This is the composite of the two drawings of Design 3D for the Buckley class destroyer escorts probably drawn up no later than November 30, 1943 since they were sent to DE-699 on that date. These drawings used “open” colors, so the colors would be dull black (BK), ocean gray (5-O) and the lightest color was light gray (5-L) for Measure 32 and haze gray (5-H) for Measure 31. The drawings also show a whaleboat on both port and starboard views. Reversing the bare starboard drawing and adding colors afterward probably produced the port view. The original starboard drawing included a plan view that indicated all decks and horizontal surfaces should be deck blue (20-B) with no pattern. Note the stern view showing the aftermost panels on either side viewed edge on.
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.
