The U.S. Navy's Naval Sea Systems Command has awarded General Dynamics Advanced Information Systems, a business unit of General Dynamics, a $10 million contract modification to continue producing multi-purpose processor systems and total ship monitoring system kits as part of the Acoustic Rapid Commercial Off-The-Shelf Insertion (A-RCI) program for submarines. Work under this contract includes the production of seven processor systems, nine ship monitoring systems and associated spares in support of submarine modernization. The multi-purpose processor system is a combination of hardware and software that enables submarines to process acoustic signals collected by towed and hull arrays, sphere arrays and the ship monitoring system.
