What would a more realistic Imperial Navy sector fleet require?
Short answerKeep major capital ships and add many more frigates, corvettes, and other escort assets so heavy units are not misused for routine local tasks.
NotesAn Imperial sector force built around capital ships alone would leave routine missions uncovered. Smaller escorts are needed for jobs that fictional stories often assign to a Star Destroyer, such as pursuing a corvette. The historical analogy is that an escort force can be numerous yet still inadequate for the tasks expected of it. Combat power includes the ships that screen, patrol, and handle dispersed demands as well as the largest hulls. Another panel member notes that supporting Star Wars material includes numerous escorts, while the reply distinguishes having many from having enough.
