AAG is a new system developed for the Navy’s future aircraft carriers and is installed on board USS Gerald R. Ford (CVN 78); the system will also be installed on the future USS John F. Kennedy (CVN 79) and the future USS Enterprise (CVN 80). AAG is a modular, integrated system consisting of energy absorbers, power conditioning equipment and digital controls, designed as the follow-on to the Mark-7 (Mk-7) arresting gear. The Navy is currently utilizing the Mk-7 Mod 3 and Mk-7 Mod 4 designs on all Nimitz-class aircraft carriers.

The AAG architecture, Health Monitoring Assessment and Prognostics technology, and digital control system provides built-in test and diagnosis, resulting in the system requiring less maintenance and manpower to operate than the Mk-7. This change in architecture is designed to provide higher reliability and safety margins, while allowing Sailors to focus on other areas of need. The system is also designed to allow potential arrestm

The CSM is an advanced hydraulic system that uses up to 800 tons of pressure to swage a terminal onto an aircraft carrier purchase cable. This terminal connects to the cross deck pendant that stretches across the flight deck which engages the arresting hook of an awaiting aircraft allowing for a smooth, controlled arrestment.

EMALS is the Navy’s newest complete carrier-based launch system designed for USS Gerald R. Ford (CVN 78) and future Ford-class carriers. The launching system is designed to expand the operational capability of Ford-class carriers, providing the Navy with capability for launching all current and future carrier air wing platforms – lightweight unmanned to heavy strike fighters. The mission and function of EMALS remains the same as the traditional steam catapult; however, it employs entirely different technologies. EMALS uses stored kinetic energy and solid-state electrical power conversion. This technology permits a high degree of computer control, monitoring and automation.
