Krivak IV Project 1135.6 - Program

The main objectives of the Russian Shipbuilding Agency for 2004 in the military sector included the Sankt Petersburg class diesel sub for the Russian and foreign customers; project 11356 frigate; mine sweeper; combat and patrol cutters, specialized and auxiliary ships (fire control, divers', hydrographic, demagnetizing, floating berths).

The Project 1135.6 Dozorny Frigate [and a number of other vessels] were to be built to replace Project 956 destroyers used by the Navy. The Russian Navy issued a Request for Proposal (RFP) in early 2002 for the construction of 10-20 frigates in the 4,000-ton range. Budgetary restrictions and a general halt on new projects, delayed the decision. The RFP was re-issued on 28 February 2005. Bidding was supposed to conclude by 01 April 2005, with a decision anticipated by the end of 2005.

Two shipyards were considered frontrunners for the program: Baltic Zavod - which at the time had no major construction projects; and Severnaya Verf, which was building the Steregushchy-class frigate. Plans call for building at least 10 units of the class, at a unit cost of about $200 million, and possibly as many as 20 total. If the project moves ahead as planned, the first unit would launch by the end of 2006 and commission in mid-2007. This competition was reportedly won by Severnaya Verf, and nothing more was heard of Baltic Zavod's Project 1135.6 Dozorny.

The lead warship in the series, the Admiral Grigorovich, was laid down in December 2010, the second, the Admiral Essen, in July 2011 and the third, the Admiral Makarov, in February 2012. Russia's first Project 11356 frigate, the Admiral Grigorovich, was to join the Black Sea Fleet in 2014, Vice-Admiral Alexander Fedotenkov said on 29 April 2013. “The newest Project 11356 escort ship, the Admiral Grigorovich, should be launched in 2013 and join the Black Sea Fleet in 2014,” Fedotenkov said.

The Yantar shipyard in Russia’s Baltic exclave of Kaliningrad launched construction of a new Project 11356 frigate for the Russian navy on 13 July 2013. The official ceremony, attended by Deputy Commander of the Baltic Fleet, Rear Admiral Sergei Popov, was held Friday, according to Baltic Reporter online news portal. The Admiral Butakov was the fourth in a series of six Project 11356, or Admiral Grigorovich-class, frigates for delivery to the Black Sea Fleet between 2014 and 2016 under a contract with the Defense Ministry.

The Yantar shipyard in Russia’s Baltic exclave of Kaliningrad floated out the first in a series of six Project 11356 frigates being built for the Black Sea Fleet, the company said 14 March 2014. Four more ships of the same class were in various stages of construction at the shipyard. All six frigates will be delivered to the Black Sea Fleet between 2014 and 2017 under two contracts with the Defense Ministry.

Patrol ship "Admiral Grigorovich" - Project 11356 frigate head being built for the Russian Navy at the shipyard "Yantar", in late March 2015 began sea trials in the Baltic. Spokesman for the company Sergei Mikhailov said, "It is planned that the sea trials" Admiral Grigorovich "will begin on March 26-27. At present, the factory ship dock completes work on the demagnetization, and then move to the acceptance base in the ports of the Baltic". Sea trials patrol boat, which goes to the Black Sea Fleet, will last presumably before the end of May, after which it would be transferred to the customer.

The first in a series of six Admiral Grigorovich class (Project 11356) frigates, being built for the Black Sea Fleet, will be delivered to the Russian Navy in August, the United Shipbuilding Corporation said 08 April 2015. "The delivery of the Admiral Grigorovich frigate is planned for August 2015," the company said in a statement. "Admiral Grigorovich" was laid down in December 2010, was launched in March 2014.

Admiral Grigorovich successfully carried out the final stage of state trials in the Barents Sea, the shipyard's spokesman Sergei Mikhailov said 30 December 2015. The second and the final stage of state trials was over. The vessel was expected to return to Baltiysk in the first ten days of January…Raising the flag was expected to take place in February," Mikhailov told RIA Novosti.

Under two contracts signed with the Ministry of Defense, "Yantar" was building a series of patrol ships of project 11356 development of the Northern Design Bureau. In addition to the "Grigorovich" in this series of modern frigates for the Black Sea Fleet includes "Admiral Essen," "Admiral Makarov", "Admiral Butakov" and "Admiral Istomin." The Kaliningrad shipbuilders planned to complete the construction of the series in 2017.

