Two US Army Blackhawk helicopters created history recently with the first landings on board a US Army vessel since the Vietnam War. After a break of 30years, the Blackhawks touched down on the deck of US Army vessel HSV-X1 Joint Venture at 10.57 am (Korean time) on Thursday 25 March, 2004. HSV-X1 Joint Venture, built at the Hobart shipyard of Incat Australia, has been on lease to the US military since late 2001. The high speed ship completed a major refit at the Tasmanian Incat yard in late 2003 and is now stationed in Hawaii under the command of US Army Pacific.
