Chapter 532: National defense construction cannot be built by purchasing!

Together with the head of the railway company, I took the ‘Fuxing’ EMU southward.

Carefully inspected each section of the railway, bridges, tunnels, and stations.

Red flags and red banners can be seen everywhere, with motivational slogans on the banners for rushing work.

There is also a countdown time!

By the way, repair the ‘shield machine’ so that the ‘shield machine’ can continue construction in good condition and will not break down due to wear and tear.

All the way south, except for a few bridges and tunnels that have not yet been opened, most places have been opened.

Several groups of ‘Fuxing’ EMUs have been tested in different sections, and they also transport goods and conduct personnel training.

After arriving at Pengcheng Station, Liu Tao did not continue southward to Xiangjiang, but went to Yangcheng Shipyard.

However, the 054-type frigate ‘Qujing’ warship is about to be officially commissioned.

After a series of work during this period, the ‘Qujing’ has completed the test work excellently and can be officially delivered to the navy.

Originally, it was expected to be officially commissioned before or after the Spring Festival.

But because the performance of the "Qujing" ship was so outstanding and the work was completed ahead of schedule, it was officially put into service ahead of schedule.

And the Type 039 conventional submarine "Yuanzheng 20" will also be officially put into service.

Compared with the service of the "Qujing", there is no doubt that the service of the Type 039 conventional submarine "Yuanzheng 20" is more important, which means that the Chinese Navy submarine force will soon have advanced conventional submarines.

The Chinese Navy submarine force is not far from the day when it can enter and exit the first island chain at will.

Because the water depth in my country's eastern waters is not deep enough for submarines to hide, the East China Sea Fleet submarine force needs to enter the deeper waters to the east to obtain a better concealed combat space.

After all, the East China Sea continental shelf waters with an average depth of only tens of meters within a range of 500 to 600 kilometers are simply pitfalls.

However, China's current conventional submarines have an underwater cruising range of only two to three hundred nautical miles, three to four hundred nautical miles, which means that when the submarine sets out and maintains an underwater submerged state, it has not yet left the East China Sea continental shelf waters when it reaches the limit of underwater cruising range. It is simply too easy to be discovered.

The US military and Japan have very strong anti-submarine capabilities, and they don't know how many sonars they have deployed.

Besides, the underwater endurance of existing conventional submarines is two to three hundred nautical miles, three to four hundred nautical miles, which is just a theory. In actual use, they usually need to surface to charge when the remaining power is about half.

Therefore, submarine forces have always been tracked by anti-submarine aircraft of island countries when they leave the island chain.

The same situation also occurs in the submarine forces of the South China Sea Fleet. Although they can sail for a long time under the air cover of the naval aviation, they are basically out of the air cover range of the naval aviation after passing the Dongsha Islands.

And there are also many anti-submarine patrol aircraft there, both American and Soviet. This makes it easy for submarine forces to be discovered and tracked by anti-submarine aircraft when they leave the island chain.

The Type 039 conventional submarine is different. It has a stronger underwater endurance, a smaller sound, and is more concealed and difficult to detect.

Fixed-wing anti-submarine patrol aircraft mainly rely on surface search equipment such as airborne radar and forward-looking infrared search sensors to improve their submarine search efficiency and search range. This results in a significant decrease in the efficiency of fixed-wing anti-submarine patrol aircraft when searching for submarines that do not need to use snorkels for charging, which is equivalent to making fixed-wing anti-submarine patrol aircraft lose their radar search capabilities.

This also means that the Type 039 conventional submarine can easily break through the sea blockade and freely enter and exit the Pacific Ocean.

This is a killer at a critical moment, and can achieve effective strategic countermeasures.

When Liu Tao developed the Type 039 conventional submarine, in addition to the fact that the cost of this conventional submarine was much lower than that of a nuclear submarine, the navy could afford it with a bite of its teeth. Another important reason was that the Type 039 conventional submarine was very suitable for the current Chinese navy, which would greatly enhance the combat effectiveness of the submarine force and better deter jackals and tigers.

And now, the Type 039 conventional submarine is finally going to serve.

Several leaders came in person this time, not for the official service of the "Qujing", but for the service of the Type 039 conventional submarine.

"How long will it take for the Type 039 conventional submarine 'Expedition 20' to form combat effectiveness after it is put into service?" The old man asked, looking at the Type 039 conventional submarine.

The commissioning of a warship does not mean that it has combat effectiveness.

There are two dominant factors that take time to form combat effectiveness. One is the equipment factor of the ship itself. Because naval ships are different from other arms, naval equipment is complex and has a lot of technical content. It is not enough for only one or a few equipment to play a role. It requires that all equipment can be coordinated and meet the technical requirements of ship design.

If it is new equipment, it will take a little longer to form combat effectiveness, one year or even several years.

Because after the new equipment is installed, it must go through multiple debugging, and the weapon system must undergo live-fire demonstration to examine its stability and reliability.

The second factor that affects the formation of combat effectiveness is the humanistic factor, which is the quality of officers and soldiers. For a ship to form combat effectiveness, the captain and other officers and soldiers must pass the full training assessment, that is, full-subject training. Even if the ship's equipment is good, if the quality of officers and soldiers is not good, it is useless and combat effectiveness is still not formed.

Like these new equipment, they are composed of college students who graduated from naval military academies, in order to master the equipment faster and better, and form combat effectiveness faster and better.

But that's the case. The first Type 054 frigate, the Hong Kong Island, has just begun to form combat effectiveness, and the first Type 052 destroyer, the Xiangjiang, has just been commissioned. It is impossible to form combat effectiveness. It will take at least one year, or even two or three years to form combat effectiveness.

The more advanced the equipment, the more complex it is, and the more time it takes to form combat effectiveness.

Liu Tao pondered for a moment and said, "It will probably take a year, at least half a year!"

"The army is building faster, and the air force is also building faster with the introduction of advanced American fighters. Now the navy is left. We can't buy navy warships, and no one will sell them to us, not even the Americans. We have to build them." The old man said in a deep voice, "It's the fighter planes. Recently, the Americans have raised the price sharply. They want 44 million US dollars for an F-14 'Panda' fighter, and they say we are friendly and close friends. Now it seems that we must also develop our own air force equipment, so there will be no secret doors left, and we don't have to spend so much money."

Before China purchased F-14 'Panda' fighters, the price was 19 million US dollars per plane, the price of F-15 was 12 million US dollars, and the price of F-16 was 9 million US dollars.

Even at such prices, China was already heartbroken and gnashing its teeth.

Now, due to the depreciation of the US dollar and the war, the price of an F-14 ‘Panda’ fighter is 44 million US dollars, an F-15 fighter is 39.1 million US dollars, and an F-16 is 19 million to 20 million US dollars.

Such a high price, China simply can't afford it.

After all, military expenditure is limited. Now one US military aircraft is equivalent to two or three when China purchased it before.

This has also caused the voice of "it is better to rent than to make, and it is better to buy than to rent" in the air force equipment in recent years, and it has been crackled.

Facts have proved that weapons and equipment related to national defense construction cannot be bought by buying, and must rely on ourselves.
