"Scheme "B-I" - Destroyer Study"
Preliminary design plan prepared for the General Board as part of the process leading to the Allen M. Sumner (DD-692) class design.
This 30 September 1941 plan, for a 2135-ton (standard displacement) ship, provides a slightly updated Fletcher (DD-445) class destroyer, retaining its five single 5"/38 gun mounts (two of which are semi-open mounts) but eliminating one bank of five torpedo tubes to achieve a less crowding amidships. Other notable changes are a modified bridge arrangement and two twin 40mm anti-aircraft gun mounts (in place of the single quad 1.1" weapon of the original Fletchers).
The original plan is in the 1939-1944 "Spring Styles Book" held by the Naval Historical Center.
