has successfully deployed the first digitally-controlled arrestment system that dramatically upgrades the critical process of "catching" aircraft on carriers. The Advanced Recovery Control (ARC) system was deployed on the USS Ronald Reagan (CVN-76) aircraft carrier and performed its first successful operational arrestment at sea on November 5. ARC is the Navy's first electronic digital control system for aircraft arrestment. Awarded to Northrop Grumman
as the prime contractor, the program includes design, development, first article qualification and production. ARC is a key part of the Navy's plans for extending the service life of carriers and allowing for arrestments of heavier aircraft entering the fleet. NAVAIR plans to retrofit ARC on Nimitz-class carriers and also deploy it at three shore-based training facilities.
ARC is an upgrade to the existing MK 7 arrestment system. It uses a precision digital control system to replace the existing maintenance-intensive system of chains, cams and levers to close the constant run-out valve. ARC uses a computer system with feedback and built-in redundancy to accurately and safely arrest the aircraft on the carrier's deck. The ARC upgrade includes digital controls, software, graphical displays, programmable arrestment profiles, and redundant electronically-controlled actuators that precisely control the arrestment process.
