I found another caption for the image with a bit more detail.
“The N001VEP+Pero phased-array radar (PESA) on Su-30 No. 597. In 2003, NIIP proposed a new lightweight, space-fed reflectarray antenna intended to replace the N001 radar antenna without requiring a completely new radar design. The radar was also proposed for the Su-30MK3.”
If I had to guess, china wanted the extra A2G hardpoint of the 27M, but didn’t want the extra cost of putting the newer wings that can use a ton of A2A onto the Su-30 platform?
I don’t know. But considering the state of the PLAAF in the late 90s early 00’s it would make sense that they would want a cheap but capable aircraft.
It is still a wing similar to Su-27M because Su-27 wing doesn’t have pylons there at all. But by not installing connectors, data buses (USSR and Russia at the time weren’t big on standardised data buses iirc) and FCS upgrades you can make it not as expensive?
Well, MKI in itself is more expensive because India wanted a bunch of shit integrated, and also paid for technology transfer. But looking at MK2 contracts, they are around 80 mil USD a piece. MKI of the latest batches with domestic Indian stuff go around 110-120 mil USD. Hilariously enough, Su-30SME costed Myanmar around 66 mil USD per unit
Overpaying for Rafales because they simply can. But honestly i am impressed with SME cost, 66 millions is with all additional service, training and weaponry, just the jet itself is like 35 mils. F-16 Block 70 is what, 60 mil per airframe itself?
