Matte gray, with the chiseled angles of a Nighthawk stealth aircraft, doesn’t look like a boat. Its 38-foot main hull is designed to travel above the water’s surface, propped up by two narrow struts, both 12 feet long and razor-sharp at the front so they can cut through ocean debris. Underwater, each strut is attached to a 62-foot-long tube that contains a gas turbine engine. Hinges allow the struts to move up and down like wings. While parked, or traveling through shallow waters, they can be extended to the side. In deeper waters, at speeds of eight knots or higher, they can rotate downward to lift the hull into the air, eliminating the jarring impact of waves. |

Not Invented Here.
Probably good for Coast Guard interdiction missions. |

Um,
That isn't stealth. Just sayin. Just those exhausts or vents or whatever are probably pretty reflective. |

It's pointless to spend money on the military when the administration (and by tolerating it the American people) are too cowed or stupid to utilize any of it in an effective, much less efficient, manner. It's the same as Ray Charles buying a Ferrari collection. Lots of money spent on maintenance intensive depreciating assets with no purpose.

None of that technology will ever be used. Everything we do now we uses FA-18's to drop bombs.

For the US, looks useful for amphib groups, SEAL deployment, and the flexible power projection offered ability to have it combat ready in any conflict zone world wide in 24 hours by aircraft (fewer are required).
I guess it would be nice for drug interdiction in the Gulf too. We used to have the Pegasus class hydrofoil that did this. View Quote Except this ship is twice as fast as a Pegasus with the same range and only a 3 man crew and a massively more efficient propulsion system, not to mention the low observability. Quoted:
We have stealth ships. They're called submarines. View Quote It should be the fastest thing on the water and invincible to submarines as it can outrun any torpedo except a Shkval. Ghost uses supercavitating propulsion to get the speed/efficiency. It might be superior to a helicopter for ASW for amphib group with similar speeds to a helicopter and much longer endurance. Until they get the V-22 outfitted for ASW. |

The logistics alone to keep the engines running negate its usefulness, never mind trying to carry a squad or plt with full kit. |

This ship looks like more of a replacement for the Mark V SOC, more air mobile than a Mark V, longer range, faster, more firepower, lower observability.
It would also fill the role the Pegasus had, albeit with much weaker anti-surface capability, although with a modular payload, I assume you could put good missiles, sensors and datalinks on it. No 76mm gun though. The Cyclone is a pig but it has mass and endurance that neither Ghost, Mark V, nor Pegasus had. |

Yeah, but what is it going to do? If you want to sink a ship by stealth you use a sub. If you want to carry stuff you usually can't do it on a small little dingy like that. |

So according to the article, its current top speed is 29 knots, and they think it might do 50 knots.
|
|
The article I read said it will do 80kn and possibly 100kn. Watch the video it is clearly going MUCH faster than 28kn.

Quoted:
"We’re basically riding on two supercavitating torpedoes. And we’ve put a boat on top of it,” Sancoff says. <a href="http://www.xconomy.com/boston/2012/06/21/juliet-marines-ghost-ship-emerges-from-stealth-startup-gears-up-for-war/attachment/patent_diagram/" target="_blank">http://www.xconomy.com/wordpress/wp-content/images/2012/06/patent_diagram-300x210.png</a>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. View Quote I bet Hydrophones eat that shit up. |

Once they got repurposed they became useful-ish nothing the CG can't do. As far as the initial intent for them they fell well short of what had been promised, cramped is an understatement. |