The second Project 11356 frigate "Admiral Essen", was built for the Russian Navy at the Baltic Shipyard "Yantar" in Kaliningrad. "Frigate" Admiral Essen "made out in the Baltic Sea last Saturday and Sunday During the voyage the main attention was paid to test the main power plant of the ship, its work in various modes, and tested and some other important components and mechanisms", said enterprise press secretary Sergei Mikhailov on 08 Februrary 2016.

Frigate "Admiral Essen", which was initially based at the acceptance in the ports of the Baltic, began the state testing program on 30 January 2016. State tests, which are held on sea proving grounds of the Baltic Fleet, will last about a month. The transfer of the Russian Navy ship was scheduled for April 2016.

TFR "Admiral Essen" was laid at Shipyard "Yantar" on July 8, 2011, launched on November 7, 2014, the factory sea trials began October 28, 2015. For two contracts signed with the Ministry of Defense, the factory "Yantar" was building a series of six Project 11356 patrol ships, developed by JSC "Northern Design Bureau". The head of the frigate project modernized "Admiral Grigorovich" recently completed state tests, which were conducted in the Baltic Sea and the Northern Fleet. Its transmission to Navy was tentatively scheduled for the end of February 2016.

The Russian Ministry of Defense originally signed two contracts with Yantar Shipyard between 2010 and 2011 for the construction of six Project 11356 frigates. The Admiral Makarov was laid in February 2012; Admiral Butakov was laid in July 2013; and Admiral Istomin was laid down in November 2013. Later on, one of the projected vessels - Admiral Kornikov - was cancelled as Russia decided to replace it with a more powerful Admiral Gorshkov class frigate of Project 22350. The vessel was laid down on February 1, 2006 at a shipyard in St. Petersburg. It was also due by the end of 2015.

Terms of delivery to the Russian Navy of the newest frigates were under threat because of the backlog with the development of missile systems. This was reported 24 March 2017 by Deputy Defense Minister Yury Borisov. "Due to the untimely performance by the Almaz-Antey concern of the development works Polymet-Redut and Shtil, the terms of delivery of the 22350 Admiral Gorshkov and 11356 Admiral Makarov ships are in jeopardy, Borisov said. According to him, the main reasons for late delivery were the low level of organization of their work, delays in the supply of components, insufficient production capacity and a lack of qualified personnel. In total, six ships were planned for this project, of which in 2016 the fleet received two - Admiral Grigorovich and Admiral Essen. "Admiral Makarov" was on state tests. The fourth and fifth ships of the series will be transferred to India, the fate of the sixth was still unknown.

The final decision on the fate of the sixth frigate of Project 11356 built by the Baltic Shipyard (PSZ) Yantar (part of the United Shipbuilding Corporation) has not yet been made. This was announced 10 Janary 2022 to TASS by the general director of PSZ Ilya Samarin. "The sixth building of project 11356 is currently mothballed and is located in the water area of the plant, the final decision has not been made," he said, answering the question whether the RF Ministry of Defense has decided on the fate of the sixth building of this project.

The initial plans included the construction of six Project 11356 frigates for the Black Sea Fleet (BSF) of Russia. However, these plans had to be adjusted after Ukraine's refusal to supply power plants. As a result, the Black Sea Fleet received three frigates of this project, three hulls were launched.

In 2018, a contract was signed according to which PSZ will complete the construction of two hulls for the Indian Navy, and two more, with Russian participation, will be built at the Indian shipyard Goa Shipyard Ltd. The gas turbine units were directly purchased by India from Ukraine and will be supplied to Yantar by the Indian government. The first two ships built by PSZ were planned to be transferred to the Indian Navy in 2023 and 2024.

In the Russian version of Project 11356, each frigate carries two universal shipborne firing complexes for eight Kalibr-NK and / or Onyx missiles. Indian frigates will receive Russian-Indian anti-ship missiles "BrahMos". On the Russian side, the Reutov NPO Mashinostroeniya (part of the Tactical Missile Armament Corporation) takes part in the joint venture of the same name.

Earlier PSZ and Baltiysky Zavod built six Project 11356 frigates for the Indian Navy.
