As a battleship, Yamato is very excellent in overall design. It is the strongest battleship actually built in history and has the strongest naval guns actually installed.

Her hull design is also very excellent, using relatively reasonable early ball noses and has a very excellent cyclonic radius.

Using a power system of 150,000 horsepower, the hull of 70,000 tons was driven, and a relatively high speed of 27 knots was obtained.

She can be said to be a culmination of Japanese warship designs and is a very excellent and stable maritime shelling platform.

Of course, her shortcomings are also very obvious. The main reason is that the design concept can be quickly improved through learning, but the production process level can only rely on long-term accumulation.

As a late-developed industrial country, the Japanese industrial foundation has very obvious flaws compared to Europe and the United States.

It was only after the 20th century that the Japanese system had the ability to build large capital ships on its own in the era of the Russo-Japanese War.

Among the equipment of large battleships, the most dependent on industrial foundation is the power system of large ships, including boilers, turbines, transmission shafts, and gear sets.

Before the US was in the North Carolina class, it could not handle high-power transmission shafts and gear sets, so it had to use electric transmission for a long time.

The boilers and turbines of Japanese warships during the World War II era have always been relatively weak links.

Although the power system of Shoha and Shimafeng has good performance, its stability is not very good, which is a bit similar to overclocking products.

Yamato's final construction plan was a relatively conservative plan, and this conservative tendency ran through all aspects of the plan, including very important power systems.

Yamato boiler has a steam temperature of 325 degrees and a steam pressure of 25 kg per square centimeter.

Among the Japanese ships, only Canglong who was trying to mass produce was lower than her, and Yang Yan in the boat was higher than her.

The steam temperature of Xianghe's boiler is 360 degrees (Yangyan 350), and the steam pressure is 30 kg per square centimeter.

The highest level of Japanese boilers is island wind, with a steam temperature of 400 degrees and a steam pressure of 40 kg per square centimeter.

For comparison, American Fletcher has a steam temperature of 454 degrees and a steam pressure of 43 kg per square mile.

The island wind built a ship, but because the cost could not be controlled, it did not put into mass production, just like a handmade luxury goods.

However, Fletcher produced a mass production of up to 175 ships, and there were 70 Fletcher's improved versions of the Allen Sumner class and 105 Keeling class.

In the Japanese fleet, warships of different sizes and warships of different sizes may have different power systems of different standards.

American products are basically mass-produced, and most of the technical indicators are at an approximate level, from destroyers to battleships.

The system is imperfect, the standards are not standardized, and the product quality is unstable. It is also a typical feature of Japanese systems. This is a typical feature of incomplete industrialization and incomplete enough.

Although our modern products, although standardized and industrialized, have far exceeded the original Japanese products, and have basically achieved standardization and standardization.

However, the main gap between us and Europe and the United States is similar to that between Yamato and Europe and the United States at that time.

The most obvious gap between us and Europe and the United States is also in the categories of power systems that rely on accumulation.

Since the Second World War, the American Group has relied on its strong industrial foundation and has always followed the route of powerful bricks flying and powerful miracles.

The steam temperature of the Kitty Hawk level has been increased to 510 degrees and the steam pressure has been increased to 84 kg per square centimeter, which has been twice the island wind.

The purpose of the American system to pursue such extreme parameters is to use the steam of the power boiler to directly power the steam catapult, without burning special boilers.

After achieving this goal, the corresponding parameters have never been improved, just like the steam turbines used by Nimitz and Ford have always been maintained at the Kitty Hawk level.

Because this is enough, I don’t have to upgrade my face for sixty years...

Many industrial technical indicators have not been upgraded for many years after reaching their peak in the Cold War era.

The technical routes of the Chinese and Soviet systems in boiler systems are similar to those of the World War II era.

Due to the obvious gap between technical accumulation and the United States and Britain, we can only achieve the same effect of the American system through optimized design in other directions at a lower temperature.

The products obtained in this way will be significantly lower than those in the American system if they simply look at the basic parameters.

For example, the boiler of the Type 956 destroyer has a steam temperature of about 470 degrees and a steam pressure of about 64 kg per square centimeter.

In the design of the 1143.8 (Uriyangnovsk) aircraft carrier, a special separate steam boiler is also used to provide steam for the catapult.

