This Battle of the Alpha Site, also known as the Battle of New Horizon, took place during the Federation-Lucian Alliance war in 2391 on and above P4X-650, known to the Federation colonists as "New Horizon". The battle saw a Lucian Alliance strike force attempt to invade the planet and draw Federation forces away from Earth. Although the Lucian Alliance forces were routed and destroyed, they succeeded in distracting part of the Federation fleet in preparation for an attack on Earth.
