The US Navy now has a 135-foot unmanned ship with a autonomous trimaran design. The 142-ton vessel can carry 14,000 gallons of diesel. It ran continuously from San Diego during recent Western Pacific drills.
The same exercises tested a stealth bomber firing a advanced naval Missile. Drills also used a target practice event to sink the old USS Juneau ship. Tests checked new drone tech and strategic attack plans for the fleet.
