The Dmitry Rogachev, number 375, is among six Project 22160 patrol ships under construction for the Russian Navy.
Rogachev was commissioned on 11 June 2019, and is currently serving in the Black Sea fleet.
Ships of this class are built to operate near, close-to-shore, to intercept potential threats at-speed and over range. The ship has a displacement of about 1700 tons, a length of 94 m, a beam of 14 m, and a draft of 3.4 m. This gives the vessel a certain “compactness” when operating in tight environments such as “closed” seas.
The propulsion scheme is a fuel-focused COmbined Diesel-And-Gas arrangement which sees twin marine diesels paired with gas turbines, the former offering 6,000 horsepower output for cruising actions while the latter is used to achieve faster “dash” speeds over distance. 4 Diesel generators are also installed. Dmitry Rogachev can reach a top speed of up to 30 knots, a range of 6,000 miles.
The overall design of the ship is all-modern with slab sides used to minimize its signature – this creates relatively smooth surfaces and elegant lines from bow-to-stern. The turreted deck gun is seated over the forecastle in the usual way, given excellent engagement angles ahead and to the forward-sides of the ship. The hull superstructure sports a sharply angled face and its bridge area is identified by a clean row of rectangular windows. Atop the bridge section is featured a low-profile, largely-enclosed main mast containing various communications, sensors, and radar fits.
The class’s armament includes the Kalibr-NK cruise missile, aerosol camouflage, two grenade launchers and two machine guns and a 76.2 mm dual-purpose gun. The ship also has a helicopter deck and hangar for one Ka-27 or Ka-226 helicopter. The ship also carries a landing speedboat, and has provisions for drones, underwater unmanned craft and unmanned boats. There is accommodation for an additional 60 men.
In 2020 it was announced that the Russian Navy would begin trials to test the installation of module containers on patrol vessels permitting such ships to carry significantly upgraded armaments tailored to different missions. The containers were envisaged to carry various weapons including sonars and torpedoes or anti-ship and cruise missiles.
Three of the six ships of this class have already entered service with the Black Sea fleet between 2018 and 2020. The remaining three will be delivered soon in 2022 and 2023, giving the Black Sea Fleet considerable capabilities in the region – particularly against neighboring Ukraine.
