USS Independence LCS-2

It is intended as a small assault transport that can take on various capabilities with the installation mission modules. The ship is a trimaran design that can make more than 40 knots (74 km/h; 46 mph), and was delivered to the Navy at the end 2009.
The design for Independence (LCS 2) is based on a high-speed trimaran (Benchijigua Express) hull built by Austal (Henderson, Australia). The 418-foot (127-meter) surface combatant design requires a crew 40 sailors. Although the trimaran hull increases the total surface area, it is still able to reach sustainable speeds about 50 knots (60 mph; 90 km/h) with a range 10,000 nautical miles (19,000 km).
With 11,000 cubic meters payload volume, it was designed with enough payload and volume to carry out one mission with a separate mission module in reserve, allowing the ship to do multiple missions without having to be refitted. The flight deck, 1,030 m2 (11,100 sq ft), can support the operation two SH-60 Seahawk helicopters, multiple UAVs, or one CH-53 Sea Stallion-class helicopter. The trimaran hull will allow flight operations up to sea state 5.
