The Hesperus was two or three hundred feet in length, shaped like a sort of fish or bird-like creature, with the bridge in the head. It had a structure like a dorsal fin on top, which appeared to be used for stabilisation in a planet's atmosphere. It had two other fins angled on its underside. It had thrusters in the rear and rows of yellowish lights running along the head. (TV: The End of Time)
Though not intended for combat, the Hesperus was armed with asteroid lasers to blast away meteoroids and asteroids. These lasers proved sufficent to destroy human-made missiles as the ship came under attack from the Master Race. (TV: The End of Time)
Behind the scenes
- The name Hesperus was never used in-narrative. Instead, it derives from the script for The End of Time. 
- The ship bears similarities to Red Dwarf's Starbug One.
