Q. Differentiate between the roles of DRDO and the Strategic Forces Command in India's missile testing ecosystem. (15 marks, 250-350 words)

India's missile testing ecosystem rests on a deliberate separation between the developer and the user: the Defence Research and Development Organisation (DRDO) designs and proves the technology, while the Strategic Forces Command (SFC) — the tri-service custodian of nuclear delivery systems — operates and validates it in service conditions. The distinction is functional, not hierarchical.

DRDO — the developer and technology certifier - A Ministry of Defence R&D agency; designs, integrates and flight-tests missiles through developmental trials at facilities like the Integrated Test Range, Chandipur [1]. - Owns critical sub-systems: Agni-4's two-stage solid propulsion, Ring Laser Gyro-based Inertial Navigation System with a redundant micro-navigation backup, and a re-entry heat shield withstanding extreme temperatures [1]. - Drives indigenisation — the Agni series descends from the Integrated Guided Missile Development Programme, and DRDO conducts first-of-type trials of new variants such as Agni-Prime [2].

SFC — the user and operational validator - A tri-services command under the Nuclear Command Authority, responsible for custody, deployment and delivery of nuclear weapons. - Conducts user/training trials of already-inducted systems, checking crew proficiency, mobility and launch drills rather than novel technology — the Agni-4 launch of August 2026 from Chandipur was carried out "under the aegis of the Strategic Forces Command" and validated all operational and technical parameters [3]. - Translates capability into credible minimum deterrence, signalling readiness under India's No-First-Use doctrine.

Where they converge Newer systems are flight-tested jointly by SFC and DRDO, as with Agni-Prime off the Odisha coast — DRDO certifying performance, SFC certifying employability [2].

The two therefore form a continuum from laboratory to launch pad: DRDO answers "does it work?", SFC answers "can we use it when required?" Strengthening this handover — through faster induction cycles, joint trial planning and greater private-sector participation in defence manufacturing — will deepen strategic self-reliance and give India's deterrent both technological credibility and operational assurance.
