Project 21820 Landing Craft, Russia
The Baltic Fleet of the Russian Navy commissioned a series of three Project 21820-class landing craft by July 2015. All three ships were designed by JSC Alexeev's Central Hydrofoil Design Bureau and built by OJSC Yaroslavsky Shipyard.
A total of five Project 21820 class landing craft are in service with the Russian Navy. The ships are intended for delivery of troops, and wheeled and tracked vehicles from the sea to the unequipped coasts during an amphibious assault.
Project 21820 landing craft orders and deliveries
Yaroslavsky Shipyard signed a state contract with the Ministry of Defence of Russia for the construction and delivery of a series of three Project 21820 landing craft in June 2011 to perform the tasks of the Russian Navy's Baltic Fleet.
Keel for the first vessel in the series, Denis Davydov (building no. 701), was laid in January 2012 and the launch was held in July 2013. Sea trials were performed during June and October 2014. Denis Davydov was commissioned into the Baltic Fleet a month later.
The second landing craft in the series, Lieutenant Rimsky-Korsakov (702), was launched in April 2014 and completed mooring tests in October. It underwent factory sea tests between October and December that same year.
Keel for the third in the series, Michman Lermontov (703), was laid in January 2013 and its launch took place in June 2014. The Michman Lermontov's factory sea trials were conducted in December 2014.
Another two Project 21820 class landing craft ordered by the Russian Ministry of Defence are Ataman Platov and Ivan Kartsov.
The Ataman Platov medium landing craft was commissioned into the Caspian Flotilla in 2010, while the Ivan Kartsov amphibious ship was deployed in the Pacific Fleet in 2013.
Design and features of Project 21820 landing craft
The Project 21820 class landing craft features an air cavity hull. It has a maximum length of 45m, a width of 8.5m, and a draft of 1.9m. It is equipped with a 27m-long, 6.8m-wide and 2.34m-high cargo compartment to accommodate a variety of loads.
With a total displacement of 280t, the vessel can carry up to 140t of loads such as three T-72 main battle tanks or one T-72 main battle tank (or BTR-80 / BTR-82A) armoured personnel carrier and 90 troops, or five BTR-80 / BTR-82A troop carriers and 50 troops. A ramp on the bow allows loading / unloading of supplies and equipment.
The ship is operated by a crew of seven from the navigation bridge, placed at the rear portion. The square windows on front and sides of the bridge provide a clear view of the horizon.
Project 21820 landing craft weapons
The landing craft is armed with two Vladimirov KPV 14.5mm marine pedestal machine guns (14.5mm MTPU-1) to defeat lightly armoured targets on land, air and sea.
The machine gun has a rate of fire of 450 rounds a minute. It can reach up to a distance of 3km against surface targets and up to 2km against air targets.
A cannon mounted on each side of the bridge offers protection from small arms fire.
Sensors onboard Project 21820 landing craft
Equipments aboard the Project 21820 landing craft include marine radar mast, navigation systems, radio equipment, antennas, lighting systems, and communications systems.
Propulsion and performance of Project 21820
The Project 21820-class is powered by two ?507?-2D diesel engines, rated at 9,000hp each. The water jet propellers with ventilation deliver high efficiency and high-speed capabilities.
The ship can reach a maximum speed of 35kts at the wave heights of 0.75m, and its maximum floating distance is 500nm.
