Comments: All three vessels were built at Leningrad, Russia. These ships were the harbinger of the SAM era in the Indian Navy and constituted the 21st Missile Vessel Squadron (K21), based at Mumbai. Interestingly, while the Indian Navy has phased out these ships, the Algerian Navy completed a major refit of their Nanuchka Class corvettes with the 3M-24E AShM and the new Positiv ME1 3D radar.

The vessels derived their names from famous forts, with the Hosdurg being named after a historic fort in Kerala, which was built during the Ikkeri Dynasty by Somashekara Nayak. The Vijaydurg was named after the capital sea fort of Kanhoji Angre, Admiral of the Maratha Fleet. The Admiral was witness to numerous spirited sea battles in history against the Europeans. The Sindhudurg was named after a historic fort, of which for centuries was the bastion of Maratha maritime defense.

On her last deployment prior to her decommissioning on 05 June 1999, the Hosdurg could barely manage 13-14 knots because of her very poor material state. The decommissioning ceremony of the Hosdurg was conducted by Commander Handa, who served as her last Commanding Officer. She served for 21 years in the Navy. In June 2000, the Hosdurg was sunk off the west coast of India, by a Sea Eagle AShM fired from a Jaguar IM of the Indian Air Force.

The Vijaydurg was commissioned at Riga, Russia and on her arrival in India, joined the Western Fleet where she was extensively deployed for local naval defence. The Vijaydurg served for 25+ years and participated in two fleet reviews including the 2001 International Fleet Review at Mumbai. The chief guest at the decommissioning ceremony of the Vijaydurg was Vice Admiral R.B. Suri PVSM, AVSM, VSM (Retd.), who served as her first Commanding Officer.

The chief guest at the decommissioning ceremony of the Sindhudurg was Commodore I.J. Sharma (Retd.), who served as her first Commanding Officer. She was the first ship in the Indian Navy which shot down the P-15 (SS-N-2A Styx) anti-ship missile, during a naval exercise in the west coast heralding a new era of missile warfare. During her 27 years of service in the Navy, she spent about 3500 days at sea and covered more than 140,000 nautical miles, almost three times the earth's circumference. She also took part in three major exercises - Operation Brasstacks in 1986, Operation Vijay in 1999 and Operation Parakram in 2002. Commander Y.S. Tanwar served as her last Commanding Officer.
