Integration of an AESA into the Flanker airframe will not present difficulties, as there is considerable internal volume, large internal fuel capacity with potentially large cooling capacity, and electrical power to spare with the newer engine designs.
The large 0.9-1.1 metre diameter aperture provided by the nose and radome design will be especially attractive to an AESA designer. This aperture size permits around twice as many AESA modules of similar size to most current Western designs, apart from the F-22A Raptor APG-77 and F-15C APG-63(V)3/4, to be packed into the antenna.
The implications of this are sobering, insofar as with modules rated at half the peak power of the current state-of-the-art, such a radar could provide about the same peak power rating as current top end US AESAs. The Power Aperture Product would thus be higher due to the aperture area being so much larger. With COTS derived modules of much higher peak power rating than current US military GaN HEMT technology, a future Flanker AESA could have a very much higher Power Aperture Product figure, with significant counter-stealth potential.
