The United States' last vessel capable of breaking through the heaviest ice of the Arctic Circle, and resupplying the U.S. polar research station there, is scheduled to leave San Francisco Bay on Tuesday, Nov. 11, 2014. While Russia and China have dozens of icebreakers, opposition in Congress to funding means the U.S. has just one heavy-duty one, already a decade past its decommissioning date.
