Assault is one of the roles of this transport vessel. It has modular weapon systems to match the mission. Very versatile!
It is intended as a small assault transport with a variety of capabilities depending on the mission module installed. The ship is a trimaran design capable of over 40 knots (74 km/h; 46 mph), and was delivered to the US Navy at the end of 2009.
