U.S. Navy approves Rolls-Royce engines for uncrewed surface vessels up to 30 days at sea
The U.S. Navy has approved Rolls-Royce marine engines for uncrewed surface vessels that can operate for up to 30 days without crew, the outlet said. The certification covers the MTU Series 4000 and Series 2000 engines and reflects requirements under the U.S. National Defense Authorization Act. The engines can be installed on long-duration uncrewed craft designed to run for extended periods without routine maintenance, though actual endurance will vary by design and operating conditions.
