Equipment, armament and combat composition of the Japanese Air Force: history and modernity. Japanese Air Force: the transition to industrial self-sufficiency Japanese aircraft of the First World War

who shook the world

Roll-out by the Japanese of the first airliner in the last half century MRJ forced to look at the previous successes of the Japanese in the aircraft industry. Now the role of Japan in the aircraft industry seems insignificant, but in XX century, the Japanese were among the six leading powers that determined the entire world aircraft industry (still the USA, the USSR, England, Germany, France). The role of other powers outside of this six was really insignificant - less than 10% of the total output falls on them. Yes, now the Japanese make few aircraft (in pieces), but we should not forget that the same Dreamliner is 35% made in Japan, and this is already about many hundreds of "conditional" aircraft!

Magazine « Flight » presented the traditional flash mob on the 10 most notable in history modern aviation Japanese aircraft

NAMC YS-11

40-seat passenger YS -11, produced by the corporation NAMC , turned out to be the last Japanese passenger liner before the "saga of MRJ ". Its production ended 40 years ago, but at least 17 aircraft of this type are still in operation - 15 by the Japanese Ministry of Defense, and two by the Mexican firm Alon.

Mitsubishi MRJ

Rolling out a week ago - on October 18, a 96-seat Mitsubishi regional airliner marked new era in the Japanese aircraft industry. The first flight is scheduled for the first quarter of 2015. In total, Mitsubishi has collected orders for 191 aircraft with deliveries starting in 2017. Another 76-seat modification is planned MRJ 70, but nothing has been heard about the 100-seater for a long time - after numerous delays with the main project, the Japanese are not up to it.

How many opponents of the Sukhoi Superjet were howling when the Japanese were just announcing their plans: “How can we compete with the Japanese and Chinese? The Japanese have plastic, cooperation and all that. And what do we have after the “successful” perestroika collapse?”

However, ten years have passed, the Japanese missed all the deadlines, the prototype aircraft had to be redone from scratch, as they failed with certification (which means a break of 50 years!). “And these people forbid us to pick our noses”?!

Honda NA-420

This aircraft of an unusual layout with engines on pylons on the wing (before that only the Germans did this) and a smooth plastic skin is now undergoing certification tests. Four aircraft are currently flying and certification is expected in the first quarter of 2015. Series production is scheduled at the Greensboro plant in the United States. Now the portfolio of orders for 18 aircraft from the US and Mexico.

Mitsubishi F-2

Outwardly, this Japanese fighter is similar to the American F -16, which is not surprising, since it was created in cooperation with the Americans. But structurally - made of plastic - it is strikingly different from the prototype. Now there are 78 aircraft of this type on the wing, and Mitsubishi is already thinking about a new fighter ...

Shinmaiwa US-2

Amphibian US -2 is designed for search and rescue operations of the Japan Self-Defense Fleet, and is a logical development of the previous amphibian - US -1, which is still in service. FROM US -2 is connected with a serious breakthrough of the Japanese in the military aviation market - about 18 aircraft are planned to be ordered by the Indians.
General US -2, judging by the Sokolyansky formula, is now the most seaworthy flying boat.

Kawasaki R-1

The R-1 jet maritime patrol aircraft developed by Kawasaki is designed to replace the obsolete American R-3 Orions. Japanese "self-defense" has already received two experienced XP-1 and five production aircraft.

Mitsubishi Mu-2

This small twin-engine superplane, which carried only 14 people, first flew in 1962, but nevertheless, 287 of these aircraft still fly.

Mitsubishi Mu-300 "Diamond"

On the wave of success Mu -2 Mitsubishi decided to create a business jet Mu -300. The aircraft first took to the air in 1978. The rights to it were acquired by the American company Beechcraft, which “rebranded” it into the Beach 400. Now there are still 56 "Diamonds" flying, mainly in the USA, and only one flies in Japan Mu -300, which has been used for 30 years as a flying laboratory.

