We had racks, with “all hands heave out and trice up” as a reminder of hammock days. My ship was built in 1940; I served aboard from ‘61 through ‘64, so she was well broken in.
As the Navy continues to modernize, I am not sure that some of the old traditions don’t have a place, if only to enforce discipline.
Someone else noted that discipline seems lacking after boot camp.
I can see the efficiency of flying troops home rather than a troopship, but the cost must be higher (as it is in freight).
It is almost as if the modern Navy doesn’t care about $$ anymore, just whiz bang and high tech.
At some point though, someone has to steer, someone has to keep the boilers going and someone has to fight fires.
