Bureau of Ships' "Spring Styles" Book # 1 (1911-1925) -- (Naval History and Heritage Command Lot # S-584) --
Patrol and Mine Warfare Vessel Preliminary Design Drawings

Fourteen designs for gunboats and patrol vessels and one design for a minesweeper are included in the total of 211 drawings in the 1911-1925 "Spring Styles" Book. The gunboat designs include two designs for classical cruising gunboats, in effect small cruisers, and eight post-World War I designs for a new class of shallow draught gunboats for operations along Chinese rivers. There are four designs for small anti-submarine warfare patrol vessels, developed during World War I in response to the threat from German submarines. Finally, there is one drawing of a seagoing minesweeper that appears to represent the design selected for construction of the numerous Lapwing (or so-called "Bird" class) vessels of 1917.

This page features those 1911-1925 Bureau of Ships "Spring Styles" plans that concern patrol and mine warfare vessels.

    The Patrol Vessel drawings included in this album are:

    --One proposed design for a gunboat, not selected for construction:

  • S-584-092: Preliminary Design Plan for a Gunboat - November 1915. Preliminary Design No.154 for a 1,575 ton ship with a main battery of three 4-inch guns and a maximum speed of 12 knots. No ship was built to this specific design, although Tulsa (Gunboat # 22) was built to a modified version.

    --One proposed design for the Gunboat Tulsa:

  • S-584-123: Preliminary Design Plan for Gunboat # 22 - November 30, 1917. Preliminary Design No.187 for a 2,100 ton ship with a main battery of three 5-inch guns and a maximum speed of 16 knots. Tulsa (Gunboat # 22) ultimately was built to a smaller design, similar to that of the previous Asheville (Gunboat # 21) because the design shown here was deemed too costly.

    --Seven proposed designs for River Gunboats for Chinese waters, none of which were selected for construction:

  • S-584-185: River Gunboat Designed to Characteristics for the 1924 Building Program - July 7, 1923. Drawing from Preliminary Design Book No.294 of a 490 ton ship with a main battery of two 3-inch guns and a maximum speed of 16 knots. No ship was built to this design.
  • S-584-186: "Shallow Draft Gunboat - Tunnel Stern Type" - July 1923. Drawing from Preliminary Design Book No.299 of a 380 ton ship with a main battery of two 3-inch guns and a maximum speed of 16 knots. No ship was built to this design.
  • S-584-187: "Shallow Draft Gunboat - Tunnel Stern Type" - July 23, 1923. Drawing from Preliminary Design Book No.300 of a 273 ton ship with a main battery of two 3-inch guns and a maximum speed of 15 knots. No ship was built to this design.
  • S-584-188: "Shallow Draft Gunboat - Open Stern Type" - August 4, 1923. Drawing from Preliminary Design Book No.301 of a 375 ton ship with a main battery of two 3-inch guns and a maximum speed of 15 knots. No ship was built to this design.
  • S-584-189: "River Gunboat - Tunnel Stern" - September 28, 1923. Drawing from Preliminary Design Book No.302 of a 600 ton ship with a main battery of two 3-inch guns and a maximum speed of 14.75 knots. No ship was built to this design.
  • S-584-192: "River Gunboat" - March 22, 1924. Drawing from Preliminary Design Book No.307 of a 385 ton ship with a main battery of two 3-inch guns and a maximum speed of 15 knots. No ship was built to this design.
  • S-584-194: "River Gunboat" - April 26 (1924). Drawing from Preliminary Design Book No.310 of a 380 ton ship with a main battery of two 3-inch guns and a maximum speed of 15 knots. No ship was built to this design.

    --The preliminary design selected as a basis for construction of the Guam, Luzon, and Panay class River Gunboats:

  • S-584-193: "River Gun Boat - Tunnel Stern Type" - September 8, 1924. Drawing from Preliminary Design Book No.307 of a 385 ton ship with a main battery of two 3-inch guns and a maximum speed of 15 knots. Six ships of three classes were built to this concept, modified in detail by the builder.

    --Two proposed designs for the "Eagle" class Submarine Chasers:

  • S-584-121: "200-Ft. Sub Chaser - Turbine Design" - November 22, 1917. Preliminary Design No.186 for a 475 ton ship with a main battery of one 5-inch and one 3-inch gun and a maximum speed of 21 knots. The mass-produced "Eagle Boats" of the World War I-era were built to this steam-powered version of this design.
  • S-584-122: "200-Ft. Sub Chaser - Diesel Design" - November 28, 1917. Preliminary Design No.186b for a 500 ton ship with a main battery of two 4-inch guns and a maximum speed of 19.5 knots. The mass-produced "Eagle Boats" of the World War I-era was built to the steam turbine-powered version of this design.

    --Two proposed designs for a 123-foot Submarine Chaser, not selected for construction:

  • S-584-124: Preliminary Design Plan for a 123-foot Submarine Chaser - December 30, 1917. Preliminary Design No.188 for a 83 ton ship with a main battery of one 6-pounder gun and a maximum speed of 32.6 knots. No ship was built to this design.
  • S-584-125: Undated preliminary Design Plan for a 123-foot Submarine Chaser. Rough sketch drawing of a ship with no characteristics data provided. No ship was built to this design.

    The Mine Warfare Vessel drawing included in this album is:

    --One drawing illustrating the Lapwing class Minesweeper design:

  • S-584-129: "U. S. Seagoing Mine Sweepers" - March 28, 1918. Drawing of a minesweeper with no characteristics data provided. The plan looks identical to the Lapwing (Minesweeper # 1) class of 1917-1919.
