System 5900

Klein Marine Systems’ military side scan sonar portfolio includes the Klein 5900.

The Klein 5900 is a robust, field-proven sonar system designed to support defense, survey, and offshore operations. By combining high-speed, high-resolution sonar with embedded electronics and AI-enabled processing, the 5900 delivers detailed underwater imagery, supports target detection, and improves survey efficiency.

Key Capabilities

• High-speed, high-resolution survey: Provides 3.2 cm across-track resolution and 0.07° along-track resolution at survey speeds up to 12 knots, supporting rapid data collection with near-SAS-level detail.

• Enhanced bottom coverage: A nadir gap-filler capability supports continuous seafloor coverage and can reduce the need for repeat passes.

• Integrated bathymetry: Co-registered bathymetry adds topographic context to support review and decision-making.

• Motion-tolerant design: Engineered to maintain image quality in more challenging sea states.

• Automatic Target Recognition (ATR): ATR powered by Spectral AI supports in-field detection and classification of mines, UXO, and other underwater objects.

Operational Advantages

• Mine Countermeasure (MCM) operations: Supports efficient surveys with near-SAS-level detail across a range of operating conditions, helping reduce overall MCM survey time.

• Surveillance missions: Enables rapid, high-resolution seafloor surveys with enhanced bottom coverage, in a system engineered for challenging environments.

• Geophysical and UXO surveys: Supports offshore energy and infrastructure surveys with high-resolution imagery and integrated data outputs aligned with current project requirements.
