In [[Engineering:Naval architecture|naval architecture]], a '''flush deck''' is a [[Engineering:Deck (ship)|ship deck]] that is continuous from stem to [[Engineering:Stern|stern]].<ref>{{Cite web |url=https://docs.rwu.edu/cgi/viewcontent.cgi?article=2772&context=law_ma_jmlc |access-date=2026-02-02 |website=docs.rwu.edu|title=Compatibility of Greater Carrying Capacity with Safety of Life and Property|last=KUSHNER|first=LESTER|url-status=live}}</ref><ref>{{Cite web |last=Network |first=MI News |date=2021-06-10 |title=10 Types of Decks Every Seafarer Should Know |url=https://www.marineinsight.com/marine-navigation/10-types-of-decks-every-seafarer-should-know/ |access-date=2026-02-02 |website=Marine Insight |language=en-US}}</ref>

==History==
Flush decks have been in use since the times of the ancient Egyptians. Greco-Roman Trireme often had a flush deck but may have also had a fore and aft castle deck. Flush decks were also common on medieval and Renaissance galleys but some also featured fore and aft castle decks. The medieval [[Engineering:Brigantine|Brigantine]] and later Brig and [[Engineering:Snow (ship)|Snow]] ships also featured flush decks.

==Two different meanings of "flush"==
"Flush deck" with "flush" in its generic meaning of "even or level; forming an unbroken plane", is sometimes applied to vessels, as in describing yachts lacking a raised pilothouse for instance. "Flush deck aircraft carrier" uses "flush deck" in this generic sense.

"Flush deck" in its more specific maritime-architecture sense signifies that the main deck runs the length of the ship and does not end before the stem (with a separate raised [[Engineering:Forecastle|forecastle]] deck forward) or before the stern (with a separate raised or, as seen on many modern warships, lowered [[Engineering:Quarterdeck|quarterdeck]] rearward). The flush decks are broken by masts, guns, funnels, and other structures and impediments, and are far from being unbroken planes.

==Types==
Flush deck [[Engineering:Aircraft carrier|aircraft carrier]]s are those with no island [[Earth:Superstructure|superstructure]], so that the top deck of the vessel consists of only an unbroken flight deck.<ref>{{cite web | url=https://warshipprojects.com/2020/02/18/warship-projects-profile-jp201-amagi-class-carrier-conversions/ | title=Warship Projects Profile No.JP201 – Amagi class carrier conversions | date=18 February 2020 }}</ref>

"Flush deckers" is a common nickname for a series of American destroyers built in large quantities during or shortly after [[Social:World War I|World War I]] – the {{Sclass|Caldwell|destroyer|5}}, {{Sclass|Wickes|destroyer|5}}, and {{Sclass|Clemson|destroyer|5}} classes – so called because they lacked the raised [[Engineering:Forecastle|forecastle]] of preceding American destroyers, thus the main deck was a flush deck.<ref>{{cite web |url=http://destroyerhistory.org/flushdeck/ |title=Flush Deckers |work=Destroyer History Foundation |access-date=October 20, 2014}}</ref>
