We are seeking technical and scientific papers that explore new ideas and innovations in the understanding of the changing operational environment, including all aspects of underwater warfare: Anti-submarine warfare (submarine, surface and air), Submarine warfare, Mine warfare (including countermeasures, diving, etc.) and Seabed warfare (including the protection of Critical Underwater infrastructure. 

Papers that explore evolving thinking and concepts associated with the design, manufacture, use and performance assessment of systems, including all aspects of Submarine and other underwater vessels design, manufacture and use and underwater mission networks (sensor systems, data processing and analysis, communications methods and network architectures). 

Maritime Unmanned Systems (MUS) are increasingly capable across the underwater domain. We are looking for academic and technical papers that exploit technology and push the boundaries of capability associated with the design, integration, and operations of unmanned, remotely piloted and autonomous systems (both attack and defensive). We also welcome papers discussing novel operational concepts enabled by MUS developments. 

We also invite scientific and technical papers on submarine, surface, and air-launched weapons, effects and countermeasures designed to operate in the underwater environment, particularly developments in the defeat of difficult targets. 

In addition, we invite academic, scientific and technical papers that may affect any other area of underwater defence, such as the impacts of climate change, developments in surveillance and analysis of the underwater domain and all areas of military diving including underwater engineering and underwater special operations.
