To take Australia.n∈n∈, there are a lot of preparations and it takes a long time. Australia's strategy is different from the Middle East. It already has Iraq as the foundation. Large areas of deserts in the Middle East have also reduced the difficulty of occupying them. However, in Australia, even if you use East Timor as a springboard to enter Australia, you have just settled down. There is no problem in transportation and escort. However, from western Australia to the east, it is also very difficult. Australia has huge grasslands and deserts in the west. Most of the land of more than 7 million square kilometers are deserts, deserts and grasslands. For the Chinese team that needs supply, it is necessary to ensure supply.

Fortunately, it is a long-term task to guide Australia. First, it is necessary to build a port at the location of Darwin in the future, and then build a solid base. It may take half a year or even a year before it will continue to advance to the inland. Steady and steady progress has always been China's tradition. It is not an advance within the region. It does not have the advantages of railways and supplies, and can only rely on merchant ships. Such supplies are quite fragile. The Allies and Britain and the United States have the confidence to spare no effort to transport under the attack of submarines, and they don't even care about the losses of materials and merchant ships. China does not have such a foundation. Fortunately, Southeast Asia is almost an inside line. Even if the sea route from Guawa Island to Darwin in Australia is not very far, the aircraft set up by China in East Timor is enough to ensure the safety of the waterway.

Only by adding airplanes can the value of the islands be truly demonstrated. If islands were not important in the era of battleships, the reason was very simple. Islands were just embellishments on the ocean. Unless they were particularly outstanding, such as guarding the waterway or an excellent natural harbor, they would not be of great use. At most, some supply points were set up. Many islands in this era occupied casually. Even Germany, which occupied a long time later than Britain and France, occupied a large number of islands in the Pacific Ocean. This is the reason.

Of course, these islands were handed over to China one after another. There was no way, Germany's consumption in the war was getting higher and higher. Some supplements could be spent more, and when they could not continue, they proposed to exchange them. These deserted islands, the Caroline Islands and the Mariana Islands were all occupied casually, with only simple supply points and no construction. However, China gave a good price half-rejection, which allowed Germany to support it under high standards until now.

Yang Yuanzhao was very clear about the important role of islands. In the era of aircraft, islands will become an extension of land. According to the standards of aircraft during World War II, the coverage of an island's roadbed aircraft was more than 300 kilometers. After all, most islands cannot dock four-engine strategic aircraft. However, China is different. As early as the early 20th century, they have mastered the manufacturing methods of long-range strategic aircraft. Even if they do not mention long-range, ordinary aircraft, range and performance, it has exceeded the 20th century. Turboprop aircraft, compared with piston aircraft, can easily reach more than 1,500 kilometers of range, and in this way, the control radius will reach 750 kilometers.

From 300 kilometers to 750 kilometers, this coverage range is more than ten times. As long as it is slightly dense in the island, it will also become the range of aircraft control. If the role of radar is added, now, with the help of all-in-one aircraft, with the rapid progress of radio and semiconductors, China already has a sea radar of more than 600 kilometers that can be detected. Although it can only detect targets above large destroyers, it is enough to make any ship pass through the place it covers, so that the role of the island will be further increased.

It’s just a visit to the Caroline Islands. There are more than 900 islands and reefs, with an area of ​​only more than 1,000 square kilometers, an average of one or two square kilometers. Except for a very small number, the rest cannot be used as bases and airports. They are located in the center of the Pacific Ocean. It is difficult to build fields in the sea and build fields, and the development is too difficult.

But the Mariana Islands are different. The 16 islands have a total of 496 square nautical miles, of which 8 inhabited islands have a foundation for development, and it is no problem to establish an airport at least. The most important thing is that Hiroshima, which belongs to the Mariana Islands, was seized by the United States from Spain. It currently belongs to the United States and will become an existence that defends the Western Pacific in the future.

The Pacific Ocean is different from the Atlantic Ocean, with fewer islands, but the Western Pacific Ocean is a relatively large number of islands. There are many islands in the Pacific Ocean, but Yang Yuanzhao really remembers that it is a few islands such as Guam, Midway Island, and Hawaii.

