Ivan Rogov Class (Type 1174) Landing Ship, Russia
The Project 1174 large landing ship was built by the Yantar Shipbuilding Plant at Kalingrad for the Russian Navy. Three ships were built, the Ivan Rogov, the Aleksandr Nikolaev and the Mitrofan Moskalenko. The Russian Navy decommissioned Ivan Rogov in 1996 and Aleksandr Nikolaev in 1997. The last ship in the class, Mitrofan Moskalenko is still in service with the Russian Navy.
The ship provides sealift and landing of troops and equipment. Military materiel is landed via a bow ramp and also via assault boats through the doors of the flooded well.
Project 1174 design
The tank deck covers an area 54m×12.3m to provide 660m² of floor area for the transportation of material and is accessed via the bow ramp. The docking bay, with doors at the stern of the ship, can be flooded for amphibious operations using small landing craft. The docking bay measures 67.5m by 12.3m.
The ship has the capacity for the military lift of one battalion of 520 marines and 25 tanks. If no landing craft are carried then the additional space in the docking bay allows a total of 53 tanks or 80 armoured personnel carriers to be transported.
The OSA-M (Nato codename Gecko) air defence missile system. supplied by the Znamya Truda Plant in Moscow, provides defence against anti-ship missiles, aircraft and surface targets.
The ship carries 20 missiles. Range is up to 10km and the reaction time is up to 20s. The system uses semi-active radar homing. The ship is equipped with two close-range, portable, Strela-3M air defence missile systems, each system having a quadruple launcher. The Nato code name for the Strela-3M is the Grail.
The ship has a 75mm AK-726 multipurpose twin gun, with 1,000 rounds of ammunition, supplied by the Frunze Arsenal Design Bureau in Saint Petersburg and by the Barrikady Production Association in Volgograd. The maximum firing range is 15.7km and the gun is capable of firing up to 100 rounds a minute. Laying of the gun mount and the fire control can be carried out in automatic mode using the fire control radar system, in semi-automatic mode using the Prizma optical sighting device mounted on the turret or in manual mode using the gunner's sights.
The ship is armed with four 30mm AK-630 air defence guns manufactured by the Ametist Design Bureau, Izumrud JSC and the Tula Engineering Plant JSC. The AK-630 is for engaging airborne threats, small sea targets, floating mines and light armoured coastal targets.
The ship has a 122mm Grad-M rocket launcher with 320 rockets.
The Project 1174 ship accommodates four helicopters. The helicopter hangar is located within the superstructure. There is one landing pad forward of the superstructure and one behind the superstructure. The ship's helicopters are the Kamov Ka-27 or Ka-29. The Ka-27 (Nato codename Helix) is a naval anti-submarine helicopter and the Ka-29 is the combat transport version. The helicopter has the capacity to ferry 16 troops or 2t in the cabin plus 4t on a sling.
The ship's radar systems include a surveillance radar operating in E-band, two I-band navigation radars, and three fire control radars: G-band for the 76mm gun, H/I band for the 30mm guns and F/H/I band for the Osa-M missile system.
The ship is fitted with a radio communications suite with 17 channels, optronic fire control system and electronic warfare system with electronic support measures and countermeasures.
The ship's propulsion is provided by two gas turbine engines, each rated at 18,000hp. There are two shafts driving two fixed-pitch propellers. The ship has two retractable thrusters for manoeuvring and position keeping. The range at the maximum speed of 19kt is 6,000 miles. At a speed of 14kt the range is increased to 7,500 miles.
