'To see the complex navigation system aboard the USS John S. McCain is to wonder how any amount of training would have been enough for sailors to have been confident using it. ProPublica reconstructed the McCain's Ship Control Console based on the system’s technical manual, confidential Navy reports, a safety review by the National Transportation Safety Board and interviews with a former Navy technician who worked on the system. Screens reflect ship parameters just before time of crash from the NTSB and internal Navy report which called the system “unstable,” with “multiple and cascading failures regularly.” in August 2017, the crew steered the ship toward a naval base in Singapore, where technicians were waiting. The navigation system had indicated more than 60 “major steering faults” during the month. The McCain never reached its destination.'
