The Battlestar Valkyrie was smaller and more maneuverable than the Galactica. It served during the First Cylon War, and was part of the ghost fleet that we saw in  Blood and Chrome.

Richard Livingston originally designed the Valkyrie for the episode Home, where it appears briefly in a flashback sequence. His design went through a lot of changes when the model was built by Pierre Drolet, who made it look more like a familiar Battlestar. The Eaglemoss model is just over 10.5". (27 cm) long.
