CCGS Henry Larsen is a Canadian Coast Guard T1200 Class Medium Arctic icebreaker serving in the Newfoundland and Labrador Region and based in St John's, Newfoundland.[1]

A "Medium Gulf/River Icebreaker", the vessel is named after Henry Larsen, the commander of the Royal Canadian Mounted Police patrol vessel St. Roch which was the first vessel to traverse the Northwest Passage in a single season.

The Canadian Coast Guard has two vessels in their "Heavy Icebreaker" class, and four in the "Medium Gulf/River Icebreaker" class. These are their only vessels capable of year-round operation in the high Arctic. These vessels all have a helicopter hangar and can carry and maintain a Bo 105 helicopter, which is used for logistical purposes, as well as ice-spotting, and search and rescue.

A 2004 voyage of this vessel is the subject of the documentary film "Ice Breaker".

In 2008 Discovery Channel filmed an episode of *Mighty Ships on Henry Larsen as she did an ice patrol around Notre Dame Bay of Newfoundland.

In September 2009 Henry Larsen participated in a training exercise with the Danish vessels HDMS Ejnar Mikkelsen and HDMS Hvidbjørnen.[2]

The ship can operate on just one of its three Wärtsilä VASA 16v32 engines, and then add a second or third engine as the thickness of the ice warrants. Thicker ice requires more power, but that means the engines will require more cooling. Even in such a cold environment, however, cooling those engines can be problematic.
