Even so, the Lockheed program has had more than its share of difficulties. Its costs grew from $4 billion to $11-12 billion, and the launch date slipped from 2002 to 2009, but SBIRS has thus far been viewed as a problem program with no alternative. That status may be changing. First of all, the existing DSP satellites are lasting longer than expected. In addition, C4ISR Journal reports that SBIRS is being scaled back from at least 5 to no more than 3 satellites (and possibly 2), due to technical difficulties that have proven “intractable.” They also note that the U.S. Air Force will seek Congressional approval next year to begin work on a new space-based Overhead Non-Imaging Infrared (ONIR) missile-warning satellite system instead.
