Eagle Sauce: The 055 destroyer was launched into the sea just after the founding of the country?

To build Dragon Country’s first aircraft carrier, the first thing to do is to expand the dock.

Different from ordinary warships.

The length of each dock for manufacturing aircraft carriers must be more than 300 meters.

Such a huge dock cannot be met even by the Dallion Shipyard that manufactures arsenal ships for the Dragon Kingdom.

So, after Fang Yu's careful consideration.

It was decided to directly demolish the small docks around the Great Wall Military Factory and expand them into large docks.

There are two benefits to doing this.

Firstly, placing the dock so close to the Great Wall Military Factory makes it more convenient to transport and test any new equipment.

Secondly.

Dalyan Shipyard is in a better location though.

But it is too far away from the Great Wall Military Factory.

Fang Yu had to travel hundreds of kilometers every time to arrive.

Unfortunately, building an aircraft carrier is not something that can be completed overnight. Even if it is done as quickly as possible, it will take two to three years.

I can't always run back and forth between the Dallion Shipyard and the Great Wall Military Factory.

What's more, Fang Yu's long-cherished wish has always been to build the Great Wall Military Factory into the number one military factory on Blue Star.

Since we are the number one on the blue planet, we can’t just research weapons for the army, we have to build equipment for the navy and air force as well.

This dock and wind tunnel will be built sooner or later.

In that case, why not take this opportunity to build it directly...

After making up his mind, Fang Yu immediately took action.

On a sunny day, groundbreaking ceremony was held for the construction of a large shipyard.

This time, Fang Yu not only equipped the dock of the Great Wall Military Factory with a 3000-ton gantry crane that was more advanced than the Dalian Shipyard.

They even directly manufactured a set of automated welding units, CNC cutting platforms, X-ray flaw detectors, laser tracking measurement systems and other equipment that even Western countries do not have today to ensure the accuracy of the aircraft carrier's segmented cutting and assembly...

Time flies like a white horse, never stopping for a moment.

With the cooperation of the Great Wall Military Factory's already very capable construction team and engineers from all over the country who came to assist Fang Yu.

Three months later, a huge and sci-fi dock was erected...

……

After laying a solid foundation, Fang Yu began to take the first step in building an aircraft carrier.

As the first step in everything, the first problem Fang Yu faced was the material problem of manufacturing the aircraft carrier.

In the era when I lived in, on some social platforms, when talking about the Dragon Country's aircraft carrier, as soon as you praised it, there would be many nitpickers who had only a superficial knowledge of weapons coming out to criticize you.

The general speeches are all the same, and most of the content is about looking at the Eagle Sauce/Sakura/John Country, which started using aircraft carriers during World War II, while the Dragon Country only has aircraft carriers now, and I don’t know how many generations behind them it is.

However, the reality is that, apart from being ships, aircraft carriers during World War II and modern aircraft carriers are almost two completely different things.

Among them, the most different point is the materials used to build the aircraft carrier.

During World War II, the Eagle Sauce did have quite a few aircraft carriers.

Even the Eagle Sauce only needs one or two months to build a light aircraft carrier.

However, this does not mean that the production capacity of the United States is so incredible.

Because many light aircraft carriers during World War II were even simpler to manufacture than some cargo ships.

After all, during World War II, the carrier-based aircraft commonly equipped by the armies of various countries were propeller fighters.

The maximum take-off load is only 6 tons.

Moreover, because the take-off and landing methods of these aircraft did not require turbofan/turbojet engines, the decks of aircraft carriers at that time did not need to be made of special materials.

However, the aircraft carrier that Fang Yu wants to design is different.

The standard of the aircraft carrier that Fang Yu wants to build is based on the third-generation aircraft carrier "Fu Jian" owned by Longguo after the millennium.

Carrier-based aircraft must also be replaced with third-generation fighters.

Therefore, its manufacturing difficulty is simply incomparable to those of the Eagle Sauce's aircraft carriers.

Among them, the most critical and difficult technical difficulty to overcome is the special steel used in aircraft carriers.

This kind of steel must have several critical characteristics.

First, it must be resistant to seawater corrosion.

Seawater is particularly corrosive to the bottom of ships, which will seriously affect the speed and protection capabilities of the ships.

Therefore, the steel used to build general civilian and military ships is required to have strong resistance to seawater corrosion.

Since the operating environment of an aircraft carrier is more severe and maintenance takes longer, the steel plates used are required to have a stronger ability to resist seawater corrosion.

Secondly, the steel must be anti-magnetic.

Generally, steel has a certain magnetic force.

Since the earth itself has a magnetic field, ships made of low-magnetic steel will be magnetized by the earth's magnetic field and generate magnetic force after long-term use.

Magnetic forces are very detrimental to warships.

Because this is easy to be detected by enemy magnetic detectors or attacked by enemy weapons such as magnetic mines.

Therefore, warships use steel with as little magnetic force as possible.

Third, this steel must have extremely strong resistance to high temperatures and impacts.

When an airplane takes off from land, it generally needs a runway of more than three kilometers, or at least one or two kilometers, to run up and take off.

On an aircraft carrier, an aircraft must complete the process of taxiing, taking off, and taking off from a stationary state within a distance of one or two hundred meters.

In addition to the catapult's propulsion, this also requires the aircraft itself to have strong thrust.

When the aircraft is powered up enough to take off, the flames ejected from the engine can reach thousands of degrees, enough to melt a deck made of ordinary steel!

Moreover, each carrier-based aircraft generally weighs about 30 tons, and when landing, the impact on the deck is extremely great.

Therefore, the requirements for the deck's impact resistance and torsional resistance are very high.

If the steel used for the deck is not up to standard, the landing aircraft is likely to lift up the flight deck through the arresting cables.

In addition, the aircraft carrier deck must have a strong ability to resist enemy armor-piercing projectiles.

Therefore, the steel used for aircraft carrier decks is extremely demanding.

The last point is that this aircraft carrier steel must have the characteristics of high toughness and high strength at the same time.

Due to the special nature of aircraft carriers, the strength required of the special steel used in their construction is much higher than the steel strength requirements of ordinary military ships.

The use of high-strength steel plates can reduce the weight of the hull and increase its bullet resistance.

In particular, the steel of the flight deck must be made with higher quality because it has to withstand the high heat and high friction during the takeoff of carrier-based aircraft.

Therefore, the hull of an aircraft carrier must be made of high-strength alloy steel.

The yield strength of special marine steel is generally expressed in MPa (megapascals).

For civilian ships such as oil tankers, bulk carriers, and container ships, steel with a hardness of about 250MPa is sufficient, while for ordinary military ships, steel with a hardness of less than 300MPa is sufficient.

The steel used in aircraft carriers and submarines, especially the steel used in aircraft carrier flight decks, is generally required to be above 850MPa.

Converted into units we are familiar with, an area of ​​roughly one centimeter must be able to withstand an impact force of 5000 to 8000 kilograms.

It's easy to imagine how big a challenge this is to Fang Yu's material manufacturing capabilities...
