Since the start of the naval holiday, the Chinese Navy has not launched a large ship for several years, and has been modifying and modifying the original ships.
The battleship Fuhao and several other warships were regarded as technology verification ships.
Once there is a new subsystem, install it and try it out.
Ellie has been disemboweled several times in the past few years, and the power system alone has been replaced twice.
Anyway, it’s just two words.
Anyway, once the navy and shipyards have a creative product, they will test it on it.
Because of the mature designs and ready-made data of later generations, China does not have theoretical and design bottlenecks in the technology tree of gas turbines.
It is only limited by materials and control systems.
In the past few years, China's basic research has laid a solid foundation.
The level of computers and materials has been advancing by leaps and bounds.
Therefore, gas turbine technology has also developed by leaps and bounds.
It was precisely because of these considerations that although the previous gas turbines were already practical, Wen Desi did not allow them to be applied on a large scale, but allowed them to continue research.
It was not until the fourth large-scale technology upgrade, namely the rc04 series gas turbine, that its performance, price, service life and other data were accepted by Wen Desi.
If compared with similar products from the original space and time, the performance of this series of gas turbines is already equivalent to the level of the late 1980s, and some projects have even reached the level of the 1990s.
After many transformations, the appearance of the "Fuhao Hao" is completely different from the original one.
It can be said that even the Italians themselves cannot recognize it.
When it was still called the Andrea Doria, it had five main turrets.
Turrets No. 1, 3, and 5 were triple-mounted, and turrets No. 2 and 4 were twin-mounted.
Now its main gun has been completely changed.
First, the turret in the middle of the hull was removed.
The turrets were reduced to four, and all were changed to twin mounts.
Then the main gun was also replaced with a 390 mm 50-caliber naval gun, and the Sun Wu-class The main gun is the same.
Naturally, all other weapons have been modified, all torpedo tubes have been cancelled, and all the original gallery-type secondary guns have been changed to turret-type.
The current secondary armament of the "Fuhao" is 16 130 mm 45 times caliber high and flat dual-purpose guns with eight twin turrets.
The latest model has 12 90 mm 50 times caliber high and flat dual purpose guns with six twin turrets, 42 40mm anti-aircraft guns and 26 20mm anti-aircraft guns.
The biggest change in appearance is to lengthen the hull by more than ten meters, add anti-torpedo protrusions, reshape the ship, and change the four main battery turrets from piggy-back to the same height.
Moreover, the entire original bridge was removed and completely rearranged.
The new bridge is completely different from the original one.
The armor has also been completely changed.
The main armor belt has been replaced with the latest composite armor plate similar to the Veneto-class armor.
The total armor thickness has also increased from 248 mm to 340 mm.
In addition, the underwater mine protection structure and cabins have also been significantly modified and optimized, and the entire hull structure has also been strengthened.
It can be said that Ellie has been completely reborn and transformed into a new battleship.
After being modified in this way, its displacement increased from the original 34,000 tons to nearly 40,000 tons.
In fact, China also spent a lot of money on this brand-new Aili.
Its modification costs are staggeringly high.
The combined cost of these major modifications has exceeded the construction cost of a Yue Fei battleship.
No way, technical verification is so expensive.
China is doing this now because, on the one hand, it is not short of money.
On the other hand, of course, it is due to the restrictions on Navy holidays.
If new ships are really built, they will occupy the remaining tonnage.
China's current capital ship tonnage share is only 80,000 tons, and Wen Desi obviously does not want to be in such a hurry to build new ships.
Anyway, there is no war now, so there is no need to worry.
It would be better to take advantage of this opportunity to conduct technical verification in all aspects of those newly invented subsystems and new design ideas.
Once needed, these new ones can be officially built.

In fact, it is not just China that is doing this now.
Several other great powers such as the United States and Germany are also doing this.
Even the most impatient Britain has now slowed down its speed of construction and begun to use some old warships to carry out magic operations.
Modify and verify their various new technologies.
"Reporting to the leader, each ship is ready to start experiments at any time," the commander of this experiment reported to Li Ang.
Li Ang nodded: "Okay, I understand.
Then, Colonel Zhang, let's start now."
