It's canon not cannon. And anyways it's called using your eyes and that the Akira class was in a sense a "torpedo cruiser".
Unless one can actually count fifteen torpedo launchers on the vessel, there's no reason to accept that information as fact. Also, given that you were the one whining about how you were treated last week, you're not doing yourself any favors by mouthing off or rolling your eyes at me. Knock it off. Or do you still want that beating I promised you?
What part of my earlier notices did you not understand? Knock off the ass-beating and other threats. Enjoy your day off.
