INS Sindhukirti (S61) is the seventh Sindhughosh-class diesel-electric submarine of the Indian Navy. She was built at the Admiralty Shipyard and Sevmash in the Soviet Union.

Sindukirti was commissioned on 04 January 1990, in erstwhile Soviet Union under the command of Cdr. Ramdas who signed her commissioning orders. She underwent a "medium refit" from June 2006 until May 2015 at the Hindustan Shipyard at Visakhapatnam. The midlife upgrade was projected to be completed in 3 years but numerous delays postponed the submarine's return.[3] Having spent one third of her lifetime in refits, she finally returned to service on 23 May 2015.[4]

Description

Sindhukiriti has a length of 72.6 m (238 ft) overall, a beam of 9.9 m (32 ft) and a draft of 6.5 m (21 ft). She displaces 2,300 t (2,264 long tons) surfaced, 3,100 t (3,051 long tons) submerged and has a maximum diving depth of 300 m (980 ft). The complement is about 68, including 7 officers and 61 sailors.[5][6]

The submarine has a shaft with one seven-blade propeller. It is powered by two diesel generators, each of which produce 1,000 kW (1,300 hp). It also has an electric motor with 5,500–6,800 hp (4,100–5,100 kW) of power. She can achieve a maximum speed of 10–12 knots (19–22 km/h) when on surface and 17–25 knots (31–46 km/h) when submerged.[5]

Operational service and refit

INS Sindhukirti was commissioned on 04 January 1990, by Cdr. Kannan Ramdas. She is the seventh of the ten Sindhughosh-class submarines.[5]

Midlife Medium refit

Sindhukirti was docked at Hindustan Shipyard in June 2006 for a midlife refit which included installation of USHUS sonar and the Klub-S cruise missiles and other hull works. She was originally planned to be sent to Russia for the upgrade but it was later decided for an indigenous upgrade. Hindustan Yard with almost zero experience in the field was chosen due to political wrangling against the wishes of the navy staff.[7][8][9][10]

Described by IBNLive as the dry dock queen, the mid-life upgrade initially projected to be completed in 3 years has seen numerous delays and will now probably finish only by March 2015.[9] In 2009, Admiral Sureesh Mehta said "That kind of expertise did not exist in India before and this is for the first time that we are trying it out here. Instead of sending them to Russia all the way, this one is being offloaded to Hindustan Shipyards. There are some problems in their procurement procedures. It takes a little longer than is expected".[8]

However, it was earlier reported that the poor workmanship of the shipyard has rendered the boat unfixable.[5] By 2009, she had spent ten out of her thirty years of service life in refits.[8] Official sources at HSL said more than 90% of the work has been completed[11][12]

After nine years in refit, Sindhukirti returned to sea on 23 May 2015 and is currently undergoing sea trials.[13][4]
