The Terrebonne Parish-class tank landing ship was a class of tank landing ship of United States Navy and later sold to the Spanish, Hellenic, Peruvian, Venezuelan and Turkish Navy.

Several ships proceed to serve in the Vietnam War.

Washtenaw County was sold for commercial service but was abandoned in 1980 in which she remained afloat at the Columbia River as of 6 December 2021.

The ship has been heavily vandalized and stripped of parts throughout the years but despite that, efforts were still being done to repair and make her into a museum ship.

She is also the only ship converted into a mine sweeper from her class.
