By November 1942, "North Carolina" had an additional Mark 4 and a SG surface search radar added. The normal battleship configuration was present aboard "North Carolina" in April 1944, with SK and SG radars (air and surface search, respectively), a backup SG, and Mark 8s to direct its main battery. All of the Mark 4s remained for the secondary battery, and one of the older Mark 3s was still present, possibly as a backup for the Mark 8s. An SK-2 dish replaced the older SK radar and Mark 12s and 22s superseded the Mark 4s in September of that year. Aside from never receiving an SK-2, "Washington" was the recipient of similar upgrades.
