LHX 未來兩棲攻擊艦計劃


原文:

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.

美海軍將建造新一代兩棲攻擊艦



美國海軍與諾斯諾普.格魯曼公司簽約，將耗資24億美元，建造新一代兩棲攻擊艦。

按照這份建造合約，將在2012到2013年之前完成第一艘兩棲攻擊艦的建造。未來十年內，美國海軍計劃裝備四艘這種兩棲攻擊艦。

這種兩棲攻擊艦的排水量達五萬噸，與中型航空母艦相當，最高航速21到22節。未來將作為遠洋艦隊的旗艦。上面可搭載登陸艇、短距垂直起降戰鬥機、和各種型號的直升機。


※ 將針對兩棲攻擊艦所使用的氣墊登陸艇(LCAC)，進行使用期限擴展計劃(SLEP)，擴展LCAC的使用期限至30年。

※ 可能會從現有的 Tarawas 級 兩棲攻擊艦進行 未來兩棲攻擊艦(LHX)改裝計劃

※ 趨時將會搭載MV-22傾斜旋翼機

※ LHX兩棲攻擊艦的概念是來自於下一個世紀的未來兩棲攻擊艦，並用來取代 Tarawas 級 兩棲攻擊艦。
