Another F-15J accident

Citation :: F-15 part falls off during training drill

Kyodo

The Air Self-Defense Force said a tail part from an F-15 fighter fell off during a training flight Friday near the Hyakuri Air Base in Ibaraki Prefecture, but there have been no reports of it causing any damage.

A search around the base failed to find the missing part, the ASDF said Friday. The missing part weighs around 2 kg and is 25 cm long and 5 cm in diameter. It was attached to the edge of one of the vertical fins as a weight to suppress vibrations on its right side.

The fighter left the base at around 12:40 p.m. Friday for an exercise over the Pacific. The part was found missing during an inspection after the plane returned to the base around 1:30 p.m.

Citation :: Le Japon lance un satellite-espion (JAXA)

Le Japon a lancé avec succès un satellite-espion Radar-3 depuis le cosmodrome de Tanegashima, a annoncé lundi l'agence aérospatiale japonaise JAXA.

Le satellite Radar-3 est destiné à recueillir des informations sur la Corée du Nord. En septembre dernier, le Japon a déjà lancé un satellite de reconnaissance optique Kogaku-4, équipé de caméras télescopiques de grande résolution capables de discerner un objet de 60 cm. Avec la mise en orbite du Radar-3, le Japon sera capable d'obtenir des images y compris la nuit et à travers des nuages très épais.

Les deux satellites ont été construits par Mitsubishi Heavy Industries.

Selon les médias japonais, la mise au point du satellite Radar-3 a coûté près de 517 millions de dollars et son lancement - 133 millions de dollars.

Citation :: Reports: Japan likely to buy US F-35 fighters

TOKYO — Japan's government has selected the Lockheed Martin F-35 stealth fighter to bolster its aging air force and is likely to announce the multibillion-dollar deal by the end of the week, news reports said Tuesday.

The announcement is expected after a committee meeting Friday, according to Kyodo News agency and the Yomiuri newspaper. A spokesman for Lockheed Martin said it had not been informed of any decision and, pending the formal announcement, officials refused to comment on which plane was favored.

"We would like to announce our decision as soon as possible," Defense Minister Yasuo Ichikawa said in response to the reports. He said the government is in the "final stages" of reaching a conclusion.

Japan is expected to buy 40 to 50 jets for as much as $8 billion, though the value of the deal depends on what package Japan chooses. The Yomiuri report said Japan will budget for the first four aircraft in 2012, with deliveries starting in 2016.

Japan's decision will have deep ramifications for Asian security and may provide a tail wind for U.S. fighter sales around the world, said Takehiko Yamamoto, a professor of international relations at Tokyo's Waseda University.

He noted that Lockheed Martin is pushing the F-35 strongly abroad and a thumbs-up from Tokyo would mark a major success.

"This deal is very important to them," he said. "Choosing the F-35 would also be a strong statement by Japan that it is committed to its national security."

Dave Scott, director of Lockheed Martin's F-35 international business development, said Japan's decision will be "a very visible one around the globe."

Japan has wrangled for years over whether to buy the F-35, Boeing F-18 or the Eurofighter Typhoon, made by a consortium of European companies. The U.S. planes were seen as the favorites because of close U.S.-Japan military ties.

The F-35, also called the Joint Strike Fighter, is the Pentagon's biggest weapons procurement program — costing $238 billion — and has support from allies including Britain, Australia, Canada, Israel and several European nations. It is to be used by the U.S. Air Force, Marines and Navy.

Though the program has been criticized for cost overruns and delays, Lockheed says that eventually several thousand could be produced.

Japan — with 362 fighter jets, mostly F-15s, F-4s and F-2s — is already one of the top air powers in the region. But planners have long been concerned by the increasing age and expense of maintaining the fleet — along with Japan's ability to match the improving air capabilities of its neighbors.

To further sweeten the deal, Lockheed has promised Japan a share of the assembly and production of the aircraft, which is important to local producers. Once it gets involved in the program, Japan could also benefit as an exporter of F-35 components, although that would require the easing of its weapons trade restrictions.

The new fighters would replace the F-4s.

