Drawing 32/23D for the Benson class destroyers dated March 18, 1944, using the profile of Bancroft (DD-598). This two-color design used dull black (BK) and light gray (5-L) for the vertical surfaces.
Design 23D was derived from a Measure 16 pattern dated June 1942. The design drawing for Buckley class destroyer escorts was dated March 8, 1944. Design 23D was drawn for Mahan class destroyers on April 13, 1944, and again for Admirable class minesweepers on May 5, 1944. Also on May 18, 1944, the Design 23D drawing was reissued for the destroyer Cassin, rebuilt after Pearl Harbor, but both starboard and port bow patterns had been extensively modified even though the design number remained the same; there is no evidence whether Cassin used this modified design.
