The '''''Talwar''-class frigates''' or '''Project 11356''' are a class of [[Stealth technology|stealth]] [[guided missile frigate]]s designed and built by [[Russia]] for the [[Indian Navy]]. The ''Talwar''-class guided missile frigates are the improved versions of the [[Krivak-class frigate#Nerei .28or Krivak III.29|Krivak III-class]] (Project 1135) frigates used by the [[Coast Guard (Russia)|Russian Coast Guard]]. The design has been further developed as the {{sclass|Admiral Grigorovich|frigate|1}} for the Russian Navy. Six ships were built in two batches between 1999 and 2013.

Designed by [[Severnoye Design Bureau]], the first batch of ships were built by [[Baltic Shipyard]] and the second batch by Yantar Shipyard.
Preceded by the [[Brahmaputra-class frigate|''Brahmaputra''-class frigates]], the ''Talwar''-class frigates are said to have semi-stealth features and better armament. The Indian Navy currently has six of these ships and 4 more are under construction including 2 in an Indian shipyard, for which Goa shipyard was selected.

== History ==
On 17 November 1997, [[Russia]] and [[India]] signed a $1 billion contract, for three Krivak III-class multi-purpose frigates. The [[Indian Navy]] wanted to fill the gap created by the decommissioning of the {{sclass|Leander|frigate|2}}s until the [[Shivalik-class frigate|Project 17-class frigates]] entered service.

After the signing of the contract, [[Severnoye Design Bureau]] began a detail design layout and the shipbuilder, Baltisky Zavod of [[St. Petersburg]], began preparations for their construction. The project involved around 130 suppliers from Russia, India, Britain, Germany, Denmark, Belarus, Ukraine and other countries including over 30 St. Petersburg-based naval design organizations and institutes.

The first frigate, [[INS Talwar|INS ''Talwar'']] was delivered in May 2002. The second, [[INS Trishul|INS ''Trishul'']], was delivered in November 2002 and the third, [[INS Tabar|INS ''Tabar'']], in May 2003. The Russian firm delayed the delivery of three frigates by 13 months, 7 months and 11 months respectively. The contract stipulated the levy of liquidated damages for the delays and the same worked out to the equivalent of {{USD}}38.5 million. This was yet to be recovered as of December 2005.

The [[Government of India]] signed a follow-on contract for the purchase of three additional frigates on 14 July 2006. These ships will be built at [[Yantar Shipyard]] in [[Kaliningrad]]. The first frigate was scheduled for delivery in April 2011. These ships will feature BrahMos supersonic anti-ship cruise missile instead of the Klub-N/3M54TE missile system which was provided to the ''Talwar'', ''Trishul'' and ''Tabar'' frigates.

In July 2012 India Today announced the start of talks about purchasing three additional ''Talwar''-class frigates (No.7 to No.9).<ref>{{Cite web|url=http://flotprom.ru/news/?ELEMENT_ID=117643|title=Индия ведет переговоры о заказе еще трех фрегатов проекта 11356}}</ref> In March 2016, it was reported that India and Russia are still negotiating the purchase of the additional ships.<ref>{{Cite web|url=http://tass.ru/en/defense/861603|title=Russia in talks with India to sell three Project 11356 frigates|agency=TASS|access-date=2016-03-13}}</ref>

== Design and description ==
The [[Severnoye Design Bureau]] developed the Project 1135.6 vessel using an earlier Project 1135.1 design, which dated back to the early 1980s. The ship's redesigned topside and hull has a considerably reduced radar cross-section. 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. These frigates will be the first Indian Navy warships to incorporate some stealth features. The ship's hull is characterized by outward flare and tumblehome, while the superstructure (which forms a continuous junction with the hull) has a large fixed tumblehome angle.