Washington is Tokyo's main ally. Roughly 50,000 U.S. troops are stationed in Japan under a security pact. Japan's air force must work closely with its American counterpart, and using the same or similar equipment makes that easier.

Japan's main concerns are China and Russia — with which it has long-standing territorial disputes — along with the threat of North Korean ballistic missiles.

China, whose military has been growing more capable and assertive, recently rolled out its next-generation stealth fighter, the much-touted Chengdu J-20. Though it may be years away from actual operations, it is seen as a rival to the best U.S. fighters and far superior to what Japan now has

TOKYO | Tue Dec 20, 2011 1:06am EST

TOKYO (Reuters) - Japan picked Lockheed Martin's F-35 jet as its next mainstay fighter Tuesday, choosing the aircraft over combat-proven but less stealthy rivals, as concern simmers over North Korea and as China introduces its own stealth fighters.

The decision came as Japan and the United States stressed that their security alliance was tight in the face of worry about an unstable North Korea after the death of its leader, Kim Jong-il.

Defense Minister Yasuo Ichikawa said the decision to buy 42 of the stealth aircraft, valued by analysts at more than $7 billion, would help Japan adjust to a changing security environment after Monday's announcement of the death of the 69-year-old North Korean leader.

"The security environment surrounding future fighter jets is transforming. The F-35 has capabilities that can firmly respond to the changes," Ichikawa told reporters.

Lockheed Martin and the Pentagon hailed Japan's selection of the F-35, saying it would help establish a strategic, conventional deterrent in the Asia-Pacific region, where concern simmers about instability under Kim's successor, his untested youngest son, Kim Jong-un.

"The F-35 Program Office looks forward to strengthening partnerships with Japan, and contributing to enhanced security throughout the Asia Pacific region," the Pentagon said in a statement after Japan announced its decision.

The F-35, which is in an early production stage, competed against Boeing's F/A-18 and the Eurofighter Typhoon, made by a consortium of European companies including BAE Systems.

Experts said the decision to opt for the U.S. plane, made informally well before news of Kim's death, reflected Japan's desire to tighten U.S. ties in the face of concern over China's rising military might and other regional uncertainties.

"It reflects Japan's recognition on a variety of levels that at a time of greater insecurity, it needs to be more deeply engaged with the United States on security issues," said Brad Glosserman, executive director at Honolulu's Pacific Forum CSIS.

In a sign the allies meant to stand together, U.S. President Barack Obama spoke by telephone to Japanese Prime Minister Yoshihiko Noda and underscored the U.S. commitment to its allies, the White House said.

Japanese Chief Cabinet Secretary Osamu Fujimura told a news conference that Washington and its two close Asia allies, Japan and South Korea, were likely to hold high-level talks on North Korea soon. "The date has not been decided but it will be at the soonest possible opportunity," he said.

U.S.-Japan relations had frayed after the novice Democratic Party of Japan took power in 2009 for the first time, vowing to recalibrate the alliance on a more equal basis and attempting, unsuccessfully, to keep a pledge to move a U.S. military base off Japan's Okinawa island.

Noda, who took office last September, has firmly shifted gears back to a more traditional security stance.

"Once again, Japan's security policy is right back to the post-war Japanese mainstream -- the decision that the U.S. is Japan's best security partner," Glosserman said.

Japan had been widely expected to choose the F-35 due to its advanced stealth capability and U.S. origin. Stealth technology has drawn much attention in Japan since China, which has a long-running territorial dispute with Japan, in January confirmed it had held its first test flight of the J-20 stealth fighter jet.

Despite Sino-Japanese tension over territorial feuds, maritime resources and a bitter wartime past, Noda will nonetheless be seeking China's cooperation in coping with North Korea when he visits Beijing on December 25-26.

"Instructions from the prime minister were that we need to establish close cooperation and exchange of information with the United States, South Korea and China, so we will seek to work with China on this understanding," Fujimura said.

