MANTIS UUV delivers consistent, high-resolution sonar imagery across changing survey ranges.
A Massachusetts-based company has unveiled a new type of unmanned underwater vehicle (UUV), named MANTIS, the UUV integrates side scan sonar technology, and onboard processing.
Developed by Klein Marine Systems, MANTIS combines high-quality imaging with a compact payload architecture. The vehicle is designed to support mine countermeasures, search and recovery, hydrographic and geophysical survey, offshore infrastructure inspection, and environmental mapping missions.
Klein’s integrated approach to sonar design
The vehicle is integrated with Klein’s SmartArray Technology, which embeds key electronics directly within the transducer array to support a more compact system architecture and preserve valuable vehicle payload space.
The company claims that the vehicle is built for UUV platforms where space, power, speed, and data handling are critical.
With advanced processing for dynamic focusing, multiple-look processing, and adaptive beamforming, MANTIS delivers consistent, high-resolution sonar imagery across changing survey ranges and speeds (6-8 knots), creating a strong foundation for machine learning and AI-assisted analysis.
Unmanned underwater vehicle can help operators cover more ground
The vehicle is built for demanding UUV missions, it has motion-tolerant performance and has onboard real time sonar data processing capability, enabling real-time machine interpretation and action.
The company revealed that the vehicle is built for missions where coverage, image quality, and target confidence matter. In its baseline 600 kHz configuration, the system supports up to 150 meters per side, delivering a total swath of up to 300 meters, with 1.0 cm across-track resolution and nominal 10 cm along-track resolution to 50 meters. Additional configurations include operating frequencies of 720 kHz and 850kHz.
The announcement positions the system as suitable for missions requiring both speed and image quality. The company emphasizes compatibility with its SonarPro NXT software platform for data review, playback, and analysis.
Military significance
Sea mines remain a potent option to employ a sea-denial strategy and naval blockades as witnessed in the recent Strait of Hormuz crisis. UUV swarms utilizing synthetic aperture sonar in combination with AI enabled target recognition algorithms can detect, classify, and identify mine-like objects in real-time, reducing the need for post-mission data analysis.
These UUVs are becoming increasingly capable of autonomous operations and performing adaptive search patterns enabling wide area covert operations. Recent trends points towards a hybrid leader-follower concept of operations. Where a more capable but costly leader UUV searches the sea space for detection, classification, and identification of mines, which are subsequently neutralized by a expendable follower.
The current limitation involve the underwater endurance of these UUVs which is directly linked to energy density of the onboard energy storage systems. These drones also remain data bandwidth limited as radio frequency networking suffers from heavy attenuation in the undersea environment.
Securing critical sea-bed infrastructure
The UUVs are increasing being employed to monitor the health and security of critical sea-bed infrastructure this includes oil and gas pipelines as well as optical fiber internet cables. This environment dictates utilization of sea-bed crawler unmanned systems these can be legged, tracked or can employ both for locomotion.
