A Congressional Research Service report tracks the Coast Guard’s polar icebreaker recapitalization through its Polar Security Cutter (PSC) and Arctic Security Cutter (ASC) programs. A 2023 Coast Guard fleet-mix analysis concluded the service requires eight to nine polar icebreakers — four to five heavy and four to five medium — to perform its Arctic and Antarctic missions in coming years. The current operational fleet is just three vessels: the heavy icebreaker Polar Star, which entered service in 1976 and is well beyond its intended 30-year service life; the medium icebreaker Healy (2000); and Storis, a 2012 commercial Arctic oil-exploration support ship the Coast Guard purchased in 2024 and converted to a medium polar icebreaker. New construction proceeds under the PSC and ASC programs, alongside the trilateral ICE Pact icebreaker-collaboration effort. The report flags oversight issues for Congress, including program-execution risk, the potential effect of a Greenland annexation on the number of icebreakers required, and the use of foreign shipyards for building US vessels.
