Report Date April 2, 1992
Report No. IMTEC-92-21
Subject
Summary:

The Navy's $6.1 billion upgrade of the F-14D "tomcat" fighter aircraft is plagued by serious software problems that have caused cockpit displays to go blank and erroneous data to be submitted to the mission computer. In addition, the Navy's approach to testing software development has been inadequate, increasing the risk that serious software defects may still be unidentified. While the Navy is correcting F-14D software problems, the Navy plans to develop and add the deferred software functions to the aircraft before these efforts are completed. This new software depends on the stability and reliability of the existing software. Proceeding with the deferred software development before ensuring that the existing software is reliable will complicate and make it more costly and time-consuming to detect and correct software problems.
