Battle Damage or Engineering Casualty (Engine Troubles). Arleigh Burke speed is controlled by two factors, the RPM of propellers AND the pitch of propeller blades. https://en.wikipedia.org/wiki/Variable-pitch_propeller_(marine) https://en.wikipedia.org/wiki/Variable-pitch_propeller_(mari... Obviously this controls steering as well if system isn't functioning properly. In normal situations, computer mostly handles this and single station (Helm) has control over all 3. If computer fails, the pitch control fails or propeller engine fails, this will need to be controlled manually by the crew and workload is too much for single person. Also, in certain situations, like underway replenishment, all 3 control stations may be manned because if there is sudden failure, you need to be quickly able to respond. Also, the problem is touch screen period. This is case where putting iPad instead of levers/switches/buttons is NOT an upgrade. See your car climate control as good example everyone can relate to.
