Japan's Matsushima Air Base is located on the coast of Matsushima Bay in Miyagi Prefecture in eastern Japan, about 30 kilometers from Miyagi Prefecture in the southwest, and is a military airfield under the Japan Air Self-Defense Force, and the 3rd Air Regiment of the Japan Air Self-Defense Force is stationed at the Matsushima base.

In addition, the 4th Aviation Training Wing of the Flight Training Corps, the 302nd Squadron Air Rescue Detachment, and the 21st Squadron of the 4th Air Regiment of the Japan Air Self-Defense Force are also stationed at the Matsushima base.

On July 30, 1971, there was also a major aviation accident in which an F86F fighter collided with an All Nippon Airways Boeing 727 over the base.

The tsunami caused by the recent strong earthquake completely inundated the base, and the 18 F2 fighter jets stationed at the base were instantly submerged in the tsunami or pushed by the waves and destroyed, and some missiles were also lost in the tsunami.

……

In the days that followed, the steel hammer ate all the nuclear fuel from the No. 1 to No. 4 nuclear reactors at the Fukushima nuclear power plant, and Chen Xin was already making all kinds of preparations.

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

In the past two days, TEPCO and the Japanese government have jumped very happily, saying that the Fukushima nuclear leak has been completely controlled, the amount of radiation measured every day is steadily decreasing, and TEPCO intends to remove the nuclear fuel rods from the nuclear reactors of units 1 to 4 at the appropriate time, and then dispose of these four units as waste reactors.

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

As the Highlander travels all the way north, the further north it goes, the more damage the earthquake and tsunami do.

Everywhere you can see the remnants of the earthquake and tsunami, shocking, there are also many people wandering near the homes that were washed away by the tsunami, their expressions numb and confused, Chen Xin thought to himself, he helped them avoid the threat of nuclear radiation, and it is a great thing, if the international community knows, should he also send his own Nobel **?

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

When passing by several checkpoints, Chen Xin showed his Reuters press card, and the soldiers of the Self-Defense Forces did not look carefully, waved their hands, and directly let him pass.

After a 300-kilometer journey, Chen Xin spent nearly eight hours to arrive in Dongsongdao City, when it was already the beginning of the lights, and when night fell, Chen Xin went straight to find a hotel to stay, ready to rest for a day and recover his strength.

It was the first time to personally do such a big thing, Chen Xin was still a little nervous, and kept confirming various details of Jihua with to prevent accidents.

According to the photos taken two days ago, the runway at the Songdo base has basically been cleared, and two F-2 fighters that have been almost cleared are parked side by side on the tarmac, which is Chen Xin's target.

………………

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

As early as 1973, the Japanese Defense Agency began to promote the development of future self-made fighters related to the development of jihua, and in 1984, the staff meeting of the Defense Agency reviewed the feasibility of developing its own F-1 support fighter successor (FS-X), and in March 1985, Mitsubishi Heavy Industries proposed the JF-210jihua for the development of independent fighters.

Its appearance is similar to the double-engine and double-vertical tail amplification modification of the Swedish JAS-39 "Gripen", equipped with two F404 engines, with a basic empty weight of 11.5 tons, a maximum speed of Mach 19 per hour, and a combat radius of up to 930 kilometers carrying four anti-ship missiles to carry out anti-ship combat missions.

In October of the same year, due to the huge amount of funds required for self-research and development, there were two additional options in the development direction of FS-X: "conversion of active fighters" and "introduction of foreign fighters" (options: F-15 to change, F-16 to change, F-18 to change, Tornado change).

In December, under the strong political pressure of the United States, the fourth option was released, that is, joint research and development with the United States.

From April to October 1987, the United States and Japan launched a series of related negotiations on the FS-X development case, Japan wanted to jointly develop a new fighter that kept up with the trend of the times, but the United States only wanted to give full play to the economic value of the remaining exploitation sub-colonies of the existing fighters, zuihou, Japan gave in to the colony, based on cost and economic considerations, the two sides decided to choose the F-16CBlock40/42 as the modified aircraft of the FS-X. (Block here refers to the production batch of fighters, followed by F16Block50/52 and F16Block60/62, and the performance of each batch has been greatly improved).

However, the insatiable old United States was not satisfied with this, because it was worried that Japan would take advantage of the opportunity of cooperation with the United States to learn from the world's leading military aviation science and technology of the United States, and wanted to contract FS-X projects as much as possible to increase its own employment opportunities and balance the trade deficit with Japan.