There is another difference between this. Midway Island is a circular island and reef, a natural port with only 5 square kilometers of land. It can build some small airports and ports, and it is a natural submarine base and warship anchorage. As for Hawaii, it is different from Guam. Hawaii has more than 100 islands with a total area of ​​more than 16,000 square kilometers, which can be a small stronghold. As for Guam, more than 500 square kilometers of land is enough to accommodate large military bases.

These are key islands that were competing between the United States and Japan during World War II. If they entered China one day earlier, they would not only completely control the surrounding waters, but also make the future of Australia's attacks, and at least no one would interfere with their attacks on Australia. It would also make China's flanks more stable, bringing the distance between China and the United States closer to more than 2,500 nautical miles from Southeast Asia, which would reduce transportation costs extremely considerable. Therefore, before attacking the United States, it would take down Guam and Hawaii, a key island in the Atlantic Ocean, which is very critical.

Island countries always need ships and fleets to contact the outside world. When the island is controlled and land-based radars and land-based aircraft are arranged on the island, unless the air force can be completely eliminated, any warship passing by from the side is a very dangerous thing, even battleships or even aircraft carriers. A fixed island with sufficient number of aircraft will become an island that will never sink. With the excellent radar, it can easily prevent attacks. Unless it develops into later generations and uses missile attacks, it will be impregnable.

From East Timor to Australia, there are only a few hundred or thousands of kilometers above the waterway. These are quite safe under the protection of land-based long-range bombers. The Allies are almost impossible to threaten Asian transportation without breakthroughs in ocean submarines. But in the future, war will always be the best catalyst for various technologies. Who knows when the US and British submarines will come out and have to be guarded.

For anti-submarine, destroyers are the best anti-submarine means at present, but Yang Yuanzhao, who is familiar with later history, knows that the best anti-submarine means should be anti-submarine aircraft, which is not only faster, but also has no dead ends. As long as the sonar is discovered by the aircraft, the anti-submarine aircraft can directly attack the submarine by deep-water bombs, which is enough to make the submarine have nowhere to escape.

Anti-submarine aircraft and the like are not something that can appear in this era. Even if the northwest has made the sonar as small as possible, it is at least more than 3 tons, and the size is as big as a few houses. It is not very eye-catching on warships, but it is almost impossible to install on anti-submarine aircraft. It is possible unless the research on sonar enters a new field, and electronic components and computers can make breakthroughs.

Major research institutes in China are conducting research on sonars. Perhaps it is because of the beginning, or because of the excellent research on semiconductors and computers in China. The progress is not slow. Almost every month, a reduction of 3 kg-5 kg ​​can be generated. This speed is not slow, and the reduction is also quite large. However, for huge sonars, it may take 3 or even 5 years to reduce to the level that can be used on aircraft. In any case, the possibility of use in this war is extremely low. Unless a 4-round strategic bomber is used, the speed and safety will not be guaranteed.

Instead of staking time and effort to pin your hopes on unreliable aircraft anti-submarines, it is better to turn on the sonar function to the best. There is enough space on the ship to install a more powerful sonar, so that it will be easier to spot the opponent's submarine.

China is preparing for the troops and setting goals. At this time, there is a different scene in the US Pacific Command in Hawaii. The people at the bottom are constantly busy, but the senior generals are confused. They are afraid that the Chinese will come over. In their opinion, the only thing they can do after the Chinese will come over is to surrender.

It’s not that the Hawaiian defenders are not good. In fact, the Hawaii defenders are already quite powerful. At least in the history of the United States, Hawaii has the largest number of troops. The youngest territory in the United States fell into the hands of the United States around the 20th century. At this time, it has become the largest military port of the United States in the Pacific, but it is too close to Asia. If China uses the attacks from Southeast Asia and the Philippines as an assessment, it should be no problem to take it down.

Now, the United States has only 120,000 people here, more than 50,000 of which were retreated from the Philippines. The mainland of the United States is too far from Hawaii, and they have no way to support it.

The commander of the US military is very clear about this point, and the Chinese side will definitely know that a simple operation is not as simple as Hawaii, which was fortified and ported in World War II, could not resist the attack of China's army power. Once China attacks, it will use at least three times or even five times of its personnel, which is almost completely out of reach. (To be continued.)
