USS Reaper (MSO-467) was an Agile-class minesweeper acquired by the U.S. Navy for the task of removing mines that had been placed in the water to prevent the safe passage of ships.

Sailing for the western Pacific 21 September 1966, she participated in "Operation Market Time" patrol duty off Vietnam during November and December, and in February and March 1967, before reaching Long Beach 27 July.

Deployed to the western Pacific again in April 1968, she patrolled off Vietnam and visited Chinhae, Korea; and Sattahip, Thailand, arriving Long Beach 3 December.

In February, Reaper provided covering fire for her boarding team sent to check out a grounded and abandoned small coastal freighter.

This deployment also saw the untimely death, as the result of a non-combat ship-board accident, of SF2 Lester Riley Jr. Reaper remained active with the U.S.
