The drawing for Measure 32 Design 3D for the Allen M. Sumner
class destroyers as dated February 29, 1944.
The vertical colors were specified to be dull black (BK), ocean gray (5-O) and light gray (5-L) and the horizontal colors were ocean gray (5-O) and deck blue (20-B). Haze gray (5-H) could have been used in place of light gray to be Measure 31.
An almost identical version of this design was issued on July 28, 1944, also in Measure 32 colors.
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.
