Diaoyu Island.

After several months of intense construction, the Diaoyu Islands have been completely unrecognizable, and a large radar station has begun to be put into use on the main peak of the Diaoyu Islands, monitoring every move in the air for several hundred kilometers centered on the Diaoyu Islands, and the most important purpose of this radar station is, of course, to keep a close eye on the entry and exit of F-22 and F-35 fighters at the US military base in Naha in the Ryukyus.

Nail the fourth-generation fighters at the US military's Naha base will be able to make up for our military's shortcomings in the fourth-generation fighters, form a powerful radar network with ground and air early warning planes, and see the US military's fourth-generation planes to the death, and cooperate with the theater joint combat system of the Air Force fighters to be able to use our third-generation aircraft cluster to counter the US military's fourth-generation aircraft.

Therefore, this small island, which is more than 300 kilometers ahead of the mainland, has an irreplaceable strategic role in guarding against a sudden attack by US stealth fighters.

It is precisely because of this that when the People's Liberation Army (PLA) resolutely seized the Diaoyu Islands in one fell swoop, it immediately plunged into intense construction, and when the submarine was in the midst of a secret battle with the Japanese submarines, it was a hot construction scene here, and after the naval engineering unit quickly opened up a temporary 5,000-ton large wharf on the west side of the island, a large number of large machinery and equipment were transported to the island to begin large-scale combat readiness construction.

Even though the Japanese protested every day, there was a fleet of escorts and submarines cruising around the Diaoyu Islands at that time, and the Japanese who were not ready for war could only protest.

The PLA engineering troops, which are good at creating miracles, took about a month to complete the main earthwork operations, and then the Duke Shenlong plan successfully developed the latest Tianyan-10 meter-wave radar using long meter-wave technology, and this new stealth fighter nemesis became the military's first choice, and was the first to be installed on the Gaohua Peak in the west of the island.

This latest domestic meter-wave radar, which embodies Duke's intelligent pattern recognition technology, can effectively undertake the search and alert task of anti-air stealth fighters. According to the internal test results, the Tianyan-10 meter-wave radar can effectively find air targets with a range of 500 kilometers, a flight altitude of 100~7500 meters, and a radar cross-section of 0.1 square meters to 0.3 square meters.

Although the air target tracking and location data provided by the Sky Eye-10 radar is not accurate enough, and the error is as high as tens of meters, it cannot directly guide the air defense and air-to-air long-range missile fire to launch a direct attack, but it can effectively discover the enemy's stealth aircraft movements.

With this general range, our military will be able to use the Air Police-2000 early warning aircraft and multi-base ground radars to form a network of heaven and earth to locate the accurate location of stealth aircraft, and then guide air fighter groups or ground long-range air defense firepower to launch over-the-horizon attacks on the enemy's stealth fighters through the theater joint combat tactical system.

In addition to the Tianyan-10 large meter-wave radar, our army has also installed the Sentinel-1 radar system on the island, which is a passive detection system for low-altitude penetrating aircraft and sea surface ships, using "passive coherent positioning" technology, capable of tracking aircraft, helicopters, sea surface ships, cruise missiles and ballistic missiles and other targets, using a multi-plane array structure.

Each plane array can cover 105 ° azimuth, elevation angle 50 °, lateral angle of view 60 °, the use of 6 plane arrays can almost achieve 360 ° all-round coverage, the sea-to-air tracking distance of more than 200 kilometers, due to the use of SAL company's latest successful G2 small computer cluster system, this Sentinel-1 radar system can track 300 different targets at the same time, if linked to digital air defense fire, it can also command the simultaneous attack of 36 sea or air targets.

At this moment, on the Diaoyu Island, 2 sets of Hongqi-9B long-range air defense missile systems and 6 sets of Hongqi-16 short-range air defense systems have been installed, forming a complete set of air defense systems, Hongqi-16 can effectively cover 1.5 kilometers to 20 kilometers, and effectively shoot short-range airspace from 10 meters to 6000 meters high, while Hongqi-9B can attack airspace targets up to 250 kilometers and up to 40 kilometers, and the combination of the two can effectively prevent possible missile attacks and air attacks by opponents.

In order to protect these facilities, the military has also invested a battalion of elite marines, two Wuzhi-10 helicopter gunships, and a small fleet consisting of a Jiangwei II frigate, two Haiqing-class anti-submarine frigates, and four 022-class missile boats.

Since the People's Liberation Army (PLA) took the Diaoyu Islands, the Japanese have long been clamoring to take them back by force, but because the main force of the US military has not been able to move in place, it has been very difficult for the four major escort groups of the Japanese to defend the vast sea territory from the mainland to the Ryukyu Islands.

In this case, it is obviously too reluctant to let the Japanese send out a group of escort teams to carry out the recapture of the Diaoyu Islands, but when the six major aircraft carrier fleets of the US military are in place, the Japanese invaders began to become active, first harassing and provoking with submarines, but after the Chinese side quickly improved the sonar system and invented a new Tiger Shark miniature ramming submarine tactics, the Japanese invaders paid the cost of directly sinking two submarines and damaging more than 10 submarines to varying degrees, and they no longer dared to play this kind of collision game with the PLA submarine force.

But at the Haizi Command, a bold plan to sneak attack the Diaoyu Islands gradually took shape.

On May Day in 2019, immersed in the small Golden Week, the mainland is full of tourists, due to the return of Taiwan Island to negotiate a preliminary agreement, Taiwan Island has completely opened up the Taiwan Island tour project, so that the jubilant mainland people flock to it, and dozens of large passenger ships in southern Fujian frequently come and go between the mainland and Taiwan Island every day. The people of Taiwan Island, who originally had a slight opinion on the return, saw that the mainland people were so enthusiastic, which drove the island's tourism economy to rise sharply, and gradually joined the carnival of this Golden Week.

No one expected that the 2nd Escort Group of the Japanese Invaders, which claimed to be heading south to conduct joint military exercises with Filipino maids in the South China Sea, suddenly turned around and went straight to the Diaoyu Islands when they reached the vicinity of Yonaguni Island, the southwesternmost part of the Japanese Invaders!
