Thales has revealed the first details of its new technology roadmap for the Dassault Rafale's radar and electronic warfare systems, which it believes could create opportunities to equip several other aircraft types over the next 20 years.

The new concept allows for the insertion of future technologies, such as gallium nitride transmit/receive modules, by using a so-called "cloud" architecture, says Pierre-Yves Chaltiel, head of electronic combat systems for Thales Airborne Systems.

Likely to be available within the next several years, the new T/R modules would enable Thales to reduce the depth of the antenna on the Rafale's RBE2 active electronically scanned array radar. Within a period of 10-12 years, it could also allow additional sensors to be embedded elsewhere within an aircraft's structure to enhance its overall sensor coverage.

The advance would also deliver increases in processing power, bandwidth capability and electronic counter-countermeasures characteristics, Thales claims.

For the Rafale, Chaltiel says a key benefit of the "cloud" concept would be to allow technologies to be added without having to re-qualify all the software used in the fighter's radar and Spectra EW packages. "The key is the systems knowledge - the processing power coupled with the radar and overall aircraft integration," he says.

The same technology could also be adopted for use by maritime patrol aircraft and airborne early warning platforms, or even offered as part of future mid-life upgrades for the Rafale, Eurofighter Typhoon and Saab Gripen under a possible co-operation agreement with other European radar manufacturers, Chaltiel believes. "Thales is ready and open for co-operation," he says.

French industry and the nation's DGA defence procurement agency have made combined investments worth over €1 billion ($1.2 billion) in sensor development for the Rafale over the last decade or so, and Chaltiel confirms that the nation is "already working on advanced technology demonstrators for the future".

Meanwhile, Thales will in August deliver the first of three production-standard AESA RBE2 arrays to the defence ministry to support test activities with the Rafale. The new sensor will enter squadron service in 2012 as part of France's December 2009 order for a fourth tranche of 60 Rafales.

"The system is far different, in range and capacity of intercept in a multi-threat environment," Chaltiel says.
