India is Now Among The Few Countries Where Ships and Submarines Are Made Indigenously.

  • Defence Minister Rajnath Singh today commissioned the indigenously built Kalvari class diesel-electric submarine INS Khanderi possessing superior stealth and other major combat capabilities in Mumbai. After that he launched the warship Nilgiri, which is the first ship of Project 17A here, and said that launching the first of such stealth frigates has brought him immense pride and satisfaction for the defence capabilities of the country.
  • India is a large country and has vast maritime potential. We have around 7500 kilometers of the coastal area. A small disruption can damage our large interest that's the reason why we are giving so much importance to the Indian Navy," Singh said at the launch event of Nilgiri here.
  • India is now among the few countries where ships and submarines are made indigenously. Our target is to make India a country of USD 5 trillion economy. Our target for 2027 is that 70% of defence production should be indigenous," Singh said.
  • Nilgiri: The stealth frigate, Nilgiri, is made with the co-ordination of Mazagon Dockyard Limited and Garden Reach Shipbuilders and Engineers with the Indian Navy, DRDO, and other public and private partners.

  • The launch of the first ship of Project 17A marks another significant milestone in the annals of the indigenous warship design and construction program of India.
  • INS Khanderi: With intent to achieve supremacy by way of increasing underwater presence in the Indian Ocean Region (IOR) with various sea-based threat perceptions evolving in the region, the Indian Navy had taken up the production of six Kalvari class (Scorpene) diesel-electric attack submarines (SSKs) under Project 75 (P-75). And are being constructed with the support and technology transfer (TOT) from French company Naval Group (former DCNS) at the Mazagon Dock Limited (MDL).
  •  Fully automated submarine INS Khanderi is built at state-run Mazgaon Dock Limited and underwent rigorous sea trials for over two and a half years. Key features of the submarine include a state-of-the-art stealth technology which reduces its noise under the sea. Another crucial feature of the new submarine is that unlike previous requirement of 60 crew, its maximum requirement is 36 crew. It saves oxygen availability and increases its capacity to stay underwater for long periods.
  • Scorpene submarines boast of a large payload of heavy weaponry, integrated with hi-tech electronic sensors and weapons through Integrated Combat System. It is understood that Scorpene-class submarines are armed with six torpedo launching tubes and precision-guided weapons. To support the Weapons and Navigation systems, various sonars are fitted onboard (viz. Bow sonar, Stern sonar, Side looking sonars, Towed array active sonar) for identifying the threats, including mines, in shallow and deep waters. The inputs from the Sonar suite are utilized in the Torpedo Fire Control computers for various attacks/counter-attacks measures. For above water Target detection, the submarine uses surveillance radar (when it is operating on sea surface level).
  • Exocet SM-39 Anti-ship Missiles: A top naval officer has indicated that the French EXOCET tube-launched MBDA SM-39 anti-ship missiles are fitted as an integral package onboard the Kalvari Class submarines. These are the submarine variant of Ship launched SSMs. Each is 4.69 m long SM-39 missile weighs approx. 655kg and has a 350mm diameter. The missile is housed in a water-tight capsule, which is launched from the submarine’s standard torpedo tube and has a two-stage solid propellant. 
  • Air-independent Propulsion (AIP): With an AIP system, a submarine can run its propulsion electric motor and other electrical systems bypassing the use of conventional batteries, thereby, allowing the submarine to remain submerged for a longer duration (by reducing the need to surface often to take in the air for running diesel engines for charging batteries).
  • The Kalvari class submarine has the provision for fitment of AIP to achieve better capabilities; however, the AIP system to be indigenously developed by DRDO has been delayed. With the status of on-going progress made by DRDO, the AIP system on the submarine looks available for integration only by next scheduled major overhaul period of the submarines, which could be after six years or so.
