In a certain sense, China has begun to directly threaten the US mainland, but in the eyes of the Americans, it is a warship, and the battleship will not be able to go ashore or even last if it causes losses in another battle, and as long as the Americans are careful, strengthen patrols, and blockade the port with mines, it is impossible for the attack on New York to happen again.

Although the four Fantasy-class ships caused panic on the entire east coast in the United States, and 40 million people fled, even if China can completely block this side and leave the sea at most 40 kilometers, it is difficult to do it, the battleships are 40 kilometers away, they can also threaten the United States, and the United States is safe without sufficient landing and delivery capabilities.

The distance between China and the United States makes it very difficult for both sides to attack each other, and any long-range projection, after more than 10,000 nautical miles, will become an impossible task.

But what if China has a key point between China and the United States? However, the distance between the occupation of Hawaii and even Guam and the United States is much closer, and the distance between Guam and the United States is already very close, although it is still very far away, but compared with the previous tens of thousands of nautical miles, it has reached an acceptable range.

The premise to solve this problem is that the Panama Canal cannot be completely blocked, and in this case, the United States will not be able to have the spirit to put its strength on the European side, and in the face of a strong challenge from China, whether they want to or not, they must compete with China in the Pacific Ocean, and the result of this confrontation is completely unpredictable.

I thought that I had already grasped the pulse of the Chinese, but I did not expect that the Chinese had grasped the strategic key in the most inadvertent place, and China had changed from a country without a navy to a country with a strong navy, no matter how much they underestimated China, in the face of the current results, they must also put China on the same or even higher degree, they will not think that China is only to retaliate against the United States, this is rushing to Panama, this must be with a strategic height, as long as Panama is cut off, At least in a year or so, the US warships will not be able to take care of the Pacific Ocean, and at that time, all the islands and strategic points under their control will probably be lost one by one.

Thinking of this, no matter how unwilling the Americans were, they had to speed up, and the two-pronged approach, radio immediately contacted the fleet, and sent the fastest communication ships, so that the fleet returning from Europe turned around, no longer returning to the United States, but rushing to the Caribbean.

Although the United States was very angry and sent a fleet to support Panama, at this moment, it could not have the slightest solution, because it could only rely on Panama's protection to survive this crisis, after all, that fleet was several days away from the United States, and it would take more time to turn to the Caribbean, and before that, the United States could not rely on much.

Generally speaking, Panama's protection is sufficient, this can withstand the attack of at least more than 10 capital ships, and even a group of torpedo boats, but now, what appears there is Cheng Biguang, who has been proven in New York, this murderous guy who even burned the whole Wall Street, is Panama's protection enough?

In fact, in fact, it is really not enough, it is too far away, after Panama sent a distress message, Panama's protection system was devastated, countless armor-piercing shells passed through a long distance, and finally fell on the gun position with great accuracy, powerful, enough to protect Panama's heavy artillery, one by one was overturned, in order to attack Panama, Cheng Biguang made a lot of preparations, including special shells to deal with land-based batteries. At this point, in fact, China has come to the forefront of the world, and when all countries are still thinking about how to use the strongest spear to break the strongest shield against the shells of the fleet, China has weakened the role of battleships.

That's right, the fantasy class is such a perfect battleship, in the future Chinese Navy, is an auxiliary ship, the battleship from the original capital ship, decisive battleship, gradually turned into auxiliary work, on the one hand, as the basic protection force of the entire battleship group, strengthened air defense and many other aspects, on the other hand, as a night barrier fleet, at night will become the capital ship for raids, blocking, covering a series of work, and even at a certain time, will become a fire support ship, for landing operations or other aspects of operations, good fire support, these are the important areas to play the battleship, so the capital ship is not only for the ship, but more diversified.

