Advanced Acoustic Concepts to Supply Submarine Torpedo Sonar Components
NEWPORT, R.I. – In a significant development for undersea warfare, the U.S. Navy has awarded a $21.2 million contract to Advanced Acoustic Concepts LLC, located in Washington, for critical electronic components related to the MK 48 heavyweight torpedo, utilized across various U.S. and allied submarines.
This contract, announced by officials from the Naval Undersea Warfare Center Division Newport in late February, encompasses the production of sonar signal transmitters, warhead electronic system assemblies, and test sets tailored for the MK 48 torpedo.
Submarine Armament Overview
The MK 48 torpedo serves as the primary armament for several classes of submarines including the Los Angeles, Virginia, and Seawolf classes, as well as the Ohio-class submarines. It’s also deployed by the Australian Collins-class and Taiwanese submarines. The torpedo is reliant on advanced electronic components, making it a formidable weapon in naval combat.
With a length of 19 feet, a diameter of 21 inches, and a weight of 3,500 pounds, the MK 48 is designed to dive to depths of 1,200 feet, targeting enemy submarines and surface ships from a distance of up to five miles. It can reach speeds of up to 28 knots and is equipped with a 650-pound high-explosive warhead.
Technical Enhancements
The MK 48 torpedo, upgraded significantly since its introduction in 1972, is the U.S. Navy’s principal weapon for engaging underwater threats. The design includes capabilities for wire guidance from the submarine as well as utilizing active and passive sonar systems for target identification and engagement.
Designed to detonate under the keel of a target vessel, this torpedo excels at incapacitating enemy ships. If it misses its target, it can be programmed to circle back for a subsequent attack. The advanced seeker technology comprises an active electronically steered 2D phased array sonar system.
Notably, the latest variant, the MK 48 Mod 7 Common Broadband Advanced Sonar System (CBASS), enhances operational capabilities in shallow coastal waters and harbors in addition to deep ocean environments. Its broadband sonar capabilities improve the torpedo’s effectiveness in challenging acoustic environments, employing modern commercial technologies that allow for flexible upgrades.
Broadband and Multiband Operations
The MK 48 Mod 7 CBASS features multiband operational capability, enabling both active and passive homing. It has advanced counter-countermeasure techniques, ensuring effectiveness against low-Doppler submarines, fast-diving subs, and high-performance surface targets. The system also allows for autonomous fire-and-forget operations, along with wire-guided capabilities for monitoring post-launch adjustments.
This contract will see Advanced Acoustic Concepts execute work in various locations, including Pennsylvania, Virginia, and Washington, with completion expected by November 2027. For further details, visit the Naval Undersea Warfare Center Division Newport or Advanced Acoustic Concepts online.
