Sweep maximizers are specialized against fleets of destroyers, since if the base turret only aims at a decoy ship. Explosive missiles and torpedoes fired at decoy ships attempting to draw fire, will spread out over a wide area at long areas and could hit a line of destroyers, the destroyers are more fragile hence decoy cruisers draw away fire. They are particularly effective for Plasma torpedoes. They are relatively uncommon weapon boosters. They have no effect on explosive weapons with no spread.
