This is the drawing for Measure 32 Design 3D for the Doyen class attack transports of (P1-S2-L2) maritime type hull dated January 27, 1944. The vertical colors were specified to be dull black (BK), ocean gray (5-O) and light gray (5-L) with deck blue (20-B) for the horizontal color. The colors for the boats was also shown on the side views.
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.
