If they're not able to go the Arctic due to ice conditions or the season, I don't have an issue with them going south as ships tied up doesn't do anybody any good. After all, the ability to deploy south was built into them. I agree that we should have at least several in the Arctic for the max amount of time, however the RCN doesn't see it that way apparently. If they didn't pay off the Kingston Class prematurely we could still be sending ships on Caribe and freeing the AOPV's up for other missions.
At the back of my mind, for a number of years now, I have bothered by a comparison between the AOPS and two of the Coast Guard's fleet: the Leonard J. Cowley and the similar John P. Tully.
They are 70m craft.
They are ice-strengthened.
They displace about 2000 tonnes.
They have a max speed of 14 knots.
They have a range of 12000 nm and an endurance of 35 days.
They support light helicopter operations.
They have crews of 20.
They support a DFO law enforcement det.
Machine guns were fired across the bows of the Estai from the Cowley during Peckford's Turbot War.
Two points:
That description sounds a lot like the Continental Defence Corvette.
Vard is the designer of the Cowley.
Cowley seems to spend her life on the Grand Banks and the Labrador Sea.
....
Canada's Arctic is an extension of the Atlantic. Apparently even the Beaufort Sea ice from over by Tuk and the MacKenzie delta flows into the Atlantic.
Cowley sails out of St John's.
Year round.
6 AOPS sailing out of St John's, in place of the Cowley, could easily spend their entire career in the Northwest Atlantic, on the Grand Banks, the Labrador Sea, Davis Strait, Baffin Bay and Nares Strait - following the ice, tracking commercial shipping, supplying SAR and disaster assistance AND supporting the anti-submarine effort. They would effectively act as gate guards to the eastern entrance to the Northwest Passage.
And, following the ice, they could penetrate the Northwest Passage to Tuk and perhaps even overwinter there. Similarly they could follow the ice into Hudson Bay and Churchill, again overwintering possibly.
That would provide an enduring presence in the Arctic compatible with both Canadian needs and NORAD wants and the RCN could back burner the effort and focus their River Class / Continental Defence Efforts on ships designed for ice-free waters.
And by following Coast Guard manning practices they would only be using half the manpower.
