INS Khanderi’s legacy lives on: exploring the general characteristics of a naval icon

From 1968 to 1989, INS Khanderi, a powerful diesel-electric submarine of the Kalvari class, rendered distinguished service to the Indian Navy. Presently on display at the Virbahu parade grounds, its complete fin serves as a moving reminder of its historical significance. Taking its name from Shivaji’s island stronghold, it was a symbol of bravery with exceptional mobility, range, and firepower.

A powerful diesel-electric submarine of the Kalvari class, INS Khanderi (S22) was an essential component of the Indian Navy. Built at Admiralty Shipyard Sudomekh, the ship joined the fleet in December 1968, strengthening the country’s nautical power. However, in 1989, INS Khanderi bid farewell to active duty following more than 20 years of devoted service.

After decommissioning, the submarine’s hull was scrapped, which is what happens to retired naval ships. The intact fin, which is currently on exhibit at the Virbahu parade grounds, is a poignant remain that has survived the destruction of the main structure. This moving act is evidence of the submarine’s historical significance and value to the Indian Navy.

Particularly, the name INS Khanderi was inspired by the famous island fort of Khanderi, which is located in the maritime domain connected to the Maratha monarch Shivaji. The submarine’s name honours a rich legacy by connecting the contemporary naval force to the legendary past of Shivaji’s island fortress and encapsulating the spirit of valour and historical significance.

INS Khanderi’s mobility is impressive since it can reach speeds of 16 knots while surfaced and 15 knots when submerged, demonstrating its versatility in a range of operational situations. Its remarkable range—20,000 miles at 8 mph when surfaced, and 380 miles at 10 knots when submerged—further highlights its potential.

The submarine’s test depth of 250 metres is a feature that highlights its capability to function well at considerable depths. With 75 crew members, including 8 officers, INS Khanderi is evidence of the teamwork needed for a successful operation.
