It would interest you to know that self development of fighter
planes has been a desire of India for 5X years now.
The problem has been engines.
Even in the early years, India manufactured the HF-24
marut fighter and got into problems with the engine (Read about
BOr, Orpheus 703, RD-9 issues).
Fast forward to the LCA or Tejas. India wanted indigeneous
engines ie Kaveri for the LCA. Went into a lot of problems and now
ends up with the F404 after goodness knows how long a development
period that practically guarantees the aircraft will be obselete on
entry.
China on the other hand, basically got into licensed production
arrangements. Nevertheless it faces the same problems as India
except that it had better capabilities in engine manufacture eg
WP-9s for the J-7s. It still runs into issues eg lack of RD-93 for
export FC-1s.
India still does license productions fairly well
eg Su-30mki except that the AL-31 engines are still
proprietorily held by the Russians. China tried to copy the speys
for the JH-7, took 20 years and still ended up signing a license
production of the engine for the JH-7As.
Ultimately, if India is to be successful, it will need to
manufacture its own engines. As the kaveri example shows, its not
that easy.
