A size class is a numerical scale for rating the relative sizes and capabilities of ships. Two different size class ratings have been created for licensed Star Trek works.
FASA[]
FASA's scale comes from its RPG's Ship Construction Manual, and rates ships in terms of their mass in metric tons. It is merely an indicator of size/mass. Combat Efficiency was a separate rating to compare relative combat strengths.
- Class: Mass (mt)
- I: 0-5
- II: 5-15
- III: 15-25
- IV: 25-40
- V: 40-60
- VI: 60-80
- VII: 80-100
- VIII: 100-120
- IX: 120-140
- X: 140-160
- XI: 160-180
- XII: 180-210
- XIII: 210-240
- XIV: 240-300
- XV: 300-350
- XVI: 350-400
- XVII: 400-450
- XVIII: 450-500
- XIX: 500-600
- XX: 600-700
DS9 video game: Dominion Wars[]
The Dominion Wars computer game used a much simpler scale, from Class-1 to Class-5, which was much more specialized towards particular combat vessels:
- Class-1 ships:
- Class-2 ships:
- Class-3 ships:
- Class-4 ships:
- Class-5 ships:
