10 years to learn their lesson?

Quoting:Navy brass have called the Yorktown Smart Ship pilot a success in reducing manpower, maintenance and costs. The Navy began running shipboard applications under Microsoft Windows NT so that fewer sailors would be needed to control key ship functions.

But the Navy last fall learned a difficult lesson about automation: The very information technology on which the ships depend also makes them vulnerable. The Yorktown last September suffered a systems failure when bad data was fed into its computers during maneuvers off the coast of Cape Charles, Va.

The ship had to be towed into the Naval base at Norfolk, Va., because a database overflow caused its propulsion system to fail, according to Anthony DiGiorgio, a civilian engineer with the Atlantic Fleet Technical Support Center in Norfolk.

“We are putting equipment in the engine room that we cannot maintain and, when it fails, results in a critical failure,” DiGiorgio said. It took two days of pierside maintenance to fix the problem.
