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.

Distributed anti-submarine warfare leverages autonomy and advanced communications and networked sensors that already exist. The distributed ASW concept model leverages a network of smaller, more dispersed sensors and effectors installed on affordable, mass-produced autonomous naval platforms to create a resilient, networked and adaptable ASW architecture. Distributed ASW is critical for operating in contested environments where opponents are investing heavily in advanced submarine capabilities. Distributing ASW capabilities across multiple platforms, the USN can maintain persistent awareness and create redundancy, making it much harder for opponents to disrupt operations.

Sensors

SAMDIS

AAC’s Synthetic Aperture Mine Detection Imaging Sonar (SAMDIS) provides an unmatched Synthetic Aperture Sonar (SAS) capability in a solution scalable to any size Tow-body, UUV. SAMDIS is a 4th generation SAS offering multi-aspect processing of ultra-high resolution SAS imagery, enabling single-track detection, classification, and identification of bottom objects, as well as simultaneous side-looking volume search. SAMDIS outstanding performance provides Automatic Target Recognition (ATR) that eliminates Post Mission Analysis (PMA) and supports Autonomous Mission Execution.

Anti-Submarine Warfare:
Variable Depth Sonar (VDS)

Combined Active and Passive Towed Array Sonar (CAPTAS) 4

CAPTAS 4 VDS is ready now and can be integrated on vessels of opportunity, the Freedom Class LCS, FFG, and select USVs. CAPTAS-4, part of a larger family of CAPTAS systems, provides long range mobile deep-sea sensing currently unavailable in the fleet today. CAPTAS-4 is assembled, integrated, and tested at the Advanced Acoustic Concepts (A Thales DSI company) facility in Lemont Furnace, PA, and is selected to support the U.S. Navy’s Anti-Submarine Warfare Operations.

Medium-Frequency Combination
Active Passive Sonobuoy (MCAPS)

A New Generation of Sonobuoy Technology for a New Threat Environment

MCAPS represents a decisive leap forward in U.S. Navy anti-submarine warfare (ASW) capability. MCAPS delivers:

  • 3x the detection range
  • A modern advanced transducer, enhanced receive array, and next-generation battery system
  • Advanced active waveforms
  • Includes both Continuous Active Sonar (CAS) and traditional single-pulse transmission to improve recognition and tracking in contested environments
  • Integrated narrow band passive capability

Weapon Platforms

MK48

MK48 Warhead Electronic System (WES) Assemblies

This product is the electronic system housed within the torpedo’s warhead section. It is responsible for the digital fusing and firing functions. It uses modern, open-architecture commercial-off-the-shelf (COTS) components that can be upgraded with new software to counter evolving threats.

MK48 Sonar Signal Transmitters

These are critical components of the MK48’s acoustic homing system. They work with the torpedo’s sonar to send and receive broadband acoustic signals, allowing the torpedo to actively or passively home in on its target. Its advanced capabilities help it navigate and track targets in both deep and shallow coastal waters.

MK48 Test Sets

A specialized test set, sometimes referred to as a “confidence test set,” is designed to perform a full system check of the MK48 Sonar Signal Transmitter. It is used for Factory Acceptance Testing and other maintenance, repair, and overhaul activities. AAC designs and produces custom test equipment for the Navy, which includes test stations that are specific to the unique requirements of the MK48 Sonar Signal Transmitter.

ANGLER

AAC’s Mine Warfare Neutralization System (aka: “ANGLER”) is a modular, submersible, reusable, micro-sized, remotely operated vehicle (ROV)/unmanned underwater vehicle (UUV) weapon platform that can either be integrated with a 66mm shaped charge (for skin-to-skin target engagement) or with high-velocity 20mm underwater cargo projectiles (for skin-to-skin up to 10m stand-off target engagement). Employing standard 20mm caliber technology, AAC’s ANGLER system can defeat sea mines from shallow to deep water depths with scalable lethality (low to high-order detonation effects).
