By 2024. Engine power will be most probably be 66 kn dry. Mirage 2000 does all this with even slightly lower power engine.
Combat power ratio of ideally 1:1 is important as this will also be a naval jet. Although good load potential for a bomber but it will still be under powered for a 4.5 gen jet. India needs to look at a power plant of 120KN range since this is no longer a light jet.

Empty 8 ton
With internal fuel 11.5-12 ton
Full take off 17.5 ton
