with eight 9M-311 Grison missiles (NATO: SA-N-11) with a range of . There are 64 Grison reloads (32 each mount) with a package of four missile taking less than two minutes to load. Forward of INS Tabars bridge and aft of the VLS is one 12-round RBU-6000 anti-submarine warfare rocket launch that can fire either Splav-90R rockets or RGB-60 depth charges. Two pairs of fixed DTA-53 torpedo tubes are located port and starboard midships. Both can launch either SET-65E anti-sub and 53-65KE anti-ship torpedoes. Sensors Controlling this array of weapons is the Trebovaniye-M combat information and control system that can control all of INS Tabars weapons as well as using situation analysis to generate combat missions. The combat system can transmit data and process information from up to 250 sources. With a range of nearly , the Fregat M2EM (NATO: Top Plate) 3D radar is INS Tabars air/surface radar. The M2EM system features continuous scanned arrays along with providing targeting information for the Shtil-1 missile system. One 3Ts-25E Garpun-B radar unit is utilised for long-range surface search and target acquisition. INS Tabar is also equipped with two navigation radars. INS Tabars fire control is the Ratep JSC 5P-10E Puma fire control system. The Puma uses phased array and target tracking radar along with laser and TV devices. The Puma can operate autonomously with the ability of automatically detecting, locking on, and tracking four targets at once. INS Tabars sonar is the BEL APSOH (Advanced Panoramic Sonar Hull) hull-mounted sonar. The APSOH sonar has active ranging, passive listening, and auto tracking of targets. For countermeasures INS Tabar includes chaff and infra-red decoy rounds fired by four KT-216 launchers. This ship was originally equipped with the Russian TK-25E-5 electronic warfare suite and was later replaced by the BEL manufactured Varuna ESM/Electronic warfare suite with its distinctive circular housing located above the Fregat radar. Air operations For her deployment INS Tabar had a Ka-31 Helix-B AEW helicopter embarked from Indian Naval Air Squadron 339 ‘Falcons’ Squadron in Mumbai. With a flight crew of two, the Ka-31 has a speed of and a maximum ceiling of 6,000 metres. Its range is a maximum of and can remain airborne for 4.5 hours. The Ka-31’s airborne early warning radar is the E-801M Oko (Eye), a planar array located beneath the fuselage. The radar unfolds during flight and has the ability to detect up to 200 targets
