That's not the point. You are asking about one missing MKI from MoD's RFP and assuming that it was shot down last year which is completely wrong. No MKI was shot down last year and was our ONLY frontline jet that dodged all PL-15s & HQ-9s.All jets are upgraded, even the ones with other agencies. Other agencies have been assigned multiple MKIs already. DRDO has 2.
Regarding one missing MKI, you can search about SB-025 that is permanently stationed at ASTE in Bengaluru. It is not counted as part of active combat fleet as it's a permanent fixture there as part of our avionics test-bed.
