Of course, the United States today is just about the only country that can afford scores of dedicated electronic- attack aircraft and the cast of thousands of highly trained experts who support them. "The US has specialized EW aircraft that cover an area and so take some of the burden off the strike aircraft in terms of self- protection." said Dov Granot, business development manager for the Elisra Group (Bene Beraq, Israel). The Israeli Air Force favors a system where select aircraft in a strike package are equipped with escort- jamming pods. "Israel's philosophy is that an aircraft needs to be able to protect itself from start to finish, from take-off through landing."

Jean-Philippe Gourion, deputy director of strategic planning for Thales Airborne Systems (Paris, France), said Thales is working on an escort-jamming concept in which dedicated platforms and crews would be replaced by a combination of integrated systems featuring a solid-state, phased-array jammer with very high transmitted power and real-time multi-beam steering. This would be fitted in an automatic pod carried by a multirole fighter for the stand-in/escort jamming mission. Since 1993, Thales has been developing its Carbone offensive jammer demonstrator under contract to the French military procurement agency. According to Gourion, the Carbone is significantly more powerful than existing or upgraded offensive-jamming pods. Carbone also draws on Thales' digital receivers and real-time geolocation algorithms, such as those implemented in the Spectra EW system for the Rafale aircraft.

A fighter aircraft carrying a pod-mounted phased-array jammer would have the ability to loiter at the periphery of the threat area, but not necessarily in line with the flight path of the strikers. Once the strike package is about to enter the threat area the electronic attack aircraft is alerted by datalink to commence jamming through the secondary or scattered lobes of the threat emitters. Thus, the enemy would remain unaware of the direction of the strike package's arrival. Gourion pointed out that there would be some burden during the mission-planning phase to ensure that timing, waypoints, and jamming duration are synchronized. "In fact, if your mission planning is excellent, then you are not obliged to use a datalink or otherwise transmit between the strikers and jammer aircraft," he said.

Another benefit of this approach to stand-in/escort jamming is that the electronic-attack aircraft does not have the same demands on its self-protection jammers, thus eliminating the potential for interference. In fact, Gourion questioned the wisdom of even attempting to operate electronic-attack and self- protection systems on the same aircraft at the same time. "Frankly speaking, I don't think that it would be a very good idea to use stand-in jamming tactics other than those that attack side or scattered lobes at some distance," he said. "If the electronic-attack aircraft is loitering at very low altitude somewhere in a relatively safe place quite close to the danger zone, then you can decide at a given instant to pop up and begin your jamming job."

tem um post do nosso amigo rcoliteste discorrendo sobre o MI-35 na FAB muito bom, está perdido por ai ...ele resumiu oque acontece....nada haver com fofocas e murmúrio de pessoas de fora...acredite, no "operacional" o papo é outro.

Não sei se é impressão minha, mas cada vez a passagem lenta do Rafale, está mais lenta. Quase parou no ar.

Mas estou com a impressão que, SE VIER ALGO da short list, será o Super Hornet. Se fosse para dar Rafale o Lula já tinha assinado...

Apenas uma impressão, naturalmente (e não há garantia alguma de que nos vendam GROWLER e seus pods ou que sequer a FAB saiba o que é isso e queira, já os Franceses talvez sejam mais flexíveis aí)...

E sabe tambem que uma aeronave para ser AEW de verdade TEM que ter pelo menos 2 tripulantes, e MUITA potencia para suprir seus equipamentos (se precisa de potencia, precisa de espaço; se precisa de espaço precisa ser grande).
