In July 2007 Canadian Prime Minister Stephen Harper announced plans to construct six to eight Arctic Patrol Ships for Canadian Forces Maritime Command. These vessels were initially announced to be based on the Norwegian Svalbard class. The vessels were projected to cost $3.1 billion CAD to construct, and $4.3 billion was projected to be required for maintenance over the vessels' 25 year lifespan. The first ship in the class is expected to be delivered in 2014.

Project History

In 2006 Prime Minister Stephen Harper had spoken about building 3 to 4 heavy arctic icebreakers capable of traveling through thick ice. In 2007 it was announced that the Canadian Navy would purchase 6 to 8 Arctic Polar Class 5 patrol ships capable of ice breaking. This announcement was met with some controversy, and the proposed ships have been called "slush-breakers", by Dr. Gary Stern, a scientist aboard CCGS Amundsen, and Jack Layton of the NDP. However, it is notable that of the 19 Canadian Coast Guard icebreakers currently in service, only 6 have a polar ice class equivalent that is higher than Polar Class 5.Cite error: The <ref> tag has too many names (see the help page).

Design

The vessels' design was initially intended to incorporate a conventional icebreaking bow for cruising, and would have proceeded backwards for breaking heavy ice. The vessels' stern would have been designed for ice breaking and they would have employed azipods for propulsion and for chewing through resistant ice. However, due to cost constraints, a conventional bow-first design was chosen for both light and heavy icebreaking. The propulsion would be provided by diesel-electric twin shafts with bolt on propellers, similar to existing Canadian Coast Guard icebreakers.

The vessels would have a hangar and flight deck capable of employing and maintaining the same maritime helicopters as Maritime Command's other vessels, the CH-148 Cyclone when it enters service, and the similar sized Canadian Forces Search and Rescue CH-149 Cormorant.

In 2008, a contract was awarded to BMT Fleet Technology and STX Canada Marine to assist in developing technical specifications and a design for the project. The technical specifications will be used to draft a Request for Proposals. It is likely that project implementation will begin when the contracts are expected to be awarded in August of 2010.
