The U.S. Navy is conducting naval exercises in the Arctic as part of Ice Exercise 2011 (ICE-X 2011). The USS New Hampshire and the USS Connecticut are the two submarines participating in the exercises, which have been planned and are being overseen by the Arctic Submarine Laboratory located in San Diego, about as far away from the Arctic as one can get in the U.S!
Crews will practice navigating and surfacing the submarines in icy water. One thing sailors have to watch out for is ice keels, which are created when two icebergs smash into each other, piling downward into upside-down mountains of ice. This website has a good description of ice keels, along with the below illustration. A new subsurface communications system called DeepSiren, designed by Raytheon, is also being tested in the difficult conditions north of 60 degrees. According to Raytheon engineer Steve Moynahan, “heavy acoustic reverberation, changing surface and subsurface contours, and moving and cracking ice floes” make operating conditions different from anywhere else on earth.
With the help from the University of Washington’s Applied Physics Laboratory and members of the Canadian and British navies, U.S. soldiers are building an ice camp 150 miles north of Prudhoe Bay, on a rare patch of thick sea ice. Rear Admiral David Titley noted that finding thick, multi-year ice for the campsite was “difficult this year.” The temporary village includes everything from a mess hall to a command hut. On the Navy Live blog, the Exercise Director of ICEX 2011, Jeff Gossett, said,
“They have really shown how good our Navy people can be, even in circumstances as totally alien as the Arctic.”
The goal of these exercises is to make the Arctic a much less “alien” place to the U.S. military. Captain Rhett Jaehn, ice camp officer-in-tactical-command, observed in an interview with Reuters, “It is critical that we continue to operate and train today’s submarines in the challenging Arctic environment…”ICEX 2011 is the latest in a series of Arctic exercises, which are key to ensuring our submarines are trained and ready to support U.S. interests in this region.”
Though ICE-X 2011 reportedly only cost $3.5 million, the Pentagon’s budget does not allow for another Arctic naval exercise until 2014, despite the fact that such exercises are supposed to occur biannually. This is disheartening news for proponents of a more active U.S. military presence in the Arctic.
The “Navy Live” blog is posting updates on ICE-X. There are pictures, FAQs, and lots of good posts written by various people at the exercises, including engineers, British soldiers, and American soldiers.

The Ukrainian Army has made dramatic strides in the last few weeks. Ukraine’s tactical commanders have outfoxed their Russian counterparts, and by issuing a feint towards the south the UA has been able to earn substantial gains in the north of their country. The impact of these efforts have been compounded by the steady stream […]
In mid-May the Irish political party, Sinn Féin, won the plurality of seats in the Northern Ireland Assembly. Many American readers might not fully understand the significance of Sinn Féin’s political victory- but rest assured that subjects of the United Kingdom and a wide range of political movements the world over have heard the message […]
The first wave of the Russian offensive in Ukraine has fallen short of Russian autocrat Vladmir Putin’s ambitions. Most analysts deduced that Putin had hoped to achieve a decapitation strike of the Ukrainian government- taking Kiev and replacing Ukrainian President Vladimir Zolinski with a pro-Kremlin voice. Kiev has been threatened repeatedly through the course of […]
