Electro Optic Systems used the opening of the Eurosatory defense exhibition in Paris on June 15, 2026, to present its enlarged counter-drone business, built on its acquisition of MARSS, and to pitch defense buyers a single package covering detection through to defeat.
The acquisition, first announced on January 12, 2026, gives EOS the piece it did not previously make. The company has long supplied effectors, including its Slinger remote weapon system, R150 and R500 turrets, and high-energy laser weapons.
MARSS brings NiDAR, an AI-enabled command and control and sensor-fusion platform that ties detection, tracking, and engagement into one operating picture. It also brings a defeat option of its own, the Interceptor-MR, an autonomous hit-to-kill drone built to ram Shahed-class targets and slated for production in 2026 at under $50,000 a unit.
EOS now spans guns, lasers, and an interceptor under one command system, though the integration it is selling has yet to be proven at scale to customers.
EOS is anchoring the unit in Europe, confirming on June 15, 2026, an investment of more than €10 million ($11 million) to establish its counter-drone command-and-control hub in Nice, France, with up to 150 jobs over three years. MARSS continues to trade under founder Johannes Pinl as “MARSS, an EOS Company.”
Demand in a crowded field
EOS is betting on a market inflated by drone warfare in Ukraine and the Middle East. The company said customer inquiry levels have stayed at sustained highs, driven by conflicts in Europe and the Middle East. MARSS booked roughly €102 million in new orders in May 2026, anchored by a country-wide drone defense contract in the Middle East.
It is not alone. European primes are assembling rival layered architectures, as seen in the Airbus and Alta Ares counter-drone partnership, under which Airbus acts as integrator, connecting a counter-drone firm’s interceptors into its Fortion IBMS command suite. Whether EOS can convert a trade-show launch into the larger, integrated programs it is targeting will be clearer once the combined order book is tested.
