The drawing for Measure 32 Design 18D drawn for the North Carolina class battleships possibly dated August 1943. This drawing used the colors of dull black (BK), ocean gray (5-O) and light gray (5-L) vertically with a pattern of deck blue (20-B) and ocean gray (5-O) on the horizontal surfaces. The North Carolina actually used a slightly different version of this design probably from another drawing which is yet to be found.
Design 18D was derived from an earlier pattern suggested in the June 1942 revision to SHIPS-2 to be used with Measure 16 introduced by that document. A Design 18D drawing was attached to the July 15, 1943, memo to PacFleet for the Fletcher class destroyers. Design 18D was dated December 1943 when drawn for the Baltimore class heavy cruisers and it was worn by USS Canberra (CA-70), USS Quincy (CA-71) and USS Pittsburgh (CA-72). The battleship USS North Carolina (BB-55) also wore Design 18D from November 1943 all the way through 1944.