Kawasaki XC-2

The S-2 aircraft is being created as a replacement for the S-1 self-defense forces and Hercules. The Japanese answer to all sorts of "globemasters" and "Atlantis". Features a twin-engine layout. The maximum carrying capacity is expected to be 37 tons. And the S-1 left 27 copies.

Mitsubishi A6M "Zero"


What is the story about the "Japanese" without "Zero"? Even if it has long been a "historical" aircraft. In turn, he completely changed the view of the "West" on Japanese aviation, and struck opponents with maneuverability, rate of climb and lightweight construction. Every twentieth aircraft in the history of Japan is one of 11,000 Zeros. Why, “historical” - several copies are still flying, and “zerobuilding” continues ...

Since the end of World War II, the Japanese military-industrial complex has not shined with the “pearls” of its military industry, and was entirely dependent on the imposed products of the American defense industry, whose powerful lobby was carried out by the Japanese authorities due to the direct dependence of capital and pro-American sentiments in the mentality of the top of society.

A striking example of this is modern composition Air Force (or Air Force self-defense): these are 153 F-15J units (a complete copy of the F-15C), 45 F-15DJ units (a copy of the two-seater F-15D). On the this moment it is these machines, built under an American license, that form the quantitative backbone of aviation for gaining air superiority, as well as suppressing air defense, the use of AGM-88 "HARM" PRLR is provided for on aircraft.

The rest of the fighter-reconnaissance aviation copied from the United States is represented by the F-4EJ, RF-4EJ, EF-4EJ aircraft, of which there are about 80 in the country's Air Force, now they are being gradually removed from service. There is also a contract for the purchase of 42 F-35A GDP fighters, which are an improved copy of the Yak-141. RTR aviation, like the leaders in Europe, is represented by E-2C and E-767 aircraft.

December 18, 2012 Japanese F-2A escorts the latest Russian naval reconnaissance aircraft Tu-214R

But in 1995, the Japanese military pilot E. Watanabe took to the air a completely new combat vehicle, which can now be safely classified as a 4 ++ generation. It was the first prototype of the XF-2A multi-role fighter F-2A, and the subsequent two-seat F-2B. Despite the strong similarity of the F-2A with the American F-16C Block 40, namely, it was taken by Japanese engineers as a reference model, the F-2A was a relatively new technical unit.

Most of all, this affected the airframe and avionics. The nose of the fuselage is a purely Japanese development using a new geometric idea that is different from the Falcon.

It boasts the F-2A and a completely new wing with a lower sweep, but 1.25 higher aerodynamic lifting coefficient (carrying property): the Falcon's wing area is 27.87 m 2, for the F-2 - 34.84 m 2 . Thanks to the increased wing area, the Japanese embodied in their fighter the ability to "energy" maneuver in the BVB in the steady turn mode at a speed of about 22.5 deg / s, as well as reduce fuel consumption during high-altitude combat duty in the complex island grid of Japan. It also became possible thanks to the use of advanced composite materials in the airframe elements of the new aircraft.

The increase in maneuverability was also influenced by big square elevators.

The nacelle remained standard for the Falcon, since it was decided to use the General Electric F110-GE-129 turbojet afterburner engine with a maximum thrust of 13.2 tons. Note that the capacity of the internal fuel tanks is 4675 liters, and 5678 - with the suspension of 3 PTB. The latest American F-16C Block 60 has only 3080 liters in internal tanks. The Japanese made a very wise move: referring to their defensive nature of the aircraft, in cases of conflict, within Japan only, they made it possible for the F-2A to have more fuel on board, and maintain maneuverability on high level without using massive PTB. Due to this, a higher combat radius of action, which is about 830 km against 580 for the Falcon.

The fighter has a practical ceiling of more than 10 km, flight speed at high altitude is about 2120 km/h. When installing 4xUR AIM-9M (4x75kg) and 2xUR AIM-120C (2x150kg) and 80% filled internal fuel tanks (3040l), the thrust-to-weight ratio will be about 1.1, which even today is a strong indicator.

The avionics, at the time the fighter entered the Air Force, gave odds to the entire Chinese fleet. The aircraft is equipped with a Mitsubishi Electric multi-channel noise-immune radar with J-APG-1 AFAR, the antenna array of which is formed by 800 PPM made of GaAs (gallium arsenide), which is the most important semiconductor compound used in modern radio engineering.

