The icebreaker ships, moving and navigating through ice-covered waters, require features such as a strengthened hull, an ice-clearing shape, great momentum and the power of a robust engine to push through the frozen land.
Ice breaker ships are of utmost importance in ice-clad regions, wherein waterways need to be made accessible by clearing off the layers of ice.
Here are the top 10 biggest icebreaker ships that rock the world.

10. USCGC Polar Sea (WAGB-11)
Constructed by Lockheed Shipbuilding and Construction Company of Seattle and even though commissioned in 1977 this is one of two world’s most powerful class of non-nuclear icebreaker ships and is still in service. The Polar Sea boasts of a displacement of 13,194 long tons, a length of 399 ft, and the ability to progress through 6 ft of ice at 3 knots.
It carries a crew of 24 officers, 20 chief petty officers, and other 102 engaged. This icebreaker ship owns four sizable lounges, a library, a gym, and a small ship’s store. It also has the amenities of its own U.S. Post Office, satellite telephones, radio equipment, photo lab, movie library, etc. It serves as a scientific research platform with its onboard laboratories concerning fields of geology, vulcanology, oceanography, sea-ice physics, and other disciplines.
9. RRS Sir David Attenborough
The Royal Research Ship or RSS Sir David Attenborough is an ice-class research vessel for the antarctic region operated by the British Antarctic Survey. It also serves the purpose of logistic supply in the region. The ship is built to carry two helicopters and has a cargo capacity of 900 cubic meters. The overall length of RRS Sir David Attenborough is 423ft and has a beam of 79ft. It is built with accommodation for 30 crew and 60 research staff.
8. Kapitan Dranitsyn
Kapitan Dranitsyn is another Russian icebreaker in the top 10 list. It has been modified as a passenger vessel with a capacity to carry 100 passengers equipped with public accommodations with spacious lounges, bars, library, and other recreational facilities.
Its overall length measures approximately 423.3ft with a beam of 87.1ft. It is powered by 6 wartsila-sulzer engine producing an overall power of around ~18,000
Shirase is a Japanese icebreaker ship and one of the four Antarctic icebreakers operated by Japan’s maritime self-defence force. The ship is 452.9ft long with a beam of approx. 92ft. Driven by four diesel-electric motors it produces a combined power of 22,000KW. It can carry 8- scientists and 1,100 tons of cargo
Shirase icebreaker is equipped with a unique auxiliary icebreaking system which consists of holes on the bow of the ship through which it sprays water to wet the snow accumulated on the ice, which makes the ice easier to hold and thereby improves the icebreaking effect.
6. Viktor Chernomyrdin
Viktor Chernomyrdin is another Russian icebreaker that was outfitted at Admiralty Shipyard in Saint Petersburg.
She is the largest and most powerful diesel-electric-powered icebreaker built in Russia having four diesel engines of 8,700kw each. With an overall length of 482 ft and a beam of 94 ft, it displaces 22,000 tons with a draft of 28-31ft.
Yamal is a Russian nuclear class icebreaker ship operated by Atomflot. The name of the ship ‘Yamal’ means End of the Land in Nenets.
Yamal has the capacity to carry one helicopter and several Zodiac boats. It is equipped with amenities such as a large dining room for 100 passengers in one sitting, a library, passenger lounge, auditorium, volleyball court, gymnasium
