Who's Who Defence Innovation Instruments
Accroche

In Europe, with Russia’s war of aggression against Ukraine showing little sign of abating, a persistent gap remains between security needs and defense spending. According to a 2006 commitment enshrined at the 2014 Wales NATO summit, the North Atlantic Treaty Organization (NATO) members should disburse no less than 2% of their national gross domestic product (GDP) on defense, out of which 20% is to be spent on equipment and research and development. In 2024, only 23 Allies out of 32 are expected to meet or exceed this target, though a significant improvement from only three in 2014. This total includes the United States (US) devoting 3.38% of its GDP to defense, constituting almost 70% of all NATO member defense spending combined.

EUDIS, HEDI and DIANA are three recent policy instruments meant to encourage defense innovation in Europe, and beyond. Fielded by the European Commission, the European Defence Agency (EDA) and the North Atlantic Treaty Organization (NATO), respectively, these seemingly comparable defense investment instruments underline key challenges confronting European defense

They stand for competing national visions: European supranational, intergovernmental, as well as transatlantic defense perspectives in differing and diverging combinations. 

EUDIS, HEDI and DIANA highlight the persistent gap with European defense objectives set 20 years ago, most notably the divide between stated ambitions and actual means invested.

Security Studies Center
Accroche centre

Heir to a tradition dating back to the founding of Ifri, the Security Studies Center provides public and private decision-makers as well as the general public with the keys to understanding power relations and contemporary modes of conflict as well as those to come. Through its positioning at the juncture of politics and operations, the credibility of its civil-military team and the wide distribution of its publications in French and English, the Center for Security Studies constitutes in the French landscape of think tanks a unique center of research and influence on the national and international defense debate.

The Defense Research Unit is a program that aims at stimulating the strategic debate by dealing with subjects at the junction of the “technico-operational” and the “political-strategic”. A unique structure in France, it brings together civilian researchers and “military fellows” from each of the three armies to produce work on defense policies, the capability and strategic adaptation of armies, and foresight on tomorrow's conflicts.

Confronting Russia’s High-Velocity Arsenal: European Challenges and Solutions

Date de publication
11 September 2026
Accroche

Since February 2022, Russian missile and long-range drone strikes against Ukraine have served as near-daily reminders of what European states could face in a war with Russia. The same weapon systems battering Ukrainian infrastructure and population centers would be directed against European military and civilian targets in any confrontation between Russia and NATO. As Russian missile production expands and its arsenal diversifies, Europe must confront an uncomfortable question: how to deter, and if push comes to shove, fight Russia's long-range strike arsenal?

From Corsairs to Private Military Contractors. Nonmilitary Maritime Actors and the Historical Continuities of Naval Warfare

Date de publication
26 August 2026
Accroche

Since late 2023, several Houthi attacks on commercial shipping have involved privately contracted armed teams conducting defensive engagements and coordinating immediate response efforts, often in the relative absence of regular naval forces during the immediate hostilities at sea. These cases highlight a strategic tension that increasingly confronts modern navies. On the one hand, they are expected to conduct persistent, low-intensity maritime security tasks such as counterpiracy, maritime policing, and the protection of commercial shipping. On the other hand, they face renewed pressure to prepare for high-intensity conflict against peer and near-peer adversaries amid the return of great power competition.

Framework Nation: A European Challenge and French Ambition

Date de publication
10 June 2026
Accroche

First appearing in the early 2000s, the framework nation concept follows several distinct rationales, whether it refers to a country assuming the leadership of a military operation, directing a multinational capability project, or commanding a permanent force structure. In every case, the country that takes on this role fully intends to derive from it additional politico-military influence.
