Always-on intelligence and connectivity for Defense. Icarus builds autonomous, solar-powered aircraft that fly at 60,000 feet for weeks at a time, above the clouds harnessing the power of the sun, but never too close. Acting as a Cell Tower in the Sky, it’s the U-2 spy plane reborn in 2025, except each costs $100K and can be built by the thousands. The future of warfare is persistent swarms in the Stratosphere.

About the Company

Icarus was founded on the belief that the Stratosphere is the Forgotten Frontier and that reclaiming it will define the next era of aerospace and what is possible from the sky.

Tech Stack

We build solar-powered aircraft that fly at 60,000 ft for weeks at a time, delivering persistent, affordable, and scalable presence from this layer of the atmosphere.
