Screw the beer.
Bring back the grog ration.

Of course aircraft carriers are not strictly 'dry'. Aviators are allocated one or two shots of liquor after every landing. Many ships stock similar 'medicinal' supplies that are allocated as called for. More recently the entire crew of an aircraft carrier got a beer ration after being deployed for eight or nine months.

On an interesting historical note the term 'Dutch courage' came from the Dutch practice of issuing rum when enemy ships were sighted and battle was deemed likely. Sailing ships would often take hours, or even days, to close and conclude the nerve wracking sailing contest of maneuver for advantage. The rum was said to steady the nerves and instill a sense of unity and camaraderie.
