Just a short video, made at least a couple of years ago, but particularly wanted to feature the “cable deck,” time 1:27 to 1:45, where you see mooring and anchoring gear conspicuously missing from the foc’sle. Keeping this gear inside the ship is critical to keeping it operational in the Arctic environment.
A total of eight ships of the class are planned, six for the Canadian Navy and two for their Coast Guard. Navy or Coast Guard, these “Arctic Offshore Patrol Ships” (AOPS) essentially perform what we view as Coast Guard missions. They are 6,615 ton ships, 340 feet (103.6 meters) in length. Four diesel generators provide power to two electric motors that provide 12,000 HP for a 17 knot max speed. Range is 6,800 nautical miles at 14 knots. The crew is 65 with accommodations for 87. The gun seen in the video is a weatherized version of the 25mm Mk38. They are Polar Class 5.

Do we know what Polar Class equivalent the Article Security cutter will be yet?
Polar class 5. Means it can break 6 ft ice at 5 knots or something like that without coming to a stop. The Coast Guard’s best ice breakers are class 4. They have two class 2 on order. I think only The Russians have class 2 now. Class two can break ice up to 10 ft thick. Class 1 is over 10 ft and none have ever been built anywhere. My understanding anyway.
@Grant, I get the impression you are talking about the Canadian Coast Guard. I believe Dale’s question was about the USCG Arctic Security Cutter.
@Dale Sale. The short answer is no. We have not seen any specs or even a request for information. We probably should have built the medium icebreakers first since it should have been the easier ship.
The Coast Guard definition for a “medium icebreaker” would mean at least 20,000 HP, so significantly more than the Canadian AOPS.