BOOST FOR LOCKHEED MARTIN

Japan's choice of the F-35 comes as a shot in the arm for Lockheed Martin's F-35 program, which has been restructured twice in the past two years and is expected to boost the odds that South Korea will follow suit with its own order for 60 fighters. Japan will pay 9.9 billion yen per fighter including backup parts in the initial stage of procurement.

"This program badly needed an endorsement like this, particularly one from a technically respected customer. But there are still many complications, especially price tag and work share demands," said Richard Aboulafia, an analyst with the U.S.-based Teal Group.

He said the F-35 program was facing scrutiny from U.S. lawmakers and officials who need to trim hundreds of billions of dollars from the defense budget over the next decade.

Boeing's loss of the order would be a real setback for the company's prospects in the fighter business, especially since there were few other large competitions open anymore, said Loren Thompson of Lexington Institute.

"The market place is signaling to Boeing that its days in the fighter business may be numbered," Thompson said.

Japanese firms Mitsubishi Heavy Industries Ltd , IHI Corp and Mitsubishi Electric Corp will participate in the production and maintenance of the F-35, the Defense Ministry said.

A Lockheed Martin official said Japanese defense contractors could become global suppliers to the F-35 stealth fighter program if Japan's government decided to ease a decades-old ban on exports of military equipment.

"The Japanese aerospace industry is world class, so if there was a relaxation (of the export ban) it would be very logical for them to have the opportunity and indeed it would be a very good opportunity to participate in the F35 global supply chain," Dave Scott, director of international business development for the stealth fighter, told Reuters.

Japan is considering easing the export ban, a step that might allow its contractors to bid for contracts in the United States, which spends 10 times as much on its military.

Ending the ban would also allow Japan to buy aircraft, ships, missiles and other equipment more cheaply by allowing domestic manufacturers to tap overseas markets and lower production costs through economies of scale.

Citation :: Japan looks to relax arms export ban

Japanese Defense Minister Yasuo Ichikawa said on Saturday his government intends to ease arms export restrictions, Kyodo News reported.

''In the past, we have made exceptions, but we would like [now] to create a framework based on new guidelines,'' Ichikawa said.

The government seeks to relax the ban to allow Japanese firms to participate arms development and production projects with other countries.

The move is designed to revitalize the domestic defense industry and cut defense spending.

The restrictions, introduced in 1967, ban arms sales to communist states, countries under UN embargos, and countries involved in international conflicts.

Citation :: Japan Judged F-35 To Have Best Performance

The Japanese defense ministry says the Lockheed Martin F-35A Lightning’s performance beat that of the other two contenders in the competition for Japan’s F-X fighter requirement.

The ministry says the F-35A also was the cheapest, because the competing Eurofighter Typhoon and Boeing F/A-18E/F Super Hornet would have needed modification for flying-boom inflight refueling.

Japanese industry will be able to make 40% of the aircraft’s “300 components,” according to a Sankei newspaper report that does not say how the parts have been counted. The Yomiuri newspaper says the U.S. government is proposing that Japan build F-35 wings and tails, work that would otherwise go to Lockheed Martin and BAE Systems, respectively.

These reports indicate that Japan will, as expected, retreat from its previous policy of near-complete manufacturing of fighters. But it will retain considerable industrial capabilities, at least in structures. Lockheed Martin is also suggesting that Japan build a final assembly plant, which it is likely to do.

The larger the local industrial involvement in building Japanese F-35s, the greater the likelihood that the country will keep building them after the initial requirement for 42 is filled. Although recent news reports say Japan needs 40-50 F-35s, the defense ministry confirms it will buy 42, the number that industry executives had been expecting. Before the F-X selection was made, Japanese manufacturers urged that the aircraft be built in-country until the late 2020s to replace some of its Boeing F-15Js.

The defense ministry says it gave each contender a score in four areas. A maximum of 50 points was available for aircraft performance, 22.5 for cost, 22.5 for domestic industrial participation and 5 for after-sales support.

