Improvement in detection capabilities in SBW scenarios.Improvement of reaction capabilities in SBW scenarios.Improvement in EU technological autonomy for critical seabed infrastructure protection.Improvement of design of integrated defence systems for SBW scenarios operating at deep water depths. Objective:Following the emergence of geopolitical instability in Europe and recent acts of sabotage on underwater critical infrastructures, it is evident that the vulnerability of assets such as underwater strategic pipelines, cables, communication backbones and offshore infrastructures, requires resolute measures to ensure their safety and resilience with a specific focus on Seabed Warfare (SBW).

Next generation silent submarines are an example of new forms of threats that need to be countered by effective response capabilities supporting the various defensive missions. Other examples of threats are unmanned vehicle (UxV) carriers that can target energy pipelines, spoofing data from the submerged communication backbones and cutting power energy cables.
International cooperation projects under the auspices of the EU (PESCO, EDF) and NATO (JCG MUS, Smart Defence) have already been initiated to counter these emerging threats.
However, further dedicated research focusing on the evaluation of potential technologies to cope with the above needs is necessary. In particular, this research must prioritise on delivering of technologies to EU defence capabilities that are expected to enable solutions for monitoring and defending underwater critical assets as well as responding to threats in deep waters (water having a depth greater than 200 metres) up to 6000 meters (m) in depth.
Specific objective
Due to a growing number of sabotage acts on critical underwater infrastructure, SBW has gained a very high level of interest for many EU navies. It is therefore necessary to be able to counter the various threat types operating in deep waters up to 6000 m in depth. Most of today's surveillance and reaction systems currently in service in Western navies have been developed to operate at limited depths, and not in the immediate proximity of the seabed. For many of these systems, extension to new operational requirements is hampered by several technological barriers. For example, with existing technologies the maximum operating depth of vehicles based on a pressure-resistant hull (such as traditional torpedoes) is insufficient for new and emerging operational scenarios.
An extensive and precise research activity, focused on "great-depth enabling technologies", could represent an important intermediate step towards an optimised and more efficient future SBW. The results of the research activity could facilitate and speed up the design of new systems specifically conceived and optimised for the operation in the new operational scenarios. At the same time, these new great-depth technologies could facilitate the adaptation of current systems to new operational requirements.
Proposals are expected to reach technology readiness level (TRL) 5.
Scope:The aim is to progress in undersea operations (e.g., SBW) in deep waters up to a depth of 6000 m, with a concept phase to study and evaluate technologies suitable for platforms and payloads to allow unmanned underwater vehicles (UUV), detection systems, warning systems, communication systems, and weapon systems to perform deep water undersea missions (e.g., SBW missions), or even to be applied on fixed elements such as monitoring systems.
The proposals must identify defence use cases and justify the relevance of the proposed technologies to be addressed with respect to these use cases, taking into account the wider landscape of potential solutions for these use cases and the deployment costs.
Layered defensive depth must be formed and critical areas must be identified where monitoring and protection of the critical undersea infrastructure must be extended.
