SUPER FAST stealth attack boat for the US military and Navy

Another great idea for the us military and us navy . This fast attack stealth boat will make a difference. GHOST is a super-cavitating surface craft which is able to achieve 900 times less hull friction compared to a conventional watercraft and is developed by US Citizens for the US Navy at no cost to the US government for providing superior protection to US service personnel. The craft was built by Juliet Marine Systems. The secrecy orders on the project were removed on 11 August 2011[1]

Design
The Ghost uses a gyro-stabilized dual-pontoon supercavitating hull to run at top speed through 10-foot seas. Called small waterplane-area twin-hull (SWATH), it is controlled by 22 computer-controlled underwater control surfaces. When at rest or moving slowly, the Ghost sits in the water on its centerline module. At eight knots or faster, the high-grade marine aluminum buoyant hulls lift the vessel and achieve full stability. Propulsion on the prototype is provided by T53-703 turboshaft engines, with the company planning to replace them with the General Electric T700 turboshaft. The Ghost has achieved speeds of over 30 knots, and is being tested to 50 knots. It can perform several different missions including anti-surface warfare (ASuW), anti-submarine warfare (ASW), and mine countermeasures (MCM): ASuW armament consists of the M197 20mm rotary cannon and launch tubes that expel exhaust downward between the struts of the SWATH hulls, concealing and dissipating the thermal signature of the launch for BGM-176B Griffin missiles and Advanced Precision Kill Weapon System rockets, with an electro-optical/infrared (EO/IR) sensor and radar; an ASW version could be equipped with an EO/IR sensor, radar, sonobuoy launch tubes, a dipping sonar, and four aft-firing torpedo tubes; an MCM version could be equipped with a towing boom to lower and raise two towed mine-hunting sonars, such as the Kline 5000 or Raytheon AN/AQS-20A. The current Ghost costs $10 million per copy, is crewed by 3-5 sailors, and can be partially disassembled to fit in a C-17 Globemaster III for transport if needed. It is designed for fleet protection for navies with few blue-water needs but require a small and affordable craft in large numbers for near-shore maritime border patrol and defense missions; it is being offered to international customers including Bahrain, Qatar, Israel, Saudi Arabia, Japan, Taiwan, South Korea, and Singapore. High-level discussions have been held with a foreign nation interested in 25 Ghosts for a potential $300 million sale. Juliet Marine is also offering a scaled-up version of the Ghost to the U.S. Navy as part of their re-evaluation of the Littoral Combat Ship program. Plans are to build a corvette-sized Ghost of 150 ft (46 m) in length or more costing about $50 million per vessel, six times cheaper than the $300 million per-ship cost of a current Freedom-class and Independence-class littoral combat ship. One impediment to the U.S. Navy procuring the Ghost is the desire of senior Navy leaders to have large-hulled oceangoing vessels that can also perform inshore operations rather than smaller craft specialized for inshore missions.[2][3]

Juliet Marine Systems is a maritime technology think tank that is developing innovative solutions for naval and commercial applications. We seek to assure fleet force protection in response to small vessel terrorist attacks against our Navy and coalition ships. There is a clear and present danger of these tactics being used against the U.S. Navy throughout the world and in our home ports. These same innovative technologies, applied to commercial needs, will provide a significant decrease in transit time and increase in energy efficiency, resulting in the savings of thousands of gallons of fuel daily.

Our Navy is in a revolutionary period of change. Historic military tactics combined with modern materials and technology present a formidable fleet protection challenge for our Navy today. One of the greatest threats to our Navy is low tech vessel attacks with conventional explosives, as seen on October 12, 2000, when the USS Cole was attacked, killing 17 sailors and wounding 39 others and in the continued success of pirates. As a maritime systems think tank, Juliet Marine Systems provides offensive, defensive and ISR solutions that are developed in a skunk works operation able to rapidly invent and construct needed technologies and systems for the Navy and armed forces. We have already developed a surface variant of a super cavitating craft and are planning to apply our unique technology in a UUV prototype.

While the GHOST is a surface vessel, the hydrodynamics of the twin submerged buoyant tubular foils are also a test bed for Juliet Marine's next planned prototype, a long duration UUV. The GHOST is a revolutionary proprietary technology vessel platform that will assure force protection through stealth fighter/attack capabilities along with integrated situation awareness.

