Armée Russe / Armed Forces of the Russian Federation

Air wing:
Following a requirement from the Russian Navy, the air wing of the Russian landing ships is increased compared to the French Navy Mistrals. The Vladivostok is designed to accommodate 30 Ka-52K Alligator and Ka-29 helicopters instead of the originally planned 16 helicopters. This will increase the landing and overall power projection capacities of the ships.

Ka-52K Alligator (NATO reporting name: Hokum B)
The Ka-52K is a navalized version of the land-based Ka-52 Alligator combat helicopter operated by the Russian Air Force. The special "navalized" version of the helicopter will be specially equipped to conduct attack missions against targets at sea and on the ground which requires different sensors and armaments than those used on the basic Ka-52 helicopter.The major difference will be the radar: A modified version of the Mig-35 fighter's Zhuk-A phased array radar is currently being developed to fit into the Ka-52K nose cone. This will be a major step forward compared to the base Ka-52 helicopter as the AESA radar Zhuk-A is among the most advanced radars to date in Russia. The radar is stated to provide a detection range of 130 km for a head on target with up to 30 targets tracked and 6 of those engaged at any one time.
Ka-52K will also feature folding rotor blades, folding wings and anti-corrosion treatment to fuselage and systems which are a necessity for any helicopter set to operate from a ship.
Another significant improvement for the Ka-52K over the Ka-52 is the reported possibility to launch Kh-31 (AS-17 'Krypton') and Kh-35 (AS-20 'Kayak') anti-ship missiles.

Ka-29 (NATO reporting name: Helix B)
Ka-29 Helix, based on the Ka-27 ship-borne helicopter, was originally designed for the Soviet navy as a dedicated assault and transport helicopter. In transport configuration the Ka-29 can carry 16 equipped soldiers or 10 wounded including four stretchers (medical supplies and equipment included). 2000kg cargo may be carried internally or 4000kg externally. A winch may also be installed. Ka-29 helicopters can also provide fire support for the landing party. In a combat configuration the helicopter is fitted with a 9A622 Gatling type 7.62-mm machine gun, eight 9K114 Shturm (AT-6 Spiral) or 9M120 Ataka-V (AT-9 Spiral-2) anti-tank missiles, up to four 57-mm or 80-mm rockets pods and two GS-23L twin-barrel 23-mm gun pod.

As for Ka-52K, the Ka-29 rotors and wings may be folded for storage inside the Mistral class vessel's hangar.

Landing crafts:
If the Russian Navy selects Russian made landing craft for their Mistrals, they will likely be project 11770 Serna or project 21280 Dyugon, those being the latest landing craft projects in Russia.
Project 11770 Serna has a displacement of 99.7 tons and maximum speed of 30 knots. It can transport one main battle tank or two armored personnel carriers or 92 soldiers.
The larger Dyugon (Project 21280) has a displacement of 280 tons and maximum speed of 35 knots. Dyugon can carry three main battle tanks or five armored personnel carriers. Dyugon may have to be slightly modified as its mast appears to be too tall to be able to fit inside a Mistral class vessel’s well-deck.

However, according to some reports, Russian Navy may be procuring French made L-CAT landing catamaran instead. Designed to land troops and military vehicles from an over-the-horizon amphibious vessel (30 nautical miles/55 km), the L-CAT has a payload of 80 tons with a maximum speed of 30 knots. Its doors at the front and rear simplify the loading and unloading of vehicles.

Weapons:
Vladivostok type Mistrals are set to receive a fully Russian weapons fit.
Self protection against air threats will be fulfilled by two Gibka 3M-47 air defense missile system: One located the bow, port side and another system located at the stern, starboard side.
Two AK-630M CIWS are set to be fitted (bow, starboard side and stern, port side) for close range protection against air and surface threats.
Some 14,5mm heavy machine guns are planned to be installed on Vladivostok for protection against close range asymmetrical threats.
Four DP-65 antisaboteur grenade launchers will be fitted on each side of the vessels. It is designed for protection of ships against attacks of underwater combat swimmers at external roadstead open anchor stops and bases. The system ensures single-shot and salvo fire with rocket grenades RG-55M and RGS-55.

Other notable modifications include increased hangar height to accomodate the Kamov helicopters, modified bridge structure, reinforced hull to operate in Arctic zones, specific warming devices on deck, a door that completly closes the well-deck (on French Mistrals, the well-deck door doesn't reach the top of the well-deck, leaving an opening) and several russian specific systems (note the several radomes placed at different locations in the image above).

With a length of 199 metres, a displacement of 22,000 tonnes and a speed in excess of 18 knots, the Mistral class LHD offers a global projection capability for troops and materiel, including heavy helicopters and landing craft, as well as ample capacity as a hospital or evacuation vessel for large- scale humanitarian missions. The design also features electric propulsion using azimuth pods and high-level automation compatible with a complement of just 170, while a high-performance communications suite makes the type ideal for the naval force command vessel role.

The first two ships of this type, Mistral and Tonnerre, were built by DCNS and STX France and delivered to the French Navy in 2006 and 2007 respectively. France's third LHD of the type, Dixmude, ordered by the French defence procurement agency in 2009, was delivered by DCNS and STX France on 3 January 2012, three months ahead of the contract schedule.
