It will be highly critical if every one comments DRDO is a waste. We have not accounted for the success stories from DRDO organisation.Yes R&D takes time and we should be ready to accept the failures also. We make the best SONARS and RADARS for the Navy,The Gas turbine developed by is being tested in a naval warship, food research has given lot of positives. What MTR sells as ready to eat items are initially produce of DRDO lab. We have our processors developed. The EW system best suited for our country is home grown. I dont talk about the destructive wepons like Tanks and missiles, we all know the facts of success.
