51st Anniversary of the Submarines Arm of the Indian Navy.
08 Dec 1967– The Indian Flag was raised on India’s first Soviet-era Submarine at Riga. She was called INS Kalvari. Kalvari was a nascent start to a journey which saw dreamy eyed Indians entering the Submarine School to get the coveted Dolphin Badge on their chests. The 1967 Kalvari did its full service for the Nation and saw the Kilos, the HDWs and INS Chakra join the Indian Submarine fleet. Today, the Scorpene class INS Kalvari is back into Indian Waters and churns the seas along with indigenous nuclear Submarine INS Arihant and the new INS Chakra.
