5. Multi-Dimensional Analysis

Economic - Capital push (+21.84%) crowds-in domestic defence manufacturing, MSMEs and start-ups via iDEX/ADITI [S2]. - 75% domestic earmark consolidates a multi-year trend; reduces import bill and FX outflow [S1][S9].

Strategic / Geopolitical - Highest-ever outlay signals deterrence posture against two-front threat (China-Pakistan). - Modernisation thrust aligned with theatre command rollout and post-Galwan capability gaps.

Scientific / Technological - DRDO hike of ~8.5% YoY; capital share (~₹17,250 cr) funds platforms like AMCA, hypersonics, drones [S1][S2]. - iDEX/ADITI funds private-sector deep-tech (AI, quantum, autonomous systems) [S2].

Social (Veterans' Welfare) - ECHS jump of 45.49% reflects rising medical costs and ex-servicemen rolls; ~33 lakh veterans benefit broadly [S1].

Administrative - Persistent issue: under-utilisation of capital budget and procurement delays under DAP 2020 (Defence Acquisition Procedure). - Revenue-heavy structure (pay, pensions) continues to crowd out modernisation despite capex jump.

• DRDO is under MoD's Department of Defence R&D, not under Ministry of Science & Technology.
• 75% earmark applies to Capital Acquisition, not to total capital expenditure or total budget.
• iDEX is executed by Defence Innovation Organisation (DIO) — a Section 8 company, not by DRDO directly.
• ECHS is for ex-servicemen, distinct from CGHS (central govt civilian employees).
