Advanced Arresting Gear

The Advanced Arresting Gear (AAG) program will supply Navy aircraft carriers with an electric motor based system that will replace the current MK 7 hydraulic system for aircraft deceleration during recovery operations. AAG allows arrestment of a broader range of aircraft, reduces manning and maintenance, and provides higher reliability and safety margins. GA's design replaces the mechanical hydraulic ram with rotary engines using simple, proven energy-absorbing water turbines coupled to a large induction motor, providing fine control of the arresting forces.

AAG provides significant benefits over current recovery systems

  • Operational capability to recover projected air wing, with renewed service life margins
  • Full compatibility with CVN 68-class and CVN 78-class carriers
  • Higher availability
  • Self-diagnosis and maintenance alerts
  • Reduced manning and total ownership cost (TOC)

The following timeline shows the history of the AAG program from the contract award to General Atomics in 2003 to the present.

AAG Controls and Software Subscale Lab

EMS built an AAG Controls and Software Subscale Lab (SSL) representing a full shipboard network and subsystems in its San Diego, Calif. facility. The lab enables the delivery of fully tested controls, software and operator displays.

  • Facilitates integration and full regression testing of AAG computer software, hardware and controls
  • Provides cost-effective simulation of shipboard conditions, enabling troubleshooting
  • Improves quality of software releases