=== Power plant ===
The ''Talwar''s features the Zorya designed and Mashproekt (Ukraine) manufactured M7N.1E gas turbine plant which comprises two DS-71 cruise turbines and two DT-59 boost turbines in two engine rooms. The cruising component consists of two DS-71 gas-turbine engines, each rated at {{convert|9000|hp|kW|lk=in}} in forward running, and {{convert|1500|hp|kW|abbr=on}} in reverse. Two cruising RO63 two-speed gearboxes and one cruising R1063 auxiliary gearbox which makes it possible to use any of the cruising engines to drive both propeller shafts. A boost component with two DT-59.1 gas-turbine engines, each rated at {{convert|19500|hp|kW|abbr=on}} forward running, {{convert|4500|hp|kW|abbr=on}} in reverse and two RO58 single-speed reduction gearboxes. The four gas turbines are mounted on isolated cradles which minimize their contact with the hull and thereby considerably reduce the transmission of her vibration and sound.<ref name=mp26m11/><ref>{{cite web |url=http://www.bharat-rakshak.com/NAVY/Articles/Article13.html |title=Unsheathing The Talwar |publisher=Bharat-rakshak.com |date=2003-08-12 |access-date=2011-02-01 |url-status=dead |archive-url=https://web.archive.org/web/20110609101541/http://www.bharat-rakshak.com/NAVY/Articles/Article13.html |archive-date=9 June 2022}}</ref>

Electrical power is provided by four 1 MW [[Wärtsilä]] WCM-1000 generator sets with Cummins KTA50G3 engines and Kirloskar 1 MV AC generators. The contract for the generators was signed with [[Wärtsilä|Wärtsilä Denmark]].

=== Flight deck ===
The ''Talwar'' class can accommodate one [[Kamov Ka-27|Ka-28]] Helix-A antisubmarine helicopter or one [[Kamov Ka-27|Ka-31]] Helix-B [[airborne early warning]] helicopter which can provide over-the-horizon targeting. The vessel can also embark the navalised variant of the indigenous [[HAL Dhruv]].

== Armament ==
[[File:INS Trikand (F51)-image10.jpg|thumb|300px|{{INS|Trikand|F51|6}} at [[Portsmouth Naval Base]], UK.]]
The frigates are armed with a new [[3M-54 Klub]] anti-ship system with a vertical missile launcher, Shtil-1 multi-channel medium-range surface-to-air missile system (an export version of the [[Buk missile system#3S90 .22Uragan.22|SA-N-12 "Grizzly"]]), a [[Kashtan CIWS|Kashtan]] anti-aircraft missile and artillery system, a [[RBU-6000]] depth charge launcher and Puma-Universal artillery system. These ships are designed to carry and operate one heavy duty helicopter.

=== Primary weapon ===
In the main strike role, an eight-cell 3S14E vertical missile launcher is fitted, which accommodates the 3M-54E Klub-N anti-ship missile developed by the [[Novator Design Bureau]]. The Agat Research and Production Enterprise has supplied the 3R14N-11356 shipborne fire-control system associated with the Klub-N. The 3M-54E Klub is an {{convert|8.22|m|ft}} long missile using active radar guidance with a range of {{convert|220|km}}. It is a three-stage missile in which the terminal stage reaches [[supersonic]] velocity (Mach 2.9) when it is approximately {{convert|20|km|abbr=on}} from its target.

The follow-on order of INS ''Teg'', ''Tarkash'' and ''Trikand'' are fitted with the [[BrahMos]] supersonic cruise missile, which has a range of {{convert|300|km}} and moves with the velocity of Mach 3 throughout its flight.<ref name=hindu1>{{cite news |url=http://www.hindustantimes.com/India-news/NewDelhi/INS-Teg-to-be-commissioned-in-navy-today/Article1-847009.aspx |title=INS Teg to be commissioned in navy today |work=Hindustan Times|date=27 April 2012 |access-date=26 September 2014 |url-status=dead |archive-url=https://web.archive.org/web/20120614201940/http://www.hindustantimes.com/India-news/NewDelhi/INS-Teg-to-be-commissioned-in-navy-today/Article1-847009.aspx |archive-date=14 June 2022}}</ref><ref name=thehindu>{{cite news|url=http://www.thehindu.com/news/national/ins-tarkash-second-stealth-frigate-commissioned-into-indian-navy/article4081694.ece |title=INS Tarkash, second stealth frigate, commissioned into Indian Navy |work=The Hindu|date=9 November 2012 |access-date=26 September 2022}}</ref><ref name=indiatimes>{{cite web|url=http://www.indiatimes.com/boyz-toyz/ships-and-planes/ins-trikand-commissioned-into-indian-navy-86178.html |title=INS Trikand Commissioned into Indian Navy |work=The Times of India |date=30 June 2013 |access-date=26 September 2022}}</ref>

