| notes | "The Admiral Grigorovich class, also referred to as Krivak IV class, Russian designation Project 11356Р/М, is a class of frigates built by the Yantar Shipyard in Kaliningrad for the Russian Navy. Based on the Talwar class, six ships were ordered for the Russian Black Sea Fleet under two contracts in 2010 and 2011 as a complement to the Admiral Gorshkov class frigates.
By 2010-2011, it was decided the Russian Navy will procure six vessels based on the proven Talwar class design, mainly due to repeated delays with production of Admiral Gorshkov frigates and because of the urgent need for new frigates necessary for modernization of the Black Sea Fleet. The Yantar Shipyard won the contract for construction of the frigates and three vessels was to be completed in four years. Previously, six ships of the same design, known as Talwar class, were built for the Indian Navy between 1999 and 2011 by the Baltic Shipyard, Saint Petersburg and Yantar Shipyard, Kaliningrad.
The lead ship, Admiral Grigorovich, was laid down on 18 December 2010 and was commissioned on 11 March 2016.
Initially, Ukrainian state-owned enterprise Zorya-Mashproekt was providing gas turbines for the Russian frigates, but after the Ukrainian crisis, Ukraine said it would no longer supply the engines. Instead, Russian manufacturer Saturn was asked to supply alternative M90FR gas turbines.
Since October 2016, it was claimed the three incomplete frigates, Admiral Butakov, Admiral Istomin and Admiral Kornilov, that construction was suspended in 2015 due to Ukraine's refusal to supply gas turbine power plants, are considered to be sold to India. The Russian Navy has opposed this export.
On 1 June 2017, the United Shipbuilding Corporation (USC) announced that it would resume construction of the last three frigates in 2018 and that the ships will later join the Russian Navy. The decision to resume the work was made following the preliminary testing of latest Russian gas turbine engines, the M70FRU (14 MW), M70FRU2 (6-8 MW) and M90FR (20 MW , maximal 25-28 MW), from the United Engine Corporation, built at NPO Saturn and TurboRus plants. With an access to alternative power plants, the ships were believed to remain in Russian service.
However, on 27 October 2018, India's Ministry of Defence and Russia signed a US$950 million deal for delivery of two incomplete Admiral Grigorovich-class frigates to the Indian Navy. Reportedly, these are to be Admiral Butakov and Admiral Istomin frigates, previously being built for the Russian Navy.
As of February 2019, the last three vessels remain without engines.
On 3 November 2016, as part of Russian military intervention in the Syrian Civil War, Admiral Grigorivich was deployed to the Mediterranean Sea for the first time. On 15 November 2016, it has launched Kalibr cruise missile on IS and Al-Nusra targets in Syria's Idlib and Homs provinces, destroying ammunition warehouses, gathering and training centers and weapon production plants.
Admiral Grigorivich was redeployed to the Mediterranean Sea in April 2017, following the US missile strikes against Syria.
On 20 November 2018, Rosoboronexport and Goa Shipyard signed a US$500 million deal for construction of additional two Admiral Grigorovich-class frigates for the Indian Navy. The frigates are to be license-built at the Goa Shipyard in India under a technology transfer from Russia. The construction is expected to start in 2020, with first vessel to be delivered in 2026 and second in 2027." |
