The drawing for Design 32/18D for the destroyer USS Chew and others dated July 25, 1944. The vertical colors were specified to be dull black (BK), ocean gray (5-O) and light gray (5-L). This drawing used the profile of a 3-stack, that had one boiler removed usually a modification to produce a high-speed transport (APD).
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.
