Egypt has sought to diversify its fighter fleet since the Fourth Middle East War to avoid a lack of spare parts and maintenance upgrades as relations with certain countries soured.
Now they have a large number of AIM7-only F-16Cs, M2000, Rafale, MIG29 with R530, R77, MICA, all of which lack long-range ARH missiles and all have good multi-role capabilities, In this case, multi-role capability and range will not be as urgent, but good radar, acceleration and long-range ARH missiles will be important.
If the Su35S deal had gone through, the RVVBD could have filled the gap in long-range engagement capabilities, but Russia clearly does not have the ability to supply these fighters, and the J10CE and PL15E that have just hit the shelves would have been a better choice in terms of both performance and supply stability.