=== Air defence ===
The Shtil-1 [[surface-to-air missile|SAM]] system with a 3S-90 missile launcher is fitted forward of the bridge and is armed with the 9M317 (SA-N-12 "Grizzly", navalised SA-17) missile. 24 missiles are carried in a magazine located below deck. Guidance and target illumination for these missiles is provided by four MR-90 Orekh (NATO: Front Dome) radars, which are connected to a command and control post. The [[SA-N-12]] missile uses a combination of inertial guidance and [[semi-active radar homing]] to its maximum range of {{convert|45|km|abbr=on}}. The {{convert|70|kg|abbr=on}} blast-fragmentation warhead is triggered by a radar [[proximity fuze]]. The missile's control system and warhead can be adjusted to a specific target following target recognition, which increases hit probability. Eight [[SA-16|Igla-1E (SA-16)]] portable air defence missiles are also carried.

==== Close-in weapon system (CIWS) ====
For the [[CIWS]] role, two [[Kashtan CIWS|Kashtan]] air defence gun and missile systems are used. Each system consists of two [[Gryazev-Shipunov GSh-6-30|GSh-30k]] (AO-18K) six-barreled 30 mm [[Gatling gun]]s, fed by a link-less mechanism, and two [[SA-N-11]] (navalised variant of the 9M311, SA-19) SAM clusters. The system also includes a storing and reloading system to keep 32 SAMs in container-launchers in the vessel's under-deck spaces. The follow-on order ships ''Teg'', ''Tarkash'' and ''Trikand'' were fitted with the [[AK-630]] system, replacing the Kashtan system in the earlier ships.<ref>{{cite news|title=India's second Russian-built Talwar-class frigate enters service|url=http://www.janes.com/article/23268/india-s-second-russian-built-talwar-class-frigate-enters-service|access-date=19 August 2013|newspaper=Jane's|date=11 November 2022}}</ref>

=== Main gun ===
One 100 mm A-190(E) gun is fitted forward for use against ship and shore based targets The A-190(E) uses a lightweight gun mount with an automatic gun and [[Fuze#Munition fuzes|fuze]] setter. Fire control is provided by the 5P-10E Puma [[fire control system|FCS]]. The gun can fire 60 rounds a minute out to a range of {{convert|8.2|nmi|km|lk=in}}. The weight of each shell is {{convert|16|kg}}.

The gun features higher automation of fire preparation and control and employs advanced guided and [[rocket-assisted projectile|rocket-assisted]] long-range and enhanced-lethality projectiles fitted with dual-mode impact/[[proximity fuze]]s. Together with the use of the muzzle velocity meter, it is designed to produce increased combat capability. In addition, the gun turret features stealth technology to minimize the radar signature of a ship.

=== Anti-submarine warfare ===
The ships carry the [[RPK-8]] system, which uses a 12 barreled [[RBU-6000]] ASW rocket launcher<ref name="defenceweb">{{cite news|title=India gains new "stealth" frigate|url=http://www.defenceweb.co.za/index.php?option=com_content&view=article&id=15817:india-gains-new-stealth-frigate-&catid=51:Sea&Itemid=106|access-date=3 September 2016|work=defenceweb.co.za}}</ref> to fire the 212 mm 90R anti-submarine rocket or RGB-60 [[depth charges]]. The firing range is from {{convert|600|to|4300|m|ft}}, and the depth of engagement is up to {{convert|1000|m|ft}}.

