The US Navy now has a 135-foot unmanned ship with a autonomous trimaran design. The 142-ton vessel can carry a large volume of diesel. It ran non-stop from San Diego during recent Western Pacific drills.
The same exercises tested a stealth bomber firing a Long Range Anti-Ship Missile. Drills also used a SINKEX event to sink the old USS Juneau ship. Tests checked new drone tech and long-range attack plans for the fleet.
