Russia Displays Klavesin-1RE – Autonomous Underwater Drone with Diving Capability of 6,000 Meters


Known to be superior in submarine technology, it is not difficult for Russia to develop an underwater drone or AUV (Autonomous Underwater Vehicle). In tight competition with the United States and Western Europe, in fact many types of AUV have been launched by Russia.


And at the 2023 International Maritime Defense Show in Saint Petersburg, Rosoboronexport JSC (part of the Rostec State Corporation) as the official agent for Russian arms sales, will exhibit an underwater drone – autonomous unmanned underwater vehicle (UUV) Klavesin-1RE.

The Klavesin-1RE is designed to carry out surveillance and search operations, inspecting bottom objects at depths ranging from 5 to 6000 meters while operating in autonomous mode and also in correction mode via the hydroacoustic communication channel of the transport ship.

“Rosoboronexport is closely watching trends in the global arms market,” said Alexander Mikheev, General Director of Rosoboronexport, in a press release. “The main focus now is unmanned military equipment, robotic systems. Unmanned vehicles and systems are expected to be used in all environments.”

Among the advanced high-tech systems developed by the Russian defense industry is the Klavesin-1RE (literally: “Harpsichord”).

Klavesin-1RE makes it possible to carry out a bottom topographic survey using sonar and identify objects worthy of detailed inspection on board the carrier. This underwater drone is capable of examining underwater objects in detail using sonar, TV and electromagnetic sensors, as well as automatically identifying and tracking extended objects using TV and electromagnetic locators.

In addition, the drone designed by the Russian Institute of Marine Technology can perform an acoustic profile of the seabed and measure environmental parameters across the entire range of operational depth and ground speed.



The Clavesin-1RE system can be operated in all possible hydrological conditions, in Sea State 3 and at water temperatures from -4°C to +35°C. Launch and recovery operations involving the AUV can be carried out at wind speeds of up to 15 meters per second, and the AUV system can be stored and transported at ambient temperatures from -50°C to +70°C.


"With its technical specifications, Klavesin-1RE can be operated both in hot tropical climates and in the Arctic region," added Alexander Mikheev. "Rosoboronexport is ready to consider various delivery options for the Klavesin-1RE UUV as a final product, as well as drone cooperation through industrial cooperation for the benefit of the navies of partner countries.
