Take Australia. There is a lot of preparation that needs to be done, and it takes a long time. Australia's strategy is different from the Middle East, there is already Iraq as a foundation, the Middle East has a large area of desert, but also makes it less difficult to occupy, but in Australia, even with the help of East Timor as a springboard, into Australia, it is only just a foothold, in the transportation and escort, there is no problem, from the west to the east of Australia, it is also very difficult, Australia has a huge grassland, in the west also has a desert, more than 7 million square kilometers of land, most of which are uninhabited deserts, Deserts and grasslands, which must be guaranteed for the Chinese army in need of supplies.

Fortunately, it is a long-term task to attack Australia, first of all, it is necessary to build a port in the location of Darwin in the future, and then it is to build a solid base, which may be built for half a year, or even a year, before it will continue to march inland, and it has always been a Chinese tradition to march steadily, not to march in the region, without the advantage of railways and supplies, and to be able to rely only on merchant ships, such supplies are quite fragile, and the Entente and Britain and the United States have the confidence to spare no effort to transport under the attack of submarines. China doesn't even care about the loss of supplies and merchant ships, China doesn't have such a background, but fortunately, Southeast Asia is almost an internal route, even if the sea route from Guawa Island to Darwin, Australia is not very far, with the planes set up by China in Timor-Leste, it is enough to ensure the safety of the shipping lane.

If the island plus the plane can really show the value of the island, if in the era of battleships, the island is not important, the reason is very simple, the island is just an embellishment on the ocean, unless it is particularly good, such as guarding the waterway. Or an excellent natural harbor, otherwise it is of little use, at most set up a little supply point and so on, in this era, many islands were occupied casually, even long later than Britain and France occupied the colony. All in the Pacific Ocean, occupying a large number of islands, and that's why.

Of course, these islands have been handed over to China one after another, and there is no way, Germany's consumption in the war is getting higher and higher, and some supplements can be spent more, when there is no way to continue. These desert islands, the Caroline Islands and the Mariana Islands, were all occupied casually, with only simple supply points, and no construction was even built, but China gave a good price half-pushed, which allowed Germany to be under high standards. Supported until now.

Yang Yuanzhao is very aware of the important role of the island. In the era of aircraft, the island will become an extension of the land, according to the standards of the aircraft during World War II, the coverage range of an island's roadbed aircraft is more than 300 kilometers, after all, most of the islands, there is no way to dock four strategic aircraft. But China is different, as early as the beginning of the 20th century, it has already mastered the method of manufacturing long-range strategic aircraft, even if not long-range, ordinary aircraft. In terms of range and performance, it also exceeds the period of World War II, turboprop aircraft, compared with the natural advantages of piston aircraft, so that the range of ordinary light and medium aircraft can easily reach more than 1500 kilometers, so that the control radius will reach 750 kilometers.

From 300 kilometers to 750 kilometers, this coverage range is more than ten times, as long as the island is slightly dense, it will also become the range of aircraft control, if you add the role of radar, now, with the help of all-in-one machine, under 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 find targets above large destroyers, but it is enough for any ship to pass through the place he covers as a luxury, In this way, the role of the island is further increased.

The Caroline Islands are also here, more than 900 islands and reefs, a total area of only more than 1,000 square kilometers, an average of one or two square kilometers, except for a very few, the rest can basically not be used as a base and airport construction, located in the center of the Pacific Ocean, it is difficult to reclaim the sea and make land, and it is too difficult to develop.

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

The Pacific Ocean is different from the Atlantic Ocean, and the islands are relatively scarce, but the Western Pacific Ocean belongs to the many islands, and there are many islands in the Pacific Ocean, but Yang Yuanzhao really remembers that there are a few islands such as Guam, Midway, and Hawaii.

There is a difference, Midway is a atoll, a natural port, only 5 square kilometers of land, can build some small airports and ports, is a natural submarine base and warship anchorage, as for Hawaii and Guam is different, Hawaii has more than 100 islands, with a total area of more than 16,000 square kilometers, it can simply become a small stronghold, as for Guam, more than 500 square kilometers of land, enough to accommodate a large military base.

