One of the contenders for the USN's MASC program (Modular Autonomous Surface Craft)
Zero crew. 90 sea days. 11,500 trans-Pacific miles. 29 mph.
190 ft by 30 ft. 850 tons displacement. 165 tons cargo. 4x 40 foot ISO containers.
10-20 ships per year from one robotic production line.
A new class of ship may be entering service for the U.S. Navy soon, and it has some distinct differences from previous ships. Here's what we know.

"Blue Water developed the Liberty Class using the Damen Stan Patrol 6009 hull as its template, featuring an axe bow design. This improves stability in rough seas, which is vital for autonomous operation. Each vessel measures 190 feet in length with a beam of 30 feet, displacing around 850 tons. They have a maximum speed of 29 mph and can sail for 11,500 miles while carrying four standard 40-foot cargo containers. These allow a Liberty Class ship to carry up to 165 tons.
"The ships are designed without any need for heating, ventilation, or air conditioning, as they aren't meant to house personnel. Without crewed spaces, the internal layout requires far less installation of unneeded devices. Without a single human onboard, a Liberty Class ship can operate for 90 days."

"Because Blue Water licensed the Stan Patrol 6009 hull, it can be produced far faster than it would through standard naval procurement and production processes. This removes the need for further hull development while allowing for easily installable off-the-shelf components. Blue Water is constructing its Liberty Class ships at Conrad Shipyard in Morgan City, Louisiana, where the production line employs robotic assembly systems and can build these ships at a rate of between 10 and 20 per year. Construction of the first vessel in the product line began in March 2026, and if it works as advertised, it's likely that we'll soon see Liberty Class vessels operating around the world."

I found this factoid fascinating
"The Liberty Ship that holds the record for being the fastest from the laying of its keel to completion is the SS Robert E. Peary. From start to finish, the Perry took exactly 4 days, 15 hours, and 29 minutes to construct."

Kaiser at Vancouver, WA built 50 11,000 tonne Escort Carriers in a year (July 1943 to July 1944) by putting a flat deck on a standard cargo hull (Type C3)
5 were sunk between Novenber 1943 and February 1945.
