All of F26About Kairox Systems
Kairox Systems combines the speed of aerial drones and the stealth of underwater drones into one vehicle. We can look for mines in a strait, fly out of the water to inspect a coastline, and then engage maritime threats in one go. Joel, Alex, and Jorge all met at MIT. After conversations with warfighters and drone researchers, they decided to create a vehicle unlike any before: A long-range vehicle that is truly amphibious, low-cost enough for one-way swarms, can operate fully autonomously, and can be repurposed on the front lines. Engaged with the Marine Corps and validated with end users across the U.S. and allied militaries.
