"Scheme "B-II" - 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 2200-ton (standard displacement) ship, introduces the twin 5"/38 dual-purpose gun mount as a destroyer weapon. Three of these are provided, as well as two twin 40mm anti-aircraft guns and a single bank of five torpedo tubes, giving a less crowded arrangement amidships.
Further developed as Scheme "B-VII" of 10 March 1942, this became the basic DD-692 design.
The original plan is in the 1939-1944 "Spring Styles Book" held by the Naval Historical Center.
