Greece’s armed forces will test unmanned systems developed by domestic companies during the national joint-service exercise “Doureios Ippos (Trojan Horse) 2026,” scheduled for June 8-11 in Thrace and across parts of the Peloponnese and Ionian Sea region, with operations centered at Andravida Air Base.

Eleven companies selected by the Hellenic Center for Defense Innovation (ELKAK) will participate after being chosen from 25 proposals submitted by Greece’s defense ecosystem. The systems fall into four categories: unmanned aerial vehicles for surveillance and reconnaissance missions, loitering munitions, unmanned surface and underwater vehicles, and ground-based counter-drone systems including electronic warfare and communications and GNSS jamming capabilities.

The exercise will allow companies to test and evaluate their systems under realistic operational conditions designed by the armed forces. Military officials, acting as potential customers, will assess whether the most mature domestic technologies meet operational requirements.
