 and No. 302 dismantling all the torpedoes and depth charges, he raised objections at that time:

"Commander-in-chief, if you change it like this, the speed will naturally go up, but it won't work, the little devil has a lot of submarines. Once attacked by a submarine, the current two destroyers will not be able to expel them at all, but will have to escape by themselves, and it is impossible to undertake the escort mission! ”

"You're right!" Bai Shujie smiled slightly: "The current two are not called destroyers, they are called deep-sea patrol ships, and the main purpose is to be able to escape quickly." Of course, since you are the commander of the fleet, such a thing is naturally not for you. ”

Zhang Bingyang was dumbfounded when he heard this: "Then what do I use?" Could it be that every time I go out, there is a cruiser and a destroyer of the Chunfeng, and there is no flank cover, and it has not become a live target for the little devils! ”

"Whether the ship gets or not is not the main problem!" Bai Shujie still smiled and said, "What I'm worried about is, how many warships can you command to fight together?" 3 ships? 6 ships? I have an idea, the Feilong 201 also needs to be overhauled, and it's really embarrassing for you to use such a flagship, at least you have to get a flagship of tens of thousands of tons! ”

Zhang Bingyang was a little dizzy when he heard it: "I've heard of the 10,000-ton giant ship, but I've never seen it." It is said that the battleships and aircraft carriers of the little devils are such big guys, and the aircraft carrier Akagi, which you led the air force in the last attack, is said to have tens of thousands of tons. I really wanted to drag that guy back, what a shame! ”

After all, what happens next, let's see how it will be broken down next time.
