Le futur Rafale sera ultra-connecté pour chasser en réseau

Louis Neveu

En attendant l'arrivée d'un nouvel avion de combat européen à l'horizon 2040, le Rafale va bénéficier d'une importante mise à jour du standard dit F4. Il va renforcer sa connectivité pour évoluer en réseau et s'enrichir de capteurs et d'intelligence artificielle. Explications.

Disponible dans l'armée française depuis près de 18 ans, le Rafale est aujourd'hui considéré comme l'un des meilleurs avions de combat au monde. Il est souvent en lice avec le F-35 américain de dernière génération qui bénéficie pourtant d'un puissant soutien de nombreux pays et des membres de l'Otan. Pour se hisser à ce niveau, l'avion de chasse made in France bénéficie depuis ses débuts de mises à jour importantes reposant sur des standards (F1, F2, F3...). Le standard actuel est opérationnel depuis 2018 et s'appelle F3R. Avec lui l'avion s'est bardé de capteurs, de nouveaux missiles d'équipements laser et des améliorations logicielles.

Le 14 janvier 2019, Florence Parly, la ministre des Armées a remis à Dassault le contrat de développement du nouveau standard F4 du Rafale sur son site d'assemblage à Mérignac. Il en coûtera 2 milliards d'euros pour voir voler le premier démonstrateur mis à jour dès 2025. Il ne faut pas s'attendre à une révolution esthétique de l'avion de chasse. Et pourtant, cette mise à jour est une véritable révolution ! C'est sous la carlingue et dans les datacenters de l'armée que l'innovation va débarquer. Ce standard F4 va faire basculer le Rafale dans l'ère du big-data et de l'hyperconnexion. Sa connectivité va, en effet, être renforcée pour qu'il puisse communiquer et échanger de nombreuses quantités de données en réseau avec tous les véhicules alliés et même les autres forces déployées au sol ou en mer sur le champ de bataille. C'est ce que les militaires appellent le combat collaboratif. Dans tous les cas, la communication doit être fiable, rapide, sécurisée et ce, quelle que soit la distance. Pour cela, il sera équipé d'un nouveau système de radio chiffré renforcé par des nouvelles liaisons satellitaires.

Un saut technologique, un saut stratégique

Le Rafale va également se barder de nouveaux capteurs ou les optimiser, pour détecter les menaces. Ainsi, son radar à balayage électronique sera amélioré, son système de protection avec son brouilleur dernier cri sera renforcé (Spectra). Côté armement, il pourra emporter de nouvelles générations de missiles et une nacelle de visée laser. L'intelligence artificielle va aussi s'inviter à bord. Elle servira de mécano d'appoint pour prédire les opérations de maintenance à venir, ainsi que réaliser des pronostics de pannes et les diagnostiquer. Il faut dire qu'un avion de chasse comme le Rafale doit bénéficier d'importants travaux de maintenance qui viennent le clouer au sol. L'idée est de réduire ce temps de diagnostic et de maintenance.

Ce standard F4 devrait arriver progressivement de 2023 à 2025 au fil des innovations technologiques. Cette importante mise à jour du Rafale va être un premier pas pour dessiner concrètement ce que sera l'avion européen du futur baptisé Scaf (système de combat aérien du futur). Cet avion sera mis au point à l'horizon 2040 par Dassault et Airbus afin de remplacer le Rafale actuel et l'Eurofighter.

CE QU'IL FAUT RETENIR

  • Le Rafale va renforcer sa connectivité et se doter d'intelligence artificielle dans une mise à jour baptisée F4.
  • Les premiers démonstrateurs sortiront en 2025.
  • Ces standards se retrouveront dans l'avion de chasse européen du futur à l'horizon 2040.

