The two battleships, Crimson and Frost, looked at the electromagnetic cannon test in Yiwu with envy.

Seeing this new weapon, they instinctively thought that if their 380 mm main gun could also reach the muzzle velocity of 7 times the speed of sound, how terrifying would the range and power be?

When Yiwu's test came to an end, Ning Shuang directly hugged Mu Feng's arm with an excited face:

"Commander, Commander, when will Frost and Crimson be replaced with this cannon?"

Mu Feng was a little helpless: "I also want to change the electromagnetic cannon for you, but the electromagnetization of the large-caliber main gun is too difficult to achieve, and you can't change it for the time being, so you can only replace the secondary gun for you first." ”

Crimson lowered her head in contemplation when she listened, and Ning Frost asked directly, "Why?" ”

Mu Feng sighed: "The first is that we can't make large-caliber electromagnetic guns now, and the second is that our most powerful power system at present can't meet the energy needs of large-caliber electromagnetic guns." ”

Neptune next to him explained to Frost: "When the caliber of the cannon is larger, the weight of the shells will increase exponentially, and the energy consumed will also increase in equal proportions.

"A shell of about 400 mm weighs about 20 times as much as 155 mm, and it takes almost 20 times as much energy to accelerate to the same speed.

"Even if you give up the hypersonic speed of the electromagnetic gun, just change your main gun to an electromagnetic drive while maintaining the current rate of fire, it will require a million kilowatts of power supply."

Ning Shuang blinked: "Then let's change to a million-kilowatt power system!" ”

Neptune almost squirted: "How can it be that simple!" The electric power of the nuclear-powered aircraft carrier I expect is only 400,000 kilowatts, which is the level of a land nuclear power plant! ”

Ning Shuang flattened her mouth with an embarrassed face: "Forehead...... I think I'm asking a stupid question......"

Crimson next to him followed: "I just made a simple calculation, if the muzzle velocity is reduced to 3 times the speed of sound, our current 280,000 kilowatt power system will be converted into electrical energy, and it can only support a rate of fire of 30 rounds per minute at most, which is about one-third of the current one, and the combat effectiveness will be reduced." ”

Sirius squinted his eyes and said: "With our current level of science and technology, the current energy system and energy storage system cannot support this level of electromagnetic cannon for the time being, and the difficulty of scientific research is extremely high, so it is not recommended to carry out a large-caliber electromagnetic cannon project in a short period of ......time."

Frost was deflated at Sirius's words, looking down at the ground, not knowing what he was thinking.

Mu Feng raised his hands and touched the crimson and frosty hair respectively:

"You two don't have to be too discouraged, now the armor-piercing ability of the 155 mm electromagnetic gun has surpassed your previous 380 mm main gun, and I will replace it as a secondary gun."

Ning Frost raised his head: "Then are you going to dismantle our main gun?" ”

"Of course you can't dismantle it!" Mu Feng immediately shook his head, "Your main cannon is still a very useful thing, and I have another plan that needs to use your main gun. ”

Frost flattened her mouth: "Okay." ”

At the end of the test in Yiwu that afternoon, Mu Feng gave a simple transformation to the crimson condensation, dismantling their original 8 sets of 130mm secondary guns and replacing them with electromagnetic guns.

4 sets of twin 155-mm electromagnetic guns, mounted on the four corners of the integrated central bridge, and 6 sets of twin 76-mm electromagnetic guns, 3 on each side of the central bridge.

Mu Feng stayed in the fortress area for one night, and slept with the softest crimson for the first time in a long time.

The next morning, Mu Feng took Sirius and Neptune on a plane to the temporary residence of the French Command.

When they arrived in a new place, the two Sirius sisters, out of a professional habit, immediately began geographic mapping and information collection and sorting through the J-20 and early warning aircraft.

Mu Feng was also happy to let them move freely, and went to the temporary fleet in Liaoning by himself.

At present, Liaoning, Kunlun, Changchun, and Lanzhou are still together, and they continue to carry out pre-relocation inspections of those abandoned human towns.

Mu Feng took a helicopter to the deck of the Liaoning, and the projection of Liaoning's ship mother emerged, with a subtle smile on her face:

"The commander suddenly went back the day before yesterday, and I thought there was something important, but it turned out that he had gone to build."

Mu Feng thought to himself, isn't construction the most important thing to the commander?

But he didn't say this, just smiled a little awkwardly, and then changed the subject:

"How's it going on your side? How long will this comprehensive inspection last? ”

"At least ten days and half a month......," Liaoning sighed slightly, "Because of the problem of the output of marine resources, the distribution of the Jianniang military port is very scattered, and the corresponding human life is also relatively scattered, all of them are small and medium-sized towns, and all of them have to be searched one by one." ”

Mu Feng frowned slightly: "This is indeed a bit troublesome, these small towns are scattered and it's not easy to manage, if only they could be concentrated." ”

Liaoning thought for a while: "This is indeed a problem, in the past, their living pattern was naturally formed, and if they move together in the future, it will be more convenient to manage and develop construction."

"The population and the size of the city have gone up, and the industry can have great development, but now their industrial level is too low, the power system has not been popularized, and the human ship has just begun to burn coal.

"Human beings are not lacking in creativity, but limited by the current level of industry, even a rudimentary armored cruiser cannot be built, and it will be of little help to the ship's command......"

Mu Feng nodded slightly: "I think you can talk to Li Sailiu and Vine about how to gather human beings together, I'm not good at this kind of thing, I'll go and change the electromagnetic cannon for Changchun and them!" ”

"Forehead......" Liaoning looked at Mu Feng's back, shook his head slightly, and muttered quietly with one hand on his cheek, "I shouldn't talk about this type of problem, what topic should I find next time?" ”

Mu Feng got into the cabin of Liaoning, found the rest room specially reserved for himself, called Changchun and Kunlun on the boat in turn, and replaced the main guns of the two of them with electromagnetic guns.

Changchun knew that it was inside the Liaoning ship, so he cooperated very honestly, and ran out after the transformation with a wink at Mu Feng, Kunlun is now in a workaholic state, and he will go back to work as soon as the transformation is completed.

Mu Feng finally called Lanzhou up. In the Battle of Deep-Sea France, Lanzhou has been able to take the initiative to hull, so now it is also possible to reforge her.

The reshaping of the hull has been done twice, and now it is considered a familiar road, and the recasting of the Lanzhou ship and the transformation of the electromagnetic cannon took a little more than an hour.

The appearance of Lanzhou was originally a more mature type, looking like a high school student, the appearance of the ship changed very little after the hull was reshaped, the height did not change, and the figure became better.

After changing the Lanzhou time, it was almost noon, Mu Feng stayed directly in the cabin of the Liaoning to eat, and when he returned to the bedroom to sleep for a while, he suddenly received a message from Nanchang:

"Commander, at 8 o'clock in the morning, the early warning radar of the First Military Port detected that about 300 kilometers to the northwest, a fleet was moving at high speed.

"At that time, it seemed that this fleet was approaching the First Military Port, so I sent an AWACS aircraft to keep an eye on it.

"A few minutes ago, they were only 100 kilometers away from the entrance to the eastern strait of the First Military Port, and I radioed them about their identities and their intentions.

"I received a reply that Bismarck, the commander-in-chief of the German Command, led a team to visit the Royal Navy and then asked about our identity, how should I answer?"
