Strategic Imperatives of Indigenous Missile Development: India's Pursuit of Self-Reliance in Defence Technology
India's push for indigenous missile development, a core component of its strategic autonomy, faces complex challenges despite robust policy intent. This analysis uses a hypothetical 'Blue Sparrow Missile' program to dissect the institutional frameworks, technological hurdles, and policy implementations governing India's journey towards self-reliance in defence technology.
THAAD Missile System: Geostrategic Implications, Capabilities, and India's Strategic Calculus (UPSC GS-III)
The THAAD Missile System, a cornerstone of US layered missile defense, intercepts ballistic missiles in their terminal phase, leveraging advanced radar and kinetic-kill technology. Its deployment has significant geopolitical ramifications, particularly in East Asia, creating strategic stability paradoxes and diplomatic friction. For India, understanding THAAD's operational and strategic dimensions is crucial for informing its own indigenous missile defense aspirations and navigating complex regional security dynamics.