The radar is capable of carrying out a "tie" (SNP) of at least 10 target routes, and firing 4-6 of them. Considering that in the 1990s the PAR industry was actively developing in the Russian Federation and other countries, it can be judged that the radar operating range for a fighter-type target (3 m 2) is no more than 120-150 km. However, at that time, AFAR and PFAR were only on the French Rafale, our MiG-31B and the American F-22A.

Airborne radar J-APG-1

The F-2A is equipped with a Japanese-American digital autopilot, a Melko electronic warfare system, communications and tactical situation data transmission devices in the short and ultrashort wave bands. The inertial navigation system is built around five gyroscopes (the main one is laser, and four backup mechanical ones). The cockpit is equipped with a high-quality holographic indicator on the windshield, a large tactical information MFI, and two monochrome CRT MFIs.

The armament is almost identical to the American F-16C, and is represented by AIM-7M, AIM-120C, AIM-9L,M,X; It is worth noting the prospect of the Japanese AAM-4 air-to-air missile system, which will have a range of about 120 km and a flight speed of 4700-5250 km / h. It will be able to use a fighter and guided bombs with PALGSN, ASM-2 anti-ship missiles and other advanced weapons.

Now the Japan Air Self-Defense Force has 61 F-2A and 14 F-2B fighters, which, along with AWACS and 198 F-15C fighters, provide good air defense for the country.

In the 5th generation fighter aviation Japan is already “walking” on its own, which is confirmed by the Mitsubishi ATD-X project “Shinshin” (“Shinshin”, which means “soul”).

Japan, like every technological superpower, by definition must have its own stealth fighter to gain air supremacy; the beginning of work on the magnificent descendant of the legendary A6M Zero aircraft started back in 2004. We can say that the employees of the Technical Design Institute of the Ministry of Defense approached the stages of creating nodes new car in a different plane.

Since the Xingxing project received its first prototype much later than the F-22A, and, undoubtedly, all the shortcomings and errors that the Russians, Americans and Chinese learned from were taken into account and eliminated, and all the best aerodynamic ideas for implementation of ideal performance characteristics, the latest developments in the avionics database, where Japan has already succeeded.

The first flight prototype ATD-X scheduled for winter 2014-2015. Only for the development of the program and the construction of an experimental machine in 2009, an allocation of 400 million dollars was allocated. Most likely, the Xingsin will be called the F-3, it will enter the troops no earlier than 2025.

Shinshin is the smallest fifth-generation fighter, yet the expected range is about 1800 km

What do we know about Xingsin today? Japan is a small power, and does not plan to independently participate in major regional wars with the Self-Defense Air Force, sending its combat aircraft thousands of kilometers deep into enemy territories, hence the name of the Self-Defense Armed Forces. Therefore, the dimensions of the new "invisible" are small: length - 14.2 m, wingspan - 9.1 m, height along the rear stabilizers - 4.5 m. There is room for one crew member.

Based on the small size of the airframe and the widest use of composite materials, and this is more than 30% plastic with reinforcing carbon, 2 lightweight XF5-1 turbofan engines with a thrust of about 5500 kg / s each, the mass of an empty fighter will be in the range of 6.5-7 tons, t .e. weight and overall dimensions will be very close to the French fighter Mirage-2000-5.

Due to the miniature midsection and the maximum slope of the air intakes to the longitudinal axis of the aircraft (better than that), as well as the minimum number of right angles in the design of a sophisticated airframe, the Shinsina EPR should meet the expectations of the Japanese military flight crew, and not exceed 0.03 m 2 ( F-22A has about 0.1 m 2, T-50 has about 0.25 m 2). Although, according to the developers, the equivalent of a “small bird” sounded, and this is 0.007 m 2.

