A joint support ship (JSS) is a multi-role naval ship capable of launching and supporting "Joint" amphibious operations. Providing sea-lift, underway support and sea-basing/logistics capability for combined army and naval missions. Furthermore to fulfill the multi-role part a flexible modular design allows for configuration of temporary areas for different purposes as missions require. As such it is basically a combination of an amphibious warfare ship and different auxiliary ships like replenishment oiler, transport ship and hospital ship in one.
