Three hundred and eighty eighth chapter warship modification
ps: Thank you to the book friend "Shengqi" for your evaluation vote, and continue to ask for recommendation votes^_^
However, these requirements of Hu Weidong cannot be said to be unreasonable. After all, the Omaha-class light cruiser is an old ship type with a lot of design styles from the First World War. There are many places in the design that are not suitable for World War II. Although Hu Weidong is not an expert in ship design
, but as a senior World War II warship enthusiast, he still knows the experiences and lessons summarized by later generations. As long as these opinions are put forward, experienced Americans will naturally know how to modify them.
Naturally, the United States will also benefit from this process. However, because of the contempt of technicians in the U.S. Navy and shipyards for their Chinese counterparts, few people can humbly learn the naval warfare concepts from China, a "backward country", let alone
A large part of those improvement suggestions are specifically aimed at China's national conditions and the military conditions of the Chinese Navy in the future. Americans can't learn from them even if they want to...
Although Hu Weidong, a time traveler, is very dissatisfied with the current Omaha-class light cruiser, for the Chinese Navy whose foundation is still very weak, the performance of this light cruiser is actually very good. Its basic parameters are as follows:
It can be seen from the above data that although the ship is relatively old, its firepower, armor, speed and endurance are quite good. However, in Hu Weidong's view, the design of this warship has many obvious flaws.
...
First of all, the air defense capability is weak. Although it is equipped with many large-caliber high-level and high-level dual-purpose guns, it is not equipped with small-caliber anti-aircraft guns or anti-aircraft machine guns. As a result, once enemy bombers close the distance during air defense operations, the ship will be completely destroyed.
Loss of resistance; secondly, there are too many 152mm caliber main guns, which is a waste for the Chinese Navy, which is rarely assigned to perform ground fire support tasks. Although 1
The 52mm naval gun is not incapable of air bombardment. However, the air defense efficiency is far behind that of the more professional 127mm high-level and flat dual-purpose gun. Hu Weidong would rather give up most of them to free up space and load on the ship, so that additional installations are indispensable.
There are few close-range anti-aircraft weapons; the maximum speed is slow, and it cannot outrun the Japanese heavy patrols. Once encountered, it will be hit and beaten again and again, and it is impossible to escape. How can it be called "miserable"; the battery life is too long.
If it is too large, it would be a bit of a waste for the Chinese Navy, which is unlikely to conduct ocean warfare for a long time. To Hu Weidong's surprise, Zhongfu International's improvement requirements in this regard actually made the US government lower its guard.
.The control over the sale of equipment and technology has been slightly relaxed, which is undoubtedly an unexpected surprise; in addition, for the future, the main focus is on "using aircraft to deal with enemy ships" and "warship-assisted air defense"
"For the Chinese Navy, the overly thick side armor of this type of light cruiser is undoubtedly very useless. On the one hand, it takes up too much load, and on the other hand, it is completely useless in air defense operations. It is difficult for aerial bombs to hit the warship.
(Theoretically, it can be thrown over by inertia, but it is too difficult to operate in actual combat.), and the powerful torpedo cannot stop it at all. Even the light aviation torpedo with the smallest charge is the same...
Although Hu Weidong is not a warship expert, his knowledge of artillery fire is unparalleled in the world. He also knows the development trend of warships in later generations. In addition, the Third Fleet already has many battle cases for reference. Therefore, many of his opinions as a layman are almost unparalleled.
They all hit the mark, which made the negotiators of the US Navy click their tongues.
Strange, so they readily accepted most of the requirements, with the hull being modified first. The main armor thickness of the side strings was reduced to 25mm (Note 1), and the armor of the deck and command tower was thickened to varying degrees. The two ships
The standard displacement of the cruiser has therefore been reduced, falling to less than 7,000 tons.
(Because a lot of close-range anti-aircraft guns were installed, it was actually more than 100 tons lighter.) In addition, the bow of the ship was changed to a bulbous bow that can increase the maximum speed (this technology will soon be widely used by the U.S. Navy,
Therefore, Hu Weidong no longer needs to hide and tuck it in.), allowing its maximum speed to reach 3
6 knots, and the endurance has dropped a lot, to 3000 nautical miles/18 knots (the bulbous bow used has been chosen to have the greatest effect on reducing wave-making resistance at the maximum speed, so the low-speed navigation performance is greatly affected.
As a result, the [economic] cruising speed has been greatly accelerated.)......
As for the firepower configuration on the ship that Hu Weidong is more concerned about, after some communication and negotiation between the two parties, although the U.S. Navy does not believe that China can build better artillery than the United States, it still wants to come to the border area based on the idea of customer first.
The weight, caliber, barrel length and other basic data of various types of artillery produced, and based on this, the ship was adjusted according to the requirements of Chinese buyers.
After more than three months of modification, only two 152mm main guns at the front and rear were retained, while the remaining eight gun positions were replaced with four single 127mm high-level dual-purpose guns and four twin-mounted 88mm anti-aircraft guns.
At the same time, eight 76mm secondary guns were replaced with twin 57mm anti-aircraft guns in accordance with China's requirements, greatly enhancing long-range air defense capabilities.
The reason why the 57mm anti-aircraft gun that had been abandoned by Hu Weidong was re-produced and equipped with troops was thanks to the advancement of radio proximity fuze technology. It started with the invention of the transistor, and it didn't take long for this new thing to be applied.
When it comes to proximity fuzes, the volume of radio proximity fuzes used in anti-aircraft artillery shells has been greatly reduced, so that they can be used for missiles with a caliber less than 75mm.
Anti-aircraft artillery shells, but considering that aircraft are much stronger than the human body, if the charge of anti-aircraft artillery shells is too small, the lethality and radius of the shrapnel will be seriously insufficient. In addition, there are problems with processing difficulty, so the caliber cannot be too small.
57mm is almost the limit, and this is thanks to the invention of the "rod warhead" and its wide application in proximity fuze anti-aircraft shells...
Note 1: The influence of traditional concepts is not so easy to reverse, and this thickness of armor can also prevent the two light cruisers from being bullied by Army field guns without armor-piercing ammunition. If a situation similar to the "Amethyst Incident" occurs in China
It’s not fun at all when it comes to the navy... (To be continued. If you like this work, you are welcome to come to Qidian () to vote for recommendations and monthly votes. Your support is my biggest motivation