Shinsina engines are equipped with an all-aspect OVT system, consisting of three controlled aerodynamic petals that look very “oak”, like for a 5+ generation fighter, but apparently Japanese engineers saw in such a design some guarantees of greater reliability than our “all-aspect” on the product 117C. But in any case, this nozzle is better than the American one, set to , where the vector control is performed only in pitch.

The avionics architecture is planned to be built around the powerful J-APG-2 airborne radar with AFAR, the detection range of the F-16C type target will be about 180 km, close to the Zhuk-A and AN / APG-80 radars, and a multi-channel data bus based on fiber-optic conductors, controlled by the most powerful on-board computers. In the context of the progress of Japanese electronics, this can be seen firsthand.

The armament will be very diverse, with placement in the internal compartments of the fighter. With OVT, the aircraft partially realizes super-maneuverable qualities, but due to the smaller ratio of the wingspan to the length of the fuselage than other aircraft (for the Sinsin - 0.62, for the PAK-FA - 0.75), a glider with an aerodynamic bearing structure, as well as developed forward influxes at the wing roots, the absence of a statically unstable scheme in the airframe, there is no possibility of an emergency transition to high-speed unsteady flight. In BVB, this aircraft is more inherent in medium-speed "energy" maneuvering using OVT.

Previously, the Land of the Rising Sun wanted to conclude a contract with the United States for the purchase of several dozen Raptors, but the American military leadership, with its unequivocal position of complete non-proliferation in the field of "precise" defense, refused to provide the Japanese side with even a "depleted version" of the F-22A.

Then, when Japan began testing the first ATD-X layout, and asked for a special wide-range electromagnetic StingRay test site for all-angle scanning of the EPR index, they again “wiped their feet” on their Pacific partner. The French side agreed to provide the installation, and things went further ... Well, let's see how the sixth fifth-generation fighter will surprise us at the end of the year.

As of early 2012, the strength of the Japan Air Self-Defense Force was about 43,700. The aircraft fleet includes about 700 aircraft and helicopters of the main types, of which the number of tactical and multi-role fighters is about 260 units, light training / attack aircraft - about 200, AWACS aircraft - 17, electronic intelligence and electronic warfare aircraft - 7, strategic tankers - 4 , military transport aircraft - 44.

The F-2 was intended primarily to replace the third-generation Mitsubishi F-1 fighter-bomber - according to experts, an unsuccessful variation on the SEPECAT "Jaguar" theme with insufficient range and low combat load. The appearance of the F-2 aircraft was significantly influenced by the American project General Dynamic "Agile Falcon" - a slightly enlarged and more maneuverable version of the F-16 "fighting Falcon" Although outwardly the Japanese aircraft is very similar to the American counterpart, it should still be considered a new aircraft that differs from prototype not only by differences in the design of the airframe, but also by the structural materials used, on-board systems, electronics and weapons. Compared with the American machine in design Japanese fighter promising composite materials were used much more widely, which ensured a decrease in the relative mass of the airframe. In general, the design of the Japanese aircraft is simpler, lighter and more technologically advanced than that of the F-16.

Formation of current Japanese Air Force began with the adoption on July 1, 1954, of a law establishing the Directorate of National Defense, as well as land, naval and air force. Problem aviation technology and personnel was solved with American help. In April 1956, an agreement was signed to supply Japan with F-104 Starfighter jet aircraft.

At that time, this multi-role fighter was undergoing flight tests, showing high capabilities as an air defense fighter, which corresponded to the views of the country's leadership on the use of the armed forces "only in the interests of defense."
Subsequently, when creating and developing the armed forces, the leadership of Japan proceeded from the need to ensure the "primary defense of the country against aggression." The subsequent response to a possible aggressor under the security treaty was to be given by the US armed forces. Tokyo considered the deployment of American military bases on the Japanese islands as a guarantor of such a response, while Japan assumed many of the costs of ensuring the life of the Pentagon facilities.
Based on the foregoing, the equipment of the Japanese Air Force began.
"Starfighter" in the late 1950s, despite the high accident rate, became one of the main fighters of the Air Force of many countries, was produced in various modifications, including in Japan. It was an all-weather F-104J interceptor. Since 1961, the Air Force of the Land of the Rising Sun has received 210 Starfighter aircraft, 178 of which were produced by the well-known Japanese concern Mitsubishi under license.
I must say that the construction of jet fighters in Japan was launched back in 1957, when the production (also under license) of the American F-86F Saber aircraft began.

