 Battlestar Valkyrie receives, for the first time in the show, a name  from Norse mythology. Greek mythology is present in the show in the  gods and the names of the colonies (inspired in the Zodiac), and  several names for Battlestars (Pegasus) or cities (Delphi, Troy).  The Valkyries are warrior maidens from Norse mythology who rode the  skies on their horses, so Valkyrie seems a good name for a  Battlestar.
