Small enhanced European UAS

The outcome is expected to contribute to:

• Reduce dependencies on non-European suppliers by boosting the EDTIB and promoting the development of a European solution.
• The emergence of a commonly agreed EU standard for small UAS to allow a wider European application, interchangeability of sensors and modules, together with adaptability to various types of missions.
• Define commonly agreed EU defence requirements for small UAS.
• Reduce the current dependencies on non-European UAS suppliers.
• Reduce the fragmentation of UAS fleets in European armed forces and reduce the procurement and maintenance costs through economies of scale.
• Promote the interoperability between European armed forces.
• Foster an active European market for the development of interoperable and interchangeable sensors.
• Exploit the synergy with other than defence applications.

Despite the extensive use of COTS UAS in recent conflicts and continued technological development, these systems serve the purpose of rapid and relatively low-cost deployment of assets and effectors in times of extreme need. As with all such systems, there is a lack of key requirements and an overall development and sustainability frameworks that meets the real needs of defence users at the tactical level in the EU Member States and EDF Associated Countries. It should be noted, however, that large UAS are always challenging to operate due to their specific needs, e.g., regarding facilities, maintenance and support.

Anticipated advances in miniaturisation and communication protocols are likely to provide sufficient ground for improvements in the area of small UAS for defence applications and their associated payloads, including weapons, without the stringent need for large UAS. Such activities are embedded in very promising prospects for further industrial and operational development.

Against this background, this topic aims to have a direct impact on the tactical operational effectiveness of armed forces in multi-domain operations (air, land and maritime). In addition, the outcome of this topic is also expected to improve the intervention capacity of relevant national or European agencies.

Specific objective

In particular, this topic intends to contribute to address the following specific challenges that small UAS are prone to:

• Low UAS signatures and extended operational ranges;
• Operate autonomously and automatic, including with assisted piloting considerations;
• Miniaturisation of sensors and payloads, including potential weapons and communication systems;
• Operational capability and survivability in contested, congested and challenging (e.g., weather) airspace.

Proposals must address the development of a small UAS with advanced ISTAR capabilities, such as real-time imagery intelligence, and possibly kinetic capabilities, capable of operating in support of the widest possible range of military operations.

In addition, proposals should address the development of a multi-role approach that explores compatibility between different payloads and configurations, in particular through an Interoperable Modular and Scalable Architecture (IMOSA) approach to allow interchangeability of components and interoperability between different solutions, including a “plug and play” capability for sensors and possible effectors.

As the small UAS cannot support sets of different sensors due to weight, space and power limitations, the possibility of standard interfaces should be explored to allow the selection and integration of a variety of specific sensors to be used in different configurations depending on the mission, and to facilitate the use in defence, civil and dual-use configurations.

In addition, proposals may also address the potential synergy for use by law enforcement and other governmental use.

Types of activities

The following table lists the types of activities which are eligible for this topic, and whether they are mandatory or optional (see Article 10(3) EDF Regulation):

Accordingly, the proposals must cover at least the following tasks as part of mandatory studies activities:

• Develop integration with Combat Management System (CMS) in line with a common standard protocols (e.g. foreseen NATO STANAG 4817).
• Study electromagnetic compatibility in order to integrate the system in a combat system without interferences

The proposals must substantiate synergies and complementarities with foreseen, ongoing or completed activities in the field of small and tactical RPAS, notably those described in the call topic EDIDP-ISR-TRPAS-2019 related to Development of a low-observable tactical RPAS with the capability to provide near real time information and with modern self-protection and in the call topic EDF-2023-DA-C4ISR-TRPAS related to Tactical RPAS.

Moreover:

• projects addressing activities referred to in point (d) above must be based on harmonised defence capability requirements jointly agreed by at least two Member States or EDF associated countries (or, if studies within the meaning of point (c) are still needed to define the requirements, at least on the joint intent to agree on them)
• projects addressing activities referred to in points (e) to (h) above, must be:
  • supported by at least two Member States or EDF associated countries that intend to procure the final product or use the technology in a coordinated manner, including through joint procurement

and

• • based on common technical specifications jointly agreed by the Member States or EDF associated countries that are to co-finance the action or that intend to jointly procure the final product or to jointly use the technology (or, if design within the meaning of point (d) is still needed to define the specifications, at least on the joint intent to agree on them).
