In December 2023, the United States unilaterally announced a claim to a huge chunk of seabed well outside its internationally-recognized boundaries off the northern coast of Alaska. Does the US have the resources to enforce its claim? And how do its capabilities stack up against those of other major maritime powers? Sputnik explores.The State Department has a problem. Firstly, to legally protect its encroachment on the piece of seabed in the Arctic which it claims as part of its continental shelf, Washington would have to pay lip service to the 1982 United Nations Convention on the Law of the Sea, which outlines the rules for states claiming continental shelves beyond the internationally recognized 200 nautical mile limit. The first rule? Signing and ratifying the treaty, and only ten years after that submitting claims.Secondly, if it proceeds with its continental shelf claims without UN approval, the US would have to be able to protect its claims by the tangible threat of force, including by using ships and aircraft capable of patrolling the area. The US claim announced in December is not expected to create any disputes with Russia, but will overlap with Canada over a piece of the floor of the Beaufort Sea off the Northwest Territories.Unfortunately for Washington, its geopolitical appetites don’t appear to match its capabilities. Not only is its icebreaker fleet surprisingly tiny, but, according to recent reports, its engineers have apparently forgotten how to reliably produce the thick, hardened steel needed to reinforce Arctic-going ships’ hulls.For these and other reasons, including decades of neglect of its existing icebreaker potential, the United States just barely scrapes into the list of top five countries by icebreaker capability.WorldBypassing UNCLOS?

#5: United States

America’s national icebreaker fleet consists of the US Coast Guard’s Polar Star, a Lockheed Shipbuilding-built icebreaker commissioned in 1976, placed in reserve in 2006, and recommissioned in 2012. The 13,500-ton Polar-class vessel is the only heavy icebreaker in the US fleet capable of sustained, independent operations in the thick ice-covered waters of the Arctic Ocean, able to crack through ice an impressive 6.4 meters thick. The USCGC Healy is the other icebreaker operated by the Coast Guard, displacing 16,257 tons full load, plowing through ice up to 3 meters thick in ramming mode, and hailed as America’s most technologically advanced icebreaker. The ship was commissioned in 1999.© Wikipedia / U.S. Coast Guard/DoDU.S. Coast Guard Cutter Healy (WAGB-20) sits approximately 100 miles north of Barrow, Alaska, in order to conduct scientific ice researchU.S. Coast Guard Cutter Healy (WAGB-20) sits approximately 100 miles north of Barrow, Alaska, in order to conduct scientific ice researchBesides that are three smaller icebreakers used by the National Science Foundation, an independence federal agency engaged in research into all non-medical fields of science. Its ships, built in the 1990s and mid-2010s, include the Nathaniel B Palmer, the RV Laurence M. Gould and the RV Sikuliaq. These vessels operate comfortably in between 0.3 (the Gould) and 0.75 meters (the Sikuliaq) of ice. The Gould and the Palmer are typically stationed in Antarctic waters, while the Sikuliaq, an indigenous word meaning ‘young sea ice’, operates off Alaska.The Coast Guard has ambitious plans for expansion, expecting to get three new heavy icebreakers, and three medium ones, in the coming years and decades. Delivery of the first ship of the new fleet has been delayed from 2024 until at least 2027, with the service requesting $125 million for the purchase and modification of a commercially available polar icebreaker built in the USA to bridge the gap as the flagship Polar Star rapidly approaches the 50-years-old mark.© Photo : James BuchananIcebreaking research vessel Sikuliaq in Woods Hole, Massachusetts.

#4: Sweden

Sweden, which does not have direct access to the Arctic from its coast, or any maritime territory above the Arctic Circle, nonetheless maintains an impressive fleet of icebreakers, mostly for patrolling the northernmost waters of the Gulf of Bothnia and in at least one case, a large inland lake. Sweden operates up to seven icebreakers, five of them – the Ale, the Atle, the Frej, the Oden and the Ymer, run by the Swedish Maritime Administration. The Ale is a 1,540 ton escort icebreaker, purpose built in the 1970s to sail in Lake Vanern, situated in southern Sweden about 150 km southeast of the border with Norway.© Photo : Swedish Maritime Administration.Sweden’s Oden icebreaker pictured breaking up thick ice.Sweden’s Oden icebreaker pictured breaking up thick ice.The Atle, Frej and Ymer are Atle class icebreakers, built at the legendary Wartsila Helsinki Shipyard in Finland between 1974 and 1977. These ships are 104.5 meters long and displace 9,500 tons, and feature a dual rudder and dual bow propeller system that can crack ice at thicknesses of between 0.75 and 1 meters. The newest ship in Sweden’s icebreaker fleet is the Oden, a research vessel built in 1988 and originally tasked with escorting commercial vessels. The ship displaces up to 13,000 tons, and can power through ice up to 5 meters thick, with enough capacity to spare for operations in Arctic waters, pending supply support from a friend in the region. Sweden plans to built at least three new icebreakers, with the first expected to be delivered in 2027 at the earliest.© Photo : Marcus BengtssonSweden’s Ymer icebreaker.Sweden’s Ymer icebreaker.

