Mitsubishi F-15J
The Mitsubishi F-15J/DJ Eagle is a twin-engine, all-weather air superiority fighter based on the McDonnell Douglas F-15 Eagle in use by the Japan Air Self-Defense Force (JASDF). The F-15J was produced under license by Mitsubishi Heavy Industries. The subsequent F-15DJ and F-15J Kai variants were also produced. Japan is the largest customer of the F-15 Eagle outside the United States. In addition to combat, F-15DJ roles include training. The F-15J Kai is a modernized version of the F-15J. Development In June–July1975, the Japan Defense Agency (JDA, now Ministry of Defense) examined the McDonnell Douglas F-15 Eagle as one of the 13 candidates for the replacement of the F-104J/DJ Starfighter and F-4EJ Phantom II. A single-seat F-15C and a twin-seat F-15D were evaluated at Edwards Air Force Base, and in , the F-15 has announced the winner, with the government intending to purchase 187 F-15J/DJs. By April 1978, Mitsubishi Heavy Industries was designated as the primary contractor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japan Air Self-Defense Force
The , , also informally referred to as the Japanese Air Force, is the air and space branch of the Japan Self-Defense Forces, responsible for the defense of Japanese airspace, other air and space operations, cyberwarfare and electronic warfare. The JASDF carries out combat air patrols around Japan, while also maintaining a network of ground and air early-warning radar systems. The branch also has an aerobatic team known as Blue Impulse and has provided air transport in UN peacekeeping missions. The JASDF had an estimated 49,913 personnel as of 2018, and as of 2020 operates about 740 aircraft, approximately 330 of them being fighter aircraft. As of 2020, the JASDF is under increasing pressure to intercept warplanes from China's People's Liberation Army Air Force (PLAAF) close to entering its air space. As of the last fiscal year ending in March 2020, the JASDF scrambled a record 947 times alone against PLAAF warplanes, putting heavy wear and tear on the F-15J. As of 2021 ...

Composite Material
A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions. Typical engineered composite materials include: *Reinforced concrete and masonry *Composite wood such as plywood *Reinforced plastics, such as fibre-reinforced polymer or fiberglass *Ceramic matrix composites ( composite ceramic and metal matrices) *Metal matrix composites *and other advanced composite materials There are various reasons where new material can be favoured. Typical examples include materials which are less expensive, lighter, stronger or more durable when compared with commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney F100
The Pratt & Whitney F100 (company designation JTF22) is an afterburning turbofan engine manufactured by Pratt & Whitney that powers the F-15 Eagle and F-16 Fighting Falcon. Development In 1967, the United States Navy and United States Air Force issued a joint engine Request for Proposals (RFP) for the F-14 Tomcat and the FX, which became the parallel fighter design competition that led to the F-15 Eagle in 1970. This engine program was called the IEDP (Initial Engine Development Program) and was funded and managed out of the Aeronautical Systems Division (ASD) at Wright-Patterson AFB. Under ASD, a Systems Project Office Cadre was assigned to manage both the FX Aircraft and Engine definition phase. The Turbine Engine Division of the Air Force Propulsion Laboratory was employed in a support role to assist ASD Systems Engineering in evaluations of technical risks. Later upon selection of the F-15 the ASD engineering cadre became the F-15 Systems Project Office. The IEDP was creat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar Warning Receiver
Radar warning receiver (RWR) systems detect the radio emissions of radar systems. Their primary purpose is to issue a warning when a radar signal that might be a threat is detected, like a fighter aircraft's fire control radar. The warning can then be used, manually or automatically, to evade the detected threat. RWR systems can be installed in all kind of airborne, sea-based, and ground-based assets such as aircraft, ships, automobiles, military bases. This article is focused mainly on airborne military RWR systems; for commercial police speed detection radar RWR systems, see radar detector. Depending on the market the RWR system is designed for, it can be as simple as detecting the presence of energy in a specific radar band, such as the frequencies of known surface-to-air missile systems. Modern RWR systems are often capable of classifying the source of the radar by the signal's strength, phase and signal details. The information about the signal's strength and waveform can t ...

Electronic Countermeasure
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes using blip enhancement Blip enhancement is an electronic warfare technique used to fool radar. When the radar transmits a burst of energy some of that energy is reflected off ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

La Pérouse Strait
La Pérouse Strait (russian: пролив Лаперуза), or Sōya Strait, is a strait dividing the southern part of the Russian island of Sakhalin from the northern part of the Japanese island of Hokkaidō, and connecting the Sea of Japan on the west with the Sea of Okhotsk on the east. The strait is long and deep. The narrowest part of the strait is in the west between Russia's Cape Krillion and Japan's Cape Sōya, which is also the shallowest at only deep. A small rocky island, appropriately named Kamen Opasnosti (Russian for "Rock of Danger") is located in the Russian waters in the northeastern part of the strait, southeast of the Cape Krillion. Another small island, Bentenjima, lies near the Japanese shore of the strait. The strait is named after Jean-François de Galaup, comte de Lapérouse, who explored it in 1787. Japan's territorial waters extend to three nautical miles into La Pérouse Strait instead of the usual twelve, reportedly to allow nuclear-armed United ...

Sukhoi Su-15
The Sukhoi Su-15 (NATO reporting name: Flagon) is a twinjet supersonic interceptor aircraft developed by the Soviet Union. It entered service in 1965 and remained one of the front-line designs into the 1990s. The Su-15 was designed to replace the Sukhoi Su-11 and Sukhoi Su-9, which were becoming obsolete as NATO introduced newer and more capable strategic bombers. Development Recognizing the limitations of the earlier Su-9 and Su-11 in intercepting the new Boeing B-52 Stratofortress, particularly in terms of radar and aircraft performance, the Sukhoi OKB quickly began the development of a heavily revised and more capable aircraft. A variety of development aircraft evolved, including the Sukhoi T-49, which shared the fuselage of the Su-9 (including its single engine), but used cheek-mounted intakes to leave the nose clear for a large radome for the RP-22 Oryol-D ("Eagle") radar (NATO "Skip Spin"), and the T-5, essentially a heavily modified Su-11 with a widened rear fuselage con ...
