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. 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.

Shivalik features improved stealth and land attacking features over the preceding Talwar-class frigates. She is also the first Indian navy ship to use the CODOG (COmbined Diesel Or Gas) propulsion system.

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. 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". The first three units were formally ordered by the Indian Navy in early 1999.

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.

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) GE LM2500+ 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).