  • A compromise is needed on trans-Atlantic defense cooperation

    A compromise is needed on trans-Atlantic defense cooperation

    By: Hans Binnendijk and Jim Townsend The incoming European Commission president, Ursula von der Leyen, will need to work with Washington to defuse a quietly simmering trans-Atlantic defense cooperation issue that, if left unsettled, could do more long-term damage to the NATO alliance than U.S. President Donald Trump's divisive tweets. The United States for years has sought to stimulate increased European defense spending while minimizing wasteful duplication caused by Europe's fragmented defense industry. Europe has finally begun to deliver: Defense spending is up significantly, and the European Union has created several programs to strengthen its defense industries. But in the process, the EU has created a trans-Atlantic problem. These advances in Europe could come at the expense of non-EU defense industries, especially in the U.S. The European Defence Fund, or EDF, established in 2017, is designed to support the cooperative research and development efforts of European defense industries, especially small and mid-sized firms. Three eligible companies from at least three EU countries need to apply in a coordinated fashion to receive project research and development funding, which can be up to a 100 percent grant for the research phase. Plans call for spending about $15 billion between 2021 and 2027 to strengthen Europe's defense R&D and stimulate innovation. Model projects include the Eurodrone and ground-based precision strike weapons. A second related EU program, Permanent Structured Cooperation, or PESCO, also inaugurated in 2017, focuses more on efforts to foster defense cooperation among subsets of European states. Initially envisioned in the 2009 Lisbon Treaty, PESCO is an effort to develop a more comprehensive European defense consistent with EU's common foreign and security policy needs. Thus far, 25 of 28 EU nations have signed up, with 34 modest cooperative projects agreed to by the European Council. The EU estimates that the inefficiency caused by the lack of adequate defense cooperation costs its members between $25 billion and $100 billion annually. These new EU programs, designed to pool and share scarce defense resources, are intended to help address that problem. But the exclusivity of these approaches favor the defense industries of EU members, and the hostile Trump administration rhetoric toward the EU is only supercharging this controversy. President Trump's negative attitude toward NATO and European leaders has undercut European confidence in American trans-Atlantic leadership and strengthened a call in some European capitals for European “strategic autonomy.” Part of this autonomy is developing a more capable and independent European military supported by a stronger European defense industry. A stronger European military capability is a goal shared on both sides of the Atlantic, but not at the expense of defense cooperation. While European leaders understand that they are probably decades away from real, strategic autonomy and military independence, they are shaping the EDF and PESCO approaches to protect European defense industry by being fairly exclusive of U.S. or other non-EU defense industries. This has U.S. defense officials worried. A May 2020 letter to the EU from two senior U.S. officials stated their “deep concern” about the programs' regulations. While current EDF and PESCO programs are small, U.S. officials are worried they will set precedents and will be a model for more ambitious European defense cooperation in the future. They fear not only that U.S. industry will be cut out, but that two separate defense industry tracks will be established that will undercut NATO interoperability and promote further duplication. Some U.S. officials have threatened U.S. retaliation unless changes are made. EU officials respond that these criticisms are excessive. They note that some American defense firms established in European countries will be eligible, that there is nothing comparable to the “Buy American Act” in Europe, that plenty of trans-Atlantic cooperative projects can take place outside of these two EU programs, that the PESCO projects will be guided by both EU and NATO requirements, and that over 80 percent of European international defense contracts go to U.S. firms anyway. They also note that a deterrent to U.S.-EU defense cooperation is that U.S. arms transfer control regulations create potential American restrictions on the sale to third countries of any U.S.-EU cooperative weapons systems that contain U.S. technology. NATO Secretary General Jens Stoltenberg, who seems caught in the middle, has supported both EDF and PESCO, so long as the results fill NATO capability gaps and do not lead to further duplication. Flexibility will be needed on both sides of the Atlantic to defuse this issue before it becomes too difficult to manage. Some opportunities for third-country participation will be needed. Possible approaches to level the playing field include focusing on modifying PESCO, which is still under development in the EU. One suggestion is to create a “white list” of NATO nations not in the EU (such as the U.S., Canada, Norway, post-Brexit United Kingdom and Turkey) that might be invited to participate in selected PESCO projects on a case-by-case basis. This would at least set a precedent that PESCO does not completely exclude third countries. And it would strengthen EU-NATO defense links. Additionally, formal procedures might be established for closer cooperation between the PESCO project selection process and NATO's defense planning process. This will help avoid duplication and identify at NATO those areas where NATO nations outside the EU could cooperate on PESCO projects, The U.S. might also consider amending its arms export control legislation to waive the third-country transfer review requirement for the export of U.S.-PESCO joint projects if the sale would be made to a country to which the U.S. would have made a similar sale. EU internal negotiations on EDF are finished, and changes will be hard to make. Plus, EDF provides R&D funding grants that use European financial resources. While some $118 million in U.S. Defense Advanced Research Projects Agency funds go to European firms, that is about 3 percent of DARPA's budget. So the U.S. might ask for some modest reciprocity from the EDF. But more constructively, DARPA and the EDF might co-fund R&D for joint U.S.-EU projects. The United States has much to gain from a strong European defense industry. Europe has much to gain from cooperation with the U.S. defense industry. All NATO allies need to stimulate defense innovation to compete effectively with Russia and China. Both sides of the Atlantic have much to lose if this issue further disrupts NATO's already shaky political equilibrium. Hopefully von der Leyen's experience as a former German defense minister will help her to understand the urgency and to find a solution to this problem. Hans Binnendijk is a distinguished fellow at the Atlantic Council and formerly served as the senior director for defense policy on the U.S. National Security Council. Jim Townsend is a senior fellow at the Center for a New American Security and formerly served as deputy assistant secretary of defense for European and NATO policy. https://www.defensenews.com/opinion/commentary/2019/10/16/a-compromise-is-needed-on-trans-atlantic-defense-cooperation/

    What Countries Lead In Developing Next-Gen Combat Aircraft?

    Tony Osborne July 29, 2020 Aviation Week's July 16 webinar on the future of combat aircraft mentioned British, French-German and Japanese fifth- and sixth-generation developments. Are there any others on the radar, such as Turkey or South Korea? Will these quieter players be able to pull the rabbit from the hat as the Turks have done with UAVs in Libya and Syria? London Bureau Chief Tony Osborne responds: Had we had more time during the webinar, we would have talked more about developments from Turkey and South Korea—in particular, the Turkish Aerospace Industries TF-X and Korea Aerospace Industries' KF-X. Taiwan and Pakistan are also making investments in fighter technologies, although their progress is not as mature. Turkey benefits from having a capable partner in BAE Systems to support the design process, and I believe they could produce a combat aircraft in the next 5-10 years. The Turkish electronics industry is well advanced, and Turkish Aerospace is growing its capabilities fairly rapidly. The biggest question is around development of engine technologies: Turkey wants an indigenous 25,000-30,000-lb. engine to power the TF-X. Although Turkey is not starting from scratch—given its experience on General Electric engines for the F-16—it has a long way to go before it can produce a reliable, locally developed powerplant. Without that, Turkey will have difficulty exporting such an aircraft. Surety of supply for a foreign engine, especially from the U.S., is doubtful given the political strains between the two countries. In South Korea, it is a slightly different story. Its platform will use a U.S.-supplied engine, and given the close relationship between South Korea and the U.S., there is that surety of supply. Time will tell whether that will change when it comes to exporting the KF-X. With assembly of the first prototype well underway, South Korea appears to be making strong progress. We are still waiting for metal to be cut. https://aviationweek.com/defense-space/aircraft-propulsion/what-countries-lead-developing-next-gen-combat-aircraft
