INS Shivalik (F47) is the lead ship of her class of stealth multi-role frigates built for the Indian Navy. She is the first stealth warship built by India.[5] She was built at the Mazagon Dock Limited (MDL) located in Mumbai. Construction of the vessel began in 2001 and was completed by 2009. She underwent sea trials from thereon before being commissioned on 29 April 2010.[6][7]
Shivalik features improved stealth and land attacking features over the preceding Talwar-classfrigates. She is also the first Indian navy ship to use the CODOG (COmbined Diesel Or Gas) propulsion system.[8]
Design and description
The Shivalik-class frigates were conceived as part of the Indian Navy's Project 17, which set down the requirements for a class of stealthy frigates to be designed and built in India.[9][10] The Directorate of Naval Design (DND)'s design specifications for the Shivalik class called for "5000 ton stealth frigates (Project 17) incorporating advanced signature suppression and signature management features".[11] The first three units were formally ordered by the Indian Navy in early 1999.[12]
General characteristics and propulsion
INS Shivalik has a length of 142.5 m (468 ft) overall, a beam of 16.9 m (55 ft) and a draft of 4.5 m (15 ft). The ships displaces about 5,300 t (5,200 long tons; 5,800 short tons) at standard load and 6,200 tonnes (6,100 long tons; 6,800 short tons) at full load. The complement is about 257, including 37 officers.[1]
The ship uses two 7,600 shp (5,700 kW) Pielstick 16 PA6 STC diesel engines, for cruising, or two 16,800 shp (12,500 kW) GELM2500+ gas turbines, for high speed bursts, in CODOG configuration. The diesels allow the ship to reach a maximum speed of 22 kn (41 km/h; 25 mph) while the gas turbines allow of a maximum speed of 32 kn (59 km/h; 37 mph).[8]
Electronics and sensors
INS Shivalik is equipped with a wide range of electronics and sensors. These include:
The construction of INS Shivalik began in 2000. Her keel was laid in July 2001. She was launched in June 2004 and was originally planned for commission by 2005[4] However, she was commissioned in April 2010.
After the deployment in the north Pacific, the battle group was deployed in the South China Sea.[17][18] As part of India's Look East policy, the ships visited the Shanghai port on 13 June 2012, for a five-day goodwill tour.[15][19] INS Shakti served as the fuel and logistics tanker to the three destroyers. The ships left the port on 17 June 2012.[20] Before leaving the port, the ships conducted a routine passage exercise with the People's Liberation Army Navy.[21][22][23]
After the visits to Singapore, Vietnam, Philippines, Japan, South Korea and China, the ships visited Port Klang, Malaysia. This was the battle group's last port call during its two-month-long deployment, which had started in May 2012. After this she returned to the Eastern Fleet of the Indian Navy and since has been docked there.[14][24][25]
INS Shivalik participated in the People's Liberation Army Navy's (PLAN) 65th anniversary celebrations held in Qingdao. India, Indonesia and China conducted three high level exercises including anti-hijack exercise. PLAN official who visited the ship mentioned that "The Indian ship is a very strong ship with powerful weapons," and "This gives us a good opportunity to see the Indian Navy". INS Shivalik sailed 4,500 nmi (8,300 km; 5,200 mi) from Port Blair to Qingdao, without being assisted by any support vessel and without official from headquarters, showcasing the confidence of the crew and the autonomy they enjoy. PLAN and Indian Navy decided to further deepen the Naval bond between the two nations.[26]
