Her home port is Seattle, Washington. In addition to these duties, Polar Sea also serves as a scientific research platform with five laboratories, additional space for seven portable laboratories on deck and accommodations for up to 35 scientists. The report was submitted in November 2013 and indicated that it is feasible to retrofit and reactivate Polar Sea. Vice Commandant Adm. Charles Michel says the only choices for continuing the icebreaker missions are either restoring Polar Star while in service or reactivating Polar Sea, at a to be determined cost; this estimate is due in early 2017, so at that time lawmakers will likely decide the ship's fate. this design does not use sharp edges or hammer-like blows to cut or break the ice, as the round bow and massive weight are sufficient. It has not been determined if a new class will be funded, commercial icebreaker leasing options will be explored, and/or if the ship should be scrapped.[11]. [13] For years, having only one working heavy icebreaker hindered the Coast Guard’s ability to satisfy mission requests from government agencies effectively.
