Figherbeams were planned to be incorporated under the proposed tertiary system... I say "system" rather that "weapon", since you don't necessarily have to mount a weapon in it. There's a list of the proposed tertiary devices in the SCP forum, but I think that fighterbeams should have the ability to be used either as a primary, or as a tertiary. The two would be differentiated by their tracking ability, or lack thereof as the case may be. If its a primary, then it would be the straight dumbfire as normal primaries, though tertiary beams would be able to lock on target like an aspect seeking missile. If this were implimented, it could do wonders for campaigns that include gunship style craft that use only beams. In the case of the Star Trek mods, the forward poloron beam of the Dominion Attack ship should realy be capable of target locks. These should however, retain the ability for dumbfire, since you don't HAVE to have a lock to fire.
Later!
