This is a list of icebreakers and other special icebreaking vessels (except cargo ships and tankers) capable of operating independently in ice-covered waters. Ships known to be in service are presented in bold .
Prior to ocean-going ships, ice breaking technology was developed on inland canals and rivers using laborers with axes and hooks. The first recorded primitive icebreaker ship was a barge used by the Belgian town of Bruges in 1383 to help clear the town moat.
During the 2004–2005 season (Operation Deep Freeze 2005), the United States Antarctic Program hired the Krasin as a secondary vessel to help clear a channel to McMurdo Station [7] because the Coast Guard icebreaker Polar Star faced a record cut through fast ice of more than 90 miles (140 km).

The 6-metre (20 ft) wide ice belt, where the hull plating was over 50 millimetres (2.0 in) thick in the bow, was designed to withstand ice pressures of up to 1,000 tonnes per square meter (about 1,400 psi), more than 30 to 60 times as much as normal merchant ships at the time.
That includes the medal-round ice hockey match at the 1980 Winter Olympics in Lake Placid, New York between the United States and the Soviet Union. This Saturday, Feb. 22, is the 45th anniversary ...
In addition to her ice-breaking duties, the Mackinaw also serves as an Aids-to-Navigation ship, since she is able to perform the same duties as the Seagoing Buoy Tenders (WLB) of the Coast Guard fleet. Further, she can conduct law enforcement and search-and-rescue missions and can deploy an oil-skimming system to respond to oil-spill situations ...
