This drawing is derived from the composite drawing of Design 3D for the Buckley
class destroyer escorts. This is how the standard Buckley
3D drawing could have been used by flipping the port and starboard to apply the port pattern to the starboard and the starboard pattern to the port side. No original drawing or instructions have been found that would have directed painters to paint this reversed pattern. The original standard 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.
