Crater-class cargo ship is a category of EC2-S-C1 type liberty ship freighters constructed by the United States Maritime Commission for use by the U.S. Navy during World War II.[1] The designation 'EC2-S-C1' was composed of 'EC' (for Emergency Cargo), '2' (for a ship between 400 and 450 feet (120 and 140 m) long (Load Waterline Length)), 'S' (for steam engines), and 'C1' for a Type C1 ship.

The class was named for the lead ship of its type, USS Crater (AK-70). Its 62 hulls was the largest among U.S. Navy cargo ship classes.

The ships were propelled by a reciprocating steam engine using a single screw with a power of 1,950 hp (1,454 kW) shaft.
