RTI Product Development: USW Software
The Undersea Warfare (USW) product line delivers to the U.S. Navy a wide spectrum of systems that provide anti-submarine warfare (ASW) capability, marine mammal detection (MMDM) capability, and defense against torpedo attack (TDCL). AAC’s USW products have been deployed on a wide variety of current U.S. Navy surface and sub-surface platforms such as DDGs, CGs, CVNs and SSNs, and will be used on future platforms such as DDG-1000 and LCS.
  • MMDM:
    • Marine Mammal Detection and Mitigation (MMDM) is a program developed to reduce the risk to marine mammals during sonar operations associated with naval exercises and commercial shipping. This unique technology was developed in partnership with Analysis Design & Diagnostics, Inc. (AD&D). Combining AD&D’s innovative detection and classification of marine mammal vocalizations with AAC’s sensor and signal processing, the team has provided the U.S. Navy with an effective automated detection and classification system. This system is being used by the U.S. Navy on Improved Performance Sonar (IPS) surface ships.

  • TDCL:
    • The Torpedo Detection Classification and Localization (TDCL) program employs both passive and active sonar signal processing techniques to detect, track and classify enemy threats. AAC is the prime contractor for this program and the developer of both the passive sensors and all signal processing (active and passive). In the TDCL Demo program, AAC led a team of 19 industry, academic and Navy lab organizations to produce an effective torpedo defense system for the Navy’s surface and large deck platforms. This team, coordinated and managed by AAC, brought expertise in hardware design, algorithm development, signal processing, software development, system integration, shipboard installation and sea test demonstration. The TDCL system has been installed at a Navy lab and on two PACFLT DDGs.

    AAC's TDCL Mission Package sea trials aboard selected DDG Class destroyers are currently evaluating technology maturity and identifying the probabilities for detection, localization and classification with the ability to process multiple torpedoes and generate an anti-torpedo torpedo launch command - all with a low false alarm rate. AAC's TDCL processor correlates data from the ship's sensors, including active and passive towed sensors, and generates a targeting solution. AAC's TDCL Mission Package program brings the Navy:

    • Improved active and passive acoustic intercept processing
    • Improved command and control display in a Combat Information Center
    • Improved probability for correct classification
    • Improved torpedo defense and ship survivability


  • ASW:
    • AAC’s Anti-Submarine Warfare (ASW) Mission Package employs passive and active sonar signal processing to detect, track and classify enemy submarines.

    The Common Airborne Under Sea Warfare Sonobuoy System (CAUSS) Mission Module is the product of a government/university/industry peer review process (PRP) where the best-of-breed algorithms are evaluated and placed into the baseline. The Surface CAUSS Functional Segment (SCFS) has been deployed as part of the U.S. Navy’s AN/SQQ-89(A)/V15 to support the anti-ship surveillance and targeting mission of that system. SCFS provides processing of active and passive sonobuoys including LOFAR, DIFAR, DICASS, EER and IEER processing.

    The USV Dipping Sonar (UDS) Mission Module gives the Littoral Combat Ship (LCS) the capability to process data from dipping sonar deployed on an Unmanned Surface Vessel (USV). This provides the LCS SeaFrame with distributed situational awareness.

  • USW:
    • AAC’s Undersea Warfare (USW) Mission Package employs passive and active sonar signal processing to detect, track and classify surface and sub-surface threats. The Acoustic Intercept (ACI) Mission Module uses data from Hull ACI, Towed ACI and Calibrated Reference Hydrophones (CRH) to provide the vessel with 360-degree, wide-frequency situational awareness. The USW Mission Package has been deployed on several PACFLEET DDGs and is providing these ships with greatly improved awareness of the environment around and under them.
