Four [[destroyer]]s in the [[United States Navy]] comprised the '''''Cassin'' class'''. All served as convoy escorts during [[World War I]]. The ''Cassin''s were the first of five "second-generation" 1000-ton four-stack destroyer classes that were front-line ships of the Navy until the 1930s. They were known as "thousand tonners" for their normal displacement, while the previous classes were nicknamed "flivvers" for their small size, after the [[Model T Ford]].<ref name=1000tondh/>

They were the first to carry the new [[4"/50 caliber gun|{{convert|4|in|mm|adj=on|0}}/50 caliber]] guns. The number of [[torpedo tube]]s was increased from the six carried by the {{sclass|Paulding|destroyer|4}} to eight. The additional armament significantly increased their tonnage to over 1,000 tons and decreased their speed to less than {{convert|30|kn|lk=in}}, despite an increase from {{convert|12,000|shp|kW|lk=in}} to {{convert|16,000|shp|kW|abbr=on}}.<ref name=Register1/>

The {{sclass|Aylwin|destroyer|4}} was built concurrently, and those four ships are often considered to be ''Cassin''s. Both classes were ordered in [[fiscal year]] 1912.<ref name=Register1/><ref name=Conways1/><ref name=Friedman1/>

The class performed convoy escort missions in the [[U-boat Campaign (World War I)|Atlantic]] in [[World War I]]. Hulls 43–45 served in the [[United States Coast Guard]] as part of the [[Rum Patrol]] in 1924–31. All were scrapped 1934–35 to comply with the [[London Naval Treaty]].<ref name=Conways1>Gardiner and Gray, pp. 122–125</ref>
