It’s been a few years since last I was at sea but I recall “losing the load” to be an unfortunately frequent occurrence. It’s a very unsettling experience to find yourself in a silent, completely dark metal box that is moving around under you. Mr. Flashlight was my friend.
My daughter served on a supply tender that tended to lose power at odd moments.
I found it rather appalling this ship was also ordnance resupply for the carrier group.
