Each autocannon will eat 1500 energy per second when local power is drained, which happens after like 5 seconds of firing. That means to continue firing, you'd need 1.5 generator cores per each continuously firing weapon. That means if you think that 28 autocannons will end up being fighter class firepower, your fighters will need at the very least 45 (42 for weapons, 3 for moving this chonker) reactor cores. Each reactor core being 1x1x1 meters, or 1 cubic meter in volume, you'd need a generator of over 45 cubic meters to support your fighter-class ship. Now that's not even counting the fuel rods, coolant racks, socket boards and enhancer modules. In conclusion of my wonderful calculus-level mathematics, 28 autocannons is far from being able to fit in a fighter.
