Today....the US Navy ships have evaporators for making water and Ice Cream machines.....not so the old Navy!
Oh dear! SASless has just reminded me of the old WWII song, sung to the tune of "Anchors Aweigh" and presumably one explanation of how the USN survived before the days of "evaporators and Ice Cream":
There's a rumour 'round the harbour
That the Yanks are going to sea
With a bottle of coca-cola
An a Bloody great tub of ice cream.
With a bottle of coca-cola
And a Bloody big tub of ice cream
Well they're mighty fine lads in harbour
But oh my God at sea......
Jack
