The EMALS comes in 2 launcher configuration while the AAG will have 3 engines.
As noted by Alert 5, France has secured the Electromagnetic Aircraft Launch System (EMALS) and Advanced Arresting Gear (AAG) for its next aircraft carrier as the US State Department approved the Foreign Military Sale on Dec. 21, 2021.
According to Transmittal No 21-65, the EMALS comes in 2 launcher configurations while the AAG will have 3 engines. The package is worth up to $1.321 billion.
EMALS is the US 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 the capability for launching all current and future carrier air wing platforms – lightweight unmanned to heavy strike fighters. The mission and function of EMALS remain 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.
Benefits
- Increased reliability and efficiency
- More accurate end-speed control and smoother acceleration
- Expanded operational capability with increased sortie rates
- Cost reduction over time due to decreased manning and maintenance requirements
- Ability to launch a broader range of naval aircraft – from lightweight unmanned to heavy strike fighters- with less stress on the ship and aircraft
- Provides necessary higher launch energy capacity
- Substantial improvements in system weight, volume, and maintenance
- EMALS over steam catapults means quieter and cooler work and living spaces for Sailors
- More intuitive maintenance software will reduce troubleshooting times
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 provide built-in tests 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 the potential arrestment of a broader range of aircraft, from the lightest unmanned aerial vehicles to the heaviest manned fighters.
Benefits:
- Employs advanced technologies to provide higher reliability and safety margins
- Requires less maintenance and manpower to operate than the legacy arresting system
- Recovers all current and projected future carrier-based aircraft, from the lightest unmanned aerial vehicles to the heaviest manned fighters
- Allows for increased sortie rates, lower energy consumption, and a decreased gross ship weight
