The Talwar-class frigates or Project 11356 are a class of guided missile frigates designed and built by Russia for the Indian Navy. The Talwar-class guided missile frigates are the improved versions of the Krivak III-class (Project 1135) frigates used by the Russian Coast Guard. The design has been further developed as the Admiral Grigorovich-class frigate for the Russian Navy. Six ships were built in two batches between 1999 and 2013.

Designed by Severnoye Design Bureau, the first batch of ships were built by Baltic Shipyard and the second batch by Yantar Shipyard. All the ships of the class have been named after weapons from Hindu mythology.

Preceded by the Brahmaputra-class frigates, the Talwar-class frigates are said to have semi-stealth features and better armament. The Indian Navy currently has six of these ships and plans to induct four more in the future.

On 17 November 1997, Russia and India signed a $1 billion contract, for three Krivak III-class multi-purpose frigates. The Indian Navy wanted to fill the gap created by the decommissioning of the Leander-class frigates until the Project 17-class frigates entered service.

After the signing of the contract, Severnoye Design Bureau began a detail design layout and the shipbuilder, Baltisky Zavod of St. Petersburg, began preparations for their construction. The project involved around 130 suppliers from Russia, India, Britain, Germany, Denmark, Belarus, Ukraine and other countries including over 30 St. Petersburg-based naval design organizations and institutes.
