USS Spear (AM-322) was an Auk-class minesweeper acquired by the United States Navy for the dangerous task of removing mines from minefields laid in the water to prevent ships from passing.

The minesweeper conducted training exercises there until 3 May when she was assigned escort duty for convoys carrying troops and supplies to advance bases in the Marshall Islands at Majuro, Eniwetok, and Kwajalein.

On 17 July, the minesweeper was attached to a convoy of LST's and proceeded to a rendezvous point just south of Guam for the impending amphibious assault on that island.

Spear steamed to Guam in June for tender availability and, six weeks later, was back at Okinawa when hostilities with Japan ended.

Following the return of peace, she joined in mine-sweeping operations in the East China Sea; helped to clear the approach to and the mouth of the Yangtze River; swept mines off Chefoo, China; and participated in further sweeping operations off Jinsen, Korea, before returning to Shanghai and joining the Yangtze River Patrol Force.
