What Klein Marine Systems does
Klein Marine Systems is a U.S.-based marine technology company founded in 1968 and headquartered in Salem, New Hampshire, that designs and manufactures advanced side-scan sonar systems for hydrographic, offshore, and military customers. Its product portfolio comprises three core offerings: the System 5900, an ultra-high resolution multi-beam side scan sonar with integrated gap filler and co-registered bathymetry for high-speed mine countermeasures (MCM) and surveillance; the UUV System 3500, a low-power dual-frequency side scan sonar with onboard processing designed for integration with autonomous and unmanned underwater vehicles; and the MANTIS UUV, a next-generation unmanned underwater vehicle platform leveraging the proprietary SmartArray Technology™ to deliver consistent high-resolution imaging at mission speed.
The company's underlying technology centers on transducer design, multi-beam sonar processing, and bathymetric co-registration, packaged into hardware systems that are deployed on naval vessels, AUVs/UUVs, and survey platforms globally. Klein serves a primarily defense-oriented customer base (Military & Defense is the lead vertical) with secondary use cases in offshore renewables and unexploded ordnance (UXO) detection, salvage and wreck hunting, and search and recovery operations. Its go-to-market is a direct enterprise field-sales motion with around-the-clock global technical support, on-request in-person training, and a customer portal—consistent with the long sales cycles and mission-critical nature of defense and hydrographic procurements. Pricing is quote-based and structured around multi-year contracts.
Klein operates as a wholly controlled subsidiary of General Oceans ASA, a Norwegian maritime technology company that completed its listing on the Oslo Stock Exchange in March 2026. Revenue mechanics therefore include one-time and recurring hardware sales of sonar systems plus professional services revenue from technical support and training; specific pricing and revenue figures are not publicly disclosed.

Klein Marine Systems competitors and assessment
Company assessmentDirect peers
- iXblue (iXblue Sonar): iXblue (now Exail) manufactures sonar systems, inertial navigation, and autonomous underwater vehicles for defense and hydrographic customers. Directly comparable to Klein in UUV-integrated sonar payloads and high-resolution seabed imaging.
- Sonardyne: Sonardyne designs marine acoustic instruments for navigation, positioning, imaging, and communication. Comparable to Klein in defense and offshore survey customers and underwater acoustic sensing capability, though with broader product breadth beyond side-scan sonar.
- EdgeTech: EdgeTech manufactures side-scan sonar, sub-bottom profilers, and bathymetric systems for military, hydrographic, and commercial survey markets. It is the most direct competitive peer to Klein, offering overlapping product categories in high-resolution shallow-water sonar imaging.
- Kraken Robotics: Kraken Robotics develops high-resolution seabed imaging sonar, including synthetic aperture sonar (SAS) and underwater robotics for defense and survey. Directly competes with Klein in UUV-mounted high-resolution sonar and Mine Countermeasures (MCM) applications.
- NORBIT Subsea: NORBIT Subsea provides multibeam echo sounders and underwater mapping systems for hydrographic and offshore markets. Competes with Klein in survey-grade underwater imaging and bathymetry, particularly for offshore renewables and coastal survey applications.
Broad incumbents
- Saab Seaeye (Saab Dynamics): Saab Seaeye designs and manufactures electric underwater robotic systems for defense and commercial customers. Comparable to Klein in UUV/ROV payload integration and naval MCM, though primarily a vehicle systems integrator rather than sonar specialist.
- Kongsberg Maritime: Kongsberg Maritime is a major supplier of underwater sensor systems, AUVs (HUGIN), and sonar payloads for defense and offshore markets. Competes with Klein as a vertically integrated provider with broader maritime system offerings and a much larger R&D footprint.
- Thales Underwater Systems: Thales supplies sonar systems, mine countermeasures, and naval combat systems to military customers worldwide. Competes with Klein in naval MCM and surveillance programs, though at a much larger scale and with broader defense portfolio integration.
- Teledyne Marine: Teledyne Marine is a large-scale provider of imaging, instruments, and underwater vehicles across the marine industry. Competes with Klein across multiple marine sonar and survey categories but with a much broader product portfolio and serving a wider range of customers.
