SPD Roc Nest: Bridge This wide chamber is commanded by an imposing commander's chair on a raised dais. The bridge then descends by steps with large command stations spaced on each of the steps. The command stations are slim, uncrowned half-domes, the hollowed out interiors clustered with control panels and data displays accessible from a swiveling chair. At the aft of the bridge, massive open-air repulsorlifts stand ready to shuttle freight or large numbers of troops to the lower decks of the ship. The fore of the bridge is dominated by floor-to-ceiling transparisteel view ports that look out over the top of the circular battleship.
