In this scientific publication presents an analysis of the existing experience of countries of the world in innovative developments in the technology of building ships, boats and submarines, problems, prospects of their application are revealed and possible ways of their improvement are determined due to technical progress. Creating a modern NAVY requires a lot of time and finance, but also other factors, such as seaworthiness, hull strength, protection against weapons of destruction, secrecy from detection tools, and others. In the design and construction of surface ships, technical ideas and specific solutions must meet the level of development of technology not only of the current period, but also of the forecast for the next 10 to 20 years, which will be aimed at improving the combat and operational qualities of surface ships and submarines. This study examined in detail the modular principle when creating surface ships, which allows you to quickly change the specialization of ships by installing the necessary set of modules of equipment and weapons. The authors turned to the analysis of innovative developments of the Swedish corvette «Visby», which by its properties can be called an invisible ship, the «Marlin-350» underwater vehicle, which corresponds to the latest world trends in the development of underwater apparatus engineering. Also, attention is paid to the development and application of submarines, diesel-electric and strategic nuclear. The authors paid special attention to the use by armed forces of the countries of the world for their arsenals of unmanned systems for various purposes. Three categories were considered: Unmanned Underwater Vehicles (UUV), Unmanned Surface Vehicles (USV) and Unmanned Aerial Vehicles (UAV). The publication also examined the use of ships and boats, powerful guided water cannons as the main engines, which ensures their high speed and maneuverability. Keywords: warship, boat, submarine, propulsion, trimaran, innovation, Ukrainian Navy.
