Expected Impact:The outcomes should contribute to:
Objective:The rapid emergence of unmanned systems in all military operational domains leads to radical changes in the operational strategies of the armed forces. This topic aims to address these changes and in particular EU capabilities to operate and coordinate unmanned systems in the underwater warfare domain (UWW). These systems are limited by the challenging environment (e.g., low communication range/bandwidth, no satellite navigation, poor visibility) and technology gaps (e.g., incompatible technologies, missing common interoperable standards).
Ongoing research on underwater observation, detection, acquisition and communications is expected to make an evaluation of critical technologies for detection of underwater threats for protection of maritime infrastructures and coastal strategic areas and assets and identify novel technologies for improved situational awareness. Several unmanned underwater vehicles (UUVs) and stationary systems with different characteristics and capabilities exists in Europe, but currently no manned-unmanned teaming and swarms (UTS) technology is available at a satisfactory maturity level to utilise available synergies and to increase the mission performance of combined tactical units for navies. Furthermore, infrastructure elements such as offshore wind farms and power cables with different sensors are to a large extent unused in this context. Current UUVs have challenges regarding performance, incompatible subsystems and lack of possibilities for retrofit capability extensions.
Specific objective
The aim of this call topic is to develop a new generation of Unmanned Underwater Super Systems (UUSS) and networks, where systems and subsystems would reach a technology maturity level of up to TRL 7, potentially TRL 8 on sub-system-level. The goal is to address specific needs of future UTS missions and to demonstrate these systems in an operational seawater environment. Current state of the art UUVs and fixed infrastructure should natively support UTS by application of a common non-proprietary and interoperable standards without the limitations of retrofit solutions.
Depending on the requirements and the concept of operations (manned-unmanned teaming, swarms, squads, detection and manipulation of objects), the UUSS technical elements can differ significantly in size, range, endurance, payload (e.g., mission equipment, communication bottom node or buoy, towed sonar sensors), onboard systems (e.g., communication, navigation, human machine interface (HMI), sonar sensors, optical sensors), level of autonomy and the collaboration capabilities with unmanned vehicles (UxV) from the same or different domains (i.e., air, ground, sea, subsea).
This development should build on results from prior EU underwater research activities, with the aim to design and develop operationally relevant systems employing the available existing research outcomes.
This call topic contributes to the STEP objectives, as defined in STEP Regulation, in the target investment area of deep and digital technologies.
Scope:Requirements and the concept of operations across the EU Member States’ and EDF Associated Countries’ armed forces must be surveyed and analysed to cover a wide range of use cases and to avoid duplications or incompatible technology developments. The outcome should be used as input for conceptional design studies of different UUSS types. This analysis must serve the design. The conceptional design factors should include among others:
The requirements on the new generation of UUSS, systems and subsystems are expected to evolve rapidly in the near future due to high pace of technological innovation in the area in particular employment of new UxV. This development risk must be mitigated by innovative, interoperable, and future-oriented designs with a modular structure to maximise the operational lifecycle, sustainability and consequently minimise costs. The feasibility and suitability of the design should be proven by the assembly of early demonstrators or far-developed prototypes and should include features such as:
Depending on the maturity of the of early demonstrators or the far-developed prototypes, the supersystem (e.g., multiple vehicles and fixed unfractured elements such as bottom nodes and offshore wind farms, power cables), the system (e.g., single vehicle) or subsystem (e.g., vehicle components) may be validated, demonstrated and tested in a relevant or operational seawater environment and may be operated in different concept of operations (e.g., manned-unmanned teaming, swarms, squads). Furthermore, qualification (e.g., non-destructive, destructive) and certification of the UUSS, system and subsystem should be conducted. Possible activities should consist of:

Applicants asked the EU 5 questions about this call and the EU published the answers. They clarify the call documents but do not replace them.
As a general principle, it is required that applicants use only the templates provided on the Funding & Tenders Portal. These templates have been designed in order to capture the information necessary to assess the eligibility of the proposal.
For development actions, as a derogation to this general principle, applicants may replace the following specific templates ‘harmonised capability declaration’ or ‘declaration on procurement intent and common specification’, with alternative forms such as a Letter of Intent (LoI) or a Memorandum of Understanding (MoU), if deemed more appropriate. From an evaluation standpoint, no difference will be made between the available templates and the alternative forms as long as they contain the same level of detail and information and are signed by the competent authorities.
For research actions, none of these above-mentioned templates are mandatory (not part of the eligibility nor the award criteria).

In the “Tpl_Detailed Budget Table” under EDF-2025, when filling in the ‘Purchases’ section of the resource sheet(s) and running “Update content”, only the first line of the “travel and subsistence” is transferred to the Summary and Summary per Activity worksheets, while the added lines and the costs from ‘Equipment’ and ‘Other goods, works and services’ are ignored. What should I do?
Due to a technical issue, for cost category: “C.1Travel and subsistence” in the ‘resource’ sheets, please use only one row and do not use the function/button additional row. Adjust the number of trips, the costs and the description accordingly.

The provision at submission stage of the Procurement intent/common technical specifications declaration and of the Harmonised capability requirements declaration is mandatory if and only if:
-For the requirement of “Procurement intent” and common technical specifications: it pertains to a development action covering prototyping, testing, qualification and/or certification
-For Harmonised capability requirements: it pertains to a development action covering design
However, the template for these declarations is not mandatory: it means that another template than the one provided by the Commission can be used (e.g. template from Member States like a Letter of Intent) under the condition that it contains the same information and the same level of details as the one requested in the Commission templates.
The Harmonised capability declaration confirms that the project proposal is based on Harmonised defence capability requirements jointly agreed by at least 2 Member States/Norway.
When it comes to the provision of the common technical specifications or the harmonised capability requirements mentioned in those declarations, you have the possibility either to provide them 1) at submission stage or 2) to provide them later during the action subject to the following conditions:
-Common technical specifications: if your development action also covers design, as a deliverable resulting from the design activity, before starting the prototyping, testing, qualification or certification activities
-Harmonised capability requirements: if your development action also covers studies, as a deliverable resulting from the studies activity, before the starting the design activity
We would suggest you get in touch with your National EDF Focal Point to guide you to the relevant national authority: defence-industry-space.ec.europa.eu

Due to a clerical error an older version of the Ownership and Control Declaration template was available in some EDF 2025 topics. However, there is no significant difference between the different versions for EDF, so both versions can be used.
