Japan's Matsushima Air Force Base is located on the coast of Matsushima Bay, Miyagi County in eastern Japan. It is about 30 kilometers away from Miyagi County in the southwest. It is a military airport under the Japan Air Self-Defense Force. Stationed in Songdo base.

In addition, the 4th Aviation Training Wing of the Flight Training Corps, the Air Rescue Unit of the 302nd Squadron, and the "Blue Shockwave" aerobatic team of the 21st Squadron of the [-]th Aviation Regiment of the Japan Air Self-Defense Force are also stationed at the Songdo Base.

1971年7月30曰,在此基地上空还发生过f86f战斗机与全曰航空公司的波音727客机碰撞的重大航空事故。

The tsunami triggered by a strong earthquake not long ago completely submerged the base. The 18 F2 fighter jets stationed at the base were instantly submerged or damaged by the tsunami, and some missiles were also lost in the tsunami.

In the next few days, Gang Yi ate up all the nuclear fuel in nuclear reactors 1 to 4 of the Fukushima Nuclear Power Plant, and Chen Xin had already made various preparations.

He obtained a senior press card from Reuters through steel coins, and rented a Toyota Highlander from a car rental company as Ichiro Watanabe, and planned to drive straight to Miyagi Prefecture, 300 kilometers northeast of Tokyo. Matsushima City.

In the past two days, Tepco and the Japanese government have been very happy, saying that the Fukushima nuclear leak has been completely controlled, and the radiation measured every day is steadily decreasing. The nuclear fuel rods in the Unit [-] nuclear reactor are then scrapped for these four units.

It's just that if they see the four nuclear reactor units with only a pile of empty shells left, they don't know what expressions they will have on their faces. Chen Xin is very much looking forward to it.

As the Highlander made its way north, the further north the earthquake and tsunami wreaked havoc.

The remnants of the earthquake and tsunami can be seen everywhere, which is shocking. There are also many people lingering near the homes destroyed by the tsunami, with numb and confused expressions. Chen Xin thought, if he helped them avoid the threat of nuclear radiation, he was also counted as a This is a great thing, if the international community knows about it, shouldn’t it be awarded a Nobel Prize?

Due to the damage of the earthquake and tsunami, many roads have been damaged. Fortunately, with the real-time satellite map navigation provided by Gangzheng, Chen Xincai was not blocked on the road.

When passing through several checkpoints, Chen Xin showed his Reuters press card, but the soldiers of the Self-Defense Forces waved their hands and let him pass without looking carefully.

It took Chen Xin nearly eight hours to reach East Songdo City on the 300-kilometer journey. At that time, it was already the beginning of the lights, and as night fell, Chen Xin went straight to find a hotel to stay in, ready to take a good rest and recover his strength.

It was the first time for Chen Xin to do such a major event by himself, and he was still a little nervous. He kept confirming various details of the plan with Gang Bian to prevent accidents.

According to the photos of the previous two days, the runway of the Songdo Base has basically been cleared, and two f-2 fighter jets that have been cleared are almost parked side by side on the tarmac. This is Chen Xin's goal.

The Mitsubishi F2 fighter jet is one of the main types of fighter jets under the Japanese Air Self-Defense Force. It is a high-performance multi-purpose fighter jet jointly developed by Mitsubishi Heavy Industries and Lockheed Martin Corporation of the United States on the basis of the F-16C.

As early as 1, the Japan Defense Agency began to promote the development of related technologies for the future self-made fighter R&D plan. In 210, the Defense Agency staff meeting reviewed the self-developed f-[-] support fighter successor model (fs-x ), and in March [-], Mitsubishi Heavy Industries proposed the jf-[-] plan for independent fighter research and development.

Its appearance concept is similar to that of the Swedish Jas-39 "Gripen", which is an enlarged version with twin engines and double vertical tail fins. It is equipped with two F404 engines, has a basic empty weight of 11.5 tons, a top speed of Mach 930, and carries four anti-ship missiles. The combat radius of anti-ship combat missions can reach [-] kilometers.

In October of the same year, due to the huge amount of funds required for self-development, the development direction of fs-x appeared again "converting active fighters" and "importing foreign fighters" (options: f-15 modification, f-16 modification, f- 18 Kai, Tornado Kai) two additional options.

In December, under the strong political pressure of the United States, the fourth option was released, which is to jointly develop with Laomei.

From April to October 16, the United States and Japan launched a series of related negotiations on the fs-x development project. Japan wanted to jointly develop a new fighter that kept up with the trend of the times, but the old and the United States only wanted to make full use of the remaining fighters in service. Exploiting the economic value of the sub-colonies, in the end, the Japanese sub-colonies succumbed, based on cost and economic considerations, the two sides decided to choose f-40cblock42/16 as the transformation machine of fs-x. (Here block refers to the production batch of fighter jets, followed by f50block52/16, f60block62/[-], the performance of each batch has been greatly improved).