It does not explain why the F-35 led in the assessment of performance, except that the result was based on operations research, but the defense ministry adds that it was also judged as having the best after-sales support. The stealth fighter appears to have lagged on domestic industrial participation — because the U.S. government is not expected to allow enough technology transfer to build all of it. Eurofighter agreed to 95% “information-sharing” and Boeing to 70-80%, the Sankei says, without explanation. The information-sharing offer for the F-35 was extremely low by comparison, the paper says.

Eurofighter officials had previously said Japan could build as much of the Typhoon as they wanted. Eurofighter’s offer particularly appealed to some members of the Diet, according to a newspaper from the Nagoya area, where Mitsubishi Heavy Industries has its aerospace works. Several of them argued in a meeting of the Diet defense committee that Japan should choose the Typhoon for the F-X requirement, to replace F-4EJ Kai Phantoms, and then switch to the F-35.

The defense ministry makes no mention of assigning a value to the risk of buying each aircraft, as its counterparts in other countries often do, especially when considering an order for equipment that is still under development. After repeated delays, the F-35 is now due to achieve initial operational capability with the U.S. Air Force in 2018, with its F-35A version.

The first four F-35As for Japan are to be ordered in the fiscal year that begins on April 1, 2012, for delivery in 2016. The defense ministry expects them to cost ¥9.9 billion ($127 million) each, not including the cost of running them. That leaves a lot of room for savings when compared with the ¥15 billion unit cost that Defense Minister Yasuo Ichikawa cited in November for further production of the Mitsubishi Heavy Industries F-2 strike fighter.

The defense ministry projects that Japan will spend ¥1.6 trillion in buying all 42 F-35As and operating them for 20 years.

Citation :: Japan Orders Northrop Grumman's Airborne Laser Mine Detection Systems

Northrop Grumman Closes First International Sale of Airborne Capability

16:18 GMT, February 3, 2012 TOKYO and MELBOURNE, Fla. | The Japan Maritime Self-Defense Force has purchased four helicopter-mountable, laser mine detection systems to help protect its coastline and the daily maritime traffic coming in and out of the country's ports. This is the first direct commercial sale of Northrop Grumman Corporation's Airborne Laser Mine Detection System (ALMDS) to an international navy.

"ALMDS will enable the Japan Maritime Self-Defense Force to cover significant distances at the speed of flight using its MCH-101 aircraft. This technology dramatically compresses the time between mine detection and neutralization," said Donna Carson-Jelley, ALMDS program manager for the U.S. Navy. "ALMDS keeps mine countermeasures ahead of the threats."

The mine detection system is laser-based and utilizes streak tube imaging light detection and ranging (LIDAR) to detect, classify and localize near-surface moored sea mines. With high area coverage rate capability, the system transmits a fan-shaped beam of laser light to establish its swath width, and then relies on the forward motion of the helicopter to sweep the light over the water in a "push broom" manner.

Four cameras are arranged to cover the same swath illuminated by the laser fan beam. As images are received by the system, an automatic target recognition algorithm picks out potential mine-like objects and stores their images for classification by shipboard Fleet operators, using computer-aided post-mission analysis tools.

"The addition of ALMDS to the Japan Maritime Self-Defense Force mine countermeasures suite of solutions provides them with significantly enhanced mine detection capability—first developed for the United States Navy," said Pat McMahon, sector vice president and general manager, Military Aircraft Systems of Northrop Grumman Aerospace Systems. "The installation of this capability will also improve the exchange of information between the U.S. Navy and JMSDF during allied operations."

Northrop Grumman is working closely with its industry partners Kawasaki Heavy Industries, Ltd., and Fujitsu Limited on the delivery and installation of ALMDS.

"The addition of our mine countermeasures systems broadens the strong relationship we have with the Japan Ministry of Defense and we are very proud of that partnership. It goes back to the early 1960s," said McMahon. The Japan Air Self-Defense Force has flown the Northrop Grumman-built E-2C Hawkeye airborne early warning command and control system since 1982.

Japan lays keel for 22DDH Helicopter Carrier

A keel-laying ceremony for the first 22DDH helicopter carrier for the Japan Maritime Self-Defence Force (JMSDF) was held at IHI Marine United's (IHIMU's) Yokohama on 27 January 2012. Japan already has two helicopter carriers -- the Hyuga deployed in March 2009 and the Ise deployed in March 2011 -- but the new vessel will be larger.