Because the steam pressure provided by Ulyanovsk's reactor directly does not meet the requirements of the catapult.

The advantage of this design is that you don’t have to worry about the problem of insufficient air mobility when the catapult continues to work.

But it makes the hull structure complicated, which runs contrary to the concept of weapon design's pursuit of simplicity.

When designing the aircraft carrier of the China Series, it actually faces the same problem. As a result, because electromagnetic catapults come from behind, this problem will no longer be considered on the earth.

Xu Xingchen did not get an electromagnetic catapult in the early days. When he shot a steam catapult, he switched to Yuanwang to solve this problem.

At that time, based on the 051B Shenzhen power system, using the technology of Shiniang World, we developed boilers and turbines with technical parameters that meet the standards.

In fact, it is an upgraded and optimized product for the same boiler and turbine system as Liaoning and Shandong.

Two 454C supercharged boilers provide steam and a 453C steam turbine, providing 50,000 horsepower.

The four boilers and two turbines set provide 100,000 horsepower, which can be used as the main engine of destroyers and cruisers.

The set of eight boilers and four turbines provides 200,000 horsepower and can be used as the main engine of aircraft carriers and battleships.

The steam temperature is 580 degrees, and the steam pressure is 88 kg per square centimeter.

Just looking at these basic technical indicators, they have exceeded the boiler level passed down by the Eagle's ancestors.

The higher the basic technical parameters, the greater the power provided per unit weight, and the lower the total weight of the power system required to provide the same power.

Xu Xingchen replaced Yamato with this modern power system, which increased Yamato's total power from 150,000 horsepower to 200,000 horsepower and speed to more than 30 knots. The hull weight was reduced by almost half, saving a lot of space in the hull core cabin.

Then Xu Xingchen dismantled the useless triple 155 secondary gun, so that the space saved by the secondary gun group and power system can be concentrated in the rear of the bridge, and a main turret can be added to increase the number of Yamato's main guns to 12 460 mm.

On this basis, Xu Xingchen equipped her main gun with an automatic fire control radar system and installed a mature sea-to-air search radar.

Although she did not give her an over-visual radar, the Yamato's bridge was tall, and the observation distance of conventional radars to combat ships could reach more than 40 kilometers.

With the cooperation of the fire control radar, the combat distance of her main gun can be truly increased to more than 30 kilometers, and it can "twist" like in naval battle games.

Next, on the Yamato deck, 16 sets of AK130 double 130 mm guns are arranged as outer ring anti-aircraft guns and secondary guns, 16 sets of AK726G double 76mm naval guns are used as middle ring anti-aircraft guns, and 24 sets of 76A double 37 mm naval guns are used as inner ring anti-aircraft guns.

Such an anti-aircraft gun system may not be very effective against modern jet aircraft and anti-ship missiles, but it can rest assured to deal with propellers.

After completing the main weapon system, Xu Xingchen directly dismantled the seaplane ejection and recovery system of the Yamato ship's stern and replaced it with a helicopter take-off and landing platform.

In order not to affect the main gun, the helicopter hangar is set inside the hull below the platform, and an inboard lift similar to amphibious attack is set at the tail of the ship.

Yamato's hull is large enough that the space inside is very spacious without personnel required. If the stern of the ship is slightly cleaned up and 8 helicopters can be placed.

The helicopter Xu Xingchen could not give her a complete body 20, but instead removed the streamlined version of 8 of various modern equipment. After all, she is still an outsider now.

Other ship-based equipment such as observation radar, main gun, secondary gun, anti-aircraft gun fire control radar systems, etc. are all early products with simple functions produced by modern mature technologies.

Their combat effectiveness is of course far greater than similar products from World War II, and it is more convenient and simple to operate, but it does not widen the essential gap.

Yamato, which was transformed in this way, still looks like a traditional battleship, but it is just a traditional battleship that has reached its peak.

After the basic plan was completed, Xu Xingchen examined the current transformation plan as a whole and slightly adjusted the deconstruction of the cabin inside the hull.

There is no adjustment to the special cabin similar to that of the ship girl in Hunan, but it only uses the existing space to slightly enhance the basic defense capabilities.
