is India’s first Scorpene-class submarine and will be commissioned into the
Indian Navy by PM Narendra Modi today 14 December 2017.
The INS Kalvari is a diesel-electric
attack submarine that has been built for the Indian Navy by the Mazagon Dock
Shipbuilders Limited. It is the first of six such submarines that will be
inducted into the Indian Navy, and represents a significant success for the
"Make in India" initiative. The project has been undertaken with
INS Kalvari, according to the Ministry of
Defence, has the capability of undertaking offensive operations “spanning the
entire spectrum of maritime warfare”. And it will be a timely addition to the
Indian Navy when the ties with China and Pakistan are under pressure.
Kalvari is named after the dreaded Tiger Shark, a deadly deep
sea predator of the Indian Ocean.
is 67.5 metres long and has a height of 12.3 metres. The submarine “embodies
cutting-edge technology and compares favourably with the best in the world”.
“The hull form, the fin and the hydroplanes are specifically designed to
produce minimum underwater resistance. The 360 battery cells (each weighing 750
kg) power the extremely silent permanently magnetised propulsion motor. The
stealth is further enhanced through the mounting of equipment inside the
pressure hull on shock absorbing cradles,” says the Ministry of Defence.
Equipped with 18
torpedoes and with a capacity to travel 1,020 km underwater, it can dive to a
depth of 300 metres to effectively avoid
detection by the enemies. With precision-guided weapons, it can launch a deadly
attack with torpedoes and tube-launched anti-ship missiles underwater or even
from the surface. This
Scorpene submarine is designed to operate in all theatres of war, including the
tropics. Kalvari is capable of handling various missions such as anti-surface
warfare (attacking surface ships), anti-submarine warfare (destroying
submarines), intelligence gathering, mine-laying and area surveillance.
“The submarine’s attack and search periscopes
are equipped with infrared/low light level cameras and laser range finders.
Kalvari has two 1250 kW MAN diesel engines for rapidly charging batteries. The
submarine boasts of a highly advanced combat management system and a
sophisticated integrated platform management system,” adds the Ministry of
Defence. The submarine’s crest depicts a Kalvari, which is a tiger shark in
Malayalam. The submarine’s motto is “Ever Onward”.
was built with a special
kind of high-tensile steel that is capable of withstanding high yield stress.
This feature allows it to withstand pressure exerted by water, hydrostatic
force, while diving deeper to enhance stealth.
It is also capable of carrying weapons that can be easily reloaded
undergone extensive sea-trials over the past year-and-a-half and has
successfully test-fired anti-ship missiles and torpedos. These precision-strike
weapons give Kalvari and as a result the Indian Navy, a tactical advantage and
leg-up in the Indian Ocean region. All six ‘Make in India’ Scorpene-class
submarines will be equipped with torpedos and anti-ship missiles that have a
proven track record in combat. According to the Indian Navy, the missiles will
provide INS Kalvari with the “ability to neutralise surface threats at extended
At a time
when Indian Navy is down to a dozen submarines, the importance of Kalvari’s
commissioning cannot be understated. The Kalvari, having been manufactured in
India under Project 75, also gives the defence industry the capability of
building more advanced submarines in the future.
