After local patrol operations off the Mugai channel, "Vigilance" performed local escort missions between Ulithi and Kossol Roads and from Kossol Roads to Seeadler Harbor, at Manus, in the Admiralties. For the latter part of February, the minesweeper served as submarine listening watch and harbor entrance patrol vessel at Kossol before she returned to Ulithi.
