I rather sense some humor in your post than anything of credibility.
That very poor country you are talking about spends over $34 billion annually on its defence forces.And spends over a billion on its strategic command.And that pity DRDO you are talking about spends nearly 12000 crore rupees on development of new technologies.
I agree withyou on one thing. On a comparison scale Indian falls behind many mamoths like US,Russia,UK,France,. but nevertheless it lagged behind too much.
that very same Arjun you are talking about is already in production and improved variant will go into production soon.Same happened to the lightest of all combat aircrafts LCA.Deal has been signed with GE for 99 engines, not for the sake of storing them in the warehouse,but to power the next 99 MKII a/c.
Unfortunately even critics appreciated Akash(one under long time development program)about its robustness and kill probablity.Which further got over $10 billion orders.
All you can brag about DRDO failures is a Trishul TD program.Even the tech developed for Trishul is going into Maitri(hence not a waste of money and time)
Every paisa spent by DRDO was utilised properly and will be used to spearhead the increase in indigenisation content.
Sometime an unresearched subject is not worth to argue about.Maybe you should better comeout with a subject that was well researched by you.
