1) RBE2 AESA was tested on Mirage 2000, so it's possible. RBE2 AESA is a 10kw power : no probleme with electricity. And if not always possible to change generator. If a 8 tons thrust TEJAS can have an AESA, a 10tons Mirage 2000 also. It's so simple it's strange you can't answer to your own question.
It does not depend on the weight of the plane but the amount of electricity that can be generated. And RBEE2 had been tested using Mystere and Mirage 2000 but that does not mean that its qualified on Mirage 2000, there is difference. But if so, is France planning to upgrade its Mirage fleet with AESA? There are no plans for that.
Spectra is not an off the shelf system. The location of all antenae is well established. And a lot of tests were made to assure electronic compatibility with the rest of the plane.
Spectra is one of the main argument of Rafale, and Dassaut don't want to maintain Mirage in production, so no need of integration on a fighter no more on production.
Mirage 2000 weakest 4th generation plane? No fighter in the world shoot down a Mirage 2000. Not the case in the other sens.....
And happy to read Mirage 2000 is a 4th generation plane...
SPECTRA is just the Data fusion of many off the shell receivers. RBE2 AA is part of SPECTRA, and also the various MWR and RWR on the plane. Sp as per what you say, just answer me few things
A) Does Rafale have RWR and MWR?
B) If they have, are these part of SPECTRA or not?
C) If they are not part of SPECTRA does Rafale have separate receivers on the plane for SPECTRA? Thus RWR + MRW + more separate modules for SPECTRA?
Mirage 2000 is not in production for a decade. ITs basically what user (AdlA) wants If AdlA want SPECTRA and RBE2 AA on Mirage 2000 and if Dassault can integrate it or not.
As far as I know both RBE2 AA as well as SPECTRA are not on SPECTRA and wll not be at all. If Thaies spent billion dollar on SPECTRA then they can spend a few million more to integrate them on Mirage and make it a 4th Gen plane, else its going to be shot down by the likes of F-16
