Stratospheric birds for defense
Key people at Icarus.
Icarus was founded in 2023 by Henry Kwan (Founder).
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. It’s the modern-day U-2 spy plane, except each costs $100K and is built by the thousands. The future of warfare is in the Stratosphere.

Key people at Icarus.
Icarus is a cutting-edge aerospace startup developing autonomous, solar-powered stratospheric aircraft—referred to as "stratospheric birds"—that operate at around 60,000 feet for weeks at a time. These aircraft provide persistent, low-latency, high-speed connectivity and ultra-high-resolution intelligence for defense and other sectors, functioning as a cost-effective alternative to traditional satellites. Their product, APOLLO, offers continuous coverage above weather and interference, enabling real-time sensing and secure direct-to-device communications over wide areas. This innovation addresses critical gaps in persistent surveillance and communication infrastructure, particularly for defense applications, while also impacting agriculture, urban planning, and other fields. Icarus’s approach promises to reshape the startup ecosystem by pioneering scalable, affordable stratospheric infrastructure that could become a new backbone for global connectivity and intelligence[1][3][4].
Founded in 2023 by Henry Kwan, an aerospace engineer with extensive experience at NASA and Orbital, Icarus emerged from his vision to overcome the limitations of space-based systems constrained by orbital mechanics. Kwan’s background includes building spacecraft and drones, winning major NASA contracts, and holding a Top Secret SCI clearance. The idea for Icarus grew from the insight that the stratosphere offers a unique vantage point for persistent surveillance and communication without the high costs and constraints of satellites. Early traction includes successful prototype flights in 2024 and backing by prominent investors such as Y Combinator and Paul Graham. The company operates out of Los Angeles with a dedicated testing site in the Mojave Desert, enabling rapid iteration and validation[2][6][7].
Icarus rides the growing trend of leveraging high-altitude platforms to complement or replace traditional satellite infrastructure, addressing increasing demands for persistent, low-latency data and communications in defense and commercial sectors. The timing is critical as satellite constellations face challenges of latency, cost, and coverage gaps, while terrestrial networks struggle with interference and infrastructure limits. Icarus’s stratospheric birds offer a new layer of infrastructure that is rapidly deployable, upgradeable, and scalable, influencing the broader aerospace and defense ecosystems by enabling continuous situational awareness and connectivity. This innovation aligns with global trends toward distributed sensing, edge computing, and resilient communications networks[3][4][6].
Icarus is poised to expand its stratospheric grid, Skylink, scaling from affordable initial platforms to larger, longer-endurance aircraft carrying more advanced payloads. Future trends shaping its journey include increased defense reliance on persistent ISR (intelligence, surveillance, reconnaissance), demand for secure, low-latency communications, and the push for cost-effective alternatives to satellites. As the company grows, its influence could extend beyond defense into commercial sectors requiring real-time data and connectivity, potentially redefining how the world senses and connects. The strategic focus on affordability, scalability, and rapid deployment positions Icarus to become a dominant player in stratospheric aerospace innovation, fulfilling its mission to re-establish stratospheric dominance[5][6].
