Advanced Arresting Gear (AAG)

The Advanced Arresting Gear (AAG) program designed, developed, tested and fielded an aircraft arrestment system to replace the legacy Mark 7 arresting gear. AAG systems are being installed on all new construction aircraft carriers. AAG will provides the U.S. Navy with improved operational capability, while reducing operating and support costs. The AAG system will recover all existing and projected carrier based tail hook-equipped air vehicles well into the 21st century. The AAG program will undergo future system improvements to address safety, obsolescence, reliability, and cyber security to include but not limited to AAG Software Stability, AAG Depot Planning, AAG Software Support Activity (SSA), Reliability Improvement ECPs, Obsolescence ECPs and FLASH. The Software Stability development efforts will address software deficiencies, stability and reliability issues documented in a System Safety Risk Assessment (SSRA) for AAG software, and in a separate investigative report by a NAVAIR Independent Review Team (IRT). Development efforts will mitigate specific findings related to non-deterministic behavior and latency of the software that contribute to the SSRA Hazard rating (1D-Serious). Per IRT report recommendations, these efforts will address findings via software modernization and re-architecture, with new software adhering to improved Level or Rigor (LOR) standards and processes. Development efforts include enhancing the AAG software development laboratory. Completion of AAG Depot Planning includes analysis of test bench and depot repair Support Equipment, final updates to logistics product information and maintenance task analysis, and develop Overhaul work instruction, repair procedures, and overhaul intervals. Previous Depot Planning efforts provided initial analysis and completion of Functional Requirements document (FRD). Depot Planning is approximately 85% complete, and does not have to be 100% complete to begin Depot Standup procurements. AAG SSA funding provides development and execution of a high-level hybrid SSA planning document to ensure software test activities and procedures are implemented for AAG. Reliability improvements will be accomplished with the development of ECPs addressing AAG Production Impacts, including but not limited to ECP-0120 Charging Power Supply, and pECP-027 AAG Water Twister Drain & Fill Kit.

Congressional Add: To maintain a decisive warfighting advantage, this Model Based Systems Engineering (MBSE) initiative will modernize requirements management for the EMALS and AAG systems. This critical effort fosters a transition from an obsolete, unsupported MBSE tool - which presents inefficiencies - to a modern, industry-standard platform with no licensing costs. This migration to a common Navy tool will unlock enhanced traceability, streamlined test verification, and seamless interoperability, directly enabling agile acquisition, responsive software support and continuous fleet improvements. Utilizing the most up to date MBSE tool will enable the EMALS and AAG programs to create robust digital models to design, visualize, document, and manage requirements in a streamlined and cost-effective manner.
