The SSD-0001 Magellan (which was referred to by SpetsNaz and Chinese special operatives as a "flying battleship") was the first and only ever space warship created by the United States Space Administration. It was armed with eight batteries of railgun, but burned up in Earth's atmosphere when the skipper purportedly lost control over the ship.

The Magellan as envisioned by the designers. Note that there are more and smaller railgun batteries scattered throughout the ship, which were scrapped from the final design.
