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.Ukrainian engines of the Indian ships ARE confirmed. This was a precondition before the deal was signed. Besides, the Russian engines will take years before they are ready.
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)
