The impact of ongoing global events, from AUKUS to increased tension in the straits of Taiwan, South China Seas and Baltic, highlight profound changes in the global strategic context that places the maritime domain at the heart of efforts to maintain freedom of trade and manoeuvre. Globalisation means the Sea Lines Of Communications (SLOCs) are vital to the economies of the world, pressure on natural resources and climate change will mean contests in the world's Seas and Oceans will escalate including asymmetric and semi-deniable (grey zone) attacks alongside more traditional blue water peer to peer naval combatant operations and humanitarian aid requirements. The future Naval Battlespace is hard to predict with the rate of technology change, it?s safe to say that UncrewedVehicles, Drone swarms, Artificial Intelligence (AI), powered autonomous elements, low observables, hypersonic weapons, Directed Energy Weapons, cyber capabilities will all feature, requiring the structure and composition of naval forces to evolve rapidly. Energy usage and the maintenance of freedom of manoeuvre through energy supply and resupply will be critical. Many of these threats are also opportunities and through pursuing these opportunities the threat will be better understood and mitigated, but economic balance has also got to be pursued. The paper will look at the platform, Marine Engineering and Combat System aspects that will need to develop in order to enable improved effectiveness in the future battlespace and will draw out key threads that should lead to virtuous cost-effective development cycles to prepare naval forces for the future. Unmanned vehicle launch and recovery, survivability, operability, modularity and reduced crewing are themes that will be looked at in the platform. Future fuels and energy management, environmental performance and availability will be looked at through the Marine Engineering aspects and the Combat Systems will cover future effectors, network enabled capability, sensor integration, open architectures as benefit and threat, operator workload and combat system automation. Cross functional aspects will be explored such as the future of survivability, management of damage control in lean manned and autonomous vessels, automation of currently manpower intensive operations and how this may affect personnel and organizational structures.