The 22DDH is scheduled for deployment in 2015. It will be 248 m long and cost around US$1.04 billion. It is 30 percent bigger than the Ise and can carry 14 helicopters. The Ise measures 197 m, has a displacement of 13,500 tons and can carry 11 helicopters.

Akizuki : Les nouveaux destroyers japonais

Armée Japonaise/Japan Self-Defense Forces - Page 10 41185

L'Akizuki, premier de la série des destroyers du type 19DD
crédits : JMSDF

15/02/2012

La marine japonaise se dote d'une nouvelle classe de destroyers. Il s'agit du type 19DD. Lancée en octobre 2010 aux chantiers Mitsubishi Heavy Industries de Nagasaki, la tête de série, l'Akizuki, sera opérationnelle en mars, alors que ses trois sisterships en sont à différents stades de construction et d'essais. Mis à flot en septembre dernier, le Teruzuki, doit entrer en service en mars 2013 et les deux suivants en 2014. Longs de 150 mètres pour une largeur de 17.6 mètres, les bâtiments du type 19DD affichent un déplacement de 6800 tonnes en charge. Leur armement comprend 8 missiles antinavire SSM-1B (d'une portée de 150 kilomètres), 32 cellules de lancement vertical pour missiles surface-air ESSM et anti-sous-marins Asroc, une tourelle de 127mm, deux systèmes multitubes Phalanx et six tubes lance-torpilles. Ils peuvent, en outre, embarquer un hélicoptère Seahawk. La propulsion est assurée par quatre turbines à gaz SM1C Spey (Rolls-Royce) ce qui assure une vitesse maximale de 30 noeuds. L'équipement électronique comprend, notamment, un radar de veille à quatre faces planes FCS-3A.
Les Akizuki sont plutôt spécialisés dans la lutte anti-sous-marine et permettent aux forces navales japonaises de commencer à remplacer les 12 destroyers de la classe Hatsuyuki, mis en service entre 1982 et 1987.

Citation :: Japan - KC-130R Aircraft

The Defense Security Cooperation Agency notified Congress Feb. 16 of a possible Foreign Military Sale to Japan to provide regeneration, overhaul, modifications and support for 6 KC-130R aircraft and associated engines for an estimated cost of $170 million.

The Government of Japan has requested a possible sale to provide 6 KC-130R and 30 T-56-A-16 engines being provided as Excess Defense Articles (EDA), along with the regeneration, overhaul, modifications, and logistics support for those engines. Also included are 6 non-EDA spare T-56-A-16 engines, 6 AN/APS-133 Radars, 9 AN/APX-119 Transponder Systems (6 installed and 3 spares), transportation, aircraft ferry support, repair and return, spare and repair parts, support equipment, tools and test equipment, technical data and publications, personnel training and training equipment, U.S. Government and contractor engineering, technical, and logistics support services, and other related elements of logistics support. The estimated cost is $170 million. The EDA portion of this sale is also being notified separately as required by statute.

Japan is one of the major political and economic powers in East Asia and the Western Pacific and a key ally of the United States in ensuring the peace and stability of this region. The U.S. Government shares bases and facilities in Japan. This proposed sale is consistent with these U.S. objectives and with the 1960 Treaty of Mutual Cooperation and Security.

The proposed sale of aircraft and support will help to modernize the Japanese Defense Force’s aging cargo aircraft fleet. The KC-130 will provide Japan with an improved capability for the movement of cargo and personnel in humanitarian missions.

The proposed sale of this equipment and support will not alter the basic military balance in the region.

Les japonais intègrent le missile air-air AAM-4B sur une soixantaine de F-2.

Citation :: Japan's Air-to-Air Upgrade

Japan already has bought Raytheon AIM-120 Amraams, so why is it spending ¥36 billion ($468 million) to upgrade about 60 F-2 fighters with the Mitsubishi Electric Corp. AAM-4B missile?

