    If they did I would say it was because there was no alternative at the time and the time it would take to develop a Russian alternative would have delayed the project?

    Its quite common. all ships have heat exchangers. Quite common for some ships designed for the atlantic to have to slow down in certain warm conditions.

    I am not a ship expert but apart from these faulty British Destroyers I have not heard of that happening before.

    The engines actually failed after operating in the Med because the water was not cool enough to keep the engine operating normally... a serious design flaw.

    For most ships I would say a refrigeration unit could be used for cooling water as needed and of course food storage would need freezers to be carried on board too, so it should not be a problem on a well designed ship.

    All you need is large enough heat exchangers for the situation. Temps are monitored closely and they control the flow to the heat exchangers to keep the coolant at optimum temp. If the temps are high even at max flow, then they slow down . A compelete shutdown should is either design or crew incompetence. The problem was most likely with the AC plant as I think those ships are gas turbine powered and those are air cooled. could also have been cruising on diesel gensets.

    It was described as a fundamental design flaw, but OT for this thread.

    The Lider class vid explains a lot. Including why only 1 will first be built. What Russia is doing is essentially investsting 1.7B to see if they can create a Suez Canal alternative. Of course with 1 ship winter capacity will be limited at some time, but if there is demand 2 more will be built. With the Arktika fleet, this is really a historic achievement. The Leider is utterly mindblowing. it can make over 10 knots in 6ft ice !! That is INSANE!!

    The 5th serial hull of the Pr 22220 icebreakers has been laid, but it has been christened as Leningrad rather than Kamchatka.  The 6th hull will apaprently be named Stalingrad rather than the originally planned Sakhalin.

    Interesting that they revert to the Soviet-era name for St Pete?

    Well the region is still called Leningrad oblast even today.

    A cold wind of Soviet nostalgia is blowing across a Russia that uses World War II to justify its war against Ukraine.

    Russia does not need to justify anything to anyone, they have good reason to remember the damage that the nazis did to them in the middle of the last century and have more reason to not forget now that their enemy is using nazi symbology and tactics and are trying to exterminate them again.

    This time they will do a more thorough job of eliminating the threat one hopes, it is sad that the west feels it is OK to tolerate such scum in their agenda to destroy a former ally because they think they are getting too big.

    The city of St. Petersburg was called Leningrad from 1924 to 1991.

    The region is still called the Leningrad Oblast.

    Typical of westerners to think they have to right to tell Russia what they can name their ships... it is good that it upsets them.

    They might be shocked to find there is a US ship called the Alamo... wonder what the Mexicans would think about that name for that ship?

    And that third article about the butt hurt Americans whining because the Russians are fitting guns to their ice breakers... well no surprise really... of course a bully is going to get upset if his victims start to arm themselves and make his fun more dangerous for him.

    Thick and rich from NATzO prats to yap about Russians "using WWII as a pretext". These are the same clowns who attack anyone that
    does not goose-step to their agenda as being in the same camp as Hitler.

    Russia's justification is the events of the last 30 years. The apartheid imposed on ethnic Russians in the Baltic statelets and the open
    plans by the Kiev regime to ethnically cleanse the Donbass along the lines of Croatia's operations Flash and Storm with the same full
    NATzO backing. NATzO is Russia's "pretext". Russia has full rights to engage in right to protect missions. This is exactly what
    the SMO is.

    or Japanese about the USS Iwo Jima & Lybians about the USS Tripoli.

    Naming the new ships the same as the old is common- there was also the ASW helo carrier Leningrad in the Soviet VMF, & Stalingrad-class battlecruiser project.
    In Soviet history, a significant number of ships have carried Stalin’s name. Including in the Arctic. In 1938, the Soviet Union commissioned the icebreaker Stalin, which was in operation until 1973. It was renamed Sibir in 1954. https://thebarentsobserver.com/en/arctic/2023/11/shadow-strife-and-aggression-descends-arctic-putin-names-new-icebreaker-stalingrad
    These old names r part of their history, just like the names of long dead Russian tzars & admirals/generals/heroes, both Russian & Soviet, that they give to their new ships & subs.

    The whole point is the one you said: who the fuk are the people who will tell Russkie how to name their ships?!?
    "Leningrad" name was asked to commemorate thousands and thousands of victims who fell in a time of Leningrad siege.
    Putin's brother, to begin with.
    And the name was asked by the public.
    Icebreaker has all the markings, including the Hero order of a hero city, and the frontal facade of a conning tower with paintings representing the city monuments and searchlights covering it.

    The Russians could call their next frigate "Abraham Lincoln" or "Lil´ Gay Killer" and nobody could do anything about it.

    ... commemorate millions of victims... civilians in millions and soldiers in millions defending that city.

    Maybe Russia should name some of her ships after huge battles in WWII.
    Like Berlin. Very Happy

    I have something even better!
    They should name those after the most iconic examples of the eternal friendship of Anglosaxons towards Germany.
    Dresden, Kassel, Darmstadt, Wuppertal, Hamburg ... would be great.
