New Delhi, June 21: In a landmark moment for India’s maritime preparedness and indigenous defence capability, Prime Minister Shri Narendra Modi on Sunday commissioned three frontline platforms - INS Dunagiri, an advanced stealth frigate; INS Sanshodhak, a survey vessel (large); and INS Agray, an anti-submarine warfare shallow water craft - into the Indian Navy in Kolkata. These state-of-the-art platforms will significantly enhance the nation’s operational capabilities, maritime security against geopolitical threats, and domain awareness. Addressing the gathering, the Prime Minister noted that the occasion coincides with the International Day of Yoga being celebrated across the world and expressed happiness at having the opportunity to visit the historic land of Bengal, which has played a pivotal role in shaping India's intellectual, cultural and national renaissance and has connected India with the world through maritime routes for centuries.
