New Hampshire company creates first super-cavitating ship. The company’s aim is to interest the US Navy in a high-speed, long-range ship — the water-borne equivalent of an attack helicopter — that could intercept swarms of missile-equipped, small attack boats before they come in range of Navy warships. JMS claims the Ghost has the same maximum speed as the Mark V special-operations boat used by Navy SEALs, but a 50% higher burst speed, twice the range and greater stability in high sea states.

You may have seen a story last week about a company claiming to have developed “the first supercavitating ship“. Ships are not my thing, but I thought I would ask for more information and it arrived this morning (a paper press kit, via FedEx – which made me feel quite nostalgic).

Technical details are sparse, but here is what can be gleaned. The Ghost is a prototype
small waterplane area twin hull (SWATH) ship designed by Portsmouth, N.H.-based Juliet Marine Systems (JMS) and built with the company founders’ own money.The company’s aim is to interest the US Navy in a high-speed, long-range ship — the water-borne equivalent of an attack helicopter — that could intercept swarms of missile-equipped, small attack boats before they come in range of Navy warships.

Supercavitation — creating a bubble of air around a body in the water — can reduce hull friction drag by up to 900%, says JMS, increasing speed and reducing fuel consumption. A key to the Ghost design, the company says, is the ability to generate enough gas to create a boundary layer around the propulsion pods without taking power away from the propulsion system.

JMS claims the Ghost has the same maximum speed at the Mark V special-operations boat used by Navy SEALs, but a 50% higher burst speed, twice the range and greater stability in high sea states. The prototype, which is stealth in shape only, is sized to accommodate a SEAL squad, and JMS says a follow-on design would be air-transportable by C-17.

    Why don’t we try to discover more ways to feed the hungery and to shelter the homless instead of making new and improved weaponds that are really not needed. Lets put forth our cullective efforts into peace and prosperity for every living soul on Earth. Now that would be truly an achievement.