"Yes" Colonel Zhang immediately issued a series of orders to each ship.
"Whoosh!"
Accompanied by the friction sound from the flywheel catapult, two Water Reconnaissance 3 "Puffin" seaplanes were ejected from the Yongguo seaplane carrier.
They will undertake the observation mission of this experiment.
This "Ruiyun" water reconnaissance aircraft with an appearance close to the original time and space was finalized in 1917.
It came out almost at the same time as the "Water Reconnaissance 2" "".
They are currently China's latest water reconnaissance aircraft.
There is a strong competitive relationship between Water Scout 2 and Water Scout 3.
The former is the masterpiece of Xiangyin Aircraft Company Xiangfei, and the latter is the masterpiece of Bohai Aviation Equipment Company, whose factory is located in Longkou.
As the saying goes, peers are enemies, and Xiangfei and Bohang are no exception.
These two are also the two largest and most technologically advanced seaplane manufacturers in the world.
Water Scout 2 and Water Scout 3 are products of their competition.
However, these two aircraft have their own strengths.
Water Scout 2 is more flexible and has very strong combat capabilities.
Its fighter jets are even as good as some foreign professional fighter jets. , and the advantages of Water Scout 3 lie in speed, ceiling, and range.
The dazzled military found it difficult to choose, so they simply took both.
Water Scout 2, which is more suitable as an observation aircraft, is equipped on large ships such as battleships and cruisers as a calibration aircraft.
The Water Scout 3, which has a faster range and speed, is equipped on islands, seaplane carriers and various auxiliary ships as reconnaissance aircraft.
The "Fuhao" and several light ships that were tested together sailed out of the queue and began to accelerate.
"Now four units are in operation, and then two units will be started every three minutes."
Xu Wei introduced next to him.
The tester next to him stared at the radar screen and kept reporting Ellie's speed: "16 knots, 18 knots, 22 knots, 24 knots, 26 knots, 28 knots, 30 knots, which is already over 32 knots."
"The acceleration is indeed far better than that of a steam turbine."
Li Ang nodded repeatedly.
He was very familiar with ships with steam turbines, and the acceleration of steam turbines would never be that fast.
It only took less than seven minutes to accelerate from 15 knots to 30 knots.
If it were powered by a steam turbine, it would be simply unimaginable.
"Now there are only 6 units in operation."
Xu Wei said with a smile.
"It's incredible that six units can reach 32 knots," Li Ang said with eyes shining: "The combined volume of the system of six gas turbines is not as large as two steam turbines.
It seems that this gas turbine is the best ship power. ” Because steam turbines are equipped with a large number of boilers and pipes, they are bulky and require a lot of space.
Even if the steam turbines currently used in China are the most advanced all-fuel small water tube boilers, their size is completely incomparable with gas turbines.
Xu Wei said with a smile: "You are right.
The gas turbine is indeed a very good power.
It is not only small in size, but also has fast starting speed and acceleration.
But it also has shortcomings.
First of all, the fuel consumption at low speed is too high.
It is not as good as a steam turbine.

If it has the same power, its fuel consumption is at least twice that of a steam turbine.
It also has short service life and high maintenance requirements.”
"Haha, we in China are not short of fuel, so this is nothing.
As for other shortcomings, compared with its advantages, they are completely acceptable," Li Ang said disapprovingly.
Diesel trees are now planted in many places in China.
In areas that are not suitable for traditional agriculture and need to protect the ecology, such as the Yunnan-Guizhou Plateau, Loess Plateau, and Nanyang tropical rainforests, diesel trees and other economic trees are the main species.
Provide hundreds of millions of tons of fuel.
And this output is still increasing.
Since there is sufficient fuel, it can naturally be wealthy.
The "Fu Hao" continued to accelerate, and ten minutes later its speed reached 37 knots.
At this time, its bow position was shrouded in water mist.
Fortunately, its bow was a wave-splitting type.
Shape, otherwise the sea water at this time can wash the deck.
And it's still accelerating "383940, God, 40 knots has exceeded 40 knots."
The officers and soldiers guarding the radar exclaimed in disbelief.
The "Fuhao" finally accelerated.
