FIGURE 5.1 Current formal Navy requirements for PTTI, as compiled for the committee by N70T. Not included are the classified programs, some of which presumably are pushing the state of the art in PTTI. Forty-three programs are shown (some points overlap).

  • The needs of homeland defense, including information security, locating homeland jammers, and tagging and tracking terrorists,

  • The reduction in overseas bases and subsequent increased reliance on long-range support, and

  • The increased need for data fusion and time correlation of events to allow a glut of data to be transformed into useful information.
