Orca,
Fully agree, but they can share the load with Raleigh who also have the school of sea survival, complete with DRIU and Fire school. I just read the ditty for Pheonix and they quote 9,000 students for various courses a year, so between them the provision of damage control and fire fighting should be covered.
As you said, the training isn't a "nice to have", it's essential, so keeping your guys current has been part of pre-embarkation training for years now, also one of the reasons the WAFUs join in with the "workup" phase for a ship.
I expect the light blue customers will soon find a nice hotel near each base so they don't have to stay in that awful military accommodation!
Sorry couldn,t resist
Cheers now