Although the benefits to Japanese industry are obvious, details of the upgrade and the missile itself suggest that the program is giving an enormous boost to the Mitsubishi Heavy Industries fighter’s ability to counter enemy aircraft. The weapon has at least one advanced feature that other such missiles lack: a seeker with an active, electronically scanned array (AESA) radar.

The program will move into high gear in the financial year that begins April 1. The work is progressing in two parallel programs: integration of the AAM-4B missile, and upgrade of the J/APG-1 radar to a more powerful standard called J/APG-2. The improved radar, needed to exploit the new missile, will incidentally raise the capabilities of the aircraft by offering greater detection ranges.

Both systems have been developed by the Japanese defense ministry’s Technical Research and Development Institute with considerable help from contractors, Mitsubishi Heavy Industries for the missile integration and Mitsubishi Electric for the radar. The same companies are contracted to do the installation work. Ministry officials tell Aviation Week that development went smoothly and is now complete.

Early in the development program, in 2001, the ministry gave rough indications of the AAM-4B’s capabilities. It could be launched at a 20% greater range than could the then-current AAM-4 and at least as far as an “AIM-120B+,” a standard that was expected to appear around 2004. The crucial claim was that the AAM-4B could switch to autonomous guidance at a 40% greater range than either of the other two missiles and would similarly outperform what was expected to be the 2009 standard of the Russian R-77 (AA-12 Adder). In a 2010 paper, the ministry attributed the seeker’s greater performance to the higher transmitting power available from the AESA.

The implication is that an F-2 firing AAM-4Bs can stop tracking the target for missile guidance much sooner than an unmodified F-2 can—and officials tell Aviation Week that the key aim of the project is indeed to increase the range at which an F-2 can turn away.

Referring to this detail, a former high-ranking U.S. Air Force officer says: “In the air-to-air realm, a 40% increase in range is very significant and would provide the [Japan Air Self-Defense Force] a very capable missile.” The same person, highly familiar with the electronic technology of air warfare, does not regard the advances claimed for the upgraded F-2 as improbable; they are to be expected, he says.

The ministry also says that the AESA seeker will have a better capability against a crossing target—one that reflects a radio signal with the same frequency as the ground. Fighter pilots can dive and turn at right angles to a threat to create that complication for enemy radars and missiles.

The number of F-2s that are already able to use the AAM-4B is undisclosed, but a budget allocation to do most of the radar upgrades in fiscal 2012 shows that the bulk of the installation program is only now getting underway. The missile integration, centered on an upgrade of the fire-control system, will be applied to 16 aircraft in that fiscal year, at a cost of ¥340 million per aircraft, while 40 will get the new radar, for ¥260 million each. Future budgets will determine when the planned 60 upgrades, enough to equip three squadrons, are completed. The work is being done in conjunction with heavy maintenance on each fighter.

Research and development of the F-2’s fire-control upgrade began in 2004. The installation was mentioned in the fiscal 2010 budget, but little has been known about it. The ministry is always secretive about its air-to-air missiles.

Citation :: Japan's Ministry of Defense to acquire a Eurocopter EC225 for passenger transportation

Tokyo, 14 March 2012

Eurocopter Japan, a subsidiary of Eurocopter Group, will supply one EC225 to the Japan Ministry of Defense, to be operated by the Japanese ground self defense force for passenger transport. It is a replacement for the same helicopter model which was submerged during the earthquake and tsunami that hit Japan in March last year.

The Japan Ministry of Defense signed a contract on 8th March 2012 with Eurocopter to acquire an EC225, a heavy twin-engine helicopter from Eurocopter’s Super Puma family. It had a fleet of three EC225s, but one of which was submerged during the Great East Japan Earthquake and Tsunami. The procurement of the new 11-ton helicopter is meant as a replacement for the damaged aircraft.

Offering high cruise speed, long range coverage and high level of comfort thanks to the spacious cabin and low vibration, this aircraft is popularly used for passenger transportation and search and rescue missions all over the world.

