I've always assumed, or at least hoped, drills on a naval ship would be done on a "surprise" basis...
They are, for the most part. Ship-initiated exercises are usually on the whim of the XO (Executive Officer), with the assistance of the Cox'n sometimes. After a while, you develop a sixth sense as to when these types of exercises are thrown at you based on the loose "plan" for the period spent at sea.
All bets are off during workups, when Sea Training (a team of senior personnel representing each department of the ship) is embarked, and their job is to keep you off-kilter as much as possible. Cutting into your sleep time isn't one of their concerns. They're there to train you and nitpick every little fault they can find. Workups are done periodically, roughly once every two years if I recall...though that may have changed with the new tiered readiness programs.
I've always been curious what would happen if a fire were to occur around, say, 0200...
I'm surprised some keen sailor hasn't produced a logic diagram on how to deal with this. At 0200, it would go something like this:
Action alarm sounds - wait until bongs stop
Is it a man overboard? If yes, go back to sleep as on-watch handles it and you shouldn't be in your rack if you're on watch.
If not a man overboard, is it a Verification muster? (to ensure everyone is still on board the ship, and nobody has gone overboard) - If yes, stay in your bunk, because except for absolute critical personnel, that's where everyone on the ship goes to get counted.
Is it Action Stations or Emergency stations? (combat, fire, flood, collision) If yes, get out of your bunk because you're going to be getting dressed and will be up for a while. Other extra details: Pay attention to the announcement as to where the fire is, so that you don't inadvertently go through it on the way to your Emergency Station (yes, it happens when you're half asleep and not thinking, but it's highly frowned on for obvious reasons)
Is it Emergency Flying Stations? If yes, and you're sleeping in the messdecks in the after end of the ship, get out of your bunk and get dressed very, very quickly. There will be a very loud and cranky PO or CPO coming into your mess to awaken you and get you out of the mess as fast as possible, because there may possibly be an 18,000 lb helicopter crashing above you at any moment.
It's been quite a few years and I'm sure I've forgotten many of the other possible branches on the logic diagram, but you get the drift.
