The IAF’s depleting strength has been public knowledge for decades now. Other than the Sukhoi-30 MKI procured in the 1990s, the squadrons have had shrinking strength due to a depleting core of MIG 21s. While India dithered, Chinese indigenous aircraft development and supplies to Pakistan expanded, besides new Chinese airfields in the Tibetan Administrative Region (TAR). Consequently, the government in 2001 issued a Request for Information (RFI) for the procurement of Medium Multi Role Combat Aircrafts (MMRCA). India was looking to replace its MIG 21s, an outdated interceptor, slotting the new fighters between the high-end Sukhois, upgraded Mirages and MIG 29s and the low-end Light Combat aircraft (LCA) being developed indigenously.
