@Quantum Psychosis 2 bombers could take out an gunboat, try some escort next time when you don't want to get pirated. And you said "at the very least, their own bombers." have you saw how many civilians bombers are? Told you 2 bombers should be enought for one gunboat to take it down. What will be the poit of piracy if you are trading in an fortress, altrought that is the point of making RP with escorts, even the NPC's have some escorts with them.
