                          Challenges Faced by DRDO<\/h2>\r\n

                          While DRDO has achieved success in many technology domains, some persistent challenges affect its performance:<\/p>\r\n

                            \r\n\t
                          • Delays in projects:<\/strong>\r\n
                              \r\n\t
                            • Complex defence projects executed by DRDO often face time and cost overruns, leading to delays.<\/li>\r\n\t
                            • For instance, the\u00a0LCA Tejas\u00a0<\/strong>took over\u00a03 decades\u00a0<\/strong>to complete. Delays lead to\u00a0cost escalation<\/strong>\u00a0and\u00a0opportunity costs\u00a0<\/strong>for the armed forces.<\/li>\r\n\t
                            • Causes include overambitious project scope, lack of experience, changing requirements, technical hurdles, inadequate project management etc.<\/li>\r\n<\/ul>\r\n<\/li>\r\n\t
                            • Dependence on imports:<\/strong>\r\n
                                \r\n\t
                              • Despite advances in indigenous technology, India still imports a substantial portion of its defence equipment.<\/li>\r\n\t
                              • Critical components and subsystems used in major projects like aircraft, submarines, electronics<\/strong>\u00a0etc. are still imported. This affects self-reliance.<\/li>\r\n\t
                              • There is over-reliance on foreign\u00a0Original Equipment Manufacturers<\/strong>\u00a0(OEMs) for critical design consultancies and some technologies due to a lack of expertise.<\/li>\r\n<\/ul>\r\n<\/li>\r\n\t
                              • Budget constraints:<\/strong>\r\n
                                  \r\n\t
                                • Defence research requires sustained long-term investments which have been inadequate. DRDO's budget is currently about 8% of the defence budget.<\/li>\r\n\t
                                • This affects the ability to retain talent, infrastructure creation, conduct advanced R and D etc. resulting in delays.<\/li>\r\n\t
                                • The launchpad for an advanced defence R and D ecosystem is missing unlike in advanced defence countries.<\/li>\r\n<\/ul>\r\n<\/li>\r\n\t
                                • Jet Engines:<\/strong>\u00a0India still imports engines for combat aircraft and tanks due to challenges in mastering key technologies like single crystal blades, cooling systems etc. LCA Tejas uses imported\u00a0GE-404 engines.<\/strong><\/li>\r\n\t
                                • Semiconductors:<\/strong>\u00a0India lacks commercial-scale semiconductor fabrication facilities and depends on imports for chips used in radars, avionics, electronic warfare systems etc. This affects self-reliance in electronics.<\/li>\r\n<\/ul>\r\n

                                  Way Forward<\/h2>\r\n

                                  To improve its effectiveness, some measures that DRDO should undertake are:<\/p>\r\n

                                    \r\n\t
                                  • Talent Management:<\/strong>\u00a0Implement attractive merit-based pay structures, fast-track career growth for high performers, and sponsor higher studies to retain and motivate scientists.<\/li>\r\n\t
                                  • Academia Collaboration:<\/strong>\u00a0Joint R and D projects, industry-sponsored academic chairs, student internships, and faculty sabbaticals to tap into external talent pools and research capabilities.<\/li>\r\n\t
                                  • Defence PSU Reforms:<\/strong>\u00a0Strategic partnerships, joint ventures with private firms, greater R and D investments, enhanced operational autonomy, and developing internal R and D capabilities to improve competitiveness.<\/li>\r\n\t
                                  • Startup Ecosystem:<\/strong>\u00a0Provide access to testing infrastructure, funding, purchase guarantees, and relaxed procurement norms to incubate a vibrant defence startup ecosystem through initiatives like\u00a0iDEX, DIStAC<\/strong>\u00a0etc.<\/li>\r\n<\/ul>\r\n

                                    As the source of strength of a nation in both peace and war is driven by science and technology, the establishment of DRDO is in the right direction, and when India is prioritising strategic autonomy across the sectors, entities like DRDO assume even greater importance. With the right strategy and ecosystem, DRDO can build on its achievements to realize India's dream of self-reliance in defence technologies.<\/p>","protected":false},"excerpt":{"rendered":"
