U.S.S. Allen M. Sumner DD-692
Shipyard Plans

The Preliminary Designs
Bureau of Ships' "Spring Styles" Book # 3 (1939-1944)
Termed "Spring Styles" by the Preliminary Design staff (after ladies' fashion catalogs), these drawings were an important part of the development of the design of the Allen M. Sumner class. The "Spring Styles" plans usually represent only some of the options presented to the General Board, with the others existing only in tabular form. They also do not often represent final designs, which were developed in detail following approval of basic characteristics and were frequently changed in the process.

Scheme "B"
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 2150-ton (standard displacement) ship, provides a slightly updated Fletcher (DD-445) class destroyer, retaining its five single 5"/38 gun mounts (although two are semi-open mounts) and ten torpedo tubes. Among 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). Naval Historical Center Photo #: S-511-51-G.

Scheme "B-I"
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). Naval Historical Center Photo #: S-511-51-F.

Scheme "B-II"
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. Naval Historical Center Photo #: S-511-51-E.

Scheme "B-III"
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 2180-ton (standard displacement) ship, provides two twin 5"/38 dual-purpose gun mounts (one forward and one atop the after deck house), four twin 40mm anti-aircraft guns, and two triple torpedo tube mountings. Naval Historical Center Photo #: S-511-51-D.

Scheme "B-IV"
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 2195-ton (standard displacement) ship, provides two twin 5"/38 dual-purpose gun mounts forward, four twin 40mm anti-aircraft guns on the corners of a large after deckhouse, and two triple torpedo tube mountings. Naval Historical Center Photo #: S-511-51-C.

Scheme "B-V"
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 2215-ton (standard displacement) ship, provides two twin 5"/38 dual-purpose gun mounts forward and a single 5"/38 dual-purpose gun mount aft, four twin 40mm anti-aircraft guns on the after deckhouse, and two triple torpedo tube mountings. Naval Historical Center Photo #: S-511-51-B.

Scheme "B-VII"
Preliminary design plan prepared for the General Board near the end of the process leading to the Allen M. Sumner (DD-692) class design.
This 10 March 1942 plan, for a 2270-ton (standard displacement) ship, is a development of Scheme "B-II" of 30 September 1941, and was the basis for the DD-692 class design. It provides three twin 5"/38 dual-purpose gun mounts (two forward, one aft), two twin 40mm anti-aircraft gun mounts, and ten torpedo tubes in two banks of five. Note that the bridge arrangement has been altered from the earlier schemes in the Scheme "B" series. Naval Historical Center Photo #: S-511-51.
