Flush deck

Flush deck is a term in naval architecture. It can refer to any deck of a ship which is continuous from stem to stern. It has two specific common referents:

• Flush deck aircraft carriers are those with no island superstructure, so that the top deck of the vessel consists of only an unbroken flight deck.
• "Flush deckers" is a common nickname for a series of American destroyers built in large quantities during or shortly after World War I – the Caldwell, Wickes, and Clemson classes – so called because they lacked the raised forecastle of preceding American destroyers, thus the main deck was a flush deck.
