The drawing for Design 32/7D for the Gamble
class light minelayers and others modified from flush decked destroyers dated June 14, 1944. The vertical colors were specified to be dull black (BK), ocean gray (5-O) and light gray (5-L). This drawing used the profile of a 3-stack, that had one boiler removed in a modification to produce a high-speed minelayer (DM).
A Design 7D drawing was attached to the July 15, 1943, memo to PacFleet for the DD-381 Somers class of destroyers. On August 19, 1943, it appeared for the Fletcher class destroyers. Design 7D was redrawn for the Farragut class destroyers and for the Chandler class high speed minesweepers. This design was also slightly modified and drawn for the Portland class heavy cruisers on March 21, 1944, using three colors and worn by the cruisers USS Portland (CA-33) and USS Indianapolis (CA-35) and it was worn by the battleship USS West Virginia (BB-48).
