• Production of IRIS-C thermal imaging clip-on systems in Zaventem for the Belgian and German Armed Forces under the OCCAR framework contract from 2025

31 March 2026, Belgium. THEON International Plc inaugurated its 100% owned subsidiary THEON Belgium and its state-of-the-art production facility in Zaventem, in the presence of Belgian Minister of Defense Theo Francken, marking a significant step in the Company’s European expansion.
The new facility represents a multi‑million‑euro investment and constitutes a strategic step in THEON’s further strengthening of its position as a leading European defense technology company with growing international reach and a proven ability to support large-scale multinational programs.
The new facility will produce the IRIS-C thermal imaging clip-on system for the Belgian and German Armed Forces under the pan-European OCCAR IRCOD framework contract, signed in September 2025. The initial order is for c.€50 million, with an embedded option of c.€150 million, and mainly requires deliveries in 2026-2027. THEON expects all options to be exercised.
Following the establishment of THEON Belgium on 29 July 2025, THEON has established cooperation agreements with leading Belgian manufacturers in the electro‑optic, metal, and electronics sectors. “This investment strengthens local production, bolsters supply chain resilience, creates tech-driven jobs, and enhances European production capacity, reflecting the rising global demand for our A.R.M.E.D. product line. For me personally, it is a proud moment to return to Belgium after 25 years abroad and contribute to the establishment of a state-of-the-art facility in my home country,” Philippe Mennicken, Deputy CEO and Business Development Director of THEON, added.
Christian Hadjiminas, Founder and CEO of THEON, said: “The high-tech production hub of THEON Belgium in Zaventem combines Belgian industrial know-how in thermal and digital technologies with THEON’s proven electro-optical expertise. Our investment in Zaventem illustrates the advantages of joint procurement programs that strengthen Europe’s operational readiness while creating industrial value across Member States. This is the kind of cooperation Europe should pursue more decisively to reinforce both its defense readiness and its industrial base.”
Theo Francken, Belgium’s Minister of Defense, stated: “THEON’s investment in Zaventem is a meaningful addition to Belgium’s defense industrial base. By establishing local production capacity for IRIS-C in Belgium, this facility leverages domestic capabilities, strengthens Europe’s supply chain resilience, and contributes to closer defense cooperation across Europe.”
