What is your point exactly? The cost of Canadian defence programs has no relevance to this discussion. Am I to get this thrown in my face every time I initiate a discussion about another country's defence programs?
When you cast judgement perhaps? To be fair to the antipodian and Moderator friend, it was in response to, which has a point I would like to respond to.
I see two problems with that suggestion: Firstly, I would not foresee a scenario where the RCN would be willing to get the first batch of an advanced new design sub (which Attack most definitely is), even from an experienced sub builder, which ASC is not. Secondly, at a cost of somewhere between 4.1 and 6.7 Billion per boat (based on a construction cost of $50-80 Billion) these are way too expensive. (The RCN has reputedly estimated a cost of $20 Billion for 6-8 subs, or 2.5-3.3 billion per.). That cost would even give pause to the USN. At this point I don't believe there is a realistic chance of the RCN becoming a user, which is truly unfortunate.
Hopefully these subs get built, but I see significant technical and financial headwinds ahead for this program.
Every advanced submarine program has significant technical and financial issues (UK, France, Canada, Australia, Russia, China, Brazil, Argentina etc). You take on as much as you can carry. Sometimes, you even fail completely. Lots of countries have had to wind back very ambitious programs (Soviets, US, etc) reduce capability (UK getting rid of conventional) some have given up on submarine capability (Denmark for example).
The Attack class reflects the needs and ambitions and priorities of Australia. Which is why it won out over more conservative designs (such as the German and the Japanese). I can't fathom any "middle power" being willing to take on such an ambitious program. Particularly with its priority focus on range, transit and projection. Japan has a large submarine program, but its totally conservative, very evolutionary, and based around immediate defense not globally projecting power.
Admiral Sammit openly gives out these numbers relating to the cost of the program, and will stare at you eye ball to eye ball when securing these funds. These figures aren't coming from documents that are hidden under FOI or such things, they are openly discussed in public sessions where the media is invited along. Australia is also curious in how open our defence programs are, particularly our submarines.
The costs are reflective of the ambitions of the program. I agree it will be difficult. But they can and will be paid for. This is not a flight of fancy. The 12 subs were proposed by a labor government, selected and paid for under a liberal one. The previous submarine program was again a joint affair (although mostly executed under a Labor gov). Its big heavy stuff, and probably contributed to leadership spills, but regardless of the political idiots in the circus at Canberra, the project moves forward and fires are lit under designers and constructors.
It looks more certain now that we aren't just building 12 new submarines, but we are likely fully modernizing our existing 6 Collins class.
Looking from a Canadian perspective it probably looks impossible. There would have to be an urgency, funding, commitment, a bipartisan agreement, and a public will never seen in any Canadian program (defence or otherwise).
That is a key and central difference between Australia and most other western nations, particularly when it comes to defence. Due to our isolation, there is a much more determined effort and a need to make things work.
