INS Vindhyagiri was a Nilgiri-class frigate of the Indian Navy. Vindhyagiri was commissioned on 8 July 1981. After nearly thirty years of service, she sank a few hours after colliding with a German merchant vessel on 30 January 2011. Although she was subsequently salvaged, the navy decommissioned her on 11 June 2012, a year before her envisaged decommissioning date. Vindhyagiri served for 31 years, including a period as the flagship of the Western Naval Command.
