The Defense Research and Development Organisation (DRDO) is responsible for the development of technology for use by the Indian armed forces. In recent years it has been criticized for the delayed projects and cost over runs. Because of DRDO’s poor performance in successfully delivering weapon systems and meeting timelines country fulfill its 70% of defense needs by imports from various countries.
Apart from these criticism most of which are irrational and unfair to the part of DRDO, there are many weapon systems which were largely managed by DRDO have seen considerable success with many of the systems seeing rapid deployment as well as yielding significant technological benefits. DRDO has achieved many successes since its establishment in developing other major systems and critical technologies such as aircraft avionics, UAVs, small arms, artillery systems, EW Systems, tanks and armored vehicles, sonar systems, command and control systems and missile systems.
It is very difficult to short down top 10 weapon system developed by DRDO as it has developed so many weapon systems. Based on the technological challenges, strategic importance, defense needs and level of completion of the systems these are top 10 weapon systems developed by DRDO.
