Well dosent the RDY-2 operate with Gallium Arsenide instead of the latest Gallium nitride in their AESA Radars? Will this be some kind of obstruction to the Rafale and give the EFT a chance?
RDY 2 is the radar of the upgraded Mirage 2000-5, the Rafale currently uses the RBE 2 PESA and the version offered in MMRCA will have the RBE 2 AESA radar. No AESA radar today uses GaN modules and the Europeans has joint developments in that area, but lead by EADS (inluding the French part) and Thales. It is expected that the first operational GaN modules will be integrated into SPECTRA and later into RBE 2 AESA. The Eurofighter will get GaN modules in future too, but since not even the current radar is in a proper development stage, this can take quiet some time!
So in MMRCA this won't play a big role, other than the future potential with GaN modules looks brighter for Rafale, since it's more likely to get that tech and get is earlier than EF, just like the AESA radar in general.
