DRDO: India's Defence Research Backbone and Strategic Powerhouse
“If you aspire to be a great power, you must first become self-reliant in defence.” — A.P.J. Abdul Kalam
India’s quest for strategic autonomy and self-reliant defence capabilities finds its bedrock in the Defence Research and Development Organisation (DRDO). As the R&D wing of the Ministry of Defence, DRDO plays a pivotal role in designing, developing, and delivering advanced defence systems and technologies, positioning India as a rising power in global defence innovation.
This comprehensive blog explores DRDO’s historical roots, organisational structure, technological achievements, major projects, multidimensional impact, challenges, collaborations, global relevance, and future roadmap. With its blend of scientific excellence and patriotic mission, DRDO is not just a defence entity — it’s the scientific soul of India’s armed forces.
