This paper model is the Cloud 9, a massive, FTL-capable luxury liner within the Fleet, based on the American military sci-fi television series Battlestar Galactica, the papercraft was created by Steve.
Extensively damaged during the Cylon attack, it had to be evacuated while repairs were made. Following the repairs, it is returned to full service within the Fleet, and provides a venue for the first sitting of the interim Quorum of Twelve convened by President Roslin.
The ship is unique in that as well as traditional living and working space on board, Cloud 9 incorporates a huge pressurized dome, that provides a realistic simulation of a planetary surface, including gardens, buildings, trees, and even an artificial holographic sky. Not only does the dome make this ship more luxurious, but the comfortable hotel rooms, as well as the enjoyable lounges and bars, make this ship popular and well-known to the survivors.
Cloud 9 is also unique in the fact that it is one of the few fleet ships with an asymmetrical design. The ship is split into a long, slim main section that houses the ship's landing bay, numerous hotel suites, and the sublight engines, while the massive dome is connected off the starboard side via a small connecting walkway. This design makes it impossible for Cloud 9 to attain atmospheric flight, as the forces involved would tear the ship apart. [Source: BS Wiki]
