Lin Yuan continued: "Which is more suitable for the weapon of the warship or the artillery shell, I believe everyone will choose the missile, in our time, the warship is armed with missiles, the reason is very simple, the missile is equipped with a seeker, it hits accurately, and it has its own power plant, and the charge can be very large, for example, the Russian SS-N-12 missile, the warhead is loaded with high-energy explosives weighing up to 900 kg." ”

"900 kilograms, nearly a ton of weight, other missiles also have a charge of more than 100 to 500 kilograms, and the largest caliber artillery in the history of human naval warfare, the 460 mm main gun of the Yamato-class battleship, uses a shell with a charge of only more than 300 kilograms, so the power of the missile is stronger."

"So many explosives, one shot can inflict a devastating blow on the enemy's warship, and in our time, in the 1982 war between Britain and Argentina over the Malvinas Islands, Argentina used Exocet missiles with a charge of 165 kilograms, sinking the destroyer Sheffield with a full load displacement of more than four thousand tons."

Lin Yuan said: "Since the enemy has embarked on the road of large ships and huge guns, their industrial system will develop in that direction, and it is not easy to change, so their warships will become bigger and bigger, in our time, in order to carry larger guns, the tonnage of battleships has risen sharply, and the full load displacement of Japan's Yamato-class battleships has exceeded 70,000 tons; In 1922, the European powers, the United States, and Japan signed a treaty on the limitation of naval armaments, and with this treaty, the momentum of frenzied construction of giant ships was curbed. ”

"And in our time, this treaty will definitely not appear, so they will build warships bigger and bigger, and if we still use artillery shells, it will definitely not work, so we will put missiles on ships, and now I invite Academician Gao Ninghai, a missile expert, to introduce us to the latest progress of missiles."

Gao Ninghai smiled embarrassedly and said, "I'm ashamed to say that if we want to talk about missiles, I'm afraid we won't be able to reach what Comrade Xiaolin said." ”

Lin Yuan asked, "Then what are the technical difficulties now?" ”

Gao Ninghai said: "There are two main difficulties, one is power, the other is control, let's talk about power first, there are two main types of missile power, one is to use a rocket engine, the other is to use an aircraft engine, if it is a rocket engine, the manufacturing process of the propellant is not up to standard, and it is still difficult to create a qualified propellant, if it is an aircraft engine, the missile body is very small, and we cannot make such a small engine for the time being." ”

"And then there's control, and now that our electronics industry is just getting started, it's going to take some time to build a reliable guidance system."

Lin Yuan nodded, thinking, "Since the missile can't be built, it's okay to let the shells hit more accurately." So he turned his head to look at the laser expert Qin Peng and asked, "Old Qin, how is our semiconductor laser development now?" ”

Qin Peng saw Lin Yuan and Gao Ninghai talking about missiles, and felt that there was nothing wrong with him, and he was suddenly a little surprised by Lin Yuan's question, Qin Peng was stunned for a moment before saying, "It's going well, what's wrong?" Do you want to use the laser as a weapon? Diode lasers don't have that much power. ”

Lin Yuan shook his head and smiled: "What I want to say is a laser proximity fuse, I think so, our artillery accuracy must be very high, in this way, we install a laser proximity fuse on the shell, this kind of shell can fall on the enemy's warship like an eye, this can be seen as a substitute for missiles, we will first make a batch of such shells, and then replace them after the missiles are produced." ”

Everyone nodded, and Lin Yuan continued: "Now I will talk about the last part, the fire control part, this part includes searching for targets, target ranging, etc., when I was in Germany, I saw the stereo rangefinder, and I also saw the gyroscope, and when I visited the fire strike demonstration of the dreadnought, I found that their guns were very accurate, so I concluded that they used a fire control system with a mechanical computer." ”

"They also use optical ranging, which is not a good way on the battlefield, because there will be a lot of smoke on the battlefield of naval battles, and sometimes there will be fog, so our fire control system must be based on radar, and I will ask radar expert Academician Ma Zhiliang to introduce the progress of the radar system to us."

Ma Zhiliang said: "Our radar system is also facing some problems, the most important problem is that the frequency of electromagnetic waves that our radar can emit is relatively low, and if the frequency of electromagnetic waves emitted is low, the error of the measurement angle will be relatively large, this kind of radar can only be used as a warning radar, not as a fire control radar, so the shells are not easy to shoot accurately, mainly because we have a lot of advanced components that have not yet been manufactured." ”

Lin Yuan asked, "What about measuring distance and speed?" ”

Ma Zhiliang said: "Although there is still a certain error, the error is certainly much smaller than that measured by foreigners optically. ”

Lin Yuan said: "Then let's install the radar first, and then change it later." ”

Everyone nodded, and Lin Yuan continued: "Hearing the speeches of the experts, I think everyone has a general understanding of the equipment of our warships, our warships will be equipped with gas turbines and radars, and now they will be equipped with artillery shells with laser proximity fuses, and they will be replaced with missiles in the future, as for the types of artillery shells?" I propose to use three kinds, one is a shell-piercing shell, didn't we get a lot of tungsten ore? It is used to make steel cores, and there is also an armor-piercing explosive bomb, and the last one is a cloudburst bomb. ”

Everyone said: "Such a battleship can definitely be regarded as the strongest battleship of this era!" ”

Lin Yuan smiled: "Now let's talk about how many warships should be built?" And how should our navy be formed? ”

Han Mingguang said: "You better tell us what you think." ”

Lin Yuan said: "Actually, I have been thinking about this problem for a long time, we now have an invincible aircraft carrier in the world, and in the future, the technology will be more mature, we will build more aircraft carriers and fighters, we should organize warships and aircraft carriers into battle groups, that is, aircraft carrier battle groups, in the battle group, the aircraft carrier uses its ultra-long-distance detection capability to detect the enemy's formation, and then we deploy our formation in a targeted manner." ”

"So I decided, we want to build a blue-water navy, this navy is composed of more than ten aircraft carrier battle groups, which can go to the enemy's doorstep to fight, do you think it's okay?"

Everyone nodded in agreement, and Lin Yuan continued: "We have formulated the naval strategy, and then let's talk about the issue of ship types, in this era, the core of the fleet is the battleship, the battleship has strong firepower and thick armor, and is the main force of the sea battle; The second is the cruiser, compared to the battleship, the firepower and protection of the cruiser are relatively weak, but the speed is fast, and it is used for long-distance reconnaissance when engaging at sea, and it can also undertake part of the combat mission. ”

"And then there are destroyers, destroyers are very fast, their firepower and protection are weaker, their main purpose is to repel the opponent's torpedo boats, and then there are frigates, in our time various countries are equipped with a large number of frigates, but the frigates of this era are still very weak."

Lin Yuan continued: "After talking about this era, let's talk about our era, and then select the type of ship of our fleet for everyone's reference, in our era, battleships have completely withdrawn from the stage of history, cruisers have become a thing of the past, destroyers and frigates are the mainstream of warship development." ”
