Federation Vs Empire debate

This is a cool program i found

by this calculator a full power phaser from the Enterprise D at optimal range could destroy an asteroid made of nickel iron with a diameter of 850 meter depending giving a Galaxy class star ship a firepower of 4.5 megatons

While one energy bolt from an ISD can destroy the same type of asteroid with a diameter of 591 meters that would take 1.5 megatons of energy

now just because an ISD's weapons are 2 1/3 that doesn’t mean the Empire is out of the fight I’ve calculated the total fire power of an ISD at somewhere around 42 megatons (28 TL's) where as a Galaxy class got about 36 megatons (8 phaser arrays)