Zuihou Laomei not only did not hand over a number of core scientific and technological secrets to Japan, but also grabbed about 40% of the FS-X component production engineering contract, and even obtained a low-cost active phased array radar unit component production method and an integrated composite wing manufacturing method from Japan, which can be described as a double benefit for both people and money.

You must know that at that time, the unit production cost of the active phased array radar antenna unit in the United States was as high as 8,000 US dollars, and more than 2,000 such units were needed on the AN/APG-77 active phased array radar on the F-22, so if it was produced in the way of the United States at that time, the asking price of the F-22 alone for the radar antenna part would exceed half of the F-16C. The unit production cost of the active phased array radar antenna unit is only 1,000 US dollars, so it is not difficult to understand that the United States Weishenme would covet this Japanese jishu so much.

As for Japan, not only did FS-Xjihua delay it for two years, but the cost also continued to rise, from the initial estimate of 166 billion yen in research and development to 327 billion yen in 1994.

Zuihou has created an autonomous fighter with a unit cost of $107 million and the original Jishu is outdated and has many problems, which can be described as the most humiliating military cooperation project in Japan for more than 20 years, so this fighter jet, known as the "Heisei Zero War", was praised by the Japanese media as "the new zero war born from rape".

In 2004, the Japanese Defense Agency had to decide to stop the follow-up procurement of F-2A/B fighters on the grounds that the cost performance was too low.

In the end, the original Jihua produced 130 F2 fighters and only produced less than 100 and ended hastily.

What's even more speechless is that this is known as the first advanced fighter equipped with an active electrical scanning phased array radar on the shijie, but it continues to break out radar problems, because jishu is not yet mature and rushed to launch, J/APG-1 phased array radar performance is very unstable.

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

Of course, the problems of the F-2 do not stop there, and as the F-2 continues to increase its flight hours, new problems will arise, and the F-2 will remain like a lingering shadow over the Japanese Ministry of Defense.

The only thing that makes the Japanese Ministry of Defense feel comfortable is that through the development of the F-2 fighter, Japan's relatively weak fighter jet overall design and aero engine Jishu have made significant progress, which has also enabled Japan to get rid of the situation of relying on US licenses to copy fighter jets. Through the development of the F-2 fighter, Japan has learned some advanced aviation jishu from the United States, which has greatly promoted the development of its own aviation jishu and laid a solid foundation for the next "Xinshen" fourth-generation aircraft.

Of course, although the F-2 has various shortcomings, the F-2 is still an opponent that cannot be ignored for the Chinese Navy and Air Force.

In fact, the F-2 fighter is one of the few Japanese fighters capable of conducting over-the-horizon air combat and launching anti-ship missiles.

Moreover, not long ago, the Japanese Ministry of Defense put forward a series of budget plans, intending to invest huge sums of money to upgrade the radar and avionics systems of the F15J and F2A/B, so that they can be attached to the AAM-4B medium-range air-to-air missile developed by Japan to strengthen its over-the-horizon air combat capability.

According to the budget documents of the Ministry of Defense in previous years, Japan began research and development work on upgrading the fire control system of the F-2 aircraft as early as 2004, and the budget for fiscal year 2010 has mentioned upgrading the air combat capability of the aircraft. The main content of this upgrade is to upgrade the active phased array fire control radar of the F-2 aircraft from J/APG-1 to J/APG-2, and at the same time integrate AAM-4B medium-range air-to-air missiles for the aircraft.

Both the J/APG-2 radar and the AAM-4B missile were developed by the Ministry of Defense's Jishu Research Headquarters (TRDI), but they also made significant contributions to industrial project contractors, Mitsubishi Heavy Industries (general contractor for the F-2 aircraft) and Mitsubishi Electric Corporation (contractor for the J/APG-1 radar and AAM-4B missile).

The J/APG-2 radar and AAM-4B missiles required for the upgrade will be provided by Mitsubishi Electric, which will be completed by Mitsubishi Heavy Industries during the overhaul of the F-2 aircraft.

The J/APG-2 radar uses a modified J/APG-1 radar antenna with an appropriately modified (details not disclosed) to increase the transmit power, a new, faster signal processor, and 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, and some foreign media speculated that its performance may be comparable to the AN/APG-79 radar equipped with the second batch of US F/A-18E/F fighters.

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