The DDS have now begun field trials of the next step, PSVA 2.0, which increases the area a PSVA group can cover up to 1 light year. PSVA 2.0 also integrates active sensor data from other ships and base stations further afield to provide sensor resolutions equal to or even greater than the information one ship could provide for itself using active sensors. This means a cloaked ship can get a highly detailed tactical view without the risk of betrayal using active sensors. The DDS could also use a ship with very powerful active sensors out of harms way to "illuminate" the combat zone.
PSVA 2.0 support is a software only upgrade and is being rolled out to ships this week.
