Advanced Acoustic Concepts (AAC) is a leading U.S. undersea warfare (USW) systems innovator, delivering advanced sonar detection and classification, torpedo defense, and training and knowledge management solutions. As a wholly owned subsidiary of Thales Defense & Security, Inc., AAC combines American operational excellence with Thales’s global engineering precision, all while operating under a U.S. Department of Defense approved Proxy Agreement to ensure trusted and secure mission delivery.
Leveraging an enterprise-engineering model and open, modular architectures, AAC designs scalable, cost-effective solutions using commercial, license-free hardware and software components. From surface ship combat systems to immersive training environments, AAC’s systems are bult to integrate seamlessly, adapt swiftly, and support warfighters with cutting-edge, mission-focused innovations.
The constantly changing complex global security challenges in the undersea environment require innovative warfare solutions that constantly push the limits of technology. Since AAC’s founding in 1989, AAC has been focused on the design and delivery of technologically advanced systems for the warfighter through execution of “Rapid Capability Insertion (RCI)” programs.
Leveraging commercial-of-the-shelf (COTS) technology enables Naval Platform’s onboard computing power to grow at nearly the same rate as commercial industry facilitating regular updates to signal-processing software to maximize the utilization of the additional computing power. RCI programs provide vast improvements in sensor performance utilization without changing the actual sensor, therefore providing the most advanced sensing capabilities at the most reasonable cost.
100% U.S. Company
TDSI operates in accordance with a Proxy Agreement approved by the U.S. Government, established to mitigate concerns associated with Foreign Ownership, Control, or Influence (FOCI). To mitigate potential FOCI, Thales Defense & Security, Inc., in concert with the DoD’s Defense Counterintelligence and Security Agency (DCSA), has agreed to a comprehensive series of controls and requirements set forth by the Proxy Agreement (the highest-level FOCI mitigation instrument), subject to oversight by the Government Security Committee (GSC) to ensure independent TDSI management. As such, TDSI is approved to work on the full spectrum of U.S. Government classified and unclassified programs without restriction, and is positioned to support strategic partnerships in the development of key technologies for the defense market. Thales’ Proxy Agreement has been active since 1986, initially as Racal Communications, Inc., making it one of the longest-standing proxy agreements in the U.S. National Industrial Security Program (NISP).
