ArianeGroup carried out the second launch of SyLEx, its sounding-rocket system known as the Système de Lancement d'Expériences (Experiment Launch System), on November 4, 2026. According to the company's official statement, it was the system's first operational flight, following a successful demonstration flight on November 28, 2025.
The single-stage version lifted off from the DGA Missile Testing Centre in Biscarrosse, France, under the direction of the French Defence Procurement and Technology Agency (DGA). It carried an experimental payload for the DGA and for the French Ministry for the Armed Forces and Veterans. ArianeGroup is the industrial prime contractor for the system on behalf of the DGA.
What SyLEx does
SyLEx is not an orbital launcher: it is a suborbital flight-test platform. It was created to test equipment in real conditions ahead of larger missions, with applications such as atmospheric re-entry experiments and microgravity research, for civilian and military customers in the European market.
Developed in under three years, the system is presented by ArianeGroup as France's first sovereign suborbital capability — a domestic means of testing, without relying on a foreign launcher for this kind of experiment.
Two models and a dedicated pad
The system combines two sounding-rocket models, single-stage and two-stage, plus a dedicated launch pad. According to the November 4 statement, payload capacity reaches 600 kg and altitudes range from 200 to 400 kilometres, depending on configuration and mission. A single flight can carry several experiments.
On the official product page, the single-stage version (Block 1) is 10 metres tall, 0.7 metre in diameter, carries 300 kg and offers 4 to 5 minutes of microgravity. The two-stage version (Block 2), scheduled to fly by 2027, is 15 metres tall, carries 600 kg and offers more than 6 minutes of microgravity.
For ArianeGroup, the flight demonstrates the ability to provide a sovereign suborbital test platform. Vincent Péry, the company's Director of Defence Programmes, said in the statement that the flight was particularly significant because it carried a major experimental payload for the DGA and the ministry, and that work continues on the two-stage version.
