USS Portent (AM-106) was an Auk-classminesweeper acquired by the United States Navy for the dangerous task of removing mines from minefields laid in the water to prevent ships from passing.
Portent — a metal-hulled minesweeper — was named after the word "portent," something that foreshadows a coming event. In this case, it was an appropriate name since the Portent struck a mine and was sunk not long after her commissioning.
Portent was laid down on 15 November 1941 by the Pennsylvania Shipyards, Inc., Beaumont, Texas, launched on 16 August 1942, sponsored by Mrs. Arthur L. Kline, Jr., and commissioned on 3 April 1943.
