Scorpene-Class submarinesState-owned Mazagon Dock Shipbuilders Ltd, India’s biggest warship builder delivered INS Khanderi, the second of the six Scorpene-Class submarines to the Indian Navy, at an event held in Mumbai.

  • The fully-automated submarine will be commissioned into the Indian Navy on September 28 at the Naval Dockyard by Union Defence Minister Rajnath Singh.


  • The submarine ‘KHANDERI’ is named after the wide snouted Sawfish, a deadly sea predator of the great Indian Ocean.
  • Its name also comes from its predecessor INS Khanderi (S22), a “Foxtrot” class submarine that was decommissioned in 1989, that was in turn named after Chhatrapati Shivaji’s island fort of Khanderi.
  • With the delivery of Khanderi, India further cements its position as a submarine building nation and MDL has lived up to its reputation as one of India’s leading shipyards with a capacity to meet the requirements of the Indian Navy.

●     The govt has cleared the P75I plan under the strategic partnership model.

●     P75I was first cleared in 2007 but lay dormant until now after undergoing numerous changes.

●     The P75I project is part of a 30-year submarine building plan that ends in 2030.

●     As part of this plan, India was to build 24 submarines — 18 conventional submarines and six nuclear-powered submarines (SSNs) — as an effective deterrent against China and Pakistan.

●     The Indian Navy’s Project 75I (P75I) Scorpene submarine development for six latest-generation diesel-electric attack boats is expected to be completed by 2022.

●     The P75I Scorpene-class air-independent propulsion (AIP) submarines are based on the Scorpene-class submarines, which were designed by French naval shipbuilding firm DCNS in partnership with Spanish shipbuilding firm Navantia.

●     The Indian Navy intends to use the submarines for missions such as area surveillance, intelligence gathering, anti-submarine warfare, anti-surface warfare, and minelaying operations.

●     The first submarine named INS Kalvari was commissioned into the Indian Navy last September.

●     The construction of third Scorpene INS Karanj was started on 31st January 2018 and is currently undergoing sea trials.

●     The fourth Scorpene, INS Vela was recently launched in May 2019 and is being prepared for sea trials.

●     The remaining two submarines, Vagir and Vagsheer are in various stages of outfitting.

●     Mazagon Dock is building the submarines under a transfer of technology agreement with the Naval Group of France, DCNS.

●     The Scorpene-class submarines have also been acquired by the naval forces of Chile, Malaysia, and Brazil.


ARIHANT class submarine

●     The Arihant class is a class of nuclear-powered ballistic missile submarines being built for the Indian Navy.

●     They were developed under the Advanced Technology Vessel (ATV) project to design and build nuclear-powered submarines.

●     Four submarines of this class have been planned.

●     The first, INS Arihant, was commissioned in August 2016.

●     The first four vessels are expected to be commissioned by 2023.

●     In December 2014, the work on a second nuclear reactor began and the second boat, INS Arighat /Ardhiman is being prepared for sea trials.

●     The final two ships S-4 and S-4* in the class will be larger than the previous two.

●     The Navy currently has 14 SSKs — nine Sindhughosh-class (Russian Kilo-class), four Shishumar-class (German Type 209) and one Kalvari-class (Scorpene-class) submarines.

●     Besides these, the navy also has one SSN, INS Chakra, a Russian Akula-class submarine taken on lease in 2012 for 12 years.

●     INS Arihant will be the first SSBN-type submarine in the Navy. It has also been reported that it’s sister vessel, the INS Aridhaman, is nearing completion.


PROJECT 28/KAMORTA class corvette

Scorpene-Class submarines

●     The Kamorta-class corvettes or Project 28 are a class of anti-submarine warfare corvettes currently in service with the Indian Navy.

●     Built at Garden Reach Shipbuilders & Engineers (GRSE), Kolkata, they are the first anti-submarine warfare stealth corvettes to be built in India.

●     Project 28 was approved in 2003.

●     Three of the four corvettes, INS Kamorta, INS Kadmatt, and INS Kiltan were commissioned in 2014, 2016 and 2017 respectively.

●     INS Kavaratti is under construction and slated to be completed by May 2019.

●     The platform and major internal systems of this class of corvettes are indigenously designed and built.

●     The corvettes are named after the islands in the Lakshadweep archipelago.
