DARPA is moving into Phase 2 of its No Manning Required Ship (NOMARS) program. It aims to build and demonstrate an innovative new Medium Unmanned Surface Vessel (MUSV) that can go to sea and perform missions with unprecedented reliability and availability. important payload.
DARPA Selects Serco Inc. for Novel Design Named Defiant
DARPA press release
The agency chose Serco Inc.’s design to move forward at the end of Phase 1.
normals We take a blank slate approach to ship design and hold firmly to the requirement that ships be unmanned while at sea, including during ongoing replenishment (UNREP) events. By eliminating constraints and requirements, NOMARS has opened the design space to new ship configurations and capabilities unthinkable for manned ships.
NOMARS is also pushing the limits of vessel reliability. With no maintenance crew on board, NOMARS will require new approaches to power generation, propulsion, machinery line-up and control schemes to ensure continuous operation throughout long-term missions in all weather, temperature and sea conditions. I needed to ensure functionality.
“NOMARS plans to demonstrate the next generation of fully unmanned ships that will enable the operation of completely new concepts. Gregory AvikolaDARPA Program Manager tactical technology room“We enable a way to deploy and maintain a very large fleet of unmanned surface vessels that can act as partners around the world for the U.S. Navy’s large manned combatant force.”
In Phase 1, Serco will launch a new Design Space Exploration (DSX ) developed a toolset. Serco used her DSX tools to create a series of ship designs ranging from 170 to 270 metric tons, which he retrofitted into one of her ships for preliminary design review. rebelliousIn Phase 2, Serco finalizes the ship’s design, builds the ship and undergoes a series of rigorous testing activities before putting it to sea for a three-month demonstration event. Serco owns Beier Integrated Systems LLC, Caterpillar, DRS Naval Power Systems Inc., ICE FLOE LLC (dba Nichols Brothers Boat Builders), Metron Inc., Serco Inc. (div Maritime Engineering Operations), Submergence Group LLC, and Thrustmaster of Project Texas Company.
rebellious It will be the first of its kind. At 210 tonnes, her MUSV-class vessels aim to maximize performance, reliability and maintenance efficiency while carrying considerable payloads in a tactically useful range. The goal is to achieve ultra-reliability goals by integrating distributed hybrid power generation, pod propulsion, and high-capacity batteries. A key philosophy of NOMARS is “Graceful Degradation”. This allows individual pieces of equipment to fail over time by having enough system-level redundancy to meet full system requirements at speeds of at least 15 knots after one year at sea. increase. Key system components in the design chosen are modular, allowing repairs to be performed using equipment commonly found in yacht yards around the world. This maintenance philosophy supports rapid turnarounds and allows the vessel to perform missions at sea for the majority of its life.
