looking for high speed sealift capablity...the ferries are the answer...
The success of high speed catamaran technology had caught the eyes of the world only superpower to meet military logistic demands for transporting troops and equipments to the theater of operations in the last 10 years.
Civllian high speed ferries and catamaran were leased and chartered to the military and knowned as HSV (High Speed Vessel) to meet logistic demands and at the same time to evaluates its effectiveness and capabilities.

WestPac Express is a civillian high speed ferry built by Austal Limited, an Australian company with shipbuilding expertise were focused on high speed ferries and catamaran technology. The effectiveness of WestPac Express in her had convinced USN with agreement to use Austal Limited high speed craft design for the Joint High Speed Vessel programme.
her cargoes includes armoured personnel carrier...
WestPac Express was chartered by the Third Marine Expeditionary Force (III MEF) in 2001 for the rapid deployment of Marine battalions and equipment in the Western Pacific for training exercises.

HSV-X1 Joint Venture
she was a ferry called devil cat before being conscripted as hsv-x1....
The Joint Venture is formerly a civillian high speed catamaran car/passenger ferry built by Incat of Tasmania before being intially chartered to USN and then to the US Army for experimental, evaluation and test programme.
Her induction into military service were due to the effectiveness and flexibility of WestPac Express in conducting military transport operations while at the same had proved to be cost and logistically effective in bringing in the troop to operation theater compared to airlift operations.

stern ramp..similar to hsv-x1 and westpac express...to accomodate cargo loading and offloading
HSV-2 also serve as modular shipbuiling design platform where it had the capability to be refitted to support any mission without requiring long shipyard periods.The vessel were also flexible, having the ability to transport military vehicles and troops in a number of deployments including disaster relief and humanitarian operations.
45 knots and 3500nm...loaded with full gear troops and vehicles