F-86F "Saber" of the Japan Air Self-Defense Force

But by the mid-1960s, the F-104J began to be regarded as an obsolete machine. Therefore, in January 1969, the Japanese Cabinet of Ministers decided to equip the country's Air Force with new fighter-interceptors. The American F-4E "Phantom" third-generation multirole fighter was chosen as the prototype. But the Japanese, when ordering the F-4EJ variant, made it a condition that it was an interceptor aircraft. The Americans did not object, and all equipment for working on ground targets was removed from the F-4EJ, but the air-to-air armament was strengthened. All in accordance with the Japanese concept of "only in the interests of defense." The leadership of Japan demonstrated, at least in concept documents, the desire to ensure that the country's armed forces remain national armed forces and ensure the security of their territory.

A "softening" of Tokyo's approaches to offensive types of weapons, including in the Air Force, began to be observed in the second half of the 1970s under pressure from Washington, especially after the adoption in 1978 of the so-called "Guidelines for Japan-US Defense Cooperation." Prior to this, no joint actions, even exercises, of self-defense forces and American units were conducted on the territory of Japan. Since then, much, including in the performance characteristics of aviation equipment, in the Japanese Self-Defense Forces has been changing based on joint actions. On the still produced F-4EJ, for example, equipment for aerial refueling is installed. The last Phantom for the Japanese Air Force arrived in 1981. But already in 1984, a program was adopted to extend their service life. At the same time, the Phantoms began to be equipped with bombing equipment. These aircraft were named Kai.
But this does not mean that the main task of the Japanese Air Force has been changed. It remained the same - ensuring the country's air defense. That is why, since 1982, the Japanese Air Force began to receive license-produced all-weather F-15J interceptor fighters. It was a modification of the American all-weather tactical fighter fourth generation F-15 "Eagle", designed "to gain air superiority." To this day, the F-15J is the main air defense fighter of the Japanese Air Force (in total, 223 such aircraft were delivered to them).
As you can see, almost always the emphasis in the choice of aviation equipment was placed on fighters aimed at air defense tasks, at gaining air superiority. This applies to the F-104J, and F-4EJ, and F-15J.
It was only in the second half of the 1980s that Washington and Tokyo agreed to jointly develop a close support fighter.
The validity of these statements has so far been confirmed in the course of collisions due to the need to re-equip the fleet of fighters military aviation countries. The main task The Japanese Air Force remains to provide air defense countries. Although the task of providing aviation support was added ground forces and the Navy. This is evident from organizational structure Air Force. It has three aviation directions - Northern, Central and Western. Each of them has two fighter aviation wings, including two squadrons. At the same time, out of 12 squadrons - nine air defense and three tactical fighter. In addition, there is the South-Western Composite Aviation Wing, which includes another air defense fighter aviation squadron. Air defense squadrons are armed with F-15J, F-4EJ Kai aircraft.
As you can see, the core of the "base forces" of the Japanese Air Force are interceptor fighters. There are only three direct support squadrons and they are armed with F-2 fighters of joint Japanese-American development.
The current program of the Japanese government to re-equip the aircraft fleet of the country's Air Force is generally aimed at replacing obsolete Phantoms. Two options were considered. According to the first variant of the tender for a new F-X fighter it was supposed to purchase from 20 to 60 fifth-generation air defense fighters similar in terms of performance characteristics to the American F-22 Raptor fighter (Predator, manufactured by Lockheed Martin / Boeing). It entered service with the US Air Force in December 2005.
According to Japanese experts, the F-22 is the most consistent with Japan's defense concepts. The American F-35 fighter was also considered as a backup option, but it is believed that more aircraft of this type will be required. In addition, this is a multi-purpose aircraft and its main purpose is to strike targets on the ground, which does not correspond to the concept of "only in the interests of defense." However, the US Congress in 1998 banned the export of " latest fighter, which uses all best achievements» aviation industry U.S.A. With this in mind, most other countries buyers of American fighters are satisfied with more early models F-15 and F-16, or awaiting the start of sales of the F-35, which uses the same technologies as the F-22, but it is cheaper, more versatile in application and was intended for export from the very beginning of development.
Of the American aviation corporations, the closest ties are with the Japanese Air Force long years had a Boeing. In March, he proposed a new significantly upgraded F-15FX model. Two other Boeing-produced fighters are also being offered, but they have no chance of success, since much of these machines are outdated. What is attractive about Boeing's application for the Japanese is that the corporation officially guarantees assistance in the deployment of licensed production, and also promises to provide Japanese companies with the technologies used in the manufacture of aircraft.
But most likely, according to Japanese experts, the F-35 will become the winner in the tender. It has almost the same high performance characteristics as the F-22, belongs to the fifth generation fighter and has some features that the Predator does not have. True, the F-35 is still under development. His admission to the Japanese Air Force, according to various estimates, may begin in 2015-2016. Until then, all F-4s will have served their useful lives. The delay in the choice of a new main fighter for the country's air force is a concern in Japanese business circles, since in 2011, after the release of the last of the ordered F-2s, for the first time in post-war Japan, it was necessary, albeit temporarily, to curtail its own construction of fighters.
Now in Japan there are about 1200 companies associated with the production of fighter jets. They have special equipment and possess necessary training staff. The leadership of the Mitsubishi Jukogyo Corporation, which has the largest portfolio of orders from the Ministry of Defense, believes that "the production technologies of the defense sector, if they are not supported, are lost and never revived."

