 Without providing prior notice of the exercise, officers on "Saratoga" woke the enlisted Sea Sparrow missile team and directed them to conduct the simulated attack.According to U.S. Navy, certain members of the missile firing team were not told that the exercise was a simulation drill, rather than an actual firing event.As the drill progressed, the missile system operator used language to indicate he was preparing to fire a live missile, but due to the absence of standard terminology, the supervisors failed to appreciate the significance of the terms used and the requests made.
