Coast Guard Polar Icebreaker Modernization: Background and Issues for Congress

Ronald O'Rourke

The Coast Guard’s proposed FY2013 budget includes $8 million in acquisition funding to initiate survey and design activities for a new polar icebreaker. The Coast Guard’s Five Year Capital Investment Plan includes an additional $852 million in FY2014-FY2017 for acquiring the ship. The Coast Guard anticipates awarding a construction contract for the ship “within the next five years” and taking delivery on the ship “within a decade.” The project to design and build a polar icebreaker is a new acquisition project initiated in the FY2013 budget.

Coast Guard polar icebreakers perform a variety of missions supporting U.S. interests in polar regions. The Coast Guard’s two existing heavy polar icebreakers—Polar Star and Polar Sea— have exceeded their intended 30-year service lives, and neither is currently operational. Polar Star was placed in caretaker status on July 1, 2006. Congress in FY2009 and FY2010 provided funding to repair it 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; the ship was unavailable for operation after that. The Coast Guard placed Polar Sea in commissioned, inactive status on October 14, 2011, and plans to decommission it in FY2012.

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 reactivation of Polar Star and the decommissioning of Polar Sea will result in an operational U.S. polar icebreaking fleet consisting for the next 7 to 10 years of one heavy polar icebreaker (Polar Star) and one medium polar icebreaker (Healy). The new polar icebreaker for which initial acquisition funding is requested in the FY2013 budget would replace Polar Star at about the time Polar Star’s 7- to 10-year reactivation period ends.

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 numbers and capabilities of polar icebreakers the Coast Guard will need in the future; the disposition of Polar Sea following its decommissioning; whether the new polar icebreaker initiated in the FY23013 budget should be funded with incremental funding (as proposed in the Coast Guard’s Five Year Capital Investment Plan) or full funding in a single year, as required under the executive branch’s full funding policy; whether new polar icebreakers 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; whether to provide future icebreaking capability through construction of new ships or service life extensions of existing polar icebreakers; and whether future polar icebreakers should be acquired through a traditional acquisition or a leasing arrangement.
