Lin Xianxin asked Li Kongrong to preside over the meeting, Zhou Yingcong was not surprised, but Ma Deji and Chen Wenlin were a little surprised, but they were only surprised, how to carry out their follow-up work, and now they really need to make a more complete plan.

Li Kongrong was also not polite to Lin Xianxi's humility, he said: "Shipbuilding and aircraft are the focus of the Navy's reconstruction, and both of these tasks have two parts. In the case of shipbuilding, design is one part, and where to build is another. The former needed to go to Alaska to survey the cruise ship, and only after surveying and mapping did we know that if it was changed, we bought a modification drawing of the USS Hundred-Eyed aircraft carrier in the UK, but the value of this drawing was limited. In general, all the design of the aircraft carrier revolves around the carrier-based aircraft, and how to design it to fit more aircraft, how to design it to be more conducive to aircraft attack, and how to design it to protect this floating airfield, then how the aircraft carrier should be designed.

We had no money, so we had to rely on capturing the enemy's cruise ships to refit the aircraft carrier, which was generally considered to be too thin and poorly protected, and was accidentally sunk by the Japanese. I don't see it that way, I spent a lot of time talking about the aircraft carrier officers of the British Navy, talking about the protection of the British converted aircraft carriers. When I asked this question, the British didn't care, they said that an aircraft carrier of about 20,000 tons is the level of protection of a cruiser, and it will be thanks to God if it does not sink with two torpedoes.

Later, I re-analyzed the Japanese Navy, and I felt that the Japanese Navy's carrier-based aircraft bombardment methods were emphasized, to be specific, the Japanese were best at paying the most attention to torpedoes, and they did not attach importance to dive bombing, believing that torpedoes were enough to sink the enemy's ships. And the bombs used for the dive also reflect the deep-rooted thinking of the Japanese Navy's surface artillery warfare, how to say it? That is to say, the general delay time of these dive bomb tubes is 0.2 seconds, and the purpose is to allow the bomb to explode in the core compartment, which in surface artillery warfare is to penetrate the core compartment of the enemy ship, either to damage the boiler room or power system, or to detonate the ammunition depot.

In fact, aircraft carrier battles are not like this, except in the strait, aircraft carriers will only engage aircraft carriers, or engage shore-based aircraft, and the most important thing in the attack is to paralyze the take-off and landing of the opposing aircraft, rather than to shoot bombs into the core module. However, in the core cabin, our power system will be cross-arranged, the ammunition depot will also thicken the steel plates, and the gasoline depot will not only focus on protection but also add a concrete shell, but the hangar is a weak point in defense, for example, during the maintenance of the aircraft, if a dive bomb explodes in the hangar, the whole ship may be sunk.

In the emphasis on the defense of dive bombers and torpedo bombers, we naturally choose to defend against torpedoes, preferring to be hit by five bombs rather than hit by one, so the anti-torpedo compartment below the waterline is the key point of the aircraft carrier design, and it is best for the shipyard to understand the American TDS mine protection system and then install it on the aircraft carrier. The displacement of the aircraft carrier modified by the Tatsuda Maru should be at least three or more aviation torpedoes and then sink. ”

TDS is something Ma Deji knows, although Jiangnan Shipyard has never built large ships, but he once studied at MIT. Seeing that Li Kongrong had such an opinion on the design and protection of aircraft carriers, his eyes blinked several times in a row - Lin Xianxi did not see the wrong person, although Li Kongrong was born in an engine, he also knew how to build ships.

"It's just that if the TDS is designed to be too thick, if it is placed inside, it will affect the space of the ship, and if it is placed outside, it will affect the speed, with the displacement of the Tatsuda Maru, how much power should we use?" Ma Deji asked.

"Six pots and three axles, 120,000 horsepower." Li Kongrong has long considered the power system, the current displacement of the Longtian Pill is less than 17,000 tons, and the tonnage will definitely increase after the modification, but it is only about 20,000 tons, and 120,000 horsepower is enough.

"If it's 20,000 horsepower per pot, maybe the pressure will be more than 30 kilograms." Ma Deji said. He knew that the British aircraft carrier Ark Royal, which had just been launched this year, was a six-pot three-shaft, but it only had 100,000 horsepower, and if the six-pot wanted to achieve 120,000 horsepower, the boiler pressure should exceed 30 kilograms and the temperature should exceed 300 degrees.

