Who said the fusion plants are going to be used to power the LAC? Modified micro-fusion plants to provide the plasma for the ETorp launcher. Is that so difficult to understand?
You did. To quote your words:
Jesus! Am I talking to kids here? ETorps Launchers for Missile launchers and missiles. Either replace the Fission file with a not so micro fusion plant or mate the fusion plant directly with the ETorp launcher. ITS AN ENGINEERING PROBLEM. One that Manticore has the capability to do. They have micro fusion plants in drones for crying out loud!
Do not yell at me when you are the one who is saying stupid things.
Yes, the sidewalls may still be active, but you still have that big damned graser in your LAC's nose, use it. The current LACs mainly use their missile power at the start of their attacks and flush what's remaining when they see an opening for it. Their main weapon for taking down the enemy ship is the graser, which will remain. What they're getting would be a coup de grace weapon that would enable them to finish off a target quickly so they can move on to another target. With the current weapons mix, LACs have to pound the enemy into scrap with their grasers. With ETorps if one or two sidewall generators goes down, just a couple of salvos will turn that ship into a wreck freeing the LAC to find another target.
Energy torpedoes are dead weight in all but a few scenarios. So why are you so insistent that LACs haul around that dead weight all the damn time when the graser is already more than enough to do the job? If the situation is so far up shit creek that the ship has lost its sidewalls completely, then the graser is already plenty enough to do the job to compel the enemy to surrender. A sidewall-less SD is in for a world of hurt from a Shrike's graser, so there is absolutely no reason to put energy torpedoes on them.
For that matter, those "useless" LAC missiles you're stripping out would also be plenty useful against such a foe, because there is no sidewall to mitigate the damage.
