Indian Submarines and Naval Ships for UPSC Exam

Project 75 India

  • 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.
  • The project cost is about Rs. 45,000 crore.
  • 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.
  • This project envisages the construction of six conventional submarines with better sensors and weapons and the Air Independent Propulsion System (AIP).
  • The project has been cleared under the strategic partnership model.

Background

  • In 1999, the Cabinet Committee on Security had approved a ‘30-Year Plan for Indigenous Submarine Construction’. It was to develop two production lines on which six submarines would be built each named Project 75 and Project 75 (I) with foreign submarine makers.
  • These two projects will replace ageing Sindhughosh and Shishumar class submarines of Indian Navy, which numbered around 13.
  • The submarines in the P75 Scorpene-Class are powered by the conventional diesel-electric propulsion system.
  • The first Scorpene submarine, Kalvari, was commissioned in 2017 and it would go for a normal refit after six years in 2023, during which time the Air-Independent Propulsion (AIP) would be installed.
  • AIP technology is being developed by the Defence Research and Development Organisation (DRDO) to provide submarines long-range and extended endurance capabilities undersea.
  • Second Scorpene Khanderi was inducted in September 2019.

The third Scorpene submarine, Karanj, will be delivered to the Indian Navy by December 2020.
 

  • The remaining submarines (Vela, Vagir, and Vagsheer) in the series are in advanced stages of manufacturing and trials.

Air-independent propulsion (AIP)

  • AIP is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen.
  • It can augment or replace the diesel-electric propulsion system of non-nuclear vessels.

PROJECT 28

  • P 28 is a project under which four Anti Submarine Warships have to be built indigenously in India by Garden Reach Shipbuilders And Engineers (GRSE) , Kolkata.
  • Project 28 was approved in 2003, with construction of the lead ship, INS Kamorta commencing on 12 August 2005.
  •  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 end of 2017.
  • The warships are named after the islands in the Lakshadweep archipelago.
  • The Kamorta class corvettes are intended to succeed the Kora-class corvette by precedence and Abhay-class corvette by role.
  • Project 28’s objective was to enhance localization and development of warship construction industry in India.

Project 15B

  • Project 15B is a class of stealth guided missile destroyers currently under construction for the Indian Navy.
  • It is also known as the Visakhapatnam class.

The class comprises four ships

  • INS Visakhapatnam
  • INS Mormugao
  • INS Imphal
  • INS Porbandar
     
  • All of the destroyers are being built by the Mazagon Dock Limited (MDL) in Mumbai.
  • These ships have been designed indigenously by the Indian Navy’s Directorate of Naval Design, New Delhi.
  • The destroyers are an improved version of the Kolkata-class (Project 15A) and will feature enhanced stealth characteristics.


Features

  • The P15B destroyers incorporate new design concepts for improved survivability, sea keeping, stealth and manoeuvrability.
  • Enhanced stealth features and use of radar transparent deck fittings which make these ships difficult to detect.

Akula Class – Attack Submarine

Types

  • Conventional Submarines: These are the ones which are powered by electric motors and batteries.
    E.g. Project-75 Class Submarines
  • Nuclear Powered Ballistic Submarines: These are powered by nuclear fuel, thereby capable of operating underwater for longer durations. Primary role of such submarines is to provide strategic deterrence.
    E.g. INS Arihant
  • Nuclear Powered and Armed Submarines (SSN): These marines have unlimited endurance and high speeds and are armed with cruise missiles and heavyweight torpedoes, thus complementing carrier battle groups.
    E.g. Akula Class Submarines.

Akula Class Submarines

  • The Akula Class Submarine uses a nuclear reactor for propulsion, allowing it to remain underwater for an extended period of time which makes its detection impossible.
  • This class of Submarine can be used for multiple tasks like hunting enemy submarines, intelligence surveillance etc.

INS Chakra

  • INS Chakra is a Russia-made, nuclear-propelled, hunter-killer akula class submarine.
  • INS Chakra is one of the quietest nuclear submarines around, with noise levels next to zero.

  • The INS Chakra joined the Eastern Naval Command at Visakhapatnam in 2012.

INS Arihant

  • INS Arihant is the first of five nuclear missile submarines planned for induction.
  • It is to be equipped with K 15 (or BO-5) shortrange missiles with a range of over 700 km and the K 4 ballistic missile with a range of 3,500 km.
  • At present, the only nuclear – powered platform in service is the INS Chakra, a Akula class SSN on lease from Russia.
  • The induction of INS Arihant marks the completion of India’s nuclear triad.
  • A nuclear triad refers to the nuclear weapons delivery via land, air and sea i.e. land-based intercontinental ballistic missiles (ICBMs), strategic bombers, and submarine-launched ballistic missiles (SLBMs).
