Draconia is the flagship of the Draconian Empire in 2491 CE. The ship is one of many of King Draco's star fortresses.
While on a fake mission of peace to Earth, Princess Ardala and the ship's commander, Kane, use Draconia to launch Hatchet fighters to disrupt the Earth's food supply lines. This faux peace, along with the deployment of Hatchet fighters, is a prelude to invasion.
En route to Earth, Hatchet fighters intercept Ranger 3 and its preserved occupant, Captain William "Buck" Rogers, bringing the 500 year old relic to Draconia. After reviving and debriefing the occupant, as well as fitting the ship with a transmitter, Ranger 3 and Rogers depart from Draconia en route to Earth.
Rogers is able to infiltrate the ship and later aid in its destruction, thwarting the Draconian Empire's plans (BR25: "Awakening").
Other Draconia-type star fortresses are later used by Princess Ardala, suggesting that this is a primary ship class in the Draconian Empire's fleet (BR25: "Escape from Wedded Bliss", "Ardala Returns", "Flight of the War Witch").
Launch Bays
Snub superiority fighter crafts, such as the Hatchet fighter, launch from irregular pentagon shaped tubes connected to an interior hangar bay deeper within the ship.
Landing Bays
Smaller crafts are received in a landing bay.
In the case of Ranger 3, a tractor beam is employed to bring the unpowered relic aboard (BR25: "Awakening").
Ardala's Chamber
Princess Ardala's chamber is quartered aboard, featuring various amenities of opulence, including a large bed and make-up station. These chambers feature a recessed floor from the main entry (BR25: "Awakening").
