The Fleet-class unmanned surface vessel is an unmanned surface vessel designed for the United States Navy to be deployed from and s and intended to conduct mine and anti-submarine warfare missions. four units of the class had been built; the first was delivered to the U.S. Navy in 2008. ==Design and development== Developed by AAI Corporation, General Dynamics Robotic Systems, and Maritime Applied Physics,〔(【引用サイトリンク】title=Fleet-Class Common Unmanned Surface Vessel )〕 the Fleet class Unmanned Surface Vessel (USV) is a small, semi-planing hull craft that is intended to operate in an optionally manned configuration to conduct anti-submarine warfare, special warfare, mine warfare and electronic warfare missions from littoral combat ships of the ''Freedom'' and ''Independence'' classes, being constructed using modular design to allow for rapid changes of mission through replacement of modules.〔 in length and displacing 7.7 tons, the Fleet class is capable of speeds of over and can carry up to of equipment.〔 The Fleet class is designed to operate for up to 48 hours without interruption. Designed to match the weight and handling limits of a conventional rigid-hulled inflatable boat, the hull of the Fleet class USV is designed for good seakeeping in most sea states, and the vessels are equipped with advanced controls for autonomous navigation and operation.〔 They are also designed to be converted to manned operation through the replacement of mission modules within a 24 hour period.〔 〕 As part of the LCS Mine Countermeasure (MCM) mission package, the boats will act as the Unmanned Influence Sweep System (UISS), where they will tow a countermeasure system that emits acoustic and magnetic signals to trigger and detonate influence mines at a safe distance. It is also capable of carrying other counter-mine payloads, including a side scan sonar and minehunting and sweeping unmanned underwater vehicles.〔(LCS to get unmanned mine-sweeping boats, drones ) - Defense-Update.com, 9 October 2014〕 The vessels of the Fleet class are the first unmanned vessels to be numbered as ships of the United States Navy.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fleet-class unmanned surface vessel」の詳細全文を読む スポンサード リンク
