Beyond Sea Drones: India's Autonomous Maritime Systems Ecosystem 2026-2035

India's autonomous maritime systems (USV/UUV) market is projected to grow from a INR 2,200 crore 2026 baseline to INR 11,500 crore (Constrained), INR 35,000 crore (Baseline) or INR 55,000 crore (Accelerated) by 2035. This strategic intelligence report maps the ecosystem from primary sources, with every major claim numbered and verification-labelled [IN-XXX]. India ranks 9/12 on the proprietary Maritime Autonomy Readiness Index with a composite 4.5/10: fourteen active programmes and eight iDEX awards exist, but the subsystem base is only 15-70% indigenous (AI silicon ~15%, battery cells ~35%) and there is no certification authority. The report reframes the debate from platforms to subsystems, quantifies the MDA and ASW coverage gaps, benchmarks six countries (US, China, UK, Israel, South Korea, Singapore) with reconstructed 2024 budgets, and scores 100 opportunities on the 9-dimension Opportunity Priority Index (OPI) — 24 "Star" opportunities score 80+, led by an 11-metre ASW USV at 88. It closes with a three-phase 2026-2035 roadmap (INR 14,600 crore Phase I, 8-12x return on capital) and 45 recommendations across government (12), the Indian Navy (10), industry (10), startups (10) and investors (8). 136 pages, 29 chapters, 53 figures, 15 tables, 125 numbered sources and full appendices A-L, mirrored in a 17-sheet data workbook.
