According to the drone's description, the autonomous carrier of variable buoyancy hydrophysical apparatus is used in systems of surveying, reconnaissance, and electronic warfare in an underwater environment as the carrier of various equipment while fulfilling an assigned task. The system’s devices can be used in conducting oceanographic surveys while preparing an underwater object for installation.

As Gidropribor Deputy Chief Designer Mikhail Kettuyev, the glider lacks its own engine and operates by pumping liquid in the hull and changing its buoyancy depending on its position. "A maneuvering software is required to be entered into a specialized computer installed inside to make it float," he explained.

The new underwater drone can carry a camera, magnetometers, sonars, and other devices as its payload, the deputy chief designer said.

He explained that the speed of its travel is not great. However, considering that it can operate for a long time and if we use figures understandable for us, this is 1.5 km/h. Its diving depth is up to 300 meters.

The latest device can be employed for surveying the sea bottom around naval bases, he specified.
