Build:Firing Arcs
9.4 Firing Arcs (Beam Weapons)
Cost: Varies (see table)
Power Requirement: none
All beam weapons have a firing arc (and missile—not torpedo—launchers), which defines the shape and size of the area they “cover” (i.e., can fire into). The larger the firing arc, the more SUs it costs, as defined by the accompanying table.
Some firing arcs possess substantial “arc shadows” which interfere with their ability to fire into an area they normally could. For example, a beam weapon mounted on the aft of a saucer section might not be able to fire at a target “behind” one of the ship’s nacelle pylons. At the Narrator’s option, a weapon which suffers from a substantial arc shadow may reduce the SU cost of its firing arc by 1.
