Russia’s state nuclear agency has launched a new icebreaker, Ural, as part of the country’s plans to dominate the newly warming Arctic region. The nuclear-powered ship is one of three new icebreakers commissioned by Moscow to navigate waters choked with sea ice and smash its way through if necessary.
The ship, Ural, is the third in the class of three Project 22220 icebreakers. The ship was constructed by the Baltic Shipyards of St. Petersburg and will be handed over to Rosatom, Russia’s nuclear agency, in 2021. The Project 22220 ships are 173 meters (567 feet) long and 34 meters (111 feet) wide, making them the largest icebreakers ever constructed. The ships displace a massive 33,000 tons, likely due to large ballast tanks built inside the ship that allow it to ride higher or lower in the water as necessary.

Now, this is an Ural icebreaker!!!
Yes, Ruskie, in action!
Note: the outboard side is driven!

I’d trade my airhead 650 for this in a heartbeat!
(Same mother, different brother)Kind of a bastard child?
Seems odd that the prow has no “edge” to it at all. Instead, it is pretty much a hemisphere, which would indicate that rather than “cutting” and powering through the ice, and pushing it away to both sides, this thing will belly up on to the ice and break it down by sheer force of the vessel’s weight. I see no provision for pushing the broken ice to each side, so that a conventional ship would have a path to follow. I hope they TESTED the concept before spending all those rubles.
Probably the same reason the image is mirrored?
'Appears to have an "edge" to me:
And it's "classmate", "Yamal"'s appears to be well--used:
They build this way since 1950s and it proved the most efficient. Look at any nuclear breaker since Lenin class.
Hope you were joking, Nully... '-)
Image flips during publishing happen frequently; doesn't change the fact that the Ural is afloat -- with this platform...
...and the aft platform...
...still attached.
I never, ever joke.
I subscribed to PopSci from the time I was about 7. I quit when it became an environmental and globull warming rag. Ditto with Natgeo.
Quit reading here:
“The Ural, and its two sister ships, are each powered by two RITM-200 icebreakers generating a total of 350 megawatts.”
The author or the proof reader does not have a single clue about the subject.
The wwii carrier my gramps was on, was slightly less than what this icebreaker weighs.
I’d guess it’s some sort of system that hauls the boat in and out of drydock from deep water.
Our USCG Polar Class Icebreakers work on that exact concept, and the props are actually designed to mill the ice through them.
The dynamic is called ‘dolphining’. You dolphin up onto the ice, crush it under the load of the ship, and then mill the ice through the prop.
Normally, we’d use the fuel as the weight. You get to 60 percent fuel capacity and you are too light to dolphin, let alone back and ram.
The Russians went nuclear, because every nuclear asset produces plutonium, and plutonium is worth $5,000 a gram.
Where’s the sidecar?
I meant down at the keel, like the black one has. The front end of the new nuke icebreaker is rounded and has no “crease” in it.
Don’t get excited ... our new ones due 2024 are the same displacement, but not nuclear, and likely lack the swimming pool and sauna found on most Russian nuke breakers.
