The MPS ships in each squadron have sufficient equipment, supplies and ammunition to support a [[Marine Air-Ground Task Force]] for 30 days. The MPS ships are self-sustaining, with [[Crane (machine)|crane]]s to unload at sea or pierside. MSC [[Chartering (shipping)|chartered]] the first two ship classes in the MPS role (the ''Corporal Louis J. Hauge Jr.'' and ''Sergeant Matej Kocak'' classes) from [[civilian]] [[shipping line]]s and converted them. Later ships were purpose-built.
