Yes I agree with you guys. The problem is everybody wants money. Who ever joins DRDO is feeling bad once their friends in IT/MNC'c earning more than them. A well learnt junior scientist(-B) of 2-3 experience is using his learnt knowledge in IT/MNC's by leaving. Make DRDO knowledge rich by giving the scientists better pay-package as comparative to MNC's. First and foremost thing is reduce the attrition. I am sure the best research and development work you could ever do is there in DRDO. And One more thing is a good management at senior level and constant motivation in terms of financial and morale will give definitely a great results.
