Advanced Arresting Gear

The electric motor-based Advanced Arresting Gear (AAG) system provides for aircraft deceleration during aircraft carrier recovery operations. AAG allows for arrestment of a broad range of aircraft, reducing manning and maintenance, and provides higher reliability and safety margins. AAG's design uses simple, proven energy-absorbing water turbines coupled to a large induction motor for fine control of the arresting forces.

The AAG system offers significant benefits over current recovery systems, including:

  • Operational capability to recover projected air wing, with renewed service life margins
  • Full compatibility with Nimitz-class and Ford-class carriers
  • Higher availability
  • Self-diagnosis and maintenance alerts
  • Reduced manning and total ownership cost

General Atomics Electromagnetic Systems (GA-EMS) San Diego, California, facility houses an AAG Controls and Software Subscale Lab (SSL) to enable the delivery of fully tested controls, software and operator displays. The SSL represents a full shipboard network and subsystems to:

  • Facilitate integration and full regression testing
  • Provide cost-effective simulation of shipboard conditions to enable troubleshooting
  • Improve the quality of software releases.
