December 30/21: CVN 81 General Atomics won a $69.9 million deal that provides non-recurring engineering and program management services in support of the Electromagnetic Aircraft Launch System (EMALS) and Advanced Arresting Gear (AAG) system for the CVN 81 aircraft carrier, minus energy storage subsystem. The deal provides for the evaluation, production, manufacture, assembly, integration and test of engineering changes to product hardware, software, technical data, and logistics products throughout the configuration management process associated with the EMALS and AAG system for the CVN 81 aircraft carrier, minus the energy storage subsystem. Work will take place in California. Estimated completion will be in December 2023.

EMALS Components (click to view full) As the US Navy continues to build its new CVN-21 Gerald R. Ford Class carriers, few technologies are as important to their success as the next-generation EMALS (Electro-MAgnetic Launch System) catapult. The question is whether that technology will be ready in time, in order to avoid either costly delays to the program – or an even more costly redesign of the first ship of class. Current steam catapult technology is very entertaining when it launches cars more than 100 feet off of a ship, or gives naval fighters the extra boost they need to achieve flight speed within a launch footprint of a few hundred feet. It’s also stressful for the aircraft involved, very maintenance intensive, and not really compatible with modern gas turbine propulsion systems. At present, however, steam is the only option for launching supersonic jet fighters from carrier decks. EMALS aims to leap beyond steam’s limitations, delivering significant efficiency savings, a more survivable system, and improved effectiveness. This free-to-view spotlight article covers the technology, the program, and its progress to date.