The 12 rc0428 gas turbines were fully powered at this time, providing it with a surging power of 336 megawatts and about 450,000 horsepower.
At this time, the "Fuhao" was already racing wildly on the sea. .
The bow of the wave-splitting floating ship splits the sea surface, and its powerful force turns the nearby seawater into splashing waves. "40. 4 knots 40. 4 knots."
The radar officer's face turned red with excitement.
At this time, the "Fuhao" has entered a state of full speed, and the waves on the bow of the ship have far exceeded the height of the deck.
When the speed reaches this level, even the effect of the wave-splitting type of floating bow begins to weaken. , there are already a lot of waves rushing onto the deck.
Li Ang was also very excited at first, but then he frowned and said, "It's too fast.
Xu Gong, look at the bumps and undulations of the ship's hull.
They are too big.
This will seriously affect the hit rate."
Although the weather is good now and the sea conditions are also It's low, but Ellie's speed is so fast that the bumps are like driving in strong winds and waves.
"It is true, so we need to test the hit rate and other performance of the ship at various speeds."
Xu Wei did not mince words and said very directly: "We need to use actual experiments to verify the optimal speed."
The speed of a warship is not as fast as possible.
Once the speed of a conventional ship reaches 32 knots, every increase in speed will cost a lot.
Although more gas turbines can be packed into a ship of the same size.
For example, after 12 units are packed into the current Ellie, the original power cabin is more than enough, but the price paid is too high.
You know, more than half of the cost of a battleship is spent on the power system, just like the Hood class and Nelson class in this plane.
The two started construction almost at the same time and have similar tonnage, but the cost of the former is twice that of the latter. , but the combat effectiveness was dragged down as far as eight streets.
According to the most conservative estimate, one Nelson can hang up and beat two Hoods.
It is really hanging up and beating.
So why is the Hood class so expensive?
The answer is speed.
The Hood has twice as many power systems as the Nelson.
Although the Chinese Navy is not short of money now, it is not willing to spend money on unnecessary places.
Even if the speed of the ship reaches 50 knots, or even 100 knots, so what?
No matter how fast the warship is, can it still be faster than an airplane?
This time, not only the battleship Ellie was tested, but also several other light ships equipped with gas turbines.
After more than a month of experiments, the verification team tested the performance of these ships from all aspects, including maximum speed, endurance, endurance at maximum speed, the status of the ships at various speeds, and weapon usage, etc., in total We have completed experiments on hundreds of projects and accumulated a large amount of first-hand information.

Xu Wei said at the summary meeting after the experiment.
"Taken together from these experimental data, I think it is more appropriate that the maximum speed of battleships, aircraft carriers and heavy cruisers should not exceed 34 knots.
It is appropriate that the speed of light cruisers and destroyers should not exceed 37 knots.
The speed of torpedo boats can be faster, so as to "Within 50 knots is appropriate."
This conclusion was reached jointly by the designers and users.
"It would be great if gas turbines could be installed on submarines," one officer said.
Xu Wei spread his hands and said: "Unfortunately, it is not possible yet.
Gas turbines have a large demand for air, and their exhaust gas temperatures are very high.
Surface ships can be installed with large ventilation devices, but submarines cannot be installed unless they float to the surface. , otherwise it will be difficult to use.
The diameter of the snorkel is too small to meet the working requirements of the gas turbine.
If the diameter of the snorkel is increased, the concealment of the submarine will be reduced, which is not worth the gain. " In the design institute, the idea of a gas turbine submarine has long been proposed, but unfortunately, after further calculations, they gave up this idea.
After the experiment was completed, Director Li Ang went back happily.
After he planned to go back, he applied to the superiors to modify the power system of the current main ship.
Anyway, there has been no need for major construction in recent years, and the dock is completely sufficient.
According to his vision, after this major change, all Chinese ships will be faster, and battlecruisers will be completely swept into the garbage heap of history.
By then, a large number of China's capital ships will have high speeds of more than 33 knots, and the picture will be too beautiful to even look at.
And those replaced steam turbines will not be wasted, even if they are no longer suitable for warships, they can be used on civilian ships without any problem.
Nowadays, various shipyards in China are developing commercial ships, and power systems are in short supply
