The Gremyashchy, a sophisticated new Russian naval ship, will be equipped with domestically made engines, according to the press service of the Russian Defense Ministry.
The Project 20385 Gremyashchy corvette will get the engines before the end of May 2015, according to the Ministry.
The Russian Navy had previously planned to equip the corvette with engines produced by the German company MTU. However, like dozens of other contracts with companies from countries which imposed sanctions against Russia in 2014, these plans were scrapped.
With the four engines due to be transported to the Gremyashchy by the end of May, the warship’s state trials will begin in 2017, according to the Russian newspaper Rossiyskaya Gazeta.

This multi-role ship is being built at St. Petersburg’s Severnaya Verf Shipyard; it is designed for antisubmarine and surface warfare as well as for supporting land operations. The vessel is made of composite materials and incorporates stealth technology, which has considerably reduced its radar and infrared signatures.

The Gremyashchy has a crew of 99 and is equipped with artillery, missile and anti-submarine weaponry, as well as an advanced radar sytem.
Its armaments include Kalibr-NK universal missiles, a Redut anti-aircraft missile system and a A-190-01 100mm gun. It also has a hangar for operating a Kamov Ka-27 antisubmarine warfare helicopter.
The 104-meter-long corvette has a full displacement of 2,200 metric tons and a maximum speed of 27 knots (about 50 kilometers) per hour.

Конструкция – корпус стальной гладкопалубный. Обводы подводной части корпуса позволяют снизить сопротивление воды при движении корабля на скорости около 30 узлов примерно на 25 % а также позволяют уменьшить потребную мощность энергетической установки. По сравнению с кораблями пр.20380 изменена конструкция надстройки. Надстройка корабля выполнена с использованием многослойных композиционных материалов – трудногорючих многослойных стеклопластиков и конструкционных материалов на основе углеродистого волокна. Конструкция надстройки разрабатывалась с учетом современных требований к радиолокационной заметности. В кормовой части корабля размещен ангар для вертолета.
The Gremyashchy-class corvettes differ from their predecessors of the Steregushchy class by greater dimensions and displacement. They have a steel hull and composite superstructure, with a bulbous bow and nine watertight subdivisions. Compared with theSoobrazitelny, Boiky, Sovershenny and Stoiky ships, which are fitted with Redut air defense VLS system of 12 launchers on the bow, these new ships are equipped with a UKSK VLS system comprising 8 launchers for SS-N-27 or SS-N-26 cruise missiles instead. The Redut VLS system with 16 launchers has been replaced on the stern. Another difference is the lack of the aft mast above the helicopter hangar, and single integrated mainmast that no longer includes separate open shelves for artillery and navigation radars.
