''Sea Fighter'' (FSF-1) is an experimental littoral combat ship under development (2005-2008) by the United States Navy. Its hull is of a small-waterplane-area twin-hull (SWATH) design, provides exceptional stability, even on rough seas. The ship can operate in both blue and littoral waters. For power, it can use either its dual gas turbine engines for speed or its dual diesel engines for efficient cruising. It can be easily reconfigured through the use of interchangeable mission modules. Helicopters can land and launch on its deck. Smaller water craft can be carried and launched from its stern. The vessel is being developed under the program title Littoral Surface Craft-Experimental (LSC(X)) with a hull type designation Fast Sea Frame. The first vessel has been assigned the hull classification symbol FSF 1〔 and also has been referred to as the X-Craft. The vessel was designed by British company BMT Nigel Gee Ltd (formerly BMT Nigel Gee and Associates Ltd) who continue with a role in the development of the vessel.〔 BMT Technical paper on the project. http://media.bmt.org/bmt_media/resources/29/Paper49-TheX-Crafta73mExperimentalPlatformfortheUSNavy.pdf 〕〔 Design specifications, plans and images. http://media.bmt.org/bmt_media/resources/29/NG427-SeaFighterFSF1.pdf〕 == Description == ''Sea Fighter''s hull is a small-waterplane-area twin hull (SWATH) design, constructed out of aluminum. With twin gas turbine engines, quad water jets, and a streamlined hulls, ''Sea Fighter'' is capable of speeds of and greater. It is designed to be a sea frame that can carry interchangeable mission modules resembling shipping containers. These modules allow it to be easily reconfigured to meet a variety of mission requirements, including mine warfare, anti-submarine operations, amphibious assault support, surface warfare, transport and logistical missions, cruise missile launch, and special forces interdiction operations. The mission modules are easily loaded and stored on ''Sea Fighter''’s inner deck. Yulista just won the contract to manage the vessel through September of 2020. The vessel has the capability of launching small craft up to 11m in length from the stern, including assault craft and submersibles by means of a custom dual-purpose ramp that also enables RORO operations for HMMWV and other vehicles. The vessel also has a twin-pad helicopter deck capable of operating aircraft up to the size of an H-60 type, including unmanned aerial vehicles, and landing helicopters while traveling at speeds of up to . A special deck lighting system has been developed for ''Sea Fighter'' using low intensity green lighting around the vessel's edges and helipads. This lighting is particularly effective when using night vision goggles, making landings on the vessel easier than on conventional warships, even at the higher speeds in which ''Sea Fighter'' operates. The basic design has a displacement of 1,100 tons while measuring 79.9 m (73 m at waterline) long and 22 m broad. Power is provided by a CODOG arrangement comprising two MTU 595 diesel engines and two LM2500 gas turbines. Diesel power is used for cruising while the turbines provide high power output for high-speed operation. The two gas turbines power the vessel's quad water jets, drawing water from the bottom stern of each hull and powering it through large water turbines, which are responsible for the vessel's remarkable speed. Each water jet has thrust vectoring and thrust reversers making it possible to move sideways while docking, or even traveling in reverse. Thrust vectoring also makes it possible for ''Sea Fighter'' to make dramatic evasive maneuvers while traveling at high speed. This would prevent the craft from being forced to shore or into the path of enemy vessels. ''Sea Fighter''s forward superstructure consists of a bridge on the lower deck, and a flight operations station on top. The bridge is relatively small, and generally manned by a crew of three. The bridge control stations incorporate glass displays using the latest in navigational aids to assist ''Sea Fighter'' in patrolling coastal areas while operating at high speed. Above the bridge is a small flight operations station with room for only one operator. This glass enclosed station provides an excellent view of the entire flight deck, and allows the operator to coordinate the approach and landing of helicopters, and loading of the vessel's mission containers, as well as providing visual aid for navigation. The ship has a computer system to control its systems and for navigation. Steering and throttle control are done by wire rather than mechanical linkage. The first vessel of the type (FSF 1) was constructed at the Nichols Bros. Boat Builders shipyard at Freeland, Washington, under contract to Titan Corporation, a subsidiary of L-3 Communications.〔 Nichols Shipyard was selected because of their previous experience in the construction of aluminum-hulled high speed ferries. 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「Sea Fighter (FSF-1)」の詳細全文を読む スポンサード リンク
