I read above article and I don't think that only DRDO is responsible for the delays or in developing the war machines. We are comparing DRDO with those agencies which are developing these types of mochines over 100 years. To develop any war machine we need time, money and skilled brain power, in which we are lacking. We should remember that to develop the atom bomb US agencies failed many times.
So, we should not critisized while we should encourage young youth and good brain to join DRDO.
