Watch Shadow Stealth Ship!
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.
