The Gatac Railen (Ng.at’ak Sanrailen) is a cargo spacecraft released in 2951 and developed by Gatac Manufacture (Ao't.o'a'Ng.at'ak) for the Human and Xi’an markets. Development of the Railen began after the Human-Xi’an Trade Agreement (HuXa) was passed by the United Empire of Earth (UEE) government in 2947. In addition to a weapons system and armored hull designed to protect the ship in dangerous areas of space, the Railen is equipped with habitation facilities suitable for both Xi’an and Human crew.
