Sindhughosh-class submarines are Kilo-class diesel-electric submarines in active service with the Indian Navy. Their names are in Sanskrit, but in their Roman-alphabet forms sometimes a final short -a is dropped.

Contents

The Sindhughosh submarines, designated 877EKM, were designed as part of Project 877, and built under a contract between Rosvooruzhenie and the Ministry of Defence (India).

The submarines have a displacement of 3,000 tonnes, a maximum diving depth of 300 meters, top speed of 18 knots, and are able to operate solo for 45 days with a crew of 53. The final unit was the first to be equipped with the 3M-54 Klub (SS-N-27) antiship cruise missiles with a range of 220 km.

As of 2024, three of the submarines (S55, S57, S59) based at INS Vajrabahu, Mumbai, form 12th Submarine Squadron while four of the submarines (S60, S61, S62, S65) based at INS Virbahu, Mumbai, form 11th Submarine Squadron. [3]

Life extension and refit

INS Sindhuvijay has been upgraded with the hydro acoustical USHUS complex and the CCS-MK radio communications system. [4] On 29 August 2014, DAC cleared the long-awaited mid-life upgrade of the four Kilo-class submarines, which would be carried out in Indian shipyards and is likely to cost ₹ 4,800 crore (equivalent to ₹77 billionorUS$920 million in 2023). [5] On 5 November 2014 official sources at HSL said more than 90% of the work has been completed on the seventh submarine of the Sindhughosh class INS Sindhukirti. [6] Scheduled to re-join the fleet on 31 March 2015, she re-entered service on 23 May. [7] [8]

The Indian Navy signed a contract with the Russian shipbuilder Sevmash to refit and upgrade the existing submarines and to extend their operational life by 35 years. The first submarine, INS Sindhukesari, will be sent for refit starting June 2016. The extensive refit, the value for which is pegged at ₹ 5,000 crore (equivalent to ₹72 billionorUS$860 million in 2023) for a total of four submarines, will not only extend the life of the boats but will also upgrade their combat potential and fitted with Klub land attack cruise missile. [9] [10]

In 2015, the naval exercise Malabar, between the navies of India and the United States, involved Sindhudhvaj and USS City of Corpus Christi hunting each other. India Today reported that Sindhudhvaj managed to track Corpus Christi and score a simulated kill without being detected. [11]

In December 2015, L&T was chosen by the Russian shipbuilder Sevmash to be its Indian partner in the refit project. While the first of the four Kilo class subs will go to the Russian Zvezdochka shipyard for inspection and refit, the remaining three are likely to be modernized at the Kattupalli shipyard. The first of the submarines to be modernized at private yard, a first for India, will go in by 2017, An order for 2-3 more submarines could also be commissioned, depending on ongoing acquisition plans of the Indian Navy. [12] [13] [14]

One of the submarine was deployed alongside INS Vikrant along with 7 frontline warships and 5 submarines (Shishumar class and Kalvari class) on 7 November 2024. The operations included carrier operations of MiG-29K, missile firing drills, submarine manoeuvres and flypasts by 30 aircraft demonstrated to the President of India Droupadi Murmu who was present on board INS Vikrant.
