Some additional info about the resume of progress on the Grigorovich frigates
Russia to resume the construction of the "last three" Project 11356 frigates in 2018
The United Shipbuilding Corporation (USC) will resume the construction of the last three Project 11356 frigates in 2018. Earlier, the construction of these ships was suspended due to Kiev's refusal to supply gas turbine power plants. The decision to resume the work was made following the preliminary testing of the latest Russian gas turbine units M70FRU and M90FR. According to experts, the advent of these ships will significantly expand the Navy’s capabilities in the Mediterranean Sea, the Central and North Atlantic, and the Arctic zone, the newspaper Izvestia writes.

At present, two of the six ordered ships of this class are operational with the Navy. The frigates Admiral Grigorovich and Admiral Essen are part of the Black Sea Fleet. Admiral Makarov is undergoing the official tests. The remaining three frigates of the "Admiral" series - Butakov, Istomin, and Kornilov - are currently mothballed in varying degrees of completion at the Kaliningrad-based Yantar Shipyard. They were intended for the Baltic Fleet. Their construction was frozen because of Ukraine's refusal to supply the DS71 and D090 power plants manufactured by Zorya-Mashproekt, Nikolaev, Ukraine and previously paid by Russia. It was assumed that the "Admirals" would be sold to the Indian Navy because of the inability to complete them. Aleksey Rakhmanov, the head of the United Shipbuilding Corporation, told Izvestia that the construction of the ships will be resumed in 2018, after the appropriate tests and follow-on development to accommodate the new power plants. "The decision has been made and R&D work will be required,"
explained Rakhmanov. However, due to the fact that design proceeded with regard to the groundwork laid by Russian gas turbine builders, no major modifications to the architecture of the ships will be needed. "We do not think that these R&D works will be so significant as to throw us back a few years ago."

As noted by Rakhmanov, the timing depends not only on gas turbine units - the shipbuilders will have to resume contracts on all major systems. "Therefore, it is very important here that we are able to comply with the warranty periods, the service life of equipment and the corresponding storage life,"
the head of USC said.
As Izvestia was told at the Navy's Main HQ, the tandem power plant configuration of two M70FRU gas turbine engines is being considered as the core project. According to preliminary calculations, this should ensure the maximum power output of 14,000 hp. In this case, the ship will be able to move at a speed of 30 knots and the cruising range will be 4850 nautical miles (9,000 km). This is quite enough to go from the Baltic Fleet’s main base at Baltiysk to Russia’s Tartus naval base in Syria without fuel replenishment.

Expert Alexander Mozgovoy told Izvestia that the decision to complete the Project 11356 frigates was welcome. "Our Navy really needs them and we would have lost three good ships in case of selling them to India,"
said the expert. "These are general-purpose ships that can operate in the Mediterranean, in the central Atlantic and in the north. We are in desperate need of such ships today as all the large Soviet-era ships are badly worn and their service life is nearing the end. In fact, there is no alternative to the Project 11356 frigates."
Project 11356 frigates are designed to attack enemy surface ships and submarines both in the near and far maritime zones, counter air targets, both independently and as part of a task force. Frigates of this type are armed with a 100mm A-190 gun, strike and air defense missile systems, including Kalibr and Shtil, torpedoes. The ship can carry a Kamov Ka-27 helicopter and its versions. The ship's displacement is 3620 tons and its length is 124.8 meters. The full speed is 30 knots and the cruising range is 4850 miles.Comment
The main problem with this plan is the development and manufacture of reducers for new gas turbine units, which can delay the completion of ships, more than the manufacture of the M70FRU gas turbine engines at NPO Saturn.
According to available information, the completion for the Russian Navy of three frigates of the modified project 11356 with the Russian all-mode main power plant based on gas turbine engines M70FRU is included in the draft State Armament Program for 2018-2025.
