Yes, sir. Thank you very much for the question.
I would say that four is the minimum. It follows from the previous class of submarines. This is the second class of submarine that the Royal Canadian Navy is operating. Previously, we also ran for Oberon class submarines. We have taken the establishment that we had to man, train, and operate four submarines and projected that forward with the Victoria class.
Given the Canada First defence strategy, given the investment plan that underpins it, given the fiscal environment we find ourselves in, I would not advocate for more submarines. However, I am very comfortable with the four we have. I'm very, very excited to see that we're at that end of the long beginning.
