Armes de fabrication Israelienne - Page 20 Arie

Citation :
In the mid-70s a group of IAI (Israel Air Industries) engineers and IAF (Israeli Air Force) officers began a new project to develop an ultra modern Israeli fighter aircraft – a project that was supposed to take a quantum leap for aeronautics.

Designed to be the most advanced of its kind in the world by any standards, the Arie (Lion), would give the IAF a reliable option to the advanced US F-15 and F-16 types. Although it has never came through, the Arie became the cornerstone of another future and most ambitious project ever, an Israeli breakthrough to develop and produce the Lavi, the Israeli dream aircraft to outmatch the F-16.


Background

In response to the French embargo forced upon Israel after the Six-day warin 1967, a decision was made to strive for independence in the development of major weapons systems. Israel had already acquired the means to build good copies of the French Mirage, but wanted to be much more than just a clone maker.
The commander of the IAF (1982-1987), Gen. Amos Lapidot: said, “The essence was to create a technological infrastructure to develop and manufacture weapons systems in the three major weapons systems platforms – tanks, aircraft and ships. Behind that concept, were three basic rationales: First, Israel should not, and could not rely on foreign countries very volatile foreign policies. Secondly, the Israeli air force always strives to develop and use new war tactics and strategies, and was in constant need of new equipment to fulfill those operational objectives. Third, a national strategy to promote Israel 's and IAI's state-of-the-art technological accomplishments". This last point doesn't come over so well in English - by implication, these accomplishments would deter aggression, save money on expensive foreign weapon imports and maybe help Israeli exports.


Development

In 1974, an IAI team was set up to begin the Arie project. As no government approval had yet been received to produce it, the program was simply codenamed “R&D project”. Ovadia Harrari, who would later become head of the Lavi program, was to lead that endeavor.
The IAI decided to develop the Arie based on the technological knowhow acquired from the Kfir project, particularly from the Kfir-Canard program – the improved version. In fact, the first proposal which was put on hold by the Air Force, was to develop an aircraft to be named “Super Kfir” – a regular Kfir whose original J79 engine was replaced by an F100 model, the same as in early F-15/F-16s versions. That new engine would substantially increase the Super-Kfir's flying performance. However, due to the Air Force's strict specs requirements, a new draft was called for, in spite of the Kfir/Arie's visual similarities.
Over thirty different configurations were evaluated. The IAI tested several engine models, including the British Rolls- Royce RB-199, which powers the European Tornado aircraft. Soon, the options were reduced to just two. The F-100 single engine plane, or a twin-engine version.
The later, codenamed Light Weight Fighter-4 (LWF-4), was to be powered by two General-Electric F-404 engines as used in the F-18. “Looking at the different designs of the Arie, one can notice that it is an extensively modified Kfir” explains Harrari ,“ the aircraft is visually different, but its roots lay in the Kfir”.
The new future fighter aircraft, which was now codenamed “Hadish” (innovative), could be described as a single seat light fighter, capable of reaching 2.4 Mach speed, a 75,000 ft altitude ceiling, with a 480 km combat radius. Armament: would have been a 30-mm cannon and medium range air-to-air missiles. Avionics would include a radar, a helmet sight and an integral electronic warfare system. In addition, the aircraft would have low optical and radar signatures. Even the US F-15 and F-16 could not match these features at that time.
The outstanding question: An air-to-air fighter, or an air-to-ground attack aircraft?
During its initial design phases, the 1973Yom-Kippur war broke out, and the Israeli Air Force focused its attention on the battle proven air-to-air configuration concept, as air power and air superiority consist basically of air-to-air combat missions. Therefore, about 90 percent of the “Hadish” capabilities would be directed for air-to-air combat.