"Don't be afraid, we can pick the boilers of the British and Americans, and many of the boilers of American battleships have a boiler pressure of more than thirty kilograms." Li Kongrong said, "The design should be completed earlier, so that the boiler can be ordered earlier, and the sooner the boiler is ordered, the cheaper the price." ”

After talking about the power, Li Kongrong said again: "I forgot to say just now, in addition to anti-torpedo, the fire prevention of aircraft carriers is also extremely important, the gasoline pipeline must be emptied of the residual gasoline in the pipeline before the battle, and then it can be filled with carbon dioxide, and the same is true for the gasoline depot, once the enemy must be filled with carbon dioxide to prevent fire; It is also necessary to be equipped with a large number of foam fire extinguishers and lighting pumping devices with independent power throughout the cabin to prevent the cabin from being lit and extinguishing the fire once the power system is interrupted. In general, lightning protection is the first, fire protection is the second, and anti-dive bombs are in the third. If the gasoline depots, ammunition depots, and fireproofs are all well designed and the power is cross-arranged, the dive bomb will be useless.

It is also important to have more aircraft. The hangar is designed as double-decker as possible, with two inboard lifts and closed hangars on the lower floor, and two outboard lifts on the upper floor, but it is required to lift two aircraft at the same time. The uppermost flight deck is required to be as long as possible, and the Tatsuda Maru is only 178 meters, so we have to find a way to lengthen it and extend the flight deck to more than 200 meters, preferably to 220 meters. ”

"This," Li Kongrong said about the design requirements of the aircraft carrier, and Ma Deji kept it in mind while remembering that he didn't have much concept of a double-decker hangar, but the Japanese Canglong aircraft carrier could do a double-decker hangar, and Ma Deji believed that Tatsuda Maru could do it, but if he wanted to lengthen the 178-meter ship to 220 meters and increase it by more than 40 meters, he felt that he was in a difficult situation. "Brother Hansheng, this is too long, I'm worried that it will not be stable."

"The longer the deck, the more planes will be released in a single flight, and the more planes there are, the more likely it is to carry out a saturation attack, and the shipyard should think of a way, and it will be lengthened to 210 meters if it is not 220 meters, which is very, very important." Li Kongrong emphasized, looking at Ma Deji's gaze extremely seriously.

"Bo Liang, let's find a way to lengthen it." Lin Xianxin also interjected. "I think the latest launch of the Japanese Canglong is also extremely long, since Hansheng said that the longer the better, then we will find a way to change it to be longer."

"I should do my best to do this, but I am worried about the ...... of this construction period" Ma Deji did not know how and where to build this aircraft carrier at this time, but these things will be discussed below.

"The construction period will start next year, the first aircraft carrier will be docked at the end of this year and early next year, and the second will depend on luck, but the docking time will not be later than September next year, and the third will be docked in July of the following year, at this time it is best that the first aircraft carrier has been launched and outfitted, so that the first dock can be vacated, and the fourth ship will be docked when the second ship is launched, which should be in early 1941." Li Kongrong roughly said it, and after speaking, he felt that there were still too few docks, so he said: "Let's talk about the dock later." Now the main thing is to discuss what aircraft carrier to build.

In addition to what I just said, there is also a catapult, the aircraft carrier must be equipped with a catapult, although it is okay to take off directly, but there will be more aircraft released by each wave of catapult, so the aircraft carrier must be equipped with a hydraulic catapult. The weight of the aircraft can be expected, and the weight of our carrier-based aircraft will be around five tons. By the way, there is also the height of the hangar, the shortest cannot be less than 4.6 meters, and the aircraft will not be able to fold the wings if it is shorter. In addition, the maximum length of the aircraft after folding the wings will not exceed 6.5 meters, and the fighter will not exceed 5 meters, and the width of the elevator should reach 14 meters, the length will be about 13 meters, and the maximum load will exceed 12 tons.

Because of the lack of cruiser destroyers in the early stage, the ship's anti-aircraft firepower can only be specially strengthened, not to mention the rest, which 20mm cannon authorized by France should be equipped with fifty or sixty guns, the key is to prevent low-altitude assault torpedo planes, as for the dive bombers above, you can ignore it first, so that the flight deck can be made wider, there is no angle of fire, there is no angle of fire, the Japanese bombs not only have problems with the fuse, the maximum is 25 bombs, we don't have to worry too much about this kind of bomb. ”

After saying so much in one go, Li Kongrong thought about it and said, "That's all I can think of, does Brother Boliang have anything to ask?" ”

"Not yet." Ma Deji finally took out a pen and began to record, he was very vague about what the aircraft carrier was going to become, but now Li Kongrong said all aspects in such detail, he was completely clear in his heart, but there was another question Li Kongrong didn't say, he asked: "Is the bridge placed on the left or the right?" ”

"On the right, of course." Li Kongrong smiled, and he remembered that there are now bridges on the left and right sides of the aircraft carrier.

