Many spacecraft have only a basic comm/sensor array (see Control Room), but some have more sophisticated systems. This is a large multi-function sensor and communications array. It uses an embedded phased array or rotating antenna for communicators and sensors. Installation of more than one array is rare, except for specialized space observatories or intelligence spacecraft. There are four types:
Enhanced Array: A larger and more capable version of the basic array that comes with a control room system.
Science Array: Incorporates highly sensitive instruments for use in astronomical and physics surveys, as well as the same equipment as an enhanced array.
Tactical Array: Has the same capabilities as an enhanced array, but adds the ability to actively jam transmissions and overcome defensive ECM.
Multipurpose Array: Combines science and tactical array functions.
All arrays integrate active sensors, passive sensors, and a comm suite into a single system. The array is rated for its type and comm/sensor array Level, based on SM and TL, e.g., an SM+8 spacecraft built at TL9’s Level is 8. The array level is the same for all types; the only differences are their special abilities. The comm/sensor level determines the Telescopic Vision level of the array’s passive sensors.
The rules have a table to show level, but the formula is: At SM+5 Array Level=TL-4; the level improves by 1 for each size class increment. In the Dominion, most ships are built at TL 9 so the Array Level equals the Size Modifier.
An Enhanced or better array gives +2 over the Basic Array that comes with the Control Room module.
