Stratolink will test the Argus stratospheric UAV prototype in Spring 2026. The UAV, with a 40-meter wingspan, can fly for up to 40 days and carry a 40-kg payload for reconnaissance and Internet distribution.

The drone is designed to operate using solar panels, batteries, or hydrogen fuel cells, allowing functionality in diverse environments, including the Arctic. Production of a larger model is planned for the next year, contingent on funding. The testing will assess aerodynamic performance and engineering solutions.