Since the major earthquake and tsunami that struck Japan on 11th March last year, various public sectors in Japan have been boosting their rotary-wing aircraft fleet, seeing the benefits of helicopters in times of large-scale disasters. Besides being able to carry out relief efforts safely and efficiently, helicopters also proved to be the fastest and safest mode of transport, as public transportation systems were badly affected.

“The strength of the EC225 was clearly demonstrated during the disaster relief efforts, which was very much appreciated by our customers,” said Stephane Ginoux, President & CEO of Eurocopter Japan. Recent procurements of this model by the Japan Coast Guard, Tokyo Fire Department, and now the Ministry of Defense, have given great recognition to the capability of the EC225. Eurocopter Japan will also continue to provide efficient services to ensure undisrupted operations for our customers.”

The EC225 for the Ministry of Defense will be delivered in February 2015.

Citation :: Japan Making Its F-2 Fighter Fleet More Lethal

In a move destined to give Japanese defense manufacturers hope for the future, Aviation Week reported in late February that Japan plans to upgrade 60 F-2 fighters with Mitsubishi Electric Corporation’s AAM-4B missile, a $468 million deal. This enhancement is expected to dramatically improve the lethality of the F-2 when engaging enemy aircraft.

A number of Japan’s Boeing F-15J fighter aircraft were equipped with AAM-4 missiles in 2007. This version of the missile featured an advanced active radar seeker and integrated data link that allowed the pilot to fire and guide the missile to the target until the missile seeker took over allowing the aircraft to begin evasive maneuvers much earlier than in the past.

This deal will go far in helping Japan’s struggling aviation/military industry to continue operating in an environment of intense competition from international rivals.

The AAM-4B is fitted with a missile seeker featuring Active Electronically-Scanned Array (AESA) radar and a greatly improved data link. The AAM-4B will be coupled with enhanced J/APG-2 radar that gives pilots a detection range far superior to what they have now. Analysts believe that the AAM-4B will be deployed as a replacement for the Mitsubishi Electric license- built AIM-7F/M Sparrow’s now in service, a missile that was still in production as late as 2010.

With the AAM-4B’s active search capability, coupled to an upgraded J/APG-2 radar system, modified F-2’s are expected to be able to engage multiple airborne targets from medium range without having to close to visual range, greatly improving the aircraft’s survivability and deadliness.

The AAM-4B is reported to be the same size as the AIM-7F/M Sparrow missile, but its AESA radar seeker head will provide an active homing capability and after launch target lock affording pilots the flexibility to begin evasive maneuvers or focus on other threats sooner than is now possible.

By incorporating AESA capabilities into the AAM-4B, it seems possible that Japan has designed a uniquely capable air-to-air missile. While most front-line fighters of today are outfitted with AESA, no known air-to-air missiles are similarly equipped.

In the 1980s, Japan began development work on the AAM-4, partly as a means of bolstering Japan’s domestic arm’s manufacturers and to expand the nation’s missile technology capability. It is not known if the early AAM-4’s ever entered active service.

In the early stages of planning and development, Japan’s Defense Ministry’s Technical Research and Development Institute indicated that the AAM-4B could be launched from a far greater distance than the AAM-4, an increase in range of as much as 20 percent. The Institute also stated that activation of the AAM-4B’s autonomous guidance system would be possible from a range 40 percent greater than that possible with the AIM-120B AMRAAM. Also, the AAM-4B was reportedly designed to match or outperform the Russian AA-12 Adder. The enhanced performance of the AAM-4B is claimed to be partly the result of an increase in the level of power transmission incorporated in the AESA.

It is expected that a modified F-2 launching AAM-4Bs would be able to discontinue tracking a target much earlier and from a greater distance than can be achieved with an unmodified F-2. With the missile’s improved autonomous guidance system giving the aircraft extended firing range, the pilot will be able to target, fire, and execute evasive maneuvers sooner than is now possible. The upgraded AESA is also believed to improve the F-2’s ability to locate, track, and target “crossing targets,” a scenario where an air threat is flying at a right angle creating a signal of the same frequency as that of the ground.

