The Hail Mary currently. Just such a cool ship from a fun book. To think about what would go into building it and what that means to humanity is humbling.

Other notables:

• Enterprise E from First Contact because it looks cool.
• Cygnus from The Black Hole
• Sulaco from Aliens
• Trimaxion Drone Ship from Flight of the Navigator
• The Abominator-class Offensive Unit Falling Outside the Normal Moral Constraints (my usual favourite lol)
