Kitadi Island.

"That's fur seals, and seals."

One of the main reasons for the spread of these animals from the north to the south is the disappearance of small fishing boats along the coastline, which also distracts the animals.

Because it's only the first year, it's just a sporadic animal coming.

"Do you want to get rid of them?"

"Why drive them away?" Wang Hua looked at the seal colony on the coastal reef with a telescope.

Ono really couldn't answer why he wanted to get rid of the seals.

Kitadi Island is about more than 10 square kilometers, located in the gradual zone of the Kuroshio Current and the North Pacific Current, and is also a volcanic island, but it is an extinct volcano, the crater extension has been covered by dense vegetation, the south side of the crater is open, and the sea water enters the crater, because it is mainly affected by the Kuroshio, and is covered in thick fog all year round. It is a traditional fishing ground. Even now, a certain level of fishing is maintained. However, seals did not come here before, mainly because they stinked the coast and reefs, and the Japanese hunted them too hard.

In the past, it was mainly a port for fishermen to anchor and shelter from the wind, but after the construction of a freshwater purification plant on Kitadi Island, people began to settle on the island.

Kitadakishima is high in the north and low in the south, and the seals are located in the reef area to the north. To the south is gentle and densely forested. The resource management institute in the middle has opened up some farmland. There is no shortage of fresh water here in the summer, as the rainfall is abundant. But in winter, the Kuroshio tide recedes southward, and there is less rain and the climate becomes colder. Therefore, a freshwater treatment plant is needed to provide water supply.

Ono has good physical fitness because of the forestry he studied. was recruited into the Land and Resources Management Bureau, and was Wang Hua's assistant, which was regarded as a temporary worker.

Management office, fresh water treatment plant. Fishery administration, docks, some processing plants combined, the island already has more than a thousand people. Among them, the number of management offices is the largest, because in addition to forestry management, there are also marine management offices. All the land, including the seas, is under their control.

The Marine Administration has three maritime surveillance vessels, each of which has a small submarine. There is also a decommissioned retrofit. Large submarines for scientific research.

The Fisheries Administration Office is under the management of the Department of Agriculture. They manage the boats and the fishermen. The division of labor between the forests and the oceans managed by the land management is quite clear.

"Seals, fur seals. Sea lions are animals that can swap sea and land, so don't dislike them for making the reef stink. For example, in some places, animal and bird droppings accumulate and are rich in nutrients. It is a fertilizer that is very much needed on the mainland. At the same time, it is also a necessity for the vegetation on the island. Wang Hua turned his telescope to a piece of beach on the right. More than thirty cargo ships were pouring rocks into the shallow sea, where it was shallow. At low tide it is only two or three meters deep. The highest point where the water can be exposed is called Kitakojima. A flight strip will be built there to connect it to Kitadi Island.

Inside the near-semi-circular harbor, a submarine is restocking with fresh water and food.

That's not a submarine of the management post, but a real military submarine.

Its surface is coated with a pitch-black composite that makes the hull as smooth as a fish, and at the same time absorbs sonic signals. This is very different from the riveted hull of the management office. The whole submarine is in the shape of a long drop, and the huge hull and low control tower actually make the submarine look a little delicate.

Since now there is no ocean-going fleet coming. So the whole island of Kitadi is empty and very quiet.

Wang Hua put down the binoculars and smiled: "What if you said that all the shallow sea plants and shallow water plants grow on the beach?" This bay will become a huge green bay. Maybe we'll be able to see turtles crawl onto the shore. ”

Ono thought for a moment and said, "It's okay for the sea to be warm in the south. I'm afraid not to work in the north. ”

Wang Hua patted Ono on the shoulder and said: "The young man is good, but he has to work harder, the most important thing for the administrator is the body, the administrator is the guardian of the country and the warrior." If the army is an iron-blooded spear, we are the shield of guardianship. ”

Ono smiled and said, "You don't worry about me, I'm Japanese." ”

Wang Hua smiled faintly: "China, only Chinese, yellow, white, and even brown people, are all a family, and the reason why China has been inherited for thousands of years is that it has a culture and mentality that embraces all rivers." Between people, there is equality and mutual respect. Of course, if you don't have self-respect, then it's no wonder us. ”

Ono said: "This is what I like about China, there are very different interpretations of high and low. It is not in terms of status and money, but in terms of cultivation. ”

Wang Hua got up and said, "Let's go, you kid may be better than me in the future, because you are smart enough." But don't overdo it. ”

Ono laughed.

