| 5 | DS9 | 6 | Valiant | Stated in the to be twice the size of a Galaxy class ship. This is assumed to mean twice the length, rather than twice the volume. Note that battleships of this design seen in the DS9 finale appeared to be approximately 4.5 kilometres long compared to Dominion battlecruisers. |
| 6 | Speculative | Based on several comparisons made to the Dominion Battlecruiser in What You Leave Behind. Note that the Dreadnoughts appearing in this scene may be Dominion Battleships rendered larger than their true size due to poor special effects. | ||
| 7 | Speculative | |||
| 8 | Speculative | A tricky one - I can find no reference to the length of this ship anywhere. I measured the distance between two rows of windows on the picture and assumed three metres per deck to scale the drawing, and calculated the length from that. There is likely to be a fairly significant degree of error in this figure. | ||
