Duikbootprogramma India

Graphic News

June 24, 2019 -- Door veroudering van de huidige vloot duikboten, bouwt de Indiase marine 4 kernonderzeeërs geschikt voor uitrusting met ballistische raketten (SSBN) en zes dieselelektrische jachtduikboten van de Scorpène-klasse (SSK)

The Indian Navy (IN) commissioned four Shishumar Class SSKs and eight of the nine active Sindhughosh (Kilo) Class submarines between 1986 and 1994. The boats have received mid-life upgrades, but if the standard 30-year limit is respected, the subs will have to leave service by 2024.

Since the launch of its Advanced Technology Vessel (ATV) project in the 1990s, India has achieved its long-held goal to establish a nuclear deterrent across the land, air and sea -- the so-called “nuclear triad.”

“In an era such as this, a credible nuclear deterrent is the need of the hour,’ said Prime Minister Narendra Modi in November 2018, as he announced that India’s first SSBN, INS Arihant, had completed its first deterrent patrol armed with nuclear missiles.

The second Arihant-class SSBN, INS Arighat, launched in 2017, is currently undergoing sea trials.

In October 2005, India signed a contract for Project 75(I). Six Scorpène-class diesel-electric attack submarines (SSKs) were to be built by Mumbai-based Mazagon Dock Shipbuilders Limited (MDL) and partner, France’s Naval Group.

Construction of Boat 1 (Kalvari) began in May 2009, fabricated from 16 subsections. The hull fabrication of all six P75(I) submarines is now complete and four boats, INS Kalvari, Khanderi, Karanj and Vela, have been launched, the latter in May 2019. The IN commissioned Kalvari in December 2017.

The P75(I) project has not been without problems. In June, Jane’s Defence Weekly reported that the IN has refused to commission INS Khanderi until MDL and France’s Naval Group fix a total of 36 defects and deficiencies -- including “unacceptably high” engine and propeller noise levels.

Earlier, in August 2016, the leak of some 22,000 pages outlining classified capabilities of the Scorpènes roiled the government in New Delhi. Revelations included stealth details, noise levels, cavitation data and sonar frequencies and ranges.

Project 75(I) is currently estimated to cost between INR400 billion and INR450 billion -- US$5.75 billion and $6.47 billion.

NEW GRAPHIC NEWS - a new website for a new era, coming soon…

And it will be worth the wait! The Graphic News website is undergoing a complete redesign. The new site will not only see improvements in terms of speed and user experience, but will also include many new features. For example, existing subscribers will be able to manage their accounts online via a group dashboard, and add selected graphics to lists for project planning (and which can be shared across the group).

Existing users will need to register individually - we’ll be sending instructions to our main contacts at each group and will be on hand to help you through the process, which we hope will be seamless!
