Muito antes disso Soultrain, Saab e Selex já cooperavam para o desenvolvimento de tecnologias AESA com suporte dos governos sueco e italiano (2006).Santiago escreveu:Pepe,Pepê Rezende escreveu: É o fim da picada que um cara que era levado a sério tenha aceito o papel de garoto propaganda da SAAB...
Quanto à SELEX, se a ligação fosse tão sólida, os suecos não teriam tentado contratos com a Raytheon, Thales e ELTA antes de voltar a procurá-la.

As coisas não são lineares e nem simplórias como vc descreve.
As empresas de defesa européias, todas cooperam muito entre si em diversos campos. Precisam de escala em P&D para não ficar para trás definitivamente. Nesta área (AESA) há programas conhecidos e recentes: AMSAR, KORRIGAN ( http://www.gaasmantech.org/Digests/2006 ... sts/3D.pdf ), etc que tem rendido bons frutos.
O contrato com a RAYTHEON ocorreu de fato. Foi para a aquisição de uma antena AESA customizada para o desenvolvimento da tecnologia de radares AESA pela SAAB. A THALES também utilizou modulos T/R da RAYTHEON para isso. Como se poderia desenvolver um radar AESA sem uma antena AESA? A Europa não era autosuficientemente nesta área, dai a necesssidade de importar componentes e os muitos programas conjuntos para o desenvolvimento de tecnologias (AMSAR, KORRIGAN etc).
Uma observação importante que impulsionou a cooperação e os investimentos europeus nesta área: (http://www.entrepreneur.com/tradejourna ... 91651.html ):Nor is there any prospect of procuring components for military applications from the US or Japan--both countries have already placed an embargo on GaAs circuits, and there is no reason for them to be any more flexible concerning GaN.

A relação entre a SAAB e a SELEX (2006), com financiamento e apoio dos governos de ambos países, para o desenvolvimento de aplicações AESA é anterior ao malfadado acordo entre a SAAB e a THALES (2008) para fornecer antena AESA para o desenvolvimento do radar do Gripen NG:
Com relação ao acordo entre a SAAB e a THALES, há um artigo de 2008, quando ele foi assinado, que esclarece bastante as coisas:Innovation » Design Innovations » Saab and Selex to Work on M-AESA Radar

(...) Saab Microwave Systems AB, Selex Sistemi Integrati S.p.A and Elettronica S.p.A. were recently awarded the second phase of a three phase Research and Development Program supporting the development of the next generation of microwave multi-function, multi-role systems called M-AESA (Multi-role Active Electronically Scanned Antenna).
On behalf of the armed forces of Italy and Sweden, the FMV (Swedish Defence Materiel Administration), has signed contracts with the three companies Selex Sistemi Integrati S.p.A., Elettronica S.p.A. and Saab Microwave Systems AB for Phase 2 of a 3-phase long-term strategic R&D effort regarding radar and electronic warfare (EW). The program will be fully financed by the two countries. The President of Saab Microwave Systems AB referred to efforts that would ”...greatly enhance our joint possibilities to achieve the product vision of a true multi-role electronics package capable of active and passive sensing, jamming and special communications.” That last bit is especially interesting in light of recent US developments, and in the short term the program is meant to “contribute to the development of multifunction radar and EW systems.” (...)
Com relação ao radar AESA da IAI/ELTA, ele já estava desenvolvido no ano passado. Ou seja, a frente de qualquer opção européia. Com o uso de tecnologia americana é mais fácil. Se caminho fosse um desejo da India, devido a boa cooperação com os israelenses, se ganharia tempo e evitaria problemas com relação prazo dos ensaios. Mas os indianos aceitaram dividir o ensaio com o Gripen em 2 etapas, primeiro com os Gripen C/D e depois com o Gripen Demo NG já equipado com o radar AESA da SELEX/SAAB.Saab and Thales develop Gripen radar
Today, Saab announces a collaboration with the French company Thales. Together they will develop a new advanced radar based on AESA technology for the Gripen demonstrator, which will be shown for the first time during the day.
2008-04-23 | “This is a major step in the development of radar and an important collaboration. An AESA radar (Active Electronically Scanned Array) opens a series of new possibilities and functions,” says Peter Andersson, product manager at Saab Microwave Systems.
As opposed to the mechanically controlled antenna currently used in the Gripen radar, which can only illuminate one area at a time, an AESA radar can search larger areas faster, follow more targets in parallel and permits the pilot to operate more flexibly.
The collaboration is for the Gripen demonstrator
The collaboration surrounding the AESA radar started last autumn. Saab Microwave Systems is responsible for the radar system and its capability. Thales contributes with the antenna and Saab Aerosystems is responsible for the integration in the aircraft.
Integration of the complete radar system will continue during 2008 and will be completed in the spring of 2009. The first test flights are planned during the summer of 2009 and thereafter Saab intends to display the system at different customer demonstrations.
AESA technology in more of Saab’s products
That the collaboration is with Thales is explained by Peter Andersson as follows:
At present Thales is developing an AESA within a French radar programme and, like Saab Microwave Systems, is one of the world leaders within the radar field. Together we can quickly develop a demo-product that can show the markets the advantages of AESA technology. The collaboration over the antenna is also cost effective and is in line with Saab’s overall strategy of finding industrial partners for Gripen.”
But Peter Andersson does not want to speculate whether the collaboration with Thales will continue with the development of AESA radar for the next generation Gripen:
Our collaboration is for the Gripen demo. We will have to see what happens in the future.”
AESA technology is already in use in several of Saab’s products, such as the Erieye airborne early warning system, the short-range search and acquisition radar Hard, the surveillance radar system Giraffe AMB and the artillery locating radar Arthur.
Quando surgiu essa questão, o desenvolvimento do radar AESA da SELEX/SAAB já estava em pleno andamento e no início de 2010 foi testado na India.

(...) The Israeli defence ministry and IAI have refused to comment on the report, but Saab-led Gripen International confirms that "Israel was one of several options" assessed for the radar element of its bid for the Indian requirement. The Swedish manufacturer has already confirmed its intention to allow India to conduct a flight evaluation of its Gripen Demo airframe equipped with a Vixen 1000E/ES05 Raven active electronically scanned array radar from Finmeccanica company Selex Galileo, and has approvals in place to export the system to India, and other potential Gripen buyers Brazil and Switzerland.(...)
E a relação com a Thales foi explicada no dia da assinatura do acordo em 2008.
