Examine the role of Defence PSU shipyards like GRSE in advancing Aatmanirbhar Bharat in naval platforms.

Defence PSU shipyards are the production backbone of India's naval self-reliance, converting indigenous design into combat-ready platforms. The commissioning of INS Dunagiri, INS Sanshodhak and INS Agray at Kolkata on 21 June 2026 — all designed by the Navy's Warship Design Bureau and built by GRSE, a Ministry of Defence PSU — illustrates both the strengths and the limits of this model [1].

Building indigenous design capability

• DPSUs translate in-house naval design into steel: Dunagiri is the 5th ship of Project 17A (7 stealth frigates, split between MDL and GRSE) [2].
• Sanshodhak, the last of four Survey Vessel (Large) ships, carries over 80% indigenous content by cost [3].
• Agray, 4th of eight ASW Shallow Water Craft, is among the largest Indian warships propelled by waterjets, with indigenous rocket launchers and shallow-water SONAR [4].

Anchoring the defence industrial ecosystem

• Dunagiri alone generated over 3,000 jobs and engaged 29 Indian OEMs and MSMEs; the three-ship programme drew participation from more than 200 MSMEs [1][2].
• DPSUs work alongside private yards — Sanshodhak was launched at L&T Kattupalli before delivery through GRSE — showing an emerging hybrid ecosystem [3].

Delivering balanced capability

• The three platforms span surface combat, hydrography and littoral anti-submarine warfare, addressing maritime domain awareness and the growing undersea challenge in the Indian Ocean Region [1].

Persisting constraints

• Critical propulsion, sensors and weapon subsystems remain import-dependent; indigenous content is measured largely by cost, not by technological criticality.
• Long build cycles — Dunagiri was launched in July 2022 and delivered in March 2026 — reflect capacity and supply-chain bottlenecks [2].

DPSU shipyards have thus moved India from buyer to builder, though not yet to full technological originator. Deepening design-to-subsystem indigenisation through the Positive Indigenisation Lists, sustained MSME participation and greater private-yard competition can close the remaining gap, making Aatmanirbhar Bharat the durable foundation of India's blue-water ambitions.
