  JTAGS
  A-6. JTAGS detachments are subordinate to the 1st Space Company, Theater Missile Warning, 1st Space
  Battalion. Each detachment consists of a headquarters and five crews. Two detachments with overlapping
  coverage are needed to support the JTAGS mission for 24-hour per day operations over extended periods
  (ATP 3-14.5). Each unit has three external high-gain, eight-foot dish antennas. JTAGS is presently a
  transportable information processing system, housed in a standard military shelter, that receives and
  processes in-theater, direct down-linked data from Defense Support Program satellites. Using existing
  communication networks, JTAGS disseminates near-real-time warning, alerting, and cueing information on
  ballistic missiles and other tactical events of interest throughout the theater to combatant commanders and
  BMDS for the protection of military assets, civilian populations, and geopolitical centers. Figure A-3 on page
  A-4, shows a JTAGS in a field setting.
  A-7. JTAGS is currently being upgraded to a new configuration for operation with the next generation of
  the Space Based Infrared System and to improve warning accuracy and timeliness. Improvements include
  information assurance upgrades, new commercial antennas, SIPRNET capability, and the integration of five
  systems from shelters into operation centers.
