   The Shivalik class warships are one of the newest surface combatants of the Indian Navy. Also these are the first Indian-built warships with enhances stealth features. Many extraneous shapes and protrusions were eliminated from the design in order to minimize the radar cross section. Though these frigates are still not yet true stealth vessels.

   Due to their size and displacement the Shivalik class ships could be even considered as destroyers. However their armament is too light for a true destroyer. Still though these warships are very capable and are currently among the most deadly frigates of the world.

   A total of three ships were built between 2000 and 2010 and currently all of these warships are active. All of the Shivalik class ships were built by Mazagon Dock Limited shipyard. The Shivalik class frigates are successors of the Talwar class frigates.

   First vessel of the class, the INS Shivalik, was commissioned on 29th April 2010. Second vessel of the class, the INS Satpura, followed on 20 th August 2011. The last vessel, the INS Sahyadri, was adopted by the Indian Navy on 21st July 2012.

   Each Shivalik class frigate is operated by a crew of 257 sailors, including 37 officers.

   These Indian frigates have a strong anti ship and land attack capability. These are armed with a universal 8-cell Vertical Launch System (VLS) for BRAHMOS supersonic cruise missiles and Klub-N anti-ship cruise missile. The BRAHMOS missiles have a top speed of Mach 3 (3 700 km/h) and can engage sea or land targets at a range of 290 km. It seems that BRAHMOS cruise missile have been fitted on most Indian frontier warships. The Klub-N anti-ship cruise missile (SS-N-27 Sizzler) is an export version of the Russian Kalibr-NK. It has a range of 440-660 km.

   There is a single-arm reloadable launcher for Shtil-1 (SS-N-12) air defense missiles. These missiles have a 40 km range. A magazine holds 24 of these air defense missiles and it takes 6 seconds for the missile to reload. This particular system is badly outdated. All modern warships are fitted with vertical launch systems for their primary surface-to-air missiles. Also the Shtil-1 launcher has a limited firing arc and can engage targets only to the front of the ship. The Shivalik class frigates are also fitted with two 8-cell VLS launchers for Barak-1 air defense missiles. It is a much more modern weapon, used for short-range defense against sea-skimming anti-ship missiles, as well as other threats. A total of 32 of these missiles are carried.

   Radars of the Shivalik class can detect air targets at a range of over 350 km. However the fire control radar is of older generation. So these frigates can engage simultaneously only 6 air targets.

   There are two 533-mm tubes for heavyweight torpedoes for engaging submarines and surface warships. There are also two RBU-6000 anti-submarine rocket launchers, with 12 barrels each. Reload rockets are stored below the deck.

   Also there is an OTO Melara 76-mm Super Rapid Gun, which is highly effective both against air and surface targets. It has a range of 17 km and fires at a rate of 120 rounds per second. Last ditch defense against incoming missiles is provided by two AK-630 Close-In Weapon Systems (CIWS). For submarine detections these frigates are fitted with Indian hull mounted sonar and towed sonar system.

   These frigates can carry two helicopters. These may be either indigenous Dhruv light utility helicopter, British Westland Sea King anti-submarine or multi-purpose helicopter, or Russian Ka-31 airborne early warning helicopter.

   The Shivalik class frigates are driven by a Combined Diesel or Gas (CODOG) propulsion system. Vessels are fitted with two Pielstick 16 PA6 STC diesel engines deliver 15 142 shp each and two General Electric LM2500 gas turbines, delivering 33 600 shp each. Diesel engines are used for low speed cruising, while the gas turbines are turned on when maximum speed is required. Maximum speed is 22 knots (41 km/h) on diesel engines and just over 30 knots (56 km/h) when operating with gas turbines. Maximum range is 5 000 nautical miles (9 260 km) at 15 knots (28 km/h).
