Naval Pulse Lasers
Availability: Clan 3068
Overview: When Clan Nova Cat was abjured by the Grand Council, one of the few Clans to help them escape were the Snow Ravens. In exchange for assistance the Ravens received certain territories. These territories included a Nova Cat research facility that specialized in energy weapons. The Ravens directed these resources toward improving capital energy weapons. Naval Pulse Lasers are the result but rumors persist that this design team is still working on further improvements.
Game Effects: Naval Pulse Lasers receive a -1 to hit large craft while in addition to being able to strike small fighters with area of affect fire. They receive a +2 to hit however because of the lasers large size. The Pulse Lasers are slightly larger, produce more heat and do slightly more damage than a standard naval laser. There are three different types; 40, 50, & 60.
