The Poseidon Subclass Light Battlestar is an modified version of the Freyja Subclass Light Battlestar which in turn is a subclass of the Valkyrie Class Light Battlestar. While the Poseidon looks similar to the Freyja. it has been modified to be able to launch missile from it's top side. This missile can either hit space based ships, space stations or planetary targets. Origionally, 12 ships of this class were requisitioned but only seven ships were built before the remaining five were canceled.
