Bureau of Ships' "Spring Styles" Book # 1 (1911-1925) -- (Naval Historical Center 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.
