India can’t replace R-77 without Russian support
Recently, a news piece on NDTV's website suggests that the Indian Air Force (IAF) is planning to procure a longer range non-Russia air-to-air missile for its Su-30 fleet. The report claims that post-Balakot strike India is planning to procure Israel made I-Derby ER, an air-to-air missile with 100 km range. This is 20 km more than the range of R-77, a Russian medium-range air-to-air missile which is part of Indian Su-30 MKI arsenal.
