摘要：	Of the Coast Guard's three polar icebreakers, two Polar Star and Polar Sea have exceeded their intended 30-year service lives, and Polar Star is not operational and has been caretaker status since July 1, 2006. The Coast Guard has begun initial studies on replacements for the two ships. Under the Coast Guard's current schedule, the first replacement ship might enter service in 8 to 10 years. A 2007 report from the National Research Council (NRC) on the U.S. polar icebreaking fleet states that U.S. polar icebreaking capability is now at risk of being unable to support national interests in the north and the south. Congress, in the explanatory statement for the FY2008 Consolidated Appropriations Act (H.R. 2764/P.L. 110-161 of December 26, 2007), expressed concern about the Coast Guard's ability to meet its polar operations mission requirements and directed the Coast Guard to submit a comprehensive report on the issue. The Coast Guard estimates 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. Potential policy issues for Congress regarding Coast Guard polar icebreaker modernization include 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 older ships; whether to accelerate the Coast Guard's current schedule for acquiring replacement ships; whether new ships should be nuclear powered; whether new ships should be funded in the Coast Guard budget or the Department of Defense (DOD) budget; and whether, as an interim measure, the Polar Star should be repaired and placed back into service. / NOTE: Congressional rept. / Supplementary Notes: CRS Report for Congress. / Availability Note: Product reproduced from digital image.
