I am not convinced that there ever was a "Canadian Naval Strategic" outlook or even a golden period of such thought around the 1990's.
What we did have, as the result of the coincidence of the RCN 75th anniversary and arrival of the modern ships (the HALs) that finally let the Navy free itself of its ASW blinders, was a revival of interests in the broader tactical scope of naval warfare in all its aspects and discussions of the RCN's history (pushed as a result the 75th) and future place in the current naval paradigm of NATO and US navies. I would not necessarily call that naval strategy, or an interest therein.
Now, broadly speaking, there are only two naval strategies: Sea Control or Sea Denial. In Canada, both as a faithful ally of NATO and of the US and because it is clearly in our very own interest as a trading nation surrounded by the sea, we are by definition working under a Sea Control strategy.
I believe it was Infanteer who recently brought up (in another thread) Hughes on Fleet Tactics. One interesting point made by Hughes was that naval power is seated, meaning governed, from land. It brings an interesting question: from a naval point of view, where does the distinction between tactics and strategy begin?
Classic case: Battle of the Atlantic. Obviously, the Allies were Sea Control strategists (freedom to use the seas) while the Axis powers were Sea Denial strategist (starve England by cutting maritime access). But does the overall battle, which involved control from shore of organization of convoys, arranging escorts, organizing and coordinating air patrols, then running a hunting campaign in the Bay of Biscay and bombing campaigns against U-Boat lairs, etc., qualify as "strategic" or still "tactical"?
I think two points quickly becomes obvious: First, at the "ship-at-sea" and TF/TG level at sea, everything is tactical - and it must be mastered. Second: It is hard to determine where the line lies between that tactical level and what becomes clearly considered as "strategic".
BTW, and I may make some enemies in my own service here :nod:, It is my firm belief that, at the national level, national defence strategy is and should be the purview of the Army. Such determination then should dictate the naval and air requirements. To give a Canadian instance: If the Canadian Army had decided that there is an actual essential strategic requirement for Canada to have an amphibious capability, then the RCN would have been told to provide it and it would have.
So when I see Army people in these fora complaining that we have no such capability (and this is a pet peeve of mine ;D), I can only think that it is because they, as the Canadian Army, have failed to make a case to our political masters for its necessity.
