The Polar 8 Icebreaker is a type of vessel used by the Canadian Coast Guard and Canadian Forces Maritime Command for patroling the Arctic Circle. The Polar 8 Icebreakers started construction in 2004 with a unit run of two icebreakers (named John G. Diefenbaker and Roald Amundsen) originally. In 2005, the Roald Amundsen was renamed the Robert Stanfield after the April 2005 death of 16th Prime Minister Robert Lorne Stanfield. In 2006, a second pair of Polar 8 Icebreakers were ordered (named John Edward Broadbent and Roald Amundsen). The Polar 8-class are the largest icebreakers in the world coming in at 575 feet in length and 45,000 tons displacement.
