117 is only used on the PAK FA prototypes, and you just proved me right because nether Su-34 or Su-35 have AESA radar, or L-band radar.
That's what you claim, but so far I take the statements of Russian officials as more reliable. Btw, I never stated anything about AESA radar or so, that's what you did. I pointed out the systems the early Pak Fa will have as modernised parts of the Su 35 and 34.
and all the items you just posted are available on this aircraft
Not really, it neither have the 117 engines of the Su 35, but the same AL 31 with TVC that MKI has as well, neither does it have the IR MAWS, nor the SATCOM of the Su 34, if at all, it has the same IRST, but that's it.
The size of a radar is not fixed, additional AESA modules can be added to a bigger nose, that's why the Russians integrated 3 x different Zhuk AEs into Mig 35 prototypes, to reach the promised 200Km detection range, by increasing the nose diameter. The problem is, that weight will be increased as well and the radar turned out to be too heavy and they had to stick to smaller versions, with less range again.
Zhuk AE in MKI would have a diameter of around 900mm, while it had 688mm in the Mig, so much space for more modules and more power.
Well, you guys want a AESA radar for the upgrade, and Irbis-E is PESA radar so thats marked off the list, Tikhomirov Scientific Research Institute of Instrument Design is the company that makes bars radar, and they have stopped developing bars line now and their concentrating all their efforts on making a AESA radar for PAK FA.
Wrong, they have developed an AESA version of BARS, which is not that complicated anyway and it is on offer for IAF as well, but so far there is no decision made about which radar IAF will procure. BARS AESA will be an easier upgrade for IAF and sticking with Tikhomirov is the better option for the future too, since they will develop the radar for Pak Fa / FGFA as well.
