European defense newcomer Stark is firing up the battlefield with “Virtus,” its first artificial intelligence (AI)-enabled loitering munition featuring vertical take-off and landing (VTOL) capability.
Officially named the One-Way Effector–Vertical (OWE-V), Virtus is purpose-built for modern conflict — fast, smart, and ready to strike.
Fully electric and optimized for rapid deployment, the drone brings together advanced hardware and software capable of adapting to shifting battlefield conditions in real time.
Driven by AI, Virtus can identify, track, and engage targets with pinpoint precision, even in GPS-denied or electronically contested environments.

Stark says its focus is simple: take lessons from recent conflict, including the war in Ukraine, and turn them into combat-ready capabilities made in and for Europe.
“The nature of conflict is changing, and Europe and NATO are facing immediate and significant threats,” the company stated, adding that the goal is to “deliver cutting-edge capabilities, created and tested in Europe, to defend Europe.”
What Virtus Brings to the Fight
Virtus cruises at speeds of 120 kilometers (75 miles) per hour, with the ability to dive on targets at up to 250 kilometers (155 miles) per hour.
It supports a payload of up to 5 kilograms (11 pounds), stays airborne for up to an hour per battery cycle, and can engage targets at ranges of up to 100 kilometers (62 miles).
Its VTOL design allows for quick launches — often in under five minutes — from tight spaces or rugged terrain.
Once airborne, its autonomous AI core enables it to adapt mid-mission, avoid detection or disruption, and complete objectives with minimal operator input.
When no viable target is detected, Virtus can return and land safely for reuse, offering both efficiency and cost-effectiveness in the field.
