            The Honorable John P. Murtha
            Chairman, Subcommittee on Defense
            Committee on Appropriations
            House of Representatives

            Dear Mr. Chairman:

            This letter responds to your request that we review the
            Department of the Air Force's acquisition of the Granite
            Sentry system--one of five subsystems comprising the Air
            Force's Cheyenne Mountain Upgrade program.'
            Specifically, you asked that we provide cost and schedule
              information on Granite Sentry, as well as information on
              the system's ability to satisfy the Department of
              Defense's attack warning and attack assessment
              requirements. To provide this information, we obtained
              documentation from and interviewed program officials at
              the Air Force's Electronic Systems Center, Hanscom Air
              Force Base, Massachusetts; U.S. Space Command and Air
              Force Space Command, Colorado Springs, Colorado; Carnegie
              Mellon's Software Engineering Institute, Pittsburgh,
              Pennsylvania; and Mitre Corporation, Bedford,
              Massachusetts.

              BACKGROUND

              In 1981 the Air Force began several projects to replace
              aging and obsolete computers at Cheyenne Mountain Air
              Force Base. These computers are used by the North



              1 The five subsystems are the (1) Communications Systems
              Segment Replacement, (2) Space Defense Operations Center
              4, (3) Command Center Processing and Display System
              Replacement, (4) Survivable Communications Integration
              System, and (5) Granite Sentry. A back-up system--the
              Alternate Processing and Correlation Center at Offutt Air
              Force Base in Nebraska--was added in 1989 to provide
              missile warning and air defense information should the
              system at Cheyenne Mountain fail.
