Key features

What is it?

The MMT-300 is a compact autonomous underwater vehicle (AUV) intended for diverse underwater tasks. It functions as a mobile sensor platform capable of carrying side-scan sonars, cameras, and environmental sensors to gather high-resolution data in littoral zones.

Who is it for?

It is designed for defense ministries, oceanographic institutes, and commercial entities involved in underwater infrastructure maintenance. It suits teams requiring a portable, rapidly deployable system for harbor security, archaeological research, or ecological assessment.

Key specs

The unit supports a 300m immersion depth, 10-hour endurance, and a 2.5-knot cruise speed. It utilizes an integrated navigation system combining inertial sensors and acoustic positioning to ensure path accuracy during autonomous transit.

How it compares

Compared to heavy-duty AUVs, the MMT-300 offers superior portability and lower operational costs. However, it lacks the extreme depth capabilities and high-speed transit found in larger reconnaissance drones, making it a specialist for coastal and shallow-water operations.

Limitations

The 300-meter depth limit restricts the MMT-300 to continental shelf operations. Its relatively low speed makes it susceptible to strong currents, and mission duration is strictly limited by the capacity of its internal lithium-ion battery system.

FAQ

What is the primary purpose of the MMT-300?

It is primarily used for underwater search, mapping, and surveillance in coastal and inland environments.

Can the MMT-300 be used for mine detection?

Yes, its low-signature design and high-resolution sonar capabilities make it suitable for mine countermeasure operations.

How is the vehicle controlled during missions?

The MMT-300 operates autonomously following a pre-programmed path, though it can receive updates via acoustic communication links.

What sensors can be mounted on the robot?

Common payloads include side-scan sonars, digital video cameras, and various water quality or environmental sensors.

How is the MMT-300 typically recovered?

The vehicle is usually recovered by small boats or surface vessels using specialized retrieval gear or manual lifting after surfacing.
