  • INS Talvar- One ship Navy



    The ship's redesigned topside & hull has considerably reduced radar cross-section and this feature alone, clearly separates the Project 1135.6 from its predecessors. 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. The ship's hull is characterised by outward flare and tumblehome, while the superstructure (which forms a continuous junction with the hull) has a large fixed tumblehome angle.

    Displacement: 3850 tons full load.

    Dimensions: Length - 124.5 metres.
    .................Beam - 15.2 metres.
    .................Draught - 4.2 metres.


    Maximum Speed: 30 knots.

    Maximum Range: 4600 miles at 20 knots.
    .......................1600 miles at 30 knots.

    Maximum Sea Endurance: 30 days.

    Complement: 180 (incl. 18 officers)

    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, comprising 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: Some reports indicate that the BEL 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).

    Information released from the Severnoye Design Bureau indicate that French towed array sonars (TAS) are 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 SSN-137 VDS (Variable Depth Sonar), providing active search with medium frequency.

    Weapons: In the main strike role, an eight-cell KBSM 3S14E vertical missile launcher is fitted, which accommodates the Klub-N ASCM. The Agat Research and Production Enterprise has supplied the 3R14N-11356 shipborne fire-control system associated with Klub-N.

    In the air defence role, a single 3S-90 missile launcher is fitted forward of the bridge and is armed with the Shtil-1 SAM system. The system comprises of the 9M317 (SA-N-11, navalised SA-17) missile and 24 such missiles are carried in a below-decks magazine. 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.

    Manufactured by the Dolgoprudny Research and Production Enterprise, the 9M317 missile uses a combination of inertial guidance and semi-active radar homing (the 70 kg blast fragmentation warhead is triggered by a radar proximity fuze) to its maximum range of 45 km. The missile can engage the following targets irrespective of the intensive jamming and minimal altitude; tactical ballistic missiles; aircraft manoeuvring at acceleration up to 12 g; cruise and antiradar missiles; helicopter gun ships; remotely piloted aircraft; anti-ship missiles; and radar-contrast water-borne and ground targets. The missile's control system and warhead can be adjusted to a specific target (ballistic, aerodynamic, small-size, water-borne, ground, helicopter) following target recognition, which increases hit probability. Eight Igla-1E (SA-16) portable air defence missiles are also carried.

    One 100mm A-190(E) gun, for use against ship and shore based targets, is fitted forward. The A-190(E) uses a lightweight gun mount with an automatic gun and fuze setter. The mounting is fed from separate port and starboard magazines and uses three different rounds: a high-explosive shell with an impact fuze; an anti-aircraft shell using an electronic fuze; and an inert practice round. An automatic control and monitoring system prepares the gun for firing, selects the appropriate ammunition, conducts continuous diagnostics and computes firing corrections. Fire control is provided by the 5P-10E Puma FCS. The gun can fire 60 rounds a minute out to a range of 8.2n miles; 15 km. Weight of each shell is at 16 kg.

    The 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.

    The 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 and 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 ship.

    For the CIWS (Close In Weapon System) role, two Kashtan Air Defence Gun/Missile Systems are used.

    Features the RPK-8 system, which uses a 12 barrelled RBU-6000 ASW launcher to fire the 212mm 90R anti-submarine missile or RGB-60 depth charges. The firing range is from 600 to 4300 metres, and the depth of engagement is up to 1000 metres. Two twin 533mm 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 - a product of the Granit Central Scientific Institute - provides control for both the RBU-6000 and DTA-53 launchers.

    Combat Data System: The Trebovaniye-M combat information and control platform is a is a fully distributed combat management system produced by the Meridian Research and Production Enterprise JSC. 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-series bus interface units. Raw radar is received through a T-181 data reception unit. According to the Meridian Research and Production Enterprise, Trebovaniye-M hardware is based on ruggedised industry-standard processing boards supplied by Octagon Systems. Applications are coded in C++, running under the QNX real-time operating system.

    Helicopter Capacity: One Ka-28 Helix-A ASW helicopter or one Ka-31 Helix-B AEW helicopter. The vessel can also embark the navalised variant of the indigenous HAL Dhruv.

    Countermeasures: The Type 1135.6 frigate features the Russian-made TK-25E-5 integrated electronic warfare suite, which comprises of 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. A local ESM system featuring the BEL Ajanta system could also be on board.

    Now it lacks a Passive radar for ASW.

    Which are the western equivalents?
    FIDSNS

    The OHP of the USN(and many others), the Duke FFG of the RN and the F100 Aegis of Spain.

    The F100 is easily the most powerful vessel of the lot.