However, the insatiable Lao Mei was not satisfied with this, because she was worried that Japan would use the fs-x project to cooperate with the U.S. to learn from the old U.S.’s world-leading military aviation technology, and wanted to contract as many fs-x projects as possible In order to increase the employment opportunities of the country and balance the trade deficit with Japan, the Japanese colony retreated steadily and kept yielding.

In the end, Laomei not only failed to hand over a number of core technological secrets to Japan, but also grabbed about [-]% of the fs-x component production engineering contract, and even got a low-cost active phased array radar unit from Japan. The component production method and the composite wing manufacturing method of integrated molding can be described as a double benefit of human resources and wealth.

We must know that the unit production cost of the active phased array radar antenna unit in the United States was as high as 22 US dollars at that time, and the an/apg-77 active phased array radar on the f-2000 required more than 22 such units, so if the old Produced in a beautiful way, the asking price of the radar antenna part of the F-16 alone exceeds half of the F-[-]C.Using Japan's exclusive production technology, the unit production cost of the active phased array radar antenna unit is only one thousand dollars. It is not difficult to understand why Lao Mei covets this Japanese technology so much.

As for Japan, not only has the fs-x program been delayed for two years, but the cost has continued to rise steadily. From the initial estimate of 1660 billion yen in research and development funds, by 3270 it had already cost [-] billion yen.

In the end, an autonomous fighter with a unit cost of 1.07 million U.S. dollars and outdated original technology and constant faults can be described as Japan’s most humiliating military cooperation project in more than 20 years. Therefore, this so-called "Heisei Zero War" fighter It was hailed by the Japanese media as "a new zero war born of strong-annihilation".

By 2, the Japanese Defense Agency had to decide to stop the follow-up purchase plan of f-[-]a/b fighter jets on the grounds that the price-to-price ratio was too low.

In the end, the original plan to produce 130 F2 fighters produced less than a hundred and ended hastily.

What is even more speechless is that this advanced fighter jet, which claims to be the first in the world to be equipped with an airborne active electronically scanned phased array radar, continues to have problems with the radar. Since the technology is not yet mature, it hastily launched, j/ apg-1 phased array radar can be very unstable.

During the flight training, the pilot found that the detection range of the F-2 radar sometimes shortened sharply, and the target aircraft had entered the line of sight, but the target was still not displayed on the radar. Sometimes the radar captured the target, but suddenly disappeared on the screen up.Some pilots found that the f-2 had captured the target, and when it was preparing to launch the missile, the target disappeared from the radar again in the tracking mode.

F-2's problems are of course more than these. With the continuous increase of F-2's flight hours, new problems will appear. F-2 is like a lingering shadow that has been hanging over the Japanese Ministry of Defense.

The only thing that comforts Japan's defense ministry is that through the development of the f-2 fighter jet, Japan's relatively weak fighter overall design and aero-engine technology have made significant progress, which also freed Japan from relying on American licenses to imitate fighter jets status.Through the development of the F-2 fighter jet, Japan learned some advanced aviation technology from the United States, which greatly promoted the development of its own aviation technology and laid a solid foundation for the next "Mind" fourth-generation aircraft plan.

Of course, although f-2 has various shortcomings, but for the Chinese navy, air force, navy and air force, f-2 is still an opponent that cannot be ignored.

In fact, the f-2 fighter jet is one of the few fighter jets in Japan that can conduct beyond visual range air combat and launch anti-ship missiles.

And not long ago, the Ministry of Defense of Japan proposed a series of budget plans, intending to invest huge sums of money to upgrade the radar and avionics systems of f15j and f2a/b, so that they can be mounted on the aam-4b medium-range air defense system independently developed by Japan. Air-to-air missiles, strengthening its beyond-visual-range air combat capability.

而根据防卫省往年的预算文件,曰本早在2004年就开始了f-2飞机火控系统升级的研究与开发工作,2010财年的预算已经提及了对该机的空战能力进行升级。此次升级的主要内容是把f-2飞机的有源相控阵火控雷达由j/apg-1升级为j/apg-2,同时为该机综合aam-4b中距空空导弹。

j/apg-2雷达和aam-4b导弹均由防卫省技术研究本部(trdi)研发,但它们在工业界的项目合同商——三菱重工业公司(f-2飞机的总承包商)和三菱电机公司(j/apg-1雷达和aam-4b导弹的承包商)也作出了可观的贡献。

The j/apg-2 radar and aam-4b missile required for this upgrade will be provided by mitsubishi electric, and the upgrade will be completed by mitsubishi heavy industries during the overhaul of the f-2 aircraft.

The j/apg-2 radar adopts the j/apg-1 radar antenna after proper modification (details not disclosed), which increases the transmission power, replaces it with a new type of faster signal processor, and adopts a new processing algorithm .

The Ministry of Defense refused to disclose the detailed performance of the radar, and also refused to compare the radar with foreign radars. Some foreign media speculated that its performance may be the same as that of the second batch of American F/A-2E/F fighter jets. apg-18 radar quite.

Therefore, Chen Xin's target this time is those F2B fighter jets that have completed the radar upgrade and modification work.
