Canada and its Possible new submarine

[Kapitan]

Canada has announced recently that it intends to replace its ageing Upholder / Victoria class submarines.

Just thinking aloud here in what the design requirements and specifications will be for the replacement submarine (they haven't been published publicly yet) I think it will be safe to say there will be a few key areas Canada wont want to budge on.

1) Must be built and Maintained in Canada (Unless Domestic building cost prohibitive the latter requirement is likely to take precedent)
2) Reasonable cost per unit
3) have long open ocean endurance (60-90 days)
4) Be conventional or AIP
5) Be a proven design likely already in service
6) Capable of having the American Lockheed fire control suite
7) Have the ability to fire MK48 torpedoes, Mines and ASM Missiles (likely Harpoon at this stage)
8) Have a life span of 40 years


With this in mind I think there are only a few real contenders in the making those being:

Japan Soryu class
German Type 212CD
Sweden A26
France / Australia Barracuda

Given the issues with the French design and handling with the current Australian requirement I would give that bid a medium chance of getting through, Canada has more ties with France that is for sure but could the current Franco-Australian problems put them off?

Sweden has a good design in the A26 yes they have an ocean going variant for possible export which is larger than the initial A26 but they have no buyers, Denmark was a joint partner in the early 2000's but ceased submarine operations in 2004.
Also the early debacle with the Australian Collins class may put a dampener on things.

Japans Soryu class fits the bill it is probably the most superior submarine of them all, they are fairly expensive per unit, the key issue is while these submarines are available for export (it ran in the Australian bid) Japan is reluctant to have them built outside Japan (This is why the Australians didn't select the boat)

Germany Type 212CD a much larger variant of the type 212 is currently being built for Germany and Norway, very capable submarines and they can be built outside of Germany, personally I think this design would be the winner as Canada routinely operates with the Norwegian navy.


I would like to know what you think folks is there another design out there ? one that may clinch the deal?