#3: Finland

Finland’s icebreaker fleet packs a surprisingly strong punch, facilitated by the country’s northern geography, and decades of successful shipbuilding cooperation and sales to its neighbors, Sweden and Russia. The country’s fleet, which includes nine major icebreaking ships, plus one icebreaking-capable special-use ship operated by the Navy, includes the oldest ships in this list: The Voima, commissioned all the way back in 1954, and refit in the late 1970s and again in 2016, is classed as an 1A Super icebreaker, enabling it to break up sea ice up to 1.2 meters thick at speeds of 2 knots.© Photo : Pekka JarvinenThe Voima icebreaker, one of the oldest known icebreakers in operation.The Voima icebreaker, one of the oldest known icebreakers in operation.The Urho and Otso-class (two ships each) displace 9,660 tons and 9,222 tons, respectively, and were built in the 1970s and 1980s to operate in Gulf of Bothnia and Gulf of Finland waters, where ice can reach up to 45 cm thick during winter. The Navy-operated ship is called the Louhi, is owned by the Finnish Environmental Institute, and is classified as an oil and chemical spill response vessel. The ship has a 3,450-ton displacement, and can penetrate ice ridges up to an impressive 5 meters thick, while operating at speeds up to 9.5 knots in 1-meter thick ice.© Photo : ILS Oy Ship Design & EngineeringThe Louhi, a unique Finnish multipurpose vessel design by ILS Oy Ship Design & Engineering with impressive icebreaking capabilities.The Louhi, a unique Finnish multipurpose vessel design by ILS Oy Ship Design & Engineering with impressive icebreaking capabilities.

#2: Canada

Canada, Russia’s Arctic neighbor to the north, has an Arctic coastline stretching a whopping 162,000 kilometers thanks to 94 major and 36,400+ minor islands covering a territory of some 1.4 million square kilometers. That makes a large and diverse icebreaker fleet essential for assuring the country’s sovereign claims. Canada’s Coast Guard operates at least 15 icebreakers (about half of them capable of operations in the far north), at least three icebreaker/tug/supply vessels purchased from Sweden, and two offshore patrol vessels with icebreaking capabilities operated by the Navy.The flagship of Canada’s icebreaking fleet is the Louis S. St-Laurent, a massive, 15,324 ton heavy icebreaker commissioned in 1969 and undergoing refits in the late 1980s and 2000, with room for two Bell 429 helicopters onboard and enough space to comfortably supply 46 crew for over 6 months at a time. The ship can break through ice between three and five meters thick, with its ice horn designed to protect the rudder.© Photo : Serg TremblayLouis S. St-Laurent, the flagship and pride of the Canadian Coast Guard’s icebreaker fleet.Louis S. St-Laurent, the flagship and pride of the Canadian Coast Guard’s icebreaker fleet.Other prominent vessels in the fleet include four ships of the Pierre Radisson-class of medium icebreakers, which weigh 8,180 tons fully loaded and can plow through ice a meter thick at speeds up to 6 knots, and the Martha L. Black class – featuring six light icebreakers built in the 1980s weighing about 4,740 tons full load, and operating off British Columbia, Quebec, Newfoundland and Labrador, and Nova Scotia.The Canadian Navy’s icebreaking-capable warships including the HMCS Harry DeWolf and the HMCS Margaret Brooke, which can slash through first-year sea ice up to 120 centimeters thick.© Photo : US Coast GuardHMCS Harry DeWolf on patrol in Dutch Harbor, September 2021.HMCS Harry DeWolf on patrol in Dutch Harbor, September 2021.

#1 Russia

Dwarfing the rest of the countries in this list, with more icebreakers than the rest of the planet put together, is Russia, whose fleet includes about 45 large icebreakers (seven of them nuclear-powered), well over a dozen off-shore icebreaking anchor-handling tug supply vessels, at least seven icebreaking-capable warships, and three research and survey vessels.The nuclear-powered portion of the fleet includes the Yamal, the 50 Let Pobedy, the Taymyr, the Vaygach, and the brand new Project 22220 series Arktika, Sibir and Ural vessels, which were commissioned in 2020, 2021 and 2022, respectively (the fourth ship, the Yakutiya is set to join them this year, while the Chukotka, Leningrad and Stalingrad are expected by 2030). These massive, 173.3 meter-long ships have a complement of 75, helideck and hangar, and are propelled by two RITM-200 175 MWt-apiece nuclear reactors and twin turbo generators, allowing them to accelerate to speeds of up to 22 knots through open waters, or 1.5-2 knots in ice 2.8 meters thick (with the ability to operate in ice up to 4 meters thick at slower speeds).© Sputnik / Aleksander Galperin / Go to the mediabankRussia’s Arktika-series nuclear-powered icebreaker being pulled along by tugs in a shipyard.

The ship’s 127-person crew will be able to operate non-stop for up to 8 months at a time, enough to ensure comfortable year-round for operations through Russia’s Northern Sea Route passage.EconomyWhat is Northern Sea Route and How Can It Turn Russia Into Arctic Superpower?22 May 2023, 19:03 GMTDiesel-powered ships in the Russian icebreaking fleet include the Admiral Makarov, a veteran scientific and supply ship commissioned in 1975, seven ships total of the Kapitan Sorokin and Mudyug-class icebreakers built for the USSR by Finland in the 1970s and 1980s, and the new Project 21900 ships, the Moskva and the Sankt-Peterburg, built in 2008 and 2009, respectively. The latter displace 14,300 tons, and crack through ice up to 1.5 meters. A modernized model of the Project 21900, Project 21900M, has been built from 2015 onward, and includes the Vladivostok, Murmansk and Novorossiysk. Two more, the Arkhangelsk and the Vyborg, are on the way and may be delivered as soon as this year.© Sputnik / Pavel LvovProject 21900M diesel-electric icebreaker Novorossiysk in the harbor in Murmansk.

These vessels are between 133.5 and 141 meters long, displace between 16,200-16,500 tons, and are classed for independent operations through ice between 1.4 and 3.2 meters thick. Scientists the world over owe much of our fundamental knowledge about the most remote regions of the Arctic and Antarctic to Soviet and Russian icebreaking research ship technology, and to the many thousands of researchers and scholars who have worked aboard them over the decades.© SputnikThe Research Expedition Vessel «Akademik Tryoshnikov»The Research Expedition Vessel «Akademik Tryoshnikov»
