India, June 21 -- Prime Minister Narendra Modi on Sunday commissioned three indigenously designed and built naval platforms - INS Dunagiri, an advanced stealth frigate; INS Sanshodhak, a large hydrographic survey vessel; and INS Agray, an anti-submarine warfare shallow water craft - at Syama Prasad Mookerjee Port in Kolkata.

According to a government statement, the induction of the three vessels will significantly enhance India's operational capabilities, strengthen maritime domain awareness and bolster the security of the country's coastal waters against emerging geopolitical challenges.

With over 75 per cent indigenous content, the vessels underscore India's commitment to self-reliance under the Aatmanirbhar Bharat initiative.
