Editing Cassin-class destroyer (section)

===Armament===
The gun armament of four [[4"/50 caliber gun|{{convert|4|in|mm|adj=on|0}}/50 caliber]] Mark 9 guns was a significant increase from the five {{convert|3|in|mm|adj=on|0}} guns of the ''Paulding'' class, and remained the standard US destroyer gun armament through the "flush deck" ''Clemson''-class destroyers commissioned through 1921. It reflected the increasing size of foreign destroyers that the ''Cassin''s might have to fight. The [[torpedo]] armament of eight 18-inch (450 mm) [[torpedo tube]]s was an increase of two tubes over the ''Paulding''s.  A factor in the size of the torpedo armament was the [[General Board of the United States Navy|General Board]]'s decision to use broadside rather than centerline torpedo tubes.<ref name=Friedman1/> This was due to the desire to have some torpedoes remaining after firing a broadside, and problems experienced with centerline mounts on previous classes with torpedoes striking the [[gunwale]]s of the firing ship.<ref name=Friedman1/>

The class was probably equipped with one or two [[depth charge]] racks each for [[anti-submarine]] convoy escort missions in [[World War I]].<ref>Friedman, p. 68</ref>
