Patrol activities interspersed with minesweeping training absorbed her time until mid-summer when she sailed to the western Pacific Ocean.

Operations commenced at Nagoya 18 October, continued at Kobe in December, and this craft was still partially engaged with this task at the outbreak of the Korean War in 1950.

Previously named and designated Osprey (AMS-28), 17 February 1947, this wooden-hulled ship now sailed directly to help confront this latest communist advance.

15 September her sweeps prepared a firing base anchorage for the big guns of the battleship USS Missouri (BB-63) at the masterful Inchon landings.

Upon return, her continuing aggressive spirit in seeking out and firing on enemy targets ashore and record breaking performance in mine destruction earned medals and promotions for members of the ship's company.
