Coast Guard polar icebreakers perform a variety of missions supporting U.S. interests in polar regions. The Coast Guard’s two heavy polar icebreakers—Polar Star and Polar Sea—have exceeded their intended 30-year service lives, and neither is currently in operational condition. The Polar Star was placed in caretaker status on July 1, 2006. Congress in FY2009 and FY2010 provided funding to repair Polar Star and return it to service for 7 to 10 years; the Coast Guard expects the reactivation project to be completed in December 2012. On June 25, 2010, the Coast Guard announced that Polar Sea had suffered an unexpected engine casualty and consequently would likely be unavailable for operation until at least January 2011.
The Coast Guard’s third polar icebreaker—Healy—entered service in 2000. Compared to Polar Star and Polar Sea, Healy has less icebreaking capability (it is considered a medium polar icebreaker), but more capability for supporting scientific research. The ship is used primarily for supporting scientific research in the Arctic.
The Coast Guard’s FY2012 budget proposes decommissioning Polar Sea in FY2011 and transitioning its crew to the reactivated Polar Star. The resulting U.S. polar icebreaking fleet would consist of Polar Star and Healy.
A 2007 report from the National Research Council (NRC) on the U.S. polar icebreaking fleet stated that “U.S. [polar] icebreaking capability is now at risk of being unable to support national interests in the north and the south.” The Coast Guard has stated since 2008 that it is studying how many polar icebreakers, with what capabilities, it will need in the future.
Following any decision to design and build one or more new polar icebreakers, the first replacement polar icebreaker might enter service in 8 to 10 years. The Coast Guard estimated in February 2008 that new replacement ships might cost $800 million to $925 million each in 2008 dollars, and that the alternative of extending the service lives of Polar Sea and Polar Star for 25 years might cost about $400 million per ship. In August 2010, the Commandant of the Coast Guard, Admiral Robert Papp, reportedly estimated the cost of extending their lives at about $500 million per ship.
Potential issues for Congress regarding Coast Guard polar icebreaker modernization include the potential impact on U.S. polar missions of the United States currently having no operational heavy polar icebreakers; the length of time that the Coast Guard has been studying requirements for polar icebreakers; the numbers and capabilities of polar icebreakers the Coast Guard will need in the future; whether to provide these icebreakers through construction of new ships or service life extensions of existing polar icebreakers; and whether new ships should be funded entirely in the Coast Guard budget, or partly or entirely in some other part of the federal budget, such as the Department of Defense (DOD) budget, the National Science Foundation (NSF) budget, or both.
