Devices are special one-shot ship that are deployed in a specific sector to produce a given effect.  All empires start the game with the necessary technical details for constructing these devices, and are limited only by their cost.  All devices have a single DP so they must be well protected.  A device is destroyed when it is deployed.
 

• inertial damper -- This devices disables the engines of all ships in one sector for one turn.  Ships in the affected sector have an effective engine rating of zero for that turn, and any movement orders issued for the affected ships are cancelled.
• ion generator -- This devices generates an ion storm in the affected sector for one turn.  Ion generators can be deployed in the same sector as existing ion storms or in tandem with other ion generators.  In such cases the ratings of all ion generators and existing ion storms are added together to increase the storm's damage rating for that turn.
• pocket nebula -- This device produces a nebula-like effect in one sector for one turn.  As with true nebulae, ships within the affected sector have an effective scan rating of zero, and no ships outside that sector can scan within it.
• pollution bomb -- This reduces production of a world to zero for one turn.  The world's production increases to half its normal value (rounded up) on the next turn, and then returns to its starting value the turn thereafter.
• portal hammer -- This devices causes a wormnet portal in the affected sector to collapse for one turn.   Any movement orders that would normally go through this portal are cancelled.
• storm shield -- This devices prevents ion storm damage to all ships in one sector for one turn.  Each starbase is equipped with a permanent storm shield that is always active.  Note that a storm shield does not cancel the scanner interference effect of ion storms.  It simply effectively reduces the storm rating to zero.
• warpdrone -- A warpdrone is a special device that creates a temporary wormnet portal connected to any other warpdrone portals created by the same empire.  Only the owning empire and its allies can use warpdrone portals. Warpdrone devices are not destroyed when they are deployed; rather the temporary portal lasts as long as the warpdrone exists.  If the warpdrone is destroyed, its portal collapses immediately, and any pending movement orders through that portal are canceled.  Warpdrones can be loaded onto carriers and moved to other sectors.  The temporary portal moves with the warpdrone, even while it is loaded.  Warpdrones cannot be deployed in or carried to sectors containing worlds or existing portals; in such instances, the temporary portal collapses until the warpdrone moves elsewhere.  If multiple warpdrones are moved to the same sector, all of their temporary portals collapse until only one warpdrone is present in that sector.  Warpdrone portals (but not the warpdrones themselves) are susceptible to portal hammers.

 
 
A device deployed in the same sector as an operational starbase (friendly or otherwise) will not function (but will be destroyed nonetheless).
