Report: V-MAX2 marks a new phase in France’s hypersonic weapons strategy.

On June 26, 2023, France reached a decisive milestone in the field of hypersonics with the successful launch of the V-MAX hypersonic glider from Biscarrosse. This first flight, the result of cooperation between the French defence procurement agency (DGA), ArianeGroup, and Onera, validated key technological choices and marked a European first. By succeeding in stabilising and manoeuvring a vehicle at speeds above Mach 5, France demonstrated its ability to develop capabilities in a sector where only the United States, Russia and China had been active until then. Yet this test was only a first step. France’s ambition is now to move further with VMAX2, followed by the SyLex programme and finally ASN4G, to fully integrate these technologies into a national defence strategy.

Hypersonic glider weapon systems are designed to strike targets by penetrating enemy air and missile defences. Propelled into the upper atmosphere by carrier systems, these gliders reach speeds from Mach 5 to Mach 20. Their trajectories, made unpredictable by extreme manoeuvrability, render them very difficult to intercept. This combination of speed and agility provides a rapid intervention capability at both medium and long ranges. To overcome air and missile defence networks, a hypersonic glider must maintain very high velocity throughout its flight while being able to perform complex manoeuvres in the terminal phase, precisely when it is most exposed to interceptors. This requires a high lift-to-drag ratio, heat-resistant materials and a control system able to respond to extreme conditions.

Aware of these challenges, the Ministry of the Armed Forces appointed ArianeGroup as prime contractor for the V-MAX programme. The company possesses unique expertise in Europe in ballistic launchers, space vehicles and atmospheric re-entry. The first phase of work focused on aerothermodynamic modelling, high-temperature materials and thermal protection, inertial navigation and guidance systems, as well as sensors and antennas. The demonstrator launched in 2023 was designed to test manoeuvrability during re-entry, under severe mechanical and thermal constraints. The flight confirmed structural integrity and the performance of on-board systems, marking a technological success recognised as a first for France and Europe.

The next stage is embodied by VMAX2. This programme, part of the incremental roadmap defined by the DGA, is intended to demonstrate France’s ability to design and control a hypersonic glider equipped with an advanced command system. The vehicle, whose shape and thermomechanical strength are based on several technological breakthroughs, comes very close to an operational system. It will be used to experiment with critical subsystems under representative conditions while anticipating advances in adversary interception technologies. The aim is to achieve a precise understanding of hypersonic flight dynamics to guide future military capabilities.

In continuity with this programme, the SyLex project, presented at the Paris Air Show in 2025, represents an ambition to reach a new threshold. This demonstrator is expected to achieve speeds of up to Mach 16, or around 20,000 km/h. To reach such a leap, France will need to build a sovereign test infrastructure able to reproduce and analyse these extreme conditions. Initial flight experiments are scheduled for 2027, with potential operational integration around 2030. SyLex reflects a clear determination: to provide France with autonomous hypersonic capability, avoiding dependence on foreign infrastructures or technologies.

In parallel, France is preparing the replacement of the ASMP-A airborne nuclear missile with the ASN4G programme. Scheduled for around 2035, this system will be powered by a ramjet engine, combining hypersonic velocity with a strategic payload, thereby ensuring the credibility of French deterrence in the face of advancing missile defence systems. Led by MBDA and Onera under the MIHYSYS contract awarded in 2024, this project is directly embedded in France’s nuclear deterrence doctrine and will be a central element of future strategic posture.

These developments are taking shape in the context of international competition. Russia already fields the Avangard and Kinzhal systems, while China is multiplying tests of the DF-ZF glider. The United States continues several programmes but struggles to convert prototypes into operational capabilities. In this environment, France, despite more limited resources, is seeking to maintain credible status by relying on technological innovation and a reinforced deterrence doctrine.

Ultimately, the evolution of France’s hypersonic sector,  from VMAX to VMAX2, then SyLex and ASN4G,  reflects a progressive but ambitious strategy. Each demonstrator provides vital knowledge, each test is a milestone towards capabilities that could reshape military balances. The coming years will reveal whether France can translate these technological advances into a lasting strategic advantage. One thing is certain: in the global race for hypersonic missiles, Paris has chosen not to remain on the sidelines but to assert its place among the powers shaping the warfare of tomorrow.
