With all due respect, despite the designer's intentions for that many torpedo launchers to cover so many lateral fields of fire (and hey, what about targets above/below the Akira?), I can't really see a whole lot of space for torpedo magazines in the primary hull when a lot of that internal space is needed to support shuttlecraft/fightercraft operations. Unless, that is, the torpedoes are already stacked up in the tube nose-to-rear, a la Metalstorm. Even then, photon torpedoes are very maneuverable and it doesn't make much sense from my viewpoint to install all of these unnecessarily redundant launchers. A torpedo pod that has multiple launchers covering fore and aft should be able to spit out enough torpedoes to keep a threat occupied quite handily.
