India is unlikely to rely entirely on large fighter formations in a future conflict. It can lean heavily on stand-off weapons instead. The roughly 40 Su-30MKIs modified to carry BrahMos can provide a substantial long-range strike capability, while Jaguars can employ Storm Shadow and Rafales can employ SCALP.
Once Tejas enters the picture in larger numbers, this becomes even easier because it can integrate a broad range of Indian cruise missiles, glide bombs and laser-guided weapons. Until then, the existing 40 modified Su-30MKI fleet should be sufficient for a significant portion of the stand-off strike role—even with around 50% availability, that would still leave roughly 20 aircraft available.
Upgrading the entire Su-30MKI fleet for BrahMos may not be economically practical, given the nearing retirement of the aircraft and the increasing induction of Tejas. The focus will be on getting the most capability from the platforms already modified while transitioning toward newer platforms.
