About Icarus
Stratospheric birds for defense
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 is built by the thousands. The future of warfare is persistent swarms in the Stratosphere.
