Mk48 is an awfully big fish for a helo.
Yep! Try and load a couple of them on a helo and ... I am not sure it will ever take off ;D.
Now, I don't believe Czech_Pivo is a seaman, so we should cut him some slack.
I also think that many people see the A, for Arctic, but forget the O, for Offshore.
The concept behind the acquisition of the AOPS was combining the RCN's wish for larger offshore patrol vessels to substitute in for the combat vessels (destroyers and frigates) for the support of other departments duties in winter on the Grand Banks or off Haida Gwai (the Old Queen Charlottes islands for those of you who don't update your maps of Canada from time to time ;D) and the Government of the day's fixation of the day of foisting on the RCN Arctic duties in ice. These winter duties off the shores of Canada were too much for a small vessel like the MCDV's which are not meant to work effectively in such harsh weather. Not that there is anything wrong with the MCDV's themselves: They are great little ships for their purpose - which is primarily mine warfare and support for other similar underwater duties - not patrolling offshore in high sea states.
So the idea is: in summer, the AOPS carry out their Arctic duties. Once the ice hardens in, they move South to do Other Departments Support duties in the Canadian EEZ. And that is why you have some on the West coast as well as on the East coast - not because we like to split our assets from one coast to the other (which wasn't so with the aircraft carriers, the cruisers, the DDH's, the O-boats, the diving support ship Cormorant, or the training vessels, to name a few instances of not splitting assets)
The MCDV's will be retained because: (1) they are great little ships for their duty as mine warfare support crafts; (2) they are economical, even as compared to AOPS, for inshore general duties; (3) they have a lot of life left in them; and, (4) they are much more readily available vessels for reserve officers and seamen training.
Finally, regardless of how busy ISL and Seaspan get, there are more than enough small and medium size shipyards in Canada (and very large ones if you include Davie) to compete for and build the next generation of mine warfare crafts when the need arises in 10-15 years.
