Plasma Defense Array (Apocalypse)
The Marsec version of the defense array uses more powerful and accurate plasma beam weapons to defend against missile attacks. From: Apocalypse Ufopaedia
Plasma Defense Array
This weapon is a anti-missile defense system. It does not fire on hostile crafts and does not use ammunition.
The Plasma Defense Array supercedes the Laser Defense Array by having much better firepower. It's better in every way, and thus should take preference over the Laser Defense System unless budget constraints prevent this.
Refer to the Laser Defense Array section for the weapon particulars.
Because it is of much lower power output than a Lineage, Rendor or Multi-Plasma, the Plasma Defense Array is kitted with an efficient Elerium power plant resembling the ones used in the first alien war. It is effectively as self-sufficient as a Laser weapon, and thus does not require ammunition.
