The Lapwing-class minesweeper, often called the Bird class, was an early "AM-type" oceangoing minesweeper of the United States Navy. Seven ships of the class were commissioned during World War I, and served well into the 1950s. A number were refitted to serve as ocean-going tugs, salvage vessels, seaplane tenders, or submarine rescue ships.
The propulsion system consisted of 2 Babcock & Wilcox 200psi boilers and a 1,400shp Harlan and Hollingsworth triple expansion reciprocating steam engine.
