In the context of the recent “Army-2023” forum, the esteemed Malakhit Marine Engineering Bureau [MMEB] showcased once again the model of the diminutive submarine P-750B, colloquially referred to as Serval. It was observed by the discerning eyes of journalists that the submarine’s design had undergone noticeable transformations.

For the sake of exactitude, the light-hull submarine has been modified with the addition of a compact compartment, measuring roughly 8 by 4 meters, to its bow. This compartment has been meticulously engineered to accommodate either one or two mini-subs. They are specifically designed to execute diversionary missions or naval drones. These drones can be employed for both reconnaissance and attack missions, further augmenting the submarine’s operational capabilities.


Within the framework of its primary function, the VNEU gas turbine will serve as the core power plant of the P-750B, as previously elucidated. The Serval, in a noteworthy display of versatility, is installed with not merely 533 mm torpedo tubes, but also a stern launcher. The torpedo tubes possess the capability to launch not only torpedoes but also rockets and mine detection apparatus. The stern launcher, on the other hand, can accommodate up to four cruise or anti-ship missiles, further enhancing the vessel’s offensive and defensive capabilities.

As previously delineated, the Serval’s displacement measures marginally below 1,500 tons, extending to a length of a substantial 65 meters. This formidable submarine possesses the capacity to submerge to an impressive depth of 300 meters, boasting a range that extends nearly 4,500 miles. With an autonomy spanning 30 days, the Serval demonstrates significant endurance. Further enhancing its operational efficiency is the high degree of management automation, necessitating a relatively small crew of just 20 submariners.

Beluga and Kanyon drones

Russia has developed a variety of underwater drones, including autonomous underwater vehicles [AUVs] and remotely operated vehicles [ROVs]. These drones can be used for a range of purposes, from scientific research to military operations.

One type of underwater drone that Russia has developed is the ‘Beluga’ drone. This drone is designed to swim up to a target vessel and attach itself to the hull, where it can then be used to gather intelligence or even plant explosives.

Another type of underwater drone that Russia has developed is the ‘Kanyon’ drone. This drone is a nuclear-powered autonomous underwater vehicle that is capable of carrying a nuclear warhead. It is designed to bypass coastal defenses and deliver a devastating nuclear strike against enemy targets.

Russia’s underwater drones are highly advanced and sophisticated, and they pose a significant threat to the security of other nations. Countries need to develop effective countermeasures to protect against these drones and prevent them from being used for malicious purposes.

Surveillance drones

Russia has several types of underwater drones, including the Bester-1 and the Marlin-350. The Bester-1 is a small remotely operated vehicle [ROV] that can dive up to 300 meters and is equipped with a high-resolution camera and sonar. The Marlin-350 is a larger ROV that can dive up to 350 meters and is designed for deep-sea exploration and research.

These underwater drones work by using a combination of thrusters, cameras, and sensors. The thrusters allow the drone to move through the water, while the cameras and sensors provide real-time data on the drone’s surroundings. This data is transmitted back to a control center, where operators can analyze it and make decisions about the drone’s movements and actions.

Underwater drones are used for a variety of purposes, including scientific research, ocean exploration, and military operations. They can be equipped with a range of sensors and instruments, such as cameras, sonar, and magnetometers, to gather data on the underwater environment. They can also be used for tasks such as underwater inspections, search and rescue operations, and underwater construction and maintenance.

Russia’s underwater drones in the Ukraine war

One of the most commonly used underwater drones by Russia is the Konsul-class drone. This drone is designed for underwater reconnaissance and can operate at depths of up to 1,000 meters. It is equipped with a variety of sensors, including sonar and video cameras, and can transmit real-time data back to its operators.

Another type of underwater drone used by Russia is the Marlin-class drone. This drone is designed for mine clearance operations and can be equipped with various types of sensors and tools, including a manipulator arm for removing mines. It can operate at depths of up to 300 meters and has a range of up to 20 kilometers.


Russia has also been developing a new type of underwater drone called the Poseidon. This drone is designed to be a nuclear-powered, autonomous torpedo that can travel long distances and carry a nuclear warhead. This drone has not been used in the war against Ukraine. However, its development has raised concerns about the potential for a new arms race in underwater warfare.