SUPER FAST US Navy M80 Stiletto Stealth Ship
The United States Navy (USN) is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States.
The M80 Stiletto is a prototype naval ship manufactured by the M Ship Company as an operational experiment for The Pentagon's Office of Force Transformation. It is notable for its Pentamaran hull design and carbon fiber construction, as well as its networked architecture.
The M80 Stiletto is a U.S. Navy vessel designed for combat in littoral waters. It takes the name from the Italian Stiletto, a short knife or dagger.

The 88-foot (27 m) long vessel has a notable hull design, an M-shaped hull that provides a stable yet fast platform for mounting electronic surveillance equipment or weapons, or for conducting special operations. The hull design does not require foils or lifting devices to achieve a smooth ride at high speeds in rough conditions. Its shallow draft means the M80 Stiletto can operate in littoral and riverine environments and potentially allows for beach landings. The faceted design suggests that the vessel has a low radar signature (i.e., stealth) in the frontal aspect and somewhat so from the sides.

The M80 Stiletto is equipped with four Caterpillar, Inc. C32 1232 kW (1652 HP) engines yielding a top speed in excess of 50 knots (90 km/h) and a range of 500 nautical miles (900 km) when fully loaded. It can be outfitted with jet drives for shallow water operations and beaching.

It has a topside flight deck for launching and retrieving UAVs and a rear ramp that can launch and recover an 11-meter rigid-hull inflatable boat (RIB) or Autonomous Underwater Vehicle (AUV).

It weighs 45 tons unloaded, light enough that it can be hoisted onto a cargo ship, while still able to carry up to 20 tons of cargo. The ship is 88.6 feet (27.0 m) in length, with a width of 40 feet (12 m) and a height of 18.5 feet (5.6 m), yet has a draft of only 2.5 feet (0.8 m).

The M80 Stiletto is the largest U.S. naval vessel built using carbon-fiber composite and epoxy building techniques, which yields a very light but strong hull. The prototype M80 Stiletto is expected to be in use in less than one year. Ships are expected to cost between $6 and $10 million.
Historically, ships have evolved to become narrower and deeper to achieve speed and stability. The M Hull however become wider, because its distinctively wide hull captures the vessel's bow wave and redirects the energy under the hull. The Stiletto's double-M hull enables the craft to achieve an unequaled ride in rough seas at high speed, which is critical for the Navy SEALS and other Special Operations Forces, because it reduces the G-forces and related injuries these personnel are subjected to during training and on missions.

The Stiletto is being tested by the United States Navy SEALs and Special Warfare Combat Crewmen, who operate small, fast craft in the rough littoral seas for which the vessel was designed.
In 2006 and 2007, the Stiletto participated in Trident Warrior exercises, as well as a number of other naval exercises. This included three days of mine-clearing experimentation during Exercise Howler in 2006, when the vessel was operated by the Naval Special Clearance Team-1 (NSCT-1) from the Naval Amphibious Base in Coronado.

A key feature of this vessel is that it can set up a network between a special forces team by launching an unmanned aerial vehicle (UAV) that relays information between the team and boat. The Stiletto can also carry surveillance UAVs to provide reconnaissance for the SEAL team, and, using a clustered supercomputer on board, will be able to send real-time images to the team on shore.

The Stiletto was selected by Time magazine as one of the Best Inventions of 2006 and one of two inventions in the Armed Forces category.[1] San Diego-based CONNECT named the M80 Stiletto as the Most Innovative New Product for 2006 in the General Technology category.

In 2008, the Stiletto deployed on a 70 day mission for USSOUTHCOM as part of a joint agency operation that included the Drug Enforcement Administration and U.S. Coast Guard.[2]

In July 2012, the US Navy deployed a Stiletto to retrieve the NASA Inflatable Reentry Vehicle Experiment 3 (IRVE-3) test article[3] with 3 m (9.8 ft) diameter heat shield which splashed down in the Atlantic Ocean off North Carolina after being launched on July 23 by a sounding rocket from NASA's Wallops Flight Facility. The Stiletto is referred to as a maritime demonstration craft operated by the Naval Surface Warfare Center Carderock, Combatant Craft Division, and based at Joint Expeditionary Base Little Creek-Ft Story, Va.[4]
The United States Navy (USN) is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. It is larger than the next 13 largest navies combined in terms of battle fleet tonnage, according to one estimate.[5][6] The U.S. Navy also has the world's largest carrier fleet,
