New Delhi, 24
with latest AA, SSM, Sonar and weapon systems for self-protection
the Indian Navy’s latest stealth ship was commissioned on 18th
June, which will go down as a Sea Mark day in its history. A ship
that can compete with the best in the world is now the latest bride
of the Indian Navy. The second ship in the series, INS
Trishul will be commissioned on 25th June by Vice Admiral Arun
Prakash, FOC-in-C West and INS Tabar, the third of class, will be
commissioned in Ocotober, 2003 augmenting India's Fleet potential
immensely especially with Missile power and AA defence.
Admirals of the Indian Navy decided some years ago that a programme
to build/acquire ships for the 21st Century was needed to drive the
Indian Navy into the technological era, just as the Leander and HDW
Submarine programmes had been drivers of Indian Industry in the 70s.
We recall that in 1974 the First Sea Lord of UK visited Bombay and
went to sea in INS Nilgiri. He could not believe the ship with its
Seacat AA missile, was so exceptionally built for the navy by
the Mazagon Dock.
the HDW scandal derailed the submarine programme, and funds for the
Navy in the 80s slowed down. When INS Nilgiri the first of
class was commissioned, the Captain D S Paintal, had insisted that
every system on board be proved by the Shipyard. Ag LCdr Madhvendra
Singh was then the Gunnery Officer. In the case of TALWAR, the latest
Vertical Launch vessel, the same Admiral Madhvendra Singh and his
team of Admirals insisted that the Shtil long range AA and SAM
system be fully proved.
congratulate Captain S Soni and all who sail on the new Talwar fair
winds and following seas. Madhvendra Singh as a Commander was
the Captain of INS Talwar and it was retrofitted with surface-to-surface
Styx missiles from the OSA class boats that attacked Karachi. That
was another revolutionary experiment, emulated on INS Trishul. We
predict that the experience and technology will boost the Type 17
Project at Mazagon Dock for the future and India can look to exports
if the PJ 10 Brahmos missile succeeds.

'stealthy' ships are to a modified Krivak design based on on the
Severnoye (Northern) Design Bureau initiative. While the
superstructure sides are sloped and relatively clean, the very
cluttered topside of the ship cannot be remotely described as having
any signature reducing features. However, these frigates will be the
first Indian Navy warships to incorporate some stealth features and
a vertical launch missile system. Some weapon, radar and sonar
system details are still speculative.

Some reports indicate that Bharat APSOH, a hull-mounted, providing
active search & attack with medium frequency is installed. Also has a SSN-137 VDS (Variable Depth Sonar), providing active search

the air defence role, the Shtil-1 medium-range SAM with a single 3S-90
launcher is fitted forward of the bridge. The Shtil system uses
either the SA-N-7 (navalised SA-11) or the SA-N-12 (navalised SA-17)
surface-to-air missile, of which 24 missiles are carried on board.
Guidance and target illumination for these missiles is provided by
four MR-90 Orekh (NATO: Front Dome) radars. Eight Igla-1E (SA-16)
portable air defence missiles are also carried.
100mm A-190(E) gun, for use against ship and shore based targets,
with 60 rds/min to 8.2n miles; 15 km. Weight of shell is 16 kg. Fire
control is by the 5P10 director mounted atop the bridge. For the
CIWS (Close In Weapon System) role, two Kashtan Air Defence Gun/Missile Systems are used.
A-190(E) gun is based on innovative technological and layout
solutions, which features relatively low weight-size
characteristics. The gun leads to a more than three-fold increase in
the combat effectiveness of surface combatants, as compared to those
fitted with the AK-176M (fitted in the Khukri Class), owing to:
increase in the range of fire (roughly twofold); 1.8 times growth in
the lethality of projectiles at a target; doubled accuracy of fire;
and reduced reaction time as a result of automated operations, such
as preparation of the gun for firing, selection of ammunition,
monitoring of mechanisms' operation during firing, and display of
data on the operator's monitor.
A-190(E) gun is also superior to the AK-100 gun (fitted in the Delhi
Class) in terms of basic performance characteristics: the rate of
fire (approximately 1.5 times); accuracy (about three times);
weight; dimensions; and operating characteristics. The gun also
features higher automation of fire preparation and control. The gun
employs advanced guided and rocket-assisted long-range and
enhanced-lethality projectiles fitted with dual-mode impact /
proximity fuses set to operate over the target area. Together with
the use of the muzzle velocity meter, it is designed to produce ever
increased combat capability of the system in fire against sea- and
shore-based point and area targets. In addition, the gun hull
features stealth technology to minimize the radar signature of a
system using a 12 barrelled RBU-6000
ASW launcher to fire the 90R anti-submarine missile. The firing
range is from 600 to 4300 metres, and the depth of engagement is up
to 1000 metres.

November 1997, Russia and India signed a $1 billion contract, after
which Severnoye Design Bureau began detail design and the
shipbuilder, Baltisky Zavod of St. Petersburg, Russia began
preparations for their construction. The Talwar Class of vessels are
built as frigates, but because of the local area-defence Shtil-1 SAM
being installed on the Indian vessels, they will be designated as
destroyers in the Indian Navy.
first vessel, the Talwar, commenced engine sea trials in November
2001 and immediately ran into major problems with the machinery,
hull, equipment integration and weapons systems. Indian media
reports indicate that as of December 2002, the Shtil SAM system had
been unable to hit any airborne targets during trial firings. This
may be due to integration problems between the combat management and
weapons systems. The Indian Navy will not take delivery until all
problems are rectified. In fact, the commissioning crew was flown
back to India because of the extent of problems, and the time needed
to fix them. This has set back scheduled delivery dates very
considerably - from May 2002 for the Talwar to sometime around April
This project involves around 130 suppliers from
Russia, Belarus, Ukraine, India, Britain, Germany, Denmark and other
countries including over 30 St. Petersburg-based naval design
organizations and institutes. There are also a considerable number
of Indian component suppliers. Two Halmatic Pacific 22 Mk.I rigid
inflatable boats (RIBs) are used as general ships boats. The Talwar
Class of vessels are designed primarily for ASW warfare and for the
air defense of naval task forces. The Navy wants to fill the gap
created by the decommissioning of the Leander Class frigates and
until the Project 17 Class frigates enter service. These frigates
will be the first Indian Navy warships to incorporate some stealth
