Last month, Strategy Page looked at the Mistral class ships, both the original French Navy ships and the two that have been built for — but not delivered to — the Russian navy:
Russia has not bought foreign warships for a long time, but the Mistral purchase was largely because of an eagerness to acquire Western shipbuilding technology and construction skills. This has already paid off, although not exactly how the Russians had planned. This became evident when a Russian official announced that the first Mistral would be built entirely in France. It had earlier been decided to have Russian shipyards build some sections of the first Mistral. It was quickly discovered that the Russian shipyard was not capable of building to the French specifications or do it according to the French timetable. The Russians expected to learn some valuable lessons from the French and, while embarrassing, this was one very valuable lesson. Russian shipyard officials have had their faces rubbed in the embarrassment of not being able to compete while using their current practices. Russian experts on Western production methods and techniques have long complained of the antiquated and inefficient methods still favored by Russian shipbuilders. Navy leaders have been complaining for decades about the poor quality of work coming out of Russian shipyards. The Mistral purchase was to put this to the test because additional Mistrals were to be built in Russia, with plenty of French supervision and technical assistance. That is also being withheld because of the Ukraine situation.
The Russian Navy has made some changes in the existing Mistral design. This Russian model will be called the Vladivostok Class and carry 30 helicopters (compared to 16 on the French version). The Vladivostoks will be armed with two AK-630 multibarrel 30mm autocannon for anti-missile defense. There will also be two quad-launchers of shoulder fired type anti-aircraft missiles (with a 5 kilometer range and does well against helicopters) and two or more DP-65 55mm grenade launchers for defense against divers.
The Vladivostoks will also be winterized for use in arctic conditions. The hull will be strengthened to deal with ice and the well deck door will completely close. The flight deck will have a deicing system and the ship will be modified to operate for extended periods in arctic conditions. There is also different electronics and this means a different arrangement of radomes and antennae.
In the aircraft handling areas below the deck, there will be more space made for the taller Ka-52K and Ka-29 helicopters. The Ka-52K is a navalized version of the Ka-52. In addition to being equipped with coatings to resist sea water corrosion, the K model will also have a lightweight version of the high-definition Zhuk-AE AESA radar used on jet fighters. This radar currently weighs 275 kg (605 pounds), but the helicopter version will weigh only 80 kg (176 pounds) and enables the Kh-52K to use the Kh-31 anti-ship missile. This weapon has a range of 110 kilometers and travels at high speed (about one kilometer a second). The Kh-52K can also carry the sub-sonic Kh-31 missile, which has a range of 130 kilometers. Both of these missiles weigh about 600 kg (1,300 pounds) each.
The French navy received the first of their own 21,500 ton Mistrals in 2006, with the second one arriving in 2007. Both were ordered in 2001. These two ships replaced two older amphibious landing ships. This gave France a force of four amphibious ships. The two Mistrals are also equipped to serve as command vessels for amphibious operations. The French have been very happy with how the Mistrals have performed.
I believe the French navy actually has three ships of this class in service: Mistral, Tonnerre, and Dixmude.