In general, the Japanese Air Force is well-equipped, sufficiently modern military equipment, which is in high combat readiness, is quite capable of solving the assigned tasks.

In service with naval aviation Naval Forces self-defense (Navy) of Japan are 116 aircraft and 107 helicopters.
Patrol air squadrons are armed with R-ZS Orion base patrol aircraft.

ASW helicopter squadrons are equipped with SH-60J and SH-60K helicopters.

Anti-submarine SH-60J Japanese Navy

Search and rescue squadrons include three search and rescue squadrons (three UH-60J helicopters each). There is a squadron of rescue seaplanes (US-1A, US-2)

US-1A seaplanes of the Japanese Navy

And two EW squadrons equipped with EP-3, UP-3D and U-36A EW aircraft, as well as reconnaissance OR-ZS.
Separate aviation squadrons, according to their purpose, solve the tasks of conducting flight tests of naval aircraft, participate in the operations of mine-sweeping forces, as well as in measures for the transfer of personnel and cargo by air.

On the Japanese islands, within the framework of a bilateral Japanese-American treaty, the 5th Air Army of the US Air Force (headquarters at Yokota Air Base) is permanently deployed, which includes 3 aviation wings equipped with the most modern combat aircraft, including 5 generations F-22 Raptor.

In addition, the US Navy's 7th Operational Fleet is constantly operating in the Western Pacific Ocean. The headquarters of the commander of the 7th Fleet is located in Yokosuka PVMB (Japan). Formations and ships of the fleet are based at Yokosuka and Sasebo WWMB, aviation - at Atsugi, Misawa air bases, formations marines- to Camp Butler (Okinawa) on the terms of a long-term lease of these bases from Japan. The forces of the fleet regularly participate in operations to ensure security in the theater of operations, in joint exercises with the Japanese Navy.

The US Navy Carrier Strike Group, which includes at least one aircraft carrier, is almost constantly located in the region.

Near Japanese islands a very powerful aviation group is concentrated, several times superior to our forces in this region.
For comparison, the combat aviation of our country on Far East as part of the Air Force and Air Defense Command, the former 11th Army of the Air Force and Air Defense - operational association of the air force Russian Federation, with headquarters in Khabarovsk. It has no more than 350 combat aircraft, most of which are not combat-ready.
In terms of numbers, the naval aviation of the Pacific Fleet is approximately three times inferior to the aviation of the Japanese Navy.
