These new minesweepers were smaller and built primarily of wood , with bronze and stainless (non-magnetic) steel fittings to minimize their magnetic signature. All of the 1950 era MSOs had UQS-1 mine-locating sonar.  MSOs were capable of sweeping for moored, bottom contact, magnetic and acoustic mines.
