Project 17 Shivalik

Project 17 Shivalik Class Frigate - Design

The P17 is an enlarged and modified version of the Talwar {Krivak III} Class frigates. It was jointly designed by the Naval Design Bureau (NDB) and Russia's Severnoye Project Design Bureau (Severnoye Proyektno-Konstruktorskoye Bjuro - SPKB). SPKB's design influence can be observed in the Delhi Class destroyers and Khukri / Kora Class corvettes. France's DCN International (DCNI) has been involved in this project as a consultant undertaking signature management studies.

Shivalik Class frigates can carry a crew of 257, including 37 officers. The total length of the ship is 142.5 meters while its breadth is 16.90 meters. The standard [light] displacement of the ship is 4,900 tons, while the full displacement of 6,000 tons. It is powered by gas and diesel turbines. These warships are capable of speeds in excess of 30 knots. The ships are fitted with a mix of Indian, Russian and Western weaponry systems alongwith both air defence and anti-submarine warfare capabilities. They also carry two advanced helicopters.

Shivalik Class frigates are the first Indian warships to be built with stealth features and which are designated to be the lead frigates of the country's navy during the first quarter of the 21st century. They are an upgraded and superior version of the Talwar Class frigates. These frigates include unique stealth features and land-attacking capabilities. The structural, thermal, and acoustic stealth features make them less detectable to the enemy. The radar systems and engines are further modified to reduce and avoid detection and noise levels.

Shivalik Class frigates are the first Indian warships to be built with stealth features and which are designated to be the lead frigates of the country's navy during the first quarter of the 21st century. The stealth frigate is designed to avoid enemy radars and and works on principles of reducing the ship's signature. They are an upgraded and superior version of the Talwar Class frigates. These frigates include unique stealth features and land-attacking capabilities. The structural, thermal, and acoustic stealth features make them less detectable to the enemy. The radar systems and engines are further modified to reduce and avoid detection and noise levels. The Shivalik Class ships have many more signature reducing features than other Indian Navy ships. They do not, however, possess extreme stealthy or low observable features like the Swedish Visby or the French Lafayette. The Shivalik Class ships will have a lower infra-red signature due to Infra-Red Supression System (IRSS) design tools and training provided by Canada's Davis Engineering.

The Canadian IRSS is the most effective IR signature reduction device in service today. An Italian Radar Cross Section (RCS) prediction software may also have been used for this design. All machinery will be mounted on noise and vibration-proof mounts to reduce acoustic and vibration signatures. Few countries which make stealth frigates indigenously. India would thus be joining an exclusive club, which includes the US, France and Russia.

The ships are armed with a formidable array of surface, sub-surface and air-defence weapons. These include long range anti-ship missiles, anti-aircraft missiles and anti-missile defence systems, which can detect and engage the enemy at extended ranges, thereby giving her significant combat power. The two multi-role helicopters that are embarked on Sahyadri provide enhanced surveillance and attack capability. The ship is mounted with Fregat M2EM 3-D radar, an air search radar, HUMSA (Hull-Mounted Sonar Array) fire control radar and BEL Ellora electronics surveillance measures.

The Computer-aided Action Information Organisation (CAIO), provides the Combat Centre with a complete electronic picture of the battlefield, including target information from the Sahyadri’s sensors and radars. This goes to the ship’s Executive Officer (XO), the weapons chief, who electronically assigns a weapon to destroy each target.

The ships are propelled by two Gas Turbine engines, which enable her to generate speeds in excess of 30 knots (or over 55 Kmph), and two Diesel Engines for normal cruising speeds. The ship’s electric power is provided by four Diesel Alternators, which together produce 4 Mega-Watts of power - enough to light up a small town.
