An Andromeda class attack cargo ship was an amphibious cargo ship built by Federal Shipbuilding & Drydock Co. in Kearny, New Jersey and Moore Dry Dock Co., in Oakland, California; during World War II. Like all attack cargo ships, they were designed to carry combat loaded military cargo and landing craft, and to use the latter to land weapons, supplies, and troops on enemy shores during amphibious operations. The complement varied as well, but the Dictionary of American Naval Fighting Ships figures sometimes seem to confuse ship's company with embarked troops in determining a ship's complement.
