Subsequently, a stationary observer can only detect a vessel one light-year away when its light arrives at the observer's location, one year after leaving said vessel.īecause faster-than-light attackers always arrive before defenders can detect them with luminal sensors, attackers can always surprise defenders.
Sensors, unlike ships and communications employing the mass effect, are limited to the speed of light. The most important role filled by frigates is reconnaissance. Unlike larger vessels, frigates are able to land on planets. They often have extensive GARDIAN systems to provide anti-fighter screening for capital ships, and carry a squad of marines for security and groundside duty. Frigates are light escort and scouting vessels.
