Gao Hongsheng smiled helplessly, stood up and walked to the edge of the table, glanced at the three views on the table and said, "Oh! Okay, okay, I'll help you see, now that the research on new technologies has just begun, Popper, can't you wait? ”

"Mr. Gao, the design of the new warship has taken into account the development of technology, and there is room for upgrading in all aspects, science and technology are always improving, and we are always unable to catch up. You can't wait forever. Popper said with some frustration.

This is an endless cycle, and the development of shipbuilding technology in that era can be described as changing with each passing day.

Here I will talk to you about the development history of armor steel, and you can see the development speed of shipbuilding technology at that time through the development of armor steel for battleships.

In the late nineteenth century, the armor plate of the battleship underwent iron armor, steel armor, rigid iron armor, nickel steel, Harvey hardened armor, nickel-chromium steel armor, and later Krupp carburizing hardened armor, which was actually the technology of surface treatment on the basis of nickel-chromium steel armor.

The steel-faced iron armor was first made by the British, that is, a layer of steel armor and several layers of iron armor were heated and stacked together to form a whole after heating, so that the steel-faced iron armor was formed, and the surface hardness was improved and the toughness was not reduced (Dingyuan and Zhenyuan are steel-faced iron armor), of course, the price was much cheaper than steel armor, and it was not brittle.

In 1855, the armor material used by ships was wrought iron, in 1876 France used Schneider "steel armor", in 1877 the British began to use steel surface iron armor, in 1888 Britain and France began to use nickel alloy steel armor, in 1892 the United States used nickel alloy steel for surface carburizing and hardening technology to produce Harvey steel, and in 1895 Germany Krupp made nickel-chromium alloy steel surface carburizing and hardening Krupp steel.

Science and technology are advancing, and the result of progress is that backward things will inevitably be eliminated.

France is engaged in nickel steel, and then the Americans engaged in nickel steel surface hardening, after the emergence of Harvey hardened armor, British steel armor and steel surface iron armor were eliminated, and nickel steel became the armor material of the deck, and to the German nickel-chromium alloy steel and its hardened version appeared, Harvey steel and nickel steel can only become obsolete products, since then began the era of 50 years of nickel-chromium alloy steel domination of the world armor steel, the armor on modern tanks and armored vehicles is still nickel-chromium steel alloy steel products.

How is the bulletproof effect of different steels?

1895 German Krupp steel, carburized case-hardened nickel-chromium alloy steel (KC) 6 inches (152 mm) thick armor protection equivalent to 5 inches (5 mm) Harvey steel, equal to 5 inches (5 mm) composite armor, or 16 inches (406 mm) wrought iron armor.

Cruelly, in just 50 years, with the continuous advancement of steel smelting technology, batches of originally advanced warships have become victims of scientific and technological progress, especially from 1888 to 1895, the continuous triple jump of armored steel like the leap development, during which the great powers spent a lot of money to build all the warships have become obsolete.

Look at the development of marine armor steel technology in the late nineteenth century, as if it was similar to the speed of the development of modern electronic technology in our country.

Do you want to know how the Western powers felt when they built warships in that era?

Refer to our old computer fans in the 21st century in the 90s,Facing the mood of computer upgrades,If you still don't understand,You can also refer to the update speed of the TV。

286 used to be an ironclad ship, the computer is still a newborn, if you have money, you can buy one, and if you don't have money, just look at the excitement and coaxing, everyone looks at those men to put on a façade, but there is no computer at home to make people laugh at it, grit their teeth and buy, just like that, 286, 386 and 486 former dreadnought-class battleships, poor and rich people have bought.

Well! Yes, everyone has it in their hands, no matter how the performance is, anyway, if you have it in your hands, you don't have to go out to greet people and lose face.

It's not the same in the Pentium era.,The dreadnought level is out.,This must be there.,Compared with those x86, it's too much exceeding.,Can this be without! It's more cheating daddy, there are too many Pentium super x86, x86 can't be upgraded to Pentium, isn't this Nima a pit daddy? And it's also software and hardware upgrades together, and it's not worth your life to die in a pit!

All right! All right! We have built the previous dreadnought, this dreadnought, we gritted our teeth and tightened our belts to move one, of course, we must keep some eyes, we must leave room for upgrades, okay, all kinds of dreadnought-class warships that have reserved room for upgrades have come out.

But when the Pentium series began to exert force, everyone was stupid directly, Made, the update is so fast, why just run one, two, three, and four in a blink of an eye, and line up to come out, which is too pitiful.

You said that you spent 8,000 oceans when you bought Ben 1, and Ben 2 will also be 8,000 oceans in the next year, and Ben 3 will still be 58 oceans in the next year, but can Nima Ben 1 be compared with Ben 3 and Ben 4? You say how depressed you are, let alone upgrade, no matter how much you run one, you can't change to four, buy if you want to keep up with the trend, and continue to tighten your belt to build a machine.

But there is still behind the gallop! But in the back of the Pentium series, you can be a super dreadnought. It was before World War II. Of course, we who bought Pentium went straight to tears.

If you use two computer CPU companies to compare the battleship empire of that period: Intel you can see it as the British Empire, and the troublemaker AMD is Germany, and you will probably understand what the world of giant artillery warships was like before World War II.

Forget about the main problem, the most awesome battleship armor that came out in 1930 at that time.

What to say about the country of Italy! There is always such a miracle as a flash of inspiration. Well, well, in 1930 this guy had another flash of inspiration in terms of the armor plates of the battleship.

Modular composite structure armor with 70 mm homogeneous outer layer, 250 mm foamed cement in the middle, then 280 mm case-hardened armor, followed by a 150 mm wood plank liner and a 12 mm back plate, and finally two 36 mm and 24 mm nickel-chromium steel fragmentation layers inside.

Awesome, do you feel stupid, composite armor! Nima came out decades in advance.

This armor design was designed according to the characteristics of the cap-piercing shells of the naval guns at that time, the outer layer of 70 mm homogeneous armor first killed the cap of the incoming cap-piercing shells, the middle cement layer was responsible for providing enough distance for the cap to fall off, the high-strength main armor 280 mm surface hardened armor knocked off the shells that lost the armor-piercing ability of the cap, and the rear liner and anti-fragmentation layer were responsible for blocking possible armor chipping fragments and shell shrapnel of penetrating armor.

In 1930, the genius idea of the Italians directly advanced the composite armor to 1930, and the genius idea, I wonder why people at that time did not think of engaging in composite armor on tanks!

Well! It's not right, at that time, the cap-piercing shells had not been used by tank guns, and the tank guns used tungsten alloy armor-piercing shells at that time. Don't think that the cap-piercing bullet is a tall thing, that thing has been there for a long time, and it is just a miniaturization to be used by tanks, and the battleship will always be at the forefront of science and technology in terms of scientific and technological applications, because no weapon system can have such a large carrier. It's far away.,That's it.,Don't explain it, I don't seem to be sorry for the information I found.,It's also for the sake of paving the way for the future.,There are two or three chapters below that are the history of the development of heavy industry at that time.。
