Melting ice in the Arctic is creating opportunities for access to oil and gas, and shipping lanes. But the area is still mostly frozen and navigating the inhospitable region on top of the world still requires an icebreaker, the heavy duty ships that are able to crash through massive layers of ice.
The U.S. Coast Guard is responsible for search-and-rescue missions, as well as protecting the environment and defending U.S. sovereignty. The U.S. is one of five countries with territorial claims to the land and waters of the Arctic (The others are Canada, Russia, Norway and Denmark.).
The problem is, the Coast Guard doesn't have enough icebreakers, says Shiva Polefka, an Arctic specialist at the Center for American Progress.
"At present, we have one heavy icebreaker that's capable of accessing all corners of the Arctic year-round," he says.
That vessel, the Polar Star, was built in the 1970s and was designed to last three decades. It's now in its 40th year and showing its age.
But at least it's still operational, Polefka says, unlike its sister icebreaker, the Polar Sea.
"The Polar Sea had a major engine breakdown in 2010, had to be towed into its home port of Seattle, and it's basically been ... just rusting in the docks in Seattle," he says.
There is another, smaller icebreaker used for scientific research, but it doesn't have the capabilities of the Polar Star.
Having just a single, old heavy icebreaker at a time when other countries are jockeying for position in the Arctic weighs heavily on Adm. Paul Zukunft, commandant of the U.S. Coast Guard.
"Russia has approximately 27 ocean-going icebreakers. ... Some of those are nuclear-powered," he says. "And so we're not even in the same league as Russia right now."
Canada, Finland and Sweden all have more icebreakers than the U.S.
China — hardly what you'd call an Arctic nation — recently commissioned its second icebreaker. India is in the process of acquiring its own.
Zukunft says a major study found the U.S. needs six new icebreakers — three heavy and three medium — to carry out the Coast Guard's increased missions.
Zukunft says he'd be happy with just one new one right now. But he's unlikely to get that any time soon.
"My acquisition budget for this year is $1.1 billion to buy new stuff," he says. "That would be one icebreaker and nothing else."
The Coast Guard falls under the Department of Homeland Security, which has a tiny budget compared to the Pentagon, says Polefka with the Center for American Progress.
As a comparison, Polefka says, the Navy intends to spend about $20 billion per year for the next 20 years to build new ships.
"Yet the Navy says explicitly in their strategic planning documents that they depend on the Coast Guard to access icy waters. The Navy has no icebreakers of their own," he says.
But neither the Pentagon nor any other U.S. agency has stepped up to pay for even one icebreaker.
Malte Humpert, the executive director of the Arctic Institute, says that's likely because of uncertainty about what is going to happen in the Arctic. There are questions about how fast the ice will melt and whether it's worth investing in heavy polar icebreakers. He says it's not like acquiring a destroyer or frigate, which can be used anywhere in the world.
"You can really just use it in the Arctic for very specific purposes, and the Arctic is not the current main theater of engagement," Humpert says. "Everything is shifting towards the Pacific and the Arctic is only the tertiary theater."
Humpert says the Arctic doesn't have the same strategic importance to the U.S. that it does to other northern nations. He says one-fifth of Russia's GDP is generated above the Arctic, and 40 percent of its future oil and gas lies under the frozen waters.
"So from that perspective, it makes a lot more sense to build icebreakers to gain access to open the shipping lanes and so forth," Humpert says.
Coast Guard Commandant Zukunft doesn't buy that argument.
"Our GDP is at least eight times that of Russia. And yet we say we can't afford an icebreaker," he says. "We just need to make it a priority."
The Polar Star — the only U.S. heavy icebreaker in use — is expected to reach the end of its life by 2020. After that, the Coast Guard may need to rethink its motto of semper paratus, Latin for "always ready."
