The final destroyer in the Zumwalt class, the future USS Lyndon B. Johnson, has departed Bath Iron Works and is headed to Huntington Ingalls Industries in Mississippi for combat system installation. BIW will now turn its full attention to the Arleigh Burke class, said company president Dirk Lesko.
During a briefing at a Surface Navy Association symposium, the Navy revealed its next-generation DDG(X) warship will rely on integrated electric propulsion and will feature enlarged variants of the AN/SPY-6 radar. The vessels will be initially include 32-cell blocks of the Mk. 41 Vertical Launch System, and could also eventually accept a 12-cell block of larger launchers for hypersonic missiles.
A new division within the US Navy's Naval Surface Warfare Center will focus on advancing microwave energy weapons that can attack electronics aboard drones, missiles and small boats. High-power microwave directed-energy weapons offer "a range of effects... from basically jamming a device to physically destroying electrical systems," according to Naval Sea Systems Command.
Testing and operation of combat systems is the next step for the Navy's first Flight III Arleigh Burke-class guided-missile destroyer after achievement of Aegis Light Off. "Achieving ALO is a significant accomplishment," says Program Executive Office Ships, DDG 51 class program manager Capt. Seth Miller, with the new ship "bringing game-changing technology to the fleet."
BAE Systems will perform maintenance and modernization work on the destroyer USS Mitscher under a docking selected restricted availability program. Updates will include the ship's Aegis combat system and command and control equipment.
Researchers paired a mean value first principle parametric engine model with a ship propulsion system model to reveal the importance of considering dynamic engine behavior in the design of propulsion systems for two-stroke engines. The modeling concludes that an engine may be thermally overloaded during acceleration, while deceleration could cause a compressor surge even if the engine power trajectory falls within the static engine power envelope.
Huntington Ingalls Industries says the future USS Fort Lauderdale completed Bravo trials at the end of 2021, and the company expects to deliver the San Antonio-class amphibious transport dock in the first half of 2022. Ingalls is also in the process of building five destroyers, including the future Lenah Sutcliffe Higbee, which is will be a Flight IIA and is expected to be delivered this year.
Unmanned surface vessels tested last fall hold the potential to give the Navy a much more comprehensive picture of strategic areas without putting sailors at risk. One such vessel, the Saildrone Explorer, uses sun and wind power to cover great distances bearing a wide array of sensors and cameras to gauge weather and water conditions and single out targets using machine learning.
