A good transport fleet will be required post 2030.
Our il-76s are getting too old and our An-32s need immediate replacement.There is room for more C-130/Airbus A-400M class aircraft.Plus our civil aviation sector will grow meaning requirement for Airbus a330/a350 type jets.

This timeline(2020-25) is the best time to kickstart such a program.A c-17,c-130 and An-32 replacement aircraft.Later such skills can be used to build civil aviation industry.
We could take a short cut by joining kc390 program with Embraer .
If we take over Embraer we will have a regional jet ej145 as well as a military transporter kc390.
Otherwise we are anyway going forward with saras 2 and RTA 70/90.
Transporter are far far easier then fighter jets.
Our designers after developing lca , mwf ( design froze) and tedbf will find transporter design as paid holidays.
Civilian passenger jet is more difficult as it will have to beat competition in fuel efficiency and maintenance only then it could sell.