Technologies and Avionics


The Arie had several technological breakthroughs. It was designed to be the first Israeli aircraft to deploy digital fly-by-wire flight control system (at that time, cutting edge technology). This fly-by-wire concept, permitted the engineers to design an aerodynamically non-stable platform. Hence, they could achieve a small and highly maneuverable aircraft.
In the air-to-air version, to cope with enemy intruder aircraft, and keeping its air-superiority capabilities, the Arie would be equipped with advanced avionics and special ordnance systems: a highly sensitive Israeli radar capable of acquiring low-altitude flying targets. Advanced electro-optical systems would enable the Arie to locate ground targets at night.
Another breakthrough, was the pilot's option to use his helmet mounted sight, easing his combat workload. In the mid-70's these systems were nearly unheard of. It would take another ten years for the helmet mounted sight to become operational in any type of combat aircraft.
The Arie's cockpit resembles to a great extent that of the F-16's early versions. Besides the Head-up Display (HUD), a Monochromatic Display was mounted in the cockpit to display the radar's viewpoint.
The Pilot's view was close to 360º visibility– a life and death factor in air combats. This is now the normal design in both Western and Russian combat aircraft from the F-15 onwards.
The Arie's ordnance would include an improved 30-mm DAPA cannon, assorted air-to-air missiles, iron bombs, and precision guided ordnance. Max. military load is: 7 tons.
Although that aircraft was not meant to be a stealth aircraft, some basic stealth features were studied to give it the option to strike heavily fortified missile zones. This objective was based on the lessons learned during and after the 1973 Yom-Kippur war, when Israeli fighters had to face a huge number of SAMs. The Arie would also be equipped with an advanced Electronic-Warfare system produced by Israel , giving the pilot an early warning signal to lock on to enemy threats and jam them.
Studies were made to drastically reduce its radar signature, making it extremely difficult to be detected by enemy radar. For example, its bomb load was to be stowed inside a conformal ventral capsule, to reduce its radar cross section.


A Paper's Lion

According to the program timetable, the Arie's initial development phase should have been completed by mid 1979. Until then, the IAI would have to complete flight tests, select and define all the contractors.
By that year's end, an initial test flight was scheduled for the first of three prototypes.
By mid 1980, 10 pre-production aircrafts should be completed, with regular production to begin in the following two years. The Air Force should be receiving the first production Arie by the end of 1983. Delivery of 100 aircraft would be completed by the end of 1985.
Meanwhile, the IAF was leaning towards the US aircraft option. Rumors indicated that the USA would finally agree to sell Israel F-15s and F-16s. Finally, a decision was made to order the US aircraft. and scrap the Arie.
In August 1975, the IAF's chief, the (late) Gen. Benny Peled released a document defining the IAF's policy in relation to the Arie project. The document recommended the US F-15s and F-16s. Based on his assessment, the IAF began a procurement program of F-15s to be delivered by 1976. Moreover, it had been determined that the F-16 in principle answered Israel 's operational needs for an air superiority aircraft for the 80s. As a result of intense pressure on the IAF, Gen. Benny Peled decided to respond with a letter on May 10, 1976 , stating the reasons not to progress with the Arie: The US would agree to sell Israel F-16s. It had also been agreed that the US would sell Israel the F-100 engine, and there were not sufficient funds to keep the project moving.
“The fundamental knowledge that led to the development of the Lavi relied on the experience acquired from the “Hadish” and Arie”, says Gen. Lapidot, who created the Lavi project board, and commanded the Israeli Air Force by the time the project was canceled. “It can be definitely stated that the Arie, the Nesher and Kfir programs, added significantly to the development of the Israel Aircraft Industry (IAI), so that when we gave the “go ahead” for the Lavi, we already had a complete infrastructure in place and ready to work. In 1980, we decided to build a smaller version of the Arie. It is not by coincidence that it was named the Lavi. Lavi is a Lion (Arie), although a very much younger and smaller one”

IAI Elta announces multi-sensor air defence system

Yaakov Lappin, Tel Aviv - Jane's Defence Weekly

Israel Aerospace Industries (IAI) subsidiary Elta Systems unveiled on 12 June a new version of its EL/M-2084 Multi-Mission Radar (MMR) that has been developed to counter emerging threats.

Called the Multi-Sensor MMR (MS-MMR), the new system includes an additional radar and passive sensors to enable it to build a more comprehensive air situational picture (ASP).

IAI developed the MS-MMR in response to emerging aerial threats, including low radar-cross section aircraft and weapons. "This created a demand for ASP systems to provide higher accuracy, faster update rates and upgraded identification of aerial threats while increasing the need for survivability in the modern battlefield," the company said in a statement.

The MS-MMR still uses its main S-band radar to provide long-range air surveillance and fire control capabilities. This is integrated with a higher frequency radar, an active identification friend or foe (IFF) capability, an automatic dependent surveillance-broadcast (ADS-B) receiver, as well as passive electro-optical and signals intelligence (SIGINT) sensors. Passive sensors for detecting weapons being launched are also an option, according to IAI.

