Juliet Marine Systems ‘GHOST’ @ $10 Million: U.S. Navy will boast

Juliet Marine Systems ‘GHOST’

Juliet Marine Systems ‘GHOST’: Mission of Juliet Marine Systems is to deliver class-leading performance to commercial and defense applications through their propriety marine technologies, while continuing to innovate and advance the state-of-the-art in high performance marine systems. And they have proved their honest mission as they have designed, developed, and built this GHOST which is a highly advanced reconfigurable SWATH stealth-capable warship currently under development for the U.S. Navy.

Applications of Juliet Marine Systems ‘GHOST’

According to Juliet Marine Systems, GHOST can be used in special operations for intelligence, surveillance, and reconnaissance tasks. The GHOST is expected to take on deadly military duties when equipped with the right weapons. The future might see the boat capable of attack helicopters and incoming small attack vessels.
Other than military uses, the vessel could also be used for civilian duties, as a high-speed maritime ferry or taxi services, offshore oil rig supply, or even as a pleasure cruise o the waters.

 Juliet Marine Systems ‘GHOST’ How it works?

At the front of each foil is a special propeller system that pulls the craft forward. The propellers are powered by a modified gas turbine—a jet engine—housed in each foil; the air intake and exhaust ports for the engines are in the struts. As the ship moves through the water, the motion of the propellers creates a thin layer of bubbly water vapor that surrounds each foil from front to back, helped along by the presence of “air trap fins” that keep the vapor in contact with the hull (and keep liquid away from the hull). The vapor is what constitutes the supercavitation, so the foils can glide effortlessly through the bubbles.

Design of Juliet Marine Systems ‘GHOST’

Ghost uses a dual-pontoon supercavitating hull, known as the small waterplane-area twin-hull (SWATH), to run at top speed through 10 ft (3.0 m) seas. It is gyro-stabilized, control is provided by 22 underwater control surfaces. Below eight knots, Ghost sits in the water on its centerline 38 ft (12 m)-long module; faster than this, the marine aluminum buoyant hulls lifts the main hull out of the water by two 12 ft (3.7 m)-long struts, achieving full stability and reducing the amount of area resisting the water.

Each strut is attached to a 62 ft (19 m)-long underwater tube that contains the engines. Four propellers are at the front of the tubes, which is more stable and allows for better control at high speeds; the propellers funnel air down through the struts, creating a gas bubble around each tube (the cavitation effect) for reduced drag and smooth motion.

Propulsion on the prototype is provided by two T53-703 turboshaft engines providing 2,000 horsepower, there are plans to later adopt the General Electric T700 turboshaft engine. Since the tubes that contain the engines, fuel, and most computing systems are underwater, this lessens vulnerability because critical systems are protected by the water itself. The aircraft-style cockpit is outfitted with large windshields fashioned from two inch-thick glass; steering is provided via a throttle and joystick arrangement. Ghost has achieved speeds of over 30 knots, and is being tested to 50 knots.

Review of Juliet Marine Systems ‘GHOST’

There are a few things the Ghost does very well: Its clever design makes its radar signature minimal, so most larger ships won’t even pick it up on their radar displays. And since its cockpit sits far above the water, it can literally cut through waves for a smooth ride, reducing the slamming effect that rough water would have on a crew.

Gregory Sancoff, President and CEO of JMS, states, “GHOST is capable of covering both coasts of South Korea with just one fueling. It is especially effective in the West Coast areas of South Korea where stable and fast operations in high waves are desired by the Korean Navy and Korea Coast Guard, and could be used to protect maritime border islands including Yeonpyeongdo, located just 7.5 miles south of the coastline of North Korea. Juliet Marine Systems is open to discuss licensing of drag reduction and control technology to South Korea and co-development of the next generation GHOST.  I believe our patented technology and GHOST will further strengthen South Korea’s military in the near future.”

Sancoff told “You can sit there and drink your coffee going through six-foot swells”. But Ghost’s most cutting-edge feature is its propulsion technology, which has far-reaching implications for navies with access to it.”He put the propellers at the forward end of these two hull forms,” Rear Adm. Jay Cohen (Ret.), the former head of the Office of Naval Research, and now a board member for Juliet, told Business Insider. “It’s like riding on two fins attached to two submarines. But instead of pushing, they are pulling.”
