Ivan Gren (class) / History of Project 11711

The Project 11711 amphibious transport ship was developed for the Russian Navy as a successor to the previous Project 1171 Tapir (Western name Crocodile-class) landing ship. It Often referred to as the Ivan Gren class, after the lead ship.

According to the Russian classification, these ships are called large landing ships.

The battleship Ivan Gren of this class was launched in 2004, but was not launched until 2012 due to funding problems. In 2017, the ship completed construction tests. It entered service with the Russian Navy in 2018. It is currently in service with the Northern Fleet.

Another ship of the same class was ordered in 2010. It was formulated in 2015 as Petr Morgunov. Commissioning is planned around 2019-2020. The second ship of this class is also deployed in the Northern Fleet.

Two more such amphibious transports are being built for the Pacific Fleet, but these will be built to improved standards. The two additional DropShips were laid in 2019.

Initially, the Russian Navy planned to operate a total of six Ivan Gren-class DropShips, but the number was reduced to four due to funding issues.

In 2010, the Russian Navy ordered two Mistral-class amphibious assault ships from France. These are more powerful ships than the Ivan Gren class. However, the deal was eventually cancelled by France due to Russia's military operations in Ukraine.

In 2015, two French-built ships under a Russian contract were sold to Egypt.

The primary mission of the Ivan Gren-class ships is amphibious landing operations. It can perform traditional beach attacks. The ships can also be used for the logistical transport of military vehicles and cargo.

The Ivan Gren class is actually based on the proven Project 1171 Tapir DropShip mass-built by the same shipyard. However, the Ivan Glenn has been significantly revised and has little in common with its predecessor.

Several steps have been taken to reduce the radar cross section of the ship, making it more stealthy from radar. However, these amphibious DropShips are by no means true stealth ships.

The Ivan Gren class can transport up to 13 main battle tanks with a maximum weight of 60 tons. Alternatively, it can carry up to 36 infantry fighting vehicles or armoured personnel carriers, or 300 marines.

In order to launch an attack on the beach, the ship uses internal ramp bow doors to disembark vehicles. There is also a stern ramp for fast landing craft. The ship carries a total of 2 or 3 landing craft.

Ivan Gren has a heliport on deck and hangar for two Ka-29 attack transport helicopters. These helicopters can land Marines on land and support amphibious operations with their firepower. Ka-29 helicopters can also be used for supply transport and medical evacuation missions.

Initially, the Ivan Gren class ships were planned to be armed with a dual-purpose 100mm gun, two Grad-M 122mm MLRS for saturated coastal bombing, and two Palasch anti-aircraft gun/missile systems. However, In 2010, the Russian Navy decided to simplify the armament of the landing ship in order to reduce production costs.

Ultimately, the lead ship was equipped with less capable weapons, including an AK-630M-2 Duet melee weapon system with two 6-barrel 30mm automatic cannons and two additional 6-barrel AK-630M 30mm melee weapon systems. All of these weapons can be used against land, surface and air targets, as well as close-range defense against incoming anti-ship missiles.

There are also two heavy 14.5mm machine guns.

The Ivan Gren class is equipped with a decoy-launching countermeasure system. The system reduces the chance of being hit by enemy missiles.

This military transport vessel is powered by two 5,000 hp diesel engines. Power is transmitted on two axles. The maximum range is 6,480 km (3,500 nautical miles) and the speed is 30 km/h (16 knots). The voyage without replenishment is 30 days.
