development – the subsurface robotic system 2R52 "Klavesin-2". There are no such capabilities available so far to the Ukrainian Navy or other military branches and national security services, this despite the fact that domestic industries have sufficient knowledge and expertise in this technology domain. With a 30 years experience in this field, the Scientific Research Institute of Subsurface Technologies at the Admiral Makarov National University of Shipbuilding (NUS), Mykolayiv, has developed 18 unique multipurpose underwater vehicles that have seen uses in research and exploring missions in the Black Sea, Sea of Azov, the Baltic Sea, as well as in the Antarctic (the Weddell Sea). As of this date, the NUS has completed three dozen MRV projects for various uses. Among the most recent ones is the worldwide unique PAR-T – a tethered, unmanned subsurface cargo vehicle for heavy cargo operations. Other projects by the NUS include the autonomous underwater vehicle ANPA-RB equipped with a radio control link; towed underwater vehicle "Glider"; unmanned undersea exploring vehicle "Poshuk" (Ukrainian for "search"); and underwater drone "Inspector" just to name a few. These technologies are all characterized
by high effectiveness and efficiency, performance reliability and compact size. The subsurface drone "Hydrograph", for example, which the NUS built in 2014, has been in continuous operation to date without going out of order or failure. Some of the NUS developed underwater drones have shown high performance during trials conducted in the Sea of Azov area near the city of Mariupol. These vehicles can carry a variety of payload sets customized for specific missions that include, among others, covert surveillance of target underwater areas, mine-hunting, covert resupply runs into deployment zones and back to the home base, and they can be delivered to the operations site at a great distance from the mothership or from the beach. The most recent designs have been developed based on experience with testing experimental MRV prototypes in the Sea of Azov. Importantly, the NUS has mastered advanced technologies like 3D printing for manufacturing parts to save the production cost and make the products more competitive on the market. This allows to consider maritime robotic vehicles as a realistic alternative to employing expensive manned mine-sweeping vessels, at least in littoral waters. The next move would
