LHX

LHX amphibious assault ships are a conceptual next-generation assault ship intended to replace the Tarawas. The Navy's current plan is to conduct a service life extension program (SLEP) overhaul on the Tarawa class amphibious assault ships when they reach the 35 year point in their operating life. The SLEP would provide another 15 years of life at a cost of nearly $1.0 billion per SLEP. The SLEP would extend the machinery operating life and provide communications upgrades. However, stability would remain a main concern and the LHA has limited capabilities to support 21st century littoral warfare systems such as the landing craft air cushion (LCAC) and MV-22 Osprey tilt-rotor aircraft.

In the event the Tarawa SLEP is not funded, and if possible further units of the LHA-1 Wasp class are not authorized, the first of the LHX class is planned for authorization 2005 with commissioning in 2011, with at least five units to be constructed. The design would probably be based on the Wasp design, apart from the use of a dry deck for hovercraft instead of a docking well.