The Zhou-class submarine No. 4 was recommissioned after being reconstructed. The coating has been added and the latest integrated nuclear fission battery pack has been replaced, which is smaller, safer and quieter. The central computer and probing equipment were replaced. The space, which had not been used before, is now known to be used for the installation of submarine-launched missiles. The torpedo tubes were also reworked, and the fat torpedo, now very slim. And instead of conventional torpedoes, small red eggs, the explosion power becomes smaller, and the range becomes longer. The danger of almost filling myself in last time will not happen again. Of course, there will be no big results like last time.

The submarine slowly exited the harbor and entered the North Pacific Current in the south.

One of the important reasons why Kitadakishima will become a military port is that it is the terminus of the Kuroshio, which is like a river in a huge ocean, and the current is much faster than other places. Sailing in the Kuroshio is like getting on a high-speed railway, and when you get to Kitadimajima, the high-speed railway becomes a low-speed railway. The North Pacific Gyre is slower than the Kuroshio Current, but still faster than elsewhere.

Although the Americans have analyzed the existence of ocean currents, they do not know where they are and what kind of laws they have.

Of course, these ocean currents are not always safe, on the contrary, in some places, they become very dangerous due to the chaotic currents. This requires the submarine itself to have adequate detection system support.

The data link of the submarines and the fleets has been completed. What used to be a simple communication is now possible for data transmission. This transmission is mixed with ocean clutter and can be picked up by listening systems in the United States and the United Kingdom. But on the one hand, they think it's clutter and find a way to get rid of it, and on the other hand, they don't have a high-speed computer to analyze and deal with it. They even abandoned the electronic system. Because they have no way to solve the fragility of the tube, there is no way to solve the problem of anti-electronic interference.

The torpedoes and rockets of the Americans received inertial guidance and purely mechanized computers. The design ideas provided by von Kármán also opened the eyes of the electronics and control institutes, because they were almost the pinnacle of mechanical manufacturing processes and design. They insert a data stick engraved with a series of data into a mechanical computer, and then let the computer run according to the dots on the data stick, like a gramophone. Finally, the rocket is allowed to fly according to the trajectory. In this way, it can be completely free from external interference.

The Americans have not yet found a way to turn a rocket into a smart missile. Von Kármán thought of using an electronic computer, but was denied.

And when von Kármán saw that the Chinese had completely abandoned the tube and used a chip or even optical transmission, he slapped his head. Because these thoughts once flashed in his mind, but he gave up because of the manufacturing technology, the cost, and the lack of financial support.

The information system has caused a serious information asymmetry between China and the United States.

Li Chunpeng is completely capable of fighting guerrilla warfare with US submarines, while US submarines can neither see nor hear. It is only possible to sweep the oceans with numerical superiority, and this is a huge drain. It consumes manpower, consumes money, consumes fuel.

And most of the American conglomerates are secretly rejoicing in this, because it has brought a huge market for their products and won them countless fortunes.

"Found a pack of wolves, dived to a depth of one hundred and fifty meters, a total of six, and the speed was five knots. They're stalking us. "The news came from the command ship of the Izu fishing fleet.

China's fishing fleet is so large that it can already compete with the U.S. fleet other than aircraft carriers because it is fully equipped. The Izu fishing fleet is too close to Midway,

However, it is still far from Li Chunpeng.

"Leave them alone, we'll pass them on and go back along the California Current, which is the most fuel-efficient and rewarding option. These submarines are too slow to keep up with us. ”

This is the answer of the command ship.

Li Chunpeng was excited: "Let's ambush them." They have a limited endurance and will definitely have to go back to port, and we will give it a hit near Pearl Harbor. (To be continued......)
