Q. Trace the evolution of the Pinaka Multi-Barrel Rocket System from the Kargil War to its current guided variants. What does this indicate about India's defence R&D trajectory? (15 marks, 250-350 words)

Named after Lord Shiva's bow, Pinaka began as an indigenous replacement for the Army's Soviet-era GRAD BM-21 launchers and has since matured into a guided, long-range precision system — a trajectory that mirrors India's shift from import substitution to indigenous technology leadership.

Evolution of the system

• Kargil War (1999): Pinaka Mk-I, still under development, was pressed into service during Operation Vijay, proving effective against entrenched infiltrator positions and validating the design [4].
• Area-saturation phase: The classic MBRL configuration — 18 launchers with 12 tubes each (216 tubes) delivering about seven tonnes of explosives in 44 seconds, neutralising a 700×500 m area [4].
• Range extension: Pinaka Mk-II, developed by ARDE, Pune, achieved a 60 km reach using the existing launch vehicle with only minor modifications [4].
• Munition diversification (2020-22): Successful flight tests of Pinaka Mk-I (Enhanced) and the Area Denial Munition (ADM) variants at Pokhran, with rockets produced by industry under Transfer of Technology [5].
• Guided phase (2024): DRDO completed flight tests of the Guided Pinaka Weapon System [6]; multi-stage PVT trials at Balasore, Pokhran and Ladakh met all PSQR parameters, and induction was recommended [3].
• Long-range guided phase: Maiden test of the LRGR-120 at its maximum 120 km range (December 2025) [2], followed by validation at the user-defined minimum range of 60 km on 8 July 2026 at ITR Chandipur [1].

What it indicates about India's defence R&D trajectory

• Incremental, platform-anchored innovation: LRGR fires from the in-service Pinaka launcher, allowing variants of different ranges from one platform — capability gains without costly re-equipping [1].
• From volume of fire to precision: In-flight manoeuvre and guidance-kit integration signal a move toward precision-guided munitions [1].
• Lab-to-industry ecosystem: ARDE with HEMRL, DRDL and RCI, plus ToT-based private/PSU production, deepens the domestic defence-industrial base [1][5].
• Rigorous certification culture: Testing both range extremes certifies the full operational envelope [1][2].

Pinaka thus traces India's arc from emergency battlefield improvisation to systematic, self-reliant weapon development. Sustaining this trajectory requires stable funding, faster lab-to-induction cycles and deeper private-sector participation, so that Atmanirbhar Bharat in defence translates not only into strategic autonomy but also into a credible export capability.
