The drawing for Design 3D for four-stack destroyer classes with Measure 32 colors dated July 26, 1944. This drawing was labeled "1200 Ton Class" but could be used by any flush- deck destroyers and modifications. The vertical colors were specified to be dull black (BK), ocean gray (5-O) and light gray (5-L). The horizontal colors were ocean gray (5-O) and deck blue (20-B).
A Design 3D drawing was attached to the July 15, 1943, memo to PacFleet for the DD-380 Gridley class of destroyers. Design 3D was also drawn for every other class of destroyers and destroyer escorts and for most other classes of major warships including the Independence class light carriers, the Casablanca class escort carriers, Omaha class light cruisers and Cleveland class light cruisers. The battleship USS Colorado (BB-45) also used Design 3D beginning in October 1943. A handful of ships of the Livermore class of destroyers and some destroyer escorts used a mirrored version in which the port pattern appeared on the starboard and the starboard pattern was painted on the port side. I have identified this as 3D rev (reversed) even though there seem to be no USN drawings that would depict this.
