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”

Rafael eyes Litening adaptation for stealth aircraft

Rafael is considering adapting its Litening targeting pod for use on platforms like the Lockheed Martin F-35 Joint Strike Fighter, which require such equipment and weapons to be carried internally to maintain their stealth performance.

The Israeli company will not elaborate on the effort, but says it is an "expected evolution" for the proven Litening design, more than 1,400 of which have been sold by it and its US partner Northrop Grumman.

Rafael is competing on two tenders for targeting pods, which a company source says hold the potential to bring the total number of pods delivered to 2,000 "in five years from now".

Other business is coming in the form of high demand to provide upgrades for previous examples of the Litening, the source says, noting: "The system is modular, so we can upgrade it relatively easily with [new] sensors and electronics."

In 2011, Rafael confirmed it was in the advanced stages of developing a fifth-generation version of the Litening pod, with the new iteration to have features that will facilitate its installation on large unmanned air systems such as the Israel Aerospace Industries Heron TP.

The current Litening G4 includes a digital forward-looking infrared sensor and an improved TV sensor for daytime imaging, and a datalink that enables the system to receive a variety of inputs from multiple sources.

Rafael says increased demand for the Litening stems from the operational need to gain a "persistent wide-area look" on the ground, and to have the best capability to use precision-guided weapons against the right targets.

IMI offers Mars missile for multiple fighters

Israel Military Industries (IMI) has identified a variety of combat aircraft types as potential host platforms for its Mars precision-guided weapon, which is expected to offer a roughly 54nm (100km) strike range.

Suitable for use against fixed targets such as radar sites, communications centres, weapons storage facilities and airfields, plus mobile threats, the GPS-guided Mars design is 4.4m (14.4ft) long and has a launch weight of 500kg (1,100lb).



IMI's Rocket Systems Division, which has been developing the Mars system for several years, says the missile could be customised for carriage by the Boeing F-15 and F/A-18, Eurofighter Typhoon, Israel Aerospace Industries Kfir, Lockheed Martin F-16 and Sukhoi Su-24, Su-25 and Su-27/30.

IAI précise ses conditions d'exportations pour le Heron TP.

Israel defines export policy for Heron TP UAS

Israel Aerospace Industries (IAI) will have to sign joint development agreements with companies in countries that want to operate medium-altitude, long-endurance (MALE) unmanned air systems such as its Heron TP, Israeli defence ministry sources say.

The requirement stems from the fact that Israel - despite not signing the international missile technology control regime (MTCR) - complies with its guidelines.

The aim of the MTCR is to restrict the proliferation of missiles, complete rocket systems, unmanned air vehicles, and related technologies for systems capable of carrying a 500kg (1,100lb) payload at least 162nm (300km), as well as systems intended for the delivery of weapons of mass destruction.

IAI could offer the Heron TP to France and Germany, as both are partners in the MTCR, but would not be allowed to offer it to non-signatory countries.



Defence ministry sources confirm one such potential customer from a MALE UAS with capabilities similar to the Heron TP is India, but refuse to say whether there are negotiations about such a co-development agreement with New Delhi.

With a maximum take-off weight of more than 4t and a 26m (85ft) wingspan, the Heron TP is powered by a Pratt & Whitney Canada PT-6 turboprop engine.

Sources in Israel say some countries already operating Israeli-made UAS are the most likely potential customers for a jointly developed MALE UAS that will comply with the terms of the MTCR.

D'ailleurs quelqu'un sait comment se passe l'intégration d'un missile sur une plateforme étrangère ?

Est-ce que par exemple IMI va payer quelque chose pour l'intégrer sur un Su, comment ça se passe ?

normalement c´est le client qui paye l´integration specifique si le produit ne l´est pas deja par le constructeur,mais dans ce cas IMI semble vouloir faire le geste si des contrats se profilent,c´est pour ca qu´ils gagnent des marges au contraire des occidentaux qui mettent trop de conditions.

une marque de l´industrie d´armement israelienne c´est qu´elle anticipe,un produit innové se fait souvent integrer sur le maximum de plateformes retrouvés et l´offrent sur le marché avec cet argument vendeur.

les francais au contraire integrent un produit sous rafale uniquement et veulent que les autres qui le souhaitent paient l´inegration et une partie de R&D,voila pourquoi ils perdent du terrain..calculs de boutiquiers

Apparament oui,IAI propose d'installer plus de deux hose and drogue selon les besoins du client.

ce que j´ai remarqué,ca serait du new dans cette class de tanker,mais je me demande aussi si c´est assez secure pour aligner 4 Jets l´un a coté de l´autre dans une telle phase sensible que le refueling,assez delicat..

J'ai pensé a la même chose,mais après je me suis dit que l'astuce devez resider dans la longueur du tuyeau de manière a éviter de mettre cote a cote 4 jets.

je me demande s´il y´a pas risque de passer dans le jetwash du tanker en prenant plein l´air chaud dans l´air inlet des jets derriere les 2 pod du centre (a la topgun)

Je sais pas trop,mais aussi je me suis posé ce genre de question,mais bon après c'est IAI c'est pas des amateurs ils ont surement du trouver la solution a ce genre de problème,les prochains Tanker qu'IAI doit livrer sont pour le Brésil,espérons que prochainement nous aurons les réponses a nos questions.

Si on pourrait avoir des infos sur la config adopté par les 2 clients, ce serait bien aussi.
