The drawing for Design 32/18D for the Fletcher
class destroyers dated March 21, 1944. This drawing also used the square bridge profile and the stern view did not show any pattern on the hull. An earlier drawing dated August 18, 1943, (80-G-156814 and 80-G-156815) used the round bridge profile and did not show the turrets, but did show the stern. The stern view from that drawing is shown in the inset at upper left. There were two versions of the stern.
Design 18D was derived from an earlier pattern suggested in the June 1942 revision to SHIPS-2 to be used with Measure 16 introduced by that document. A Design 18D drawing was attached to the July 15, 1943, memo to PacFleet for the Fletcher class destroyers. Design 18D was dated December 1943 when drawn for the Baltimore class heavy cruisers and it was worn by USS Canberra (CA-70), USS Quincy (CA-71) and USS Pittsburgh (CA-72). The battleship USS North Carolina (BB-55) also wore Design 18D from November 1943 all the way through 1944.