The higher-frequency radar is designed to provide better resolution of objects, thereby making them easier to classify. This is mounted on two panels either side of the main S-band antenna as well as another two panels that cover the rear of the radar enabling the system to detect threats approaching from directions that were previously in the EL/M-2084's blind spot.

The electro-optical sensors include infrared cameras and are designed for further investigation of targets, a function that is particularly relevant for militaries with stricter rules of engagement, while the SIGINT sensor can detect possible threats hundreds of kilometres away, according to IAI

Praetor 600 AEW aircraft



Embraer and ELTA Systems, a subsidiary of Israel Aerospace Industries (IAI), have signed a Strategic Cooperation Agreement to develop next-generation P600 AEW (Airborne Early Warning) aircraft, based on the advanced Embraer Praetor 600 business jet, at the 53rd International Paris Air Show.

The primary sensor of the P600 AEW is the IAI/ELTA 4th generation Digital Active Electronically Scanned Array (AESA) radar with integrated IFF capabilities.

In this cooperation, Embraer is to provide the air platform, ground support, communications systems and aircraft integration while ELTA is to provide the AEW radar, SIGINT (Signals Intelligence) and other electronic systems and system integration, Embraer said in a statement Tuesday.

According to the company, the P600 AEW can provide an extended Air Situational Picture by monitoring aerial activity in areas outside ground radar coverage. It can perform various missions such as Air Defense, Early Warning, Command and Control, Fighter Fleet Efficiency, Territorial Defense, and Maritime Surveillance. Also, the P600 AEW can be configured with the full range of AEW&C sensor and control systems, including; 4th generation Digital AESA AEW Radar, civil and military IFF, ESM/ELINT with Radar Warning Receiver capability, Command & Control, comprehensive communication suite including Data Networks and Satellite Links, and a robust Self Protection Suite (SPS).

A comprehensive communications suite allows for data link capability as well as satellite communication for operations beyond the line of sight data link. It also secures interoperability with allied forces. Network centric warfare (NCW) capability transforms the P600 AEW into a member of a tactical network.

An advanced self-protection system (SPS) performs the detection of potential threats activating any required electronic support measures.

The newest Arrow-3 Interceptor missile system has completed a successful flight test at Pacific Spaceport Complex-Alaska (PSCA) in Kodiak, Alaska.

“The Israel Missile Defense Organization (IMDO) of the Directorate of Defense Research and Development (DDR&D) and the U.S. Missile Defense Agency (MDA) completed a successful flight test campaign with the Arrow-3 Interceptor missile,” said in Missile Defense Agency.

Flight Test Arrow-01 demonstrated the Israeli Arrow Weapon System’s ability to conduct a high altitude hit-to-kill engagement. Interceptor tests were conducted that successfully destroyed target missiles.

The Arrow-3 Interceptor successfully demonstrated an engagement capability against the exo-atmospheric target during these tests. Although not part of the Israeli architecture, a U.S. AN-TPY2 radar participated in the test. Preliminary analysis indicates that test objectives were successfully achieved.

The Arrow Weapon System is a central part of Israel’s multi-layer defense system. The defense system is based on four operational layers: Iron Dome Defense System, David’s Sling Weapon System, the Arrow-2, and the Arrow-3.

“These successful tests mark a major milestone in the development of the Arrow Weapon System,” said MDA Director Vice Adm. Jon Hill. “This unique success in Alaska provides confidence in future Israeli capabilities to defeat the developing threats in the region. My congratulations to the Israel Missile Defense Organization, our MDA team, and our industry partners. We are committed to assisting the Government of Israel in upgrading its national missile defense capability to defend the State of Israel from emerging threats.”

IMDO Director, Moshe Patel: “Ten challenging years of development have culminated in this moment: the Arrow 3 weapon system completed a test campaign, during which an Arrow 3 interceptor completed full interception of the target. This is an extraordinary operational and technological achievement for the State of Israel, made possible by thousands of employees, engineers and officers from the Ministry of Defense, Israeli defense Industries, Israeli Air Force and our US partners. In addition, the fact that the tests were conducted in Alaska, tens of thousands of kilometers away from Israel, is another significant achievement that demonstrates the operational capabilities of the Arrow 3 system to successfully face any threat.”