No information has been provided to indicate how the AAM-4B compares with Raytheon’s AIM-120D AMRAAM. Some sources have expressed the opinion that the AIM-4B’s performance will hinge on the level of technology incorporated into the control and guidance systems and may not match the performance of Raytheon’s AIM-120C-7 variant, a missile that is eligible for export.

Japan also has an inventory of Raytheon AIM-120 AMRAAMS available for use. Japanese corporate heavyweights, Mitsubishi Heavy Industries and Mitsubishi Electric, also had a hand in the design and development of the AAM-4B. Mitsubishi Heavy managed the missile integration phase of the project and Mitsubishi Electric focused on upgrading the radar systems. Japan’s Ministry of Defense reported that development was completed successfully.

It is not known how many, if any, operating F-2’s are presently equipped to carry the AAM-4B, but Japan’s FY2012 budget submission does include funding for radar upgrades for 40 aircraft and fire-control upgrades for 16 aircraft. Funding for the AAM-4B enhancements for 60 aircraft is expected to appear in future budget submissions, possibly to coincide with extensive maintenance plans.

Japan’s Ministry of Defense also confirmed that the modified F-2’s will be capable of launching and coordinating several missiles aimed at more than one target simultaneously. The Ministry would not reveal the exact number of targets that may be fired upon at the same time, but the modified F-2’s will be configured to mount four AAM-4B’s.

Operational F-2’s are already equipped with AESA and the modified F-2’s will be similarly equipped. Comparable aircraft fitted with AESA employ a data link that transmits signals from the aircraft to an airborne missile using radar. The modified F-2’s will be outfitted with a separate data link transmitter, the J/ARG-1.

Additional guidance system modifications will include upgrading the existing J/APG-1 AESA radar to a J/APG-2 standard. The J/APG-2 is expected to maximize the capabilities of the AAM-4B by allowing for target detection at much longer ranges and to increase the probabilities of scoring a hit. The J/APG-2 is known to be capable of generating significantly greater power and incorporates a signal processor that is faster and more reliable. Japanese officials remain secretive regarding the specific J/APG-2 capabilities and have stated that they have not made any comparison with foreign-built radar systems. Some sources speculate that the J/APG-2 might be comparable to Raytheon’s APG-79 carried on US F/A-18E/F Super Hornets.

The upgraded F-2’s are a critical part of Japan’s air defense system and can be expected to continue in an operational flying status, alongside Japan’s existing fleet of F-15J’s, for many years to come. It is still uncertain if Japan will continue with its plans to acquire the Lockheed Martin F-35 Joint Strike Fighters or if they will select a competing aircraft to beef-up their air fleet. What is known, with production of the F-2 now completed and discontinued, is that Japan is looking at a future that is getting ever more dangerous by the day.

Citation :: Le Japon étudie la possibilité d'intercepter le satellite que la RPDC prévoit de lancer

Le ministre japonais de la Défense Naoki Tanaka a déclaré lundi qu'il étudiait la possibilité pour les Forces d'auto-défense d'intercepter le satellite que Pyongyang prévoit de lancer le mois prochain s'il passe au-dessus du Japon, ont rapporté les médias locaux.

M. Tanaka a déclaré que son ministère prendrait des mesures rigoureuses pour protéger la préfecture d'Okinawa et d'autres parties du Japon, si c'est nécessaire, a rapporté la chaîne de télévision publique NHK.

Le ministère prévoit de déployer des intercepteurs PAC-3 et des destroyers équipés du système antimissile Aegis, selon NHK.

La semaine dernière, la République populaire démocratique de Corée (RPDC) a annoncé son projet de lancement d'un satellite d'"d'observation terrestre", le Kwangmyongsong-3, au moyen d'une fusée à longue portée, à l'occasion du 100e anniversaire de son ancien dirigeant Kim Il Sung.

Le satellite sera lancé à partir d'une station dans la province de Phyongan Nord, entre le 12 et le 16 avril, selon l'agence de presse officielle KCNA, citant une porte-parole du Comité coréen pour la technologie spatiale.
