Main gun battery: 4 x dual purpose 5-inch/38 caliber guns: 2 forward in enclosed base ring mounts; 2 aft in open pedestal mounts.

The two ships of the Dunlap class, Dunlap and Fanning, were funded in fiscal year 1935. They repeated the Mahan design to the extent that many sources list them as part of the Mahan class. They differed in the introduction of base ring mounts for the forward 5-inch/38 caliber guns, which permitted the projectile hoist to rotate with the gun, simplifying handling for the gun crew and allowing for slightly more rapid firing. Accordingly, these forward guns were enclosed by gunhouses of a general design that continued in use through the Fletcher class, and in Cold War frigates through the Garcia and Brooke classes.

United Shipbuilding built both ships at Staten Island, New York. As completed in 1937, they lacked the Mahans’ tripod foremast and pole mainmast; as modified during World War II, they appeared very similar to the Mahans.
