Two aviation logistics support ships are assigned to the Military Sealift Command Maritime Prepositioning Program. They carry aviation maintenance equipment in support of U.S. Marine Corps fixed and rotary wing aircraft.
SS Wright and SS Curtiss are outfitted with both a stern ramp and side ports. Their roll-on/roll-off deck runs the complete length of the ship. When outfitted with mobile facilities, the ships can service aircraft while anchored offshore.
The mission of the rescue and salvage ships is four-fold: to debeach stranded vessels, heavy lift capability from ocean depths, towing of other vessels, and manned diving operations. For rescue missions, these ships are equipped with fire monitors forward and amidships which can deliver either firefighting foam or sea water. The salvage holds of these ships are outfitted with portable equipment to provide assistance to other vessels in dewatering, patching, supply of electrical power and other essential service required to return a disabled ship to an operating condition. The U.S. Navy has responsibility for salvaging U.S. government-owned ships and, when it is in the best interests of the United States, privately-owned vessels as well. The rugged construction of these steel-hulled ships, combined with speed and endurance, make these rescue and salvage ships well-suited for rescue/salvage operations of Navy and commercial shipping throughout the world. The versatility of this class of ship adds immeasurably to the capabilities of the U.S. Navy with regard to rendering assistance to those in peril on the high seas.