This kind of diversification has given tremendous pressure to the military industry and logistics field, and every time there is one more kind of artillery shell, it is necessary to develop an additional production line, specifically for the laboratory and follow-up experimental research of this artillery shell, so that the investment will be very large, but now China, in terms of scientific researchers, although there is a lack of top scientific researchers, but since 1908, the training of the lowest scientific researchers, the perfect education system, coupled with personal efforts, in the number of scientists at the bottom, there is no shortage of them. Although this kind of cultivation is tantamount to pulling out seedlings to help grow, it greatly supplements China's shortcomings in basic science and technology. With the existence of Yang Yuanzhao, at a considerable level, China does not lack the direction of the future guiding path, and even does not lack the top scientific research path.

As for the funds, China is not lacking, because of the sudden declaration of war between the United States and the Entente, China has lost a lot of funds, but since 1910, large-scale exports of various industrial products, China's industrial production has accounted for more than 40% of the whole world at its limit, and now, China is still supporting the Allies, and can harvest a large amount of money every year.

Four ships, even if they have broken through Wall Street, but the reinforced concrete city, although strong enough, but compared with the dam, this difference is big, the same reinforced concrete 1 meter thick and 5 meters thick, this is completely different, the lock, at least 50 meters thick, even from top to bottom, is a huge and complete part, that strength is probably terrible.

Countless shells, first destroyed Panama's ground defense, for the long-term peace of the U.S. military, has never suffered such a total, first of all, infantry anti-personnel shells, anti-personnel gun positions on the personnel, and then rely on strong attacks, fixed-point cleaning of artillery positions, Panama has a total of more than 170 12-inch guns, these were cleaned up like a roll call, the whole Panama became an undefended city. Panama is divided into two parts, relying on the core area of the Gatun Lake system, flanked by long locks, not only has a wave protection, but also a huge dam that is large enough to resist earthquakes of magnitude 8 or more, this dam is the focus of interception on both sides, as for the locks next to the dam, if damaged, the production capacity of the United States, can be completed quickly, and it cannot play the role of cutting off the Panama Canal.

The whole canal is divided into three parts, the anti-wave is located outside, easy to repair, but also the target of the strike, the blow is hit, if only the anti-wave is destroyed, for the Panama Canal, the impact is not too big, as long as a little repair, or even not repaired, the adventure can also be accompanied, only to break the dam, and even destroy a series of equipment near the dam, can he be completely destroyed, as far as this dam is concerned, as far as the dam is concerned, as short as 3 months, more than 8 months, may not be able to be completed, if you win this time, It is of a strategic nature to China.

A dam, enough to resist an earthquake of magnitude 8 or more, is absolutely impossible to be easily breached, and the dam atomic bomb of later generations can be breached, in this era, the dam is not as good as the later generations, but it is not a conventional weapon can be totaled, fortunately, there are special armor-piercing bullets here, Cheng Biguang has also done a lot of work before, so that the rear has calculated the attack, as long as it is fought according to this, it is a matter of time to destroy.

The Panama Canal as an important passage connecting North and South America has long belonged to the aspect of Chinese research, of course, the main direction of research is to learn from the experience of the dam, in the future, in the Yangtze River, the Yellow River, the Brahmaputra River to build dams, the use of these natural hydraulic resources, but now, it is used for destruction.

The balance of a dam, in addition to its own heavy enough, strong enough, also has a mechanical balance problem, just like a bridge, if you use cannonballs to bombard, you may need countless shells, and it may not be able to collapse a bridge, but if you find the mechanical balance point, as long as the balance is broken, maybe, a little explosive, is enough to destroy a bridge.

The mechanical balance point of the dam, compared to the bridge, is much more stable, it is impossible to destroy a bridge with a little explosives, domestic bridge and architecture experts, or on the huge dam, found 8 weak links, this link, is only the relatively weak place of the dam, as long as these links are attacked, to a certain time, the dam will inevitably be destroyed, according to the calculations of these experts, 4 fantasy class can destroy the dam, but the time will be very long.

This is another attack on a fixed location, under the calculation of the calculator, the accuracy is extremely high, and even because there is not much influence around, the nearest US fleet, the distance is more than 1000 nautical miles, as long as the dam is sealed to prevent people from coming out, they can shoot freely, without worrying about the counterattack of the other side, which is to some extent, more comfortable than attacking New York.
