I know the air is compressed when they flood the tanks, but I'd assume that some power is needed to blow or regulate ballast, just from a mechanical standpoint

I know the air is compressed when they flood the tanks, but I'd assume that some power is needed to blow or regulate ballast, just from a mechanical standpoint of opening and closing doors.
I'd be surprised if there were no backup generators at all. Maybe not in the front, but somewhere where the primary backups aren't. Shit happens.
- mpyne 13y agoCompressed air can be directed wherever it needs to go by installed piping and valves, and the valves themselves can be hand-operated. Submarines do indeed carry an emergency diesel generator, and they also have a fairly large battery, but the emergency main ballast blow system can be run off of nothing but previously-stored energy and a hand-actuated valve.
