INS MYSORE



INS Mysore is the second in a series of three 6700+ tons indian built project 15 delhi Class multi-purpose destroyers performing anti-ship, anti-air and anti-submarine roles. With a length of 534.8 feet, a beam of 55.8 feet and a draught of 21.3 feet, these are the most powerful surface combatants to fly the Indian Naval ensign and are well suited for power projection roles in the Indian Ocean Region. Fully fitted with flag facilities, the Mysore and her sister ships primarily act as command and control platforms for task groups and as screening escorts for the aircraft carrier INS Viraat.

INS MYSORE

It is built by the state-owned shipyard Mazagon Dockyard Ltd (MDL) in mumbai at a cost of approximately $250-300 million each, the three ships are the largest indigenously built surface combatants. The costs for similar warships built elsewhere would easily exceed $500 million a unit. The most unique feature of these hybrid vessels is the integration of Russian, Western and Indian weapons systems & equipment. Featuring an indigenous component of roughly 60%, their armament and propulsion system is largely of Russian or Ukrainian origin while most of the sensors, electronics and other equipment are of Western or Indian origin. Keeping in mind that the basic design dates from the early 1980s, stealth features are minimal. INS Mysore has some differences from INS Delhi. Most noticeably, the massive blast shields behind the missile launchers are gone and there are minor improvements over INS Delhi. The Russian influence is very evident as the ship bristles with all manner of sensors, armament and missile launchers in atypically Russian fashion. One wonders if mutual electronic interference is a problem when all these sensors are operating simultaneously.

The missiles are housed in four quadruple KT-184 launchers angled at 30 degrees, two on either side of the bridge superstructure. All 16 subsonic sea-skimming Urans can be ripple-fired in 2-3 second intervals and have a maximum range of 130 km. At least six have been test fired from the Mysore during her trials. These missiles are controlled by the Garpun Bal FC radar, mounted atop the bridge. This radar, unlike most fire control or search radars, combines active and passive channels. In the active target designation mode, it operates in X-band (I/J-band) and can handle up to 150 targets at  ranges  between 35-45 km although it is possible to obtain ranges of more than 180 km in wave-guide propagation conditions. The main gun armament comprises a single-barreled water-cooled 100mm automatic gun, the AK-100 which can engage aerial and surface targets at a rate of fire of 30-50 rds/min. The turret can traverse through an arc of 220ยบ. Fire control for the gun is provided by the T91E radar, a part of the MR-145 or MR-184 (NATO: Kite Screech) fire control radar system along with a turret mounted Kondensor optical sight. As in the later Kashins, four multi-barreled AK-630 Gatling guns, two on either beam, provide a last ditch inner layer of defence against incoming missiles that managed to leak through the outer layer of SAM defences.
