“The autonomous carrier of hydro-physical equipment of variable buoyancy (ANGAPP) is used for underwater reconnaissance and electronic warfare. It can be used for seabed reconnaissance for the installation of an underwater object,”
Deputy Designer General Mikhail Kettuev told TASS the craft has no engine and operates due to the pumpover of the liquid in the hull and changing float depending on the position. “For the craft to float, it is necessary to boot it into the maneuvering software of inside computer,” he said.
The payload can include a camera, magnetometers, sonars, and other devices. “The speed is not high, but it can operate for a long time and sail 1.5 km per hour. The submergence depth is 300 meters,” he said.
ANGAPP can survey the seabed in navy bases. “It sees whether unidentified objects have appeared. It can search for mines. Seabed mines usually mud up and look like a stone,” Kettuev said.