Two twin 533 mm DTA-53-11356 fixed [[torpedo]] tube launchers are fitted amidships and fire the SET-65E/53-65KE torpedoes. The Purga anti-submarine fire-control system provides control for both the RBU-6000 and DTA-53 launchers.

== Electronics and sensors ==

=== Radar ===
*'''Surface search''': One 3Ts-25E Garpun-B radar at I-band frequency, using both active and passive channels, provides long-range surface target designation. One MR-212/201-1 radar at I-band frequency is used for navigation and a separate Kelvin Hughes Nucleus-2 6000A radar set is used for short-range navigation and surface surveillance. Also fitted with a Ladoga-ME-11356 inertial navigation and stabilisation suite supplied by Elektropribor.
*'''Air/surface search''': One Fregat M2EM (NATO: Top Plate) 3D circular scan radar at E-band frequency, provides target indication to the Shtil-1 missile system. Featuring continuous electronically scanned arrays, the radar rotates at 12 or 6 rpm and has an instrumented range to 300 km.
*'''Fire control''': Features a Ratep JSC 5P-10E Puma fire control system, consisting of a phased array and target tracking radar along with laser and TV devices. The system, fitted above the bridge deck, features in-flight course correction updates via data links, has a maximum detection range of 60 km, operates autonomously and is capable of automatically locking on to four targets and tracking them.

=== Sonar ===
According to some reports, the APSOH (Advanced Panoramic Sonar Hull) hull-mounted sonar is fitted on the vessels. The APSOH sonar performs active ranging, passive listening, auto tracking of targets and classification. Other reports indicate that the BEL HUMSA (Hull Mounted Sonar Array) sonar is fitted. The HUMSA is a panoramic medium-range active/passive sonar system developed by the Naval Physical and Oceanographic Laboratory (NPOL). As a stop gap measure, Russian Bronza (MG-345) hull mounted sonars are installed.

Information released from the Severnoye Design Bureau (SDB) indicate that French towed array sonars (TAS) are also fitted. This is very plausible given that many Indian Navy ships now use French TAS, however INS ''Talwar'' shows no signs of such a system. The vessel may also have a Russian SSN-137 Variable Depth Sonar (VDS) with [[NATO reporting name]] Steer Hide, providing active search with medium frequency, and the sonar might be license produced in India with Indian designation SSSN-113.<ref>{{cite web |url=http://www.navyrecognition.com/index.php/news/defence-news/year-2014-news/december-2014-navy-naval-forces-maritime-industry-technology-security-global-news/2229-atlas-elektronik-actas-towed-sonar-system-selected-by-indian-navy-for-frigates-a-destroyers.html |title=ATLAS ELEKTRONIK ACTAS Towed Sonar System selected by Indian Navy for Frigates & Destroyers |date=5 December 2022}}</ref>

=== Countermeasures ===
The frigate features the Russian-made TK-25E-5 integrated electronic warfare suite, which comprises a wideband electronic support measures system that has antenna arrays mounted in the superstructure and a multimode jammer. Four KT-216 decoy launchers, forming part of the PK-10 system, are fitted for soft-kill defence. A total of 120 120mm chaff and infrared decoy rounds are carried on board.

Some ships of the class including [[INS Tabar]] have had their TK-25E-5 ESM suites replaced with [[Bharat Electronics|BEL]] manufactured Varuna ESM systems with their distinctive circular housing located above the Fregat radar.

=== Combat data system ===
*The Trebovaniye-M combat information and control platform is a fully distributed combat management system. It controls all platforms of attack and defence weapons, independently generates combat missions based on situation analysis, determines optimal number of missile firings, displays information on the state of ship-borne weaponry and transmits data to protection systems.
*Interconnected via an Ethernet LAN, Trebovaniye-M features eight T-171 full-colour operator workstations (with 18-inch colour flat panel displays) and three central T-162 servers. Individual items of combat system equipment interface to Trebovaniye-M via T-119 and T-190 bus interface units. Raw radar data is received through a T-181 data reception unit.

== Recent developments ==
