This is how India's biggest defence deal - a $10.4-billion tender for 126 combat aircraft - panned out:

* 2000: Indian Air Force (IAF) conveys to defence ministry its interest in acquiring medium multi-role combat aircraft (MMRCA) to replace its ageing fleet of Soviet-era MiG-21s and because of delays in developing the indigenous light combat aircraft (LCA).

* 2001: IAF issues request for information (RFI) for 126 combat jets.

* 2003: IAF seeks defence ministry's permission to buy 50 more French Mirage-2000s to shore up the only MMRCAs in its fleet as a stop-gap arrangement. The aircraft had been acquired in the mid-1980s.

* 2004: Defence ministry asks IAF to instead issue a larger MMRCA tender.

* 2005: Defence ministry issues initial MMRCA tender but withdraws it quickly even as it starts receiving responses from vendors.
