No. 28 Icebreaker, U.S. Eastwind
The icebreaker has perhaps done more than any other machine to make large scale AntarcHc exploration possible. United States Navy icebreakers can cut channels through ice up to 15 feet thick through which cargo ships can follow. In spring Operation Deep Freeze icebreakers break up to 50 or 60 miles of channel in McMurdo Sound to allow in the first cargo convoy.