These are the key islands in the struggle between the United States and Japan during World War II, if they enter the hands of China one day earlier, not only can they completely control the surrounding waters, but also make the future, for Australia's attack, completely safe, at least no one will interfere with their attack on Australia, and can also make China's flank more stable, and shorten the distance between China and the United States from Southeast Asia by more than 2,500 nautical miles, which reduces transportation costs considerably. So before attacking the United States, it is very important to take Guam and Hawaii, which are key islands in the Atlantic Ocean.

Island countries, always need ships and fleets to communicate with the outside world, when the island is controlled, and land-based radar and land-based aircraft are arranged on the island, unless the air force can be completely eliminated, any warship passing by the side, it is a very dangerous thing, even if it is a battleship, even an aircraft carrier, a fixed, with a sufficient number of aircraft island, will become an unsinkable island, plus the excellent radar, can easily prevent attack, unless it is developed to the future, with missile attack, Otherwise, it's going to be impregnable.

From East Timor to Australia, there are only a few hundred kilometers on the waterway, these are under the protection of land-based long-range bombers, quite safe, the Entente countries in the ocean-going submarine has not broken through the premise, it is almost impossible to threaten Asian transport, but in the future, war will always be the best catalyst for all kinds of science and technology, who knows when, the United States and British submarines will come out, have to be guarded against.

As far as anti-submarine is concerned, destroyers are the best anti-submarine means at present, but Yang Yuanzhao, who is familiar with the history of later generations, 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 it is discovered by the sonar carried by the aircraft, the anti-submarine aircraft can directly attack the submarine with depth charges, which is enough to make the submarine have nowhere to escape.

Anti-submarine aircraft and the like, it is really not something that can appear in this era, even if the northwest has made sonar miniaturized as much as possible, but at least it is still more than 3 tons, and the volume is the size of several houses, on the battleship, it is not very conspicuous, but it is installed on the anti-submarine aircraft, it is almost impossible, unless the research on sonar enters a new field, plus electronic components and computers can make breakthroughs, it is possible.

China's major research institutes, is conducting research on sonar, perhaps because of the beginning, perhaps because of the excellent relationship between China's semiconductor and computer research, the progress is not slow, almost every month, can produce 3 kg - 5 kg reduction, such a speed is not slow, the reduction is also quite huge, but for the huge sonar, if you want to reduce to the extent that it can be used on the plane, it may take 3 years or even 5 years, anyway, the possibility of using it in this war is extremely low, Unless a strategic bomber with four rounds is used, the speed and safety cannot be guaranteed.

Instead of wasting time and effort to pin hopes on unreliable aircraft anti-submarine warfare, it is better to turn on the function of sonar to the best, and there is enough space on the ship to install more powerful sonar, so that it is easier to detect the opponent's submarine.

On the Chinese side, when preparations are being made for the dispatch of troops and the goals are set, at this time in Hawaii, in the US Pacific Command, it is a different scene, the personnel at the bottom are constantly busy, but the high-level generals are confused, they are afraid that the Chinese will call, in their opinion, after the Chinese fight, the only thing they can do is surrender.

It's not that the Hawaiian garrison can't do it, in fact, the Hawaiian garrison is already quite strong, at least in the history of the United States, the number of Hawaiian troops is the first. Hawaii, the youngest territory in the United States, only fell into the hands of the United States around the 20th century, and at this time, it has become the largest military port of the United States in the Pacific, but it is too close to Asia, and if China takes the attacks in Southeast Asia and the Philippines as an assessment, it should not be a problem to take this place.

Now, the United States only has 120,000 people here, of which more than 50,000 have been evacuated from the Philippines, and the American mainland, which is too far away from Hawaii, is too far to support here.

The commander of the US military is very clear about this, and the Chinese side will definitely know that Hawaii, which is just a simple operation and is not like the fortified and portified Hawaii during World War II, will not be able to resist the attack of China, a land power, and once China comes to attack, it will at least use three or even five times as many personnel, which is almost completely impossible to fight.
