I don’t understand how the Fitzgerald “screams of crew fatigue” yet in the case of the McCain the fatigue can be easily managed. If that’s the case why wasn’t fatigue on the Fitzgerald managed better?
You’re right, both ships had fatigue issues.
The McCain was executing a known difficult transit, and had briefed that they were planning on entering the traffic separation scheme at 0500, then entering port in Singapore. They could have(should have) managed their entire day around this, to include sleep schedules the night before.
The Fitz fucked this up as well, but worse. They got underway early in the morning the previous day, trained and did scenarios all day, then had stuff going at night. The comprehensive report states that the 2200-0200 watch had not been allowed to sleep prior to taking the watch, despite having been awake since early the previous day.
The McCain team had at least had some rest since the incident took place later, and they were coming off a normal underway schedule instead of transitioning from in-port to at-sea.
