So, what exactly does Bai Fei want to exchange for the system to modify the ship?

He had already planned for this.

Because they are civilian ships converted into warships, compared with real warships, there are some inherent defects. For example, the displacement is small, the thickness of the first class and the lateral chord steel plate is insufficient, the defense is poor, and so on. If in a battle, even if the hull of the ship is only hit by one shot, the entire ship may fall apart and sink, which is very fragile.

Therefore, if he wants to have the strength to compete with the Japanese army at sea, Bai Fei must work hard in other aspects, and in detail, there are basically three major directions to make up for the congenital shortcomings of rebuilding ships.

What are the three major directions?

First, of course, there is the optimization of power. He wants to ensure that after the completion of the transformation, the sailing speed must be fast enough, the so-called martial arts in the world are only fast and unbreakable, only fast enough, in order to advance and retreat freely, and always be invincible;

Second, the ability of early warning and defense should be improved. Regarding this point, Bai Fei plans to install an early warning system on each modified ship, not only for sea-to-air radar warning, but even for underwater sonar warning to prevent sneak attacks by submarines of little devils;

Third, the attack capability is improved. In this regard, Bai Fei is generally ready to install 3 different weapons systems on each ship. One of them is the torpedo launch system, which is used as the main means of attack. The second is a naval gun for long-range attacks. The third is a defensive run that serves as a short-range weapon for short-range defense against air and sea.

So, Bai Fei specially selected an engine used in a French destroyer on the system, this French destroyer is called "Terror", which is said to be the fastest destroyer in the world, with a speed of about 45 knots per hour (that is, more than 80 kilometers), and the maximum speed can even reach 100 kilometers per hour. You must know that in the whole world nowadays, the speed of most warships and ships is only more than 30 knots at the fastest, so this speed can be said to be very fast, and Bai Fei is very satisfied with this. As the saying goes, can't you run if you can't beat it? With such a strong power system, even if you escape, it will be a complete ride, and no one can catch up.

In terms of defense and early warning, when Bai Fei selected the air-to-sea early warning radar, he chose a radar with a detection range of about 100 kilometers; As for the underwater sonar detection and early warning equipment, Bai Fei picked for a long time, and finally selected a Soviet-made sonar detector with a detection depth of 700 meters and a detection distance of 60 kilometers. Of course, none of these are the most advanced in the system, but they are still better than most early warning detection devices of this era. On top of that, they are good value for money, and the merit points required to redeem them are relatively small compared to more advanced equipment.

In terms of weapon selection, Bai Fei attaches great importance to it, and even at the cost of a huge amount, he has to exchange weapons that have a crushing advantage compared with the weapons of this era. Therefore, when he chose the main battle weapon ---- torpedo, he directly chose the most advanced supercavitating weapon from Russia - the "Tempest" torpedo.

In general, this torpedo is designed to use the cavitation phenomenon caused by the extremely fast movement of objects under water, and turn harm into advantage. The designers installed a cavitation generator on the head of the torpedo, which was in the shape of a circular or oval flat disk, and tilted forward to form an "angle of attack" to generate lift to support the front of the mine. When the torpedo moves in the water, the air is expelled from the head and covered by bubbles on the surface of the minebody, forming a "supercavitation". Therefore, its water resistance is very small, and its speed is very high, far exceeding that of ordinary torpedoes.

If you want to say that Lao Maozi is researching weapons, I really don't say it. How powerful is this torpedo? It is said that it is now, but it is put on until Bai Fei crosses, and this torpedo is also the leader of the torpedo world. Although it has a range of only 15,000 meters, its maximum attack depth is only 400 meters. However, it travels at speeds of more than 200 knots.

What is the concept of verse 200? It's almost 400 km/h! Don't say that the torpedo will explode, such a high speed is a light collision, and ordinary ships can't bear it.

After Bai Fei read the parameters of this torpedo again, he was also taken aback, and then he was determined to exchange it at any cost.

After selecting the torpedo, Bai Fei chose the Russian-made AK176 76mm caliber naval gun, which has a range of 17 kilometers, and the caliber belongs to the medium caliber of naval guns, although it is not the most advanced, but it has a characteristic, the failure rate is particularly low, and there is another point, this kind of gun has a very high rate of fire, simple operation, even if it is operated manually, within a minute, it can also fire more than 30 shells.

In addition, in the selection of short-range defense guns, Bai Fei directly selected the domestic 1130 close-in defense gun, which is an 11-barreled 30 mm caliber Gatling gun, with a maximum rate of fire of 11,000 rounds per minute and an effective firing range of 5,000 meters.

This kind of artillery will not be introduced much here, friends who have watched "Operation Red Return" should be familiar with the scene of the Chinese warship striking the incoming rocket. That's pretty brutal!

In order to increase the flexibility and control performance of the 1130 close-in defense gun, Bai Fei even prepared a fire control radar for it, and worked with it to believe that the 1130 will definitely shine in terms of defending against the enemy.

In addition, Bai Fei also prepared a set of radio and wireless communication equipment for each ship.

After everything was ready, early the next morning, everyone came to Xiuying Port as promised.

Bai Fei led Fu Nianzu to a heavily guarded warehouse near the port, and when he opened the warehouse door, he saw that it was full of all kinds of weapons and equipment.

Of course, this is Bai Fei's exchange with the system when no one is there at night.

Fu Nianzu and the others were very surprised to see the mountains of equipment in front of them, but Bai Fei didn't explain much about it, but just led them to briefly introduce the things in the warehouse one by one, and then solemnly handed over the booklet containing the introduction, performance specifications, parameter indicators and other contents of each equipment to Fu Nianzu, and told them to keep it absolutely confidential.

Fu Nianzu and several other experts nodded solemnly, and soon immersed themselves in the booklet.

The modification of a large ship is not a simple matter. As Fu Nianzu said, it is necessary to go through a series of preparations such as demonstration, surveying and mapping, drawing, design, etc., and because Bai Fei has too much equipment for this renovation and new addition, everyone is even more afraid to be sloppy.

It wasn't until a week later that Fu Nianzu and the experts came up with an accurate reconstruction plan, and Bai Fei was so happy that he ordered the reconstruction work to start immediately.

During this period, Bai Fei was also actively establishing his own navy, and he ordered people to select from the military police regiment and Li Shuyang's thousands of subordinates, and finally selected more than 200 people.

Not only were all of them proficient in water, but they were also literate, and most importantly, they had all sailed on the seas, and even a few of them had been naval soldiers of the Nationalist Government before.

For example, Bai Fei once rescued two wounded people in Nanjing, one is named Sun Kai and the other is Zhang Wenhao. They used to belong to the Central Navy, and they also held more important technical positions on warships, but later the Central Navy in order to delay the Japanese attack, in Jiangyin and other places sunken ships and locked the river, and destroyed all the good naval ships, Sun Kai and Zhang Wenhao were also from a naval soldier, were incorporated into the army sequence for the defense of Nanjing, and then later, everyone already knows, after they were injured, they were taken out of Nanjing by Bai Fei at risk, and after recovering from their injuries, they were taken into account by Bai Fei.

There are many examples like Sun Kai and Zhang Wenhao, Bai Fei didn't care about it before, this time in order to organize the new navy, he sorted out the soldiers under his command, and found that in addition to Sun and Zhang, there are many naval talents with similar experiences to them.

So Bai Fei immediately planned to use them as the backbone and slowly expand the navy.
