PM Modi to commission 3 indigenously built naval ships in Kolkata on June 21

📌 Summary:

• The Indian Navy will commission three indigenously built frontline platforms — Dunagiri, Sanshodhak and Agray — in Kolkata on Sunday (June 21), with PM Narendra Modi presiding
• Dunagiri is an advanced stealth frigate (the fifth Project 17A frigate), equipped with BrahMos surface-to-surface missiles and a medium-range surface-to-air missile system; Sanshodhak is a large survey vessel; Agray is an anti-submarine warfare shallow-water craft
• All three were designed by the Indian Navy's Warship Design Bureau and built by Garden Reach Shipbuilders & Engineers (GRSE), Kolkata
• The platforms span maritime combat, hydrographic surveying and anti-submarine warfare, reflecting a "balanced approach" to capability development — strengthening blue-water operations, enhancing maritime domain awareness, and securing coastal waters
• Underscores indigenous warship design-and-build capability and the Atmanirbhar Bharat push in defence

🎯 UPSC Relevance: GS3 — indigenisation of defence technology, self-reliance (Atmanirbhar Bharat) in warship building, and India's maritime/blue-water naval capability.
