The .50 caliber machine guns did not have the range or power needed to combat modern aircraft and were scheduled for replacement by equal numbers of 20 mm guns, but nothing immediately came of the proposal. In fact, both "North Carolina" and "Washington" carried 20 mm and .50 caliber guns for most of 1942. In April, "North Carolina" had, respectively, forty and twelve, while "Washington" had twenty and twelve. Two months later, the number of 20 mm guns remained the same, but twelve .50 caliber guns had been added. By September, "Washington" had twenty more 20 mm guns added, for a total of forty, but five were removed—along with all of the .50 caliber guns—shortly thereafter when two quadruple sets of 1.1 in guns were added. In its refit after being torpedoed, "North Carolina" had an additional six 20 mm guns added and all of its .50 caliber weapons removed. "Washington" had sixty-four 20 mm weapons by April 1943, prior to one single mount being replaced by a quadruple mount, and "North Carolina" had fifty-three by March 1944. In April 1945, "North Carolina" was assigned to have fifty-six 20 mm, while "Washington" was assigned seventy-five. In August 1945, the ships both had eight twin 20 mm mounts; "North Carolina" also carried twenty single, while "Washington" carried one quad and sixty-three single.
