The Adjutant-class auxiliary motor minesweepers were built for the United States Navy throughout the 1950s and 1960s, even as late as 1978.

[1] The Adjutant-class minesweepers were of a wooden construction with brass and stainless steel fittings to reduce magnetic attraction.

[2] Half of the US ships used four Packard 300 hp (220 kW) diesel engines.

The rest and most of the ships built for use by foreign nations used two General Motors 440 hp (330 kW) 8-268A diesel engines.

However, the name Adjutant was canceled and the ship was transferred to the Portuguese Navy as Ponta Delgada (M 405).
