Starship classification

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

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:
 * Dominion Jem'Hadar fighter
 * Cardassian
 * Klingon
 * Federation Defiant- and Saber-classes


 * Class-2 ships:
 * Dominion Jem'Hadar strike cruiser
 * Cardassian
 * Klingon
 * Federation


 * Class-3 ships:
 * Dominion Jem'Hadar battle cruiser
 * Cardassian
 * Klingon
 * Federation


 * Class-4 ships:
 * Dominion Jem'Hadar warship
 * Cardassian Defiant- and Saber-classes
 * Klingon
 * Federation


 * Class-5 ships:
 * Dominion Jem'Hadar super carrier
 * Cardassian
 * Klingon
 * Federation
