Examine the role of DRDO-DPSU collaboration in indigenising precision-guided munitions in India.

Precision-guided munitions (PGMs) — weapons steered to a target by satellite, laser or inertial guidance — were long an import-heavy segment of India's arsenal. Their indigenisation now rests on a division of labour in which DRDO designs and a Defence PSU serially produces, a model best illustrated by the Smart Anti-Airfield Weapon (SAAW).

How the collaboration works

• Design-to-production chain: DRDO's Research Centre Imarat (RCI), Hyderabad designed SAAW, sanctioned in 2013; Bharat Dynamics Limited (BDL) now manufactures it [1][2].
• Procurement anchoring: the Rs 811 crore contract for 160 SAT-SAAWs (September 2026) was placed under Buy (Indian-IDDM), the top indigenisation category of the Defence Acquisition Procedure, which requires indigenous design and development [1].
• Sub-system deepening: indigenous inertial measurement units, impact-delay fuses and carriers raise domestic content, cutting dependence on imported guidance kits [1].

What it has delivered

• Capability: a ~125 kg glide bomb striking airfields from a ~100 km stand-off range, launchable from Jaguar, Hawk-i and Su-30 MKI [1][2].
• Industrial base: defence exports rose from Rs 686 crore (2013-14) to Rs 38,424 crore (2025-26), with about 3,000 of 5,500-plus listed items indigenised by February 2025 [5].
• Strategic autonomy: owning the design allows seeker or warhead upgrades without foreign clearance.

Constraints the model still faces

• Time overruns: thirteen years separated SAAW's sanction from its first production order [1][2]; the Standing Committee on Defence (2023) found 23 of 55 DRDO projects delayed, citing technical complexity, price inflation and technology denial by foreign suppliers [3].
• Sequential reviews: the same Committee urged revisiting review mechanisms that themselves cause delay [3].
• Absorption gap: munitions mature faster than carriers — the IAF held 31 fighter squadrons against 42 authorised (December 2024), while capital outlay is only 29% of the 2026-27 defence budget against the 40% recommended [4].

The DRDO-DPSU pathway has demonstrably converted laboratory designs into fielded, exportable PGMs. Sustaining it requires concurrent production tooling alongside user trials, predictable repeat orders to keep DPSU lines warm, and restored transparency on committed liabilities — so that self-reliance under Atmanirbhar Bharat is measured not by one contract, but by continuous capability.
