Torpedo Detection - GeoSpectrum Technologies Inc https://geospectrum.ca/product-tag/torpedo-detection/ Specialists in underwater acoustic transducers and systems Wed, 26 Aug 2026 12:18:26 +0000 en-US hourly 1 https://wordpress.org/?v=7.1.4 M670 HMS – Hull-Mounted Sonar https://geospectrum.ca/product/m670-hms-hull-mounted-sonar/ Mon, 05 Jun 2023 16:11:58 +0000 https://geospectrum.ca/?post_type=product&p=7426 The M670 HMS provides surface ships with concurrent, high-performance active and passive sonar capability for the detection, classification, tracking, and localization of underwater targets. It allows the detection of submarines, torpedoes, and mid-water mines and obstacles. Its compact form enables integration in a wide variety of new or upgraded naval vessels. M670 HMS cost-effectiveness makes it a wise and affordable choice for navies seeking a high-performance ASW capability for open-sea as well as littoral environments. Sonar processing is performed by GeoSpectrum’s sensor agnostic RecView system providing flexible waveforms and optimal detection performance and enabling seamless integration with additional ASW systems such as towed array sonar and sonobuoy processor

The M670 HMS can be readily operated for ASW operations and torpedo and mine detection and alert. As a hull-mounted sonar it does not require launch and recovery operations. The HMS can be operated stand-alone or interfaced to the CMS. It can be augmented by and fully interoperable with a towed array sonar such as GeoSpectrum’s Towed Reelable Active Passive Sonar (TRAPS) enabling bi-static and multi-static operations. M670 HMS can also be part of integrated ASW suite including multiple sonars, Torpedo defense systems, underwater communication and Bathythermograph systems.

Completely custom built to meet your requirements, our system maintains the ability to be customized for multi roles after installation with simple software updates. This flexibility keeps this sonar on the cutting edge as compared to other options on the market.

Our M660 has a customizable transmission frequency range and the ability to electronically conduct both vertical and horizontal beam steering. Not only does this provide the capability to detect submarines, but the sonar's high frequency and beam steering ability also provides the capability and fidelity to detect moored mines. A full-sized and compact version (pictured) of the M660 are currently available.
