Like the Porters, the Somers class were originally built with eight Mark 12 5-inch/38 caliber guns in four Mark 22 single purpose (anti-surface only) twin mounts.
Torpedo armament was increased to twelve 21-inch (533 mm) tubes in three quad mountings on the centerline, but with no reloads.
The Mark 15 torpedo was equipped.
Anti-aircraft (AA) protection was initially provided by two quadruple 1.1-inch machine cannon mounts and two .50-caliber machine guns.
The 1.1-inch mounts were intended to compensate for the 5 inch guns' lack of AA capability; in the 1930s two quad mounts were thought to be sufficient.
During World War II, as with the Porters, the Somers-class main armament was reduced to six guns, with the light AA armament replaced by up to six 40 mm Bofors in twin mounts and several 20 mm Oerlikon guns by also landing a torpedo tube mount.
On most ships four K-gun depth charge throwers were added to augment the as-built pair of depth charge racks.
In Davis and Jouett the main armament was replaced by five dual-purpose guns in two twin and one single mount.
Later in these two, the torpedo armament was eliminated along with two K-guns and one depth charge rack to maximize the number of 40 mm guns at 14, placed in two quad mounts and three twin mounts.
