IS Karanj, India's third Scorpene class
submarine, was launched in Mumbai on Wednesday 31January 2018, according to an
submarine was launched at the Mazagon Dock Shipbuilders Ltd (MDL), and navy
chief Admiral Sunil Lanba was the chief guest.
Karanj was the third Scorpene class submarine
built by the Defense Ministry under the ambitious Project 75
scheme of the Indian Navy. In all, there will be six such submarines being
indigenously built but were designed by French naval defence and energy
company DCNS, and are being built in Mumbai.
The first of these, INS Kalvari, was commissioned
in Mumbai (link) last December. The second, INS Khanderi, is undergoing sea
trials. All submarines are due to be inducted gradually into the Indian Navy by
The ambitious plan incurred a massive Rs 3.5
billion cost for the Indian Navy. As per the original schedule, two of the
submarines were to be commissioned last year, but the project has fallen behind
The first four submarines will be conventional,
while the last two are to be equipped with the Air Independent Propulsion (AIP)
system, which will enable the vessel to stay underwater for longer duration.
All six diesel-electric attack submarines will be
equipped with an anti-ship missile, which has a proven record in combat,
besides other weapon systems.
The state-of-the-art features of the Scorpene
submarines include superior stealth and ability to launch crippling attacks
with precision-guided weapons.
The attacks can be carried out with torpedoes
both while submerged or on the surface — in all war theatres, including the
tropics, giving it an unmatched invulnerability.
The submarine has an overall length of 67.5
metres and height of about 12.3 metres. The hull form, fin and hydroplanes are
specifically designed to produce minimum underwater resistance.
Keeping with Indian naval tradition, INS Karanj
too is a reincarnation of an older submarine that was in operation from 1969 to
2003. It served the country for 34 years and was also part of operations in
1971. Wednesday's event marked the rebirth of the submarine in a new avatar,
