The Shivalik class or Project 17 class is a class of multi-role frigates in service with the Indian Navy. They are the first warships designed with low observability features built in India. They were designed to have better stealth features and land-attack capabilities than the preceding Talwar-class frigates. A total of three ships were built between 2000 and 2010, and all three were in commission by 2012.

Stealth technology, also termed low observable technology, is a sub-discipline of military tactics and passive and active electronic countermeasures, which covers a range of methods used to make personnel, aircraft, ships, submarines, missiles, satellites, and ground vehicles less visible to radar, infrared, sonar and other detection methods. It corresponds to military camouflage for these parts of the electromagnetic spectrum.