"If the lift is on the outboard, the chimney can only be placed next to the bridge." Ma Deji said again, "In this way, the flight deck will not be equipped with armor?" ”

"Flight deck ......" Li Kongrong also thought about it, but thinking that the enemy was Japanese, he nodded and said: "The key to everything is to prevent torpedoes and fire prevention, these two points are done well, and we are likely not to sink a single ship in the next big battle." ”

"Can you really do it without sinking a ship?" Lin Xianxin looked at Li Kongrong, and after hearing what Li Kongrong said so much, he became more and more relieved.

"If you're lucky, you'll do." Li Kongrong replied very seriously. "As long as the Japanese prevent the torpedoes and control the fire, they will not be able to sink, but for the United States, on the contrary, they dive into the bombs and the torpedoes are a mess."

Unconsciously Li Kongrong brought in the evaluation of later generations, and he hurriedly changed the topic: "Shipbuilding is very important, since there are several aircraft carriers, let's buy shipyards in the United States." Now there is no war in Europe, and most of the shipyards related to the US Navy are open to the imagination, and other shipyards have no business at all. ”

"Buying a shipyard?" Li Kongrong successfully diverted everyone's attention, and Lin Xianxi asked: "How much does this cost?" ”

"We have to buy more than one, we have to buy a shipyard all the time, buy it and then go to the bank to mortgage it, and then use the loan to buy it, and finally we have no money to buy it and start the merger, in short, we have to build a shipbuilding group, and it is best to buy a steel plant, the bigger the better. Now New York is already looking for a suitable acquisition target. ”

After Li Kongrong explained, Lin Xianxi still didn't understand, so he had to say in a little more detail, "Europe is about to go to war, since there is a war, the German Navy will once again practice unrestricted submarine warfare, Britain will be more and more short of ships, we must be prepared to buy shipyards at a low tide, and then wait for Europe to go public and issue stocks after the war, and get the money from the stock market to build merchant ships or aircraft carriers." In addition to designing an aircraft carrier, the shipyard also had to design a 10,000-ton steamship using a steam engine, which should be simple in structure and easy to manufacture, and it was best to launch one ship a month. ”

"Launching one ship in a month?" Ma Deji was dumbfounded, and Lin Xianxin and Chen Wenlin couldn't believe it.

"If it can be done, it can be done by using welding instead of riveting, and then it is to simplify the shipbuilding pipe, and when the time comes, it will not take a month to build a ship." Li Kongrong said. "Going public is a sum of money, and the order we get from the British is another amount of money, in short, we want to build a large shipbuilding group. These new Chinese defense are already following suit, and all shipbuilding has to do is design a 10,000-ton dwt ship that is easy to build, and then evaluate the actual value of the shipyard to be acquired. ”

Seeing that the matter of building merchant ships was handed over to Xinzhong Defense, Lin Xianxi and Ma Deji were relieved, neither of them knew how to operate, and it was best to have professionals come forward.

"Is the dockyard big enough to buy the shipyard?" Ma Deji suddenly thought of the size of the dock.

"If it is not big enough, we will expand it, and the third and fourth aircraft carriers will be more than 250 meters long, more than 30 meters wide, and the displacement tonnage will reach 30,000 tons." Li Kongrong introduced the last two aircraft carriers, which once again stunned Ma Deji.

"There are such large mail ships in Japan?" Ma Deji asked in surprise.

"When the time comes, we will have it." Li Kongrong didn't say the reason, and smiled lightly at the corner of his mouth, "After the acquisition of the shipyard, in order to build the dock faster, let's not be so particular, just use the mud dock, which is the fastest." ”

"In the case, the mud dock will also do." Ma Deji nodded. "That is, can someone from the shipyard come to the United States?"

"Ordinary mechanics should not come, since they are in the United States, then use Americans, and designers and others can be transferred from China." Li Kongrong said.

"But there are dozens of people here." Ma Deji is fully aware of the Chinese Exclusion Act in the United States, and both he and Chen Wenlin are worried about it.

"Shipyards can let them in through business visas, isn't this equivalent to the Navy buying ships in the United States, didn't we send a lot of people here when we were building submarines in the United States twenty years ago? The aviation school has passed through the aircraft company, and it is not a problem for the instructors to come over, but it is difficult for hundreds of pilots to come in, not to mention that there are more than a few hundred pilots. There is also some trouble for the crew to come in after the aircraft carrier is launched, and Shuchun wants to borrow the Brazilian naval base as a training base, which can be regarded as a backup plan.

The solution on the side of the United States is to think slowly. For example, this time, when I was in Washington, there was a U.S. Army colonel named Chaffee, who was the commander of the 7th Armored Brigade of the U.S. Army, and he came to me to discuss armored tactics. In the future, the Americans will definitely expand their armored forces, and when the time comes to invite the army, the navy may be able to add some of them. Switzerland also has a lot of things that the US Navy is looking at, and we can use this as a bargaining chip to see if the crew of the aircraft carrier can come over at their invitation, which will take time, and we must take our time.
