Theirs and the Indians are the same non-streamlined hodgepodge. Connectivity is key.
There is no reason for them to pursue a new fighter if it can't stand a chance against their nextdoor neighbour. What they currently have have is sufficient for all other countries.
I second this. Even with J10c I don’t see Egyptian challenging Israel unless they revamp the whole doctrine and incorporate C4ISR
Just an add-on.
Many people may not know this, but Israel isn't the only country with significant conflict of interests with Egypt in the region (which is mainly regarding the Palestinian cause).
Unlike the China-US (in the WestPac) and NATO-Russia (in Europe) rivalries, which are pretty clear-cut in terms of "you're either on my side (i.e. friend, ally) or on my opposite side (i.e. rival, enemy)" - There are more than two poles spread across West Asia that are vying to set up their own spheres of influences, namely:
1. Iran
2. Saudi Arabia
3. Turkey
4. Egypt
and of course, Israel. Their aspirations and interests sometimes align with one another, though equally if not more often, present conflicts with other poles of power in the region, at least under certain circumstances if not in general.
For Egypt's case, their main rival would be Turkey. This mainly evolves around maritime oil-&-gas exploration rights in the Mediterranean, alongside the Libyan crisis since 2011, where the main belligerents in the Libyan conflict were supported by Egypt and Turkey on opposing sides.
Of course, there are also the historical and geopolitical factors between both countries at play.
Then, there are also the Halaib Triangle border dispute with Sudan, alongside the Nile water supply issue with Ethiopia, albeit both these countries don't really pose peer-worthy military threats towards Egypt.
Hence, it'd be pretty normal for Egypt to pursue a sufficiently strong military (including its air force), whilst still not become too powerful (or to be more accurate, too sophisticated) that could pose a direct challenge to the Israeli military, as this would risk DC's wrath (as that Egypt is still reliant on the US for military aid).
