1
Grid Aero
Country: USA | Funding: $31.6M
Grid Aero develops and manufactures autonomous cargo drones for long-range flights. Its Lifter aircraft is capable of carrying thousands of kilograms of cargo over thousands of kilometers. Combining ultra-simple and low-cost designs with advanced autonomous systems, it can reliably operate in remote or hostile environments, where infrastructure is limited or military operations are taking place. Furthermore, the loss of such a drone does not incur significant losses. Grid's autonomous control system combines classic control systems with modern AI, enabling aircraft to operate intelligently over long distances. It learns from other aircraft in the Grid network and minimizes the need for human oversight. Lifter aircraft operate as a fault-tolerant distributed network. With seamless fleet-wide control, a small ground team can manage dozens of aircraft over vast regions.

Shield AI
Country: USA | Funding: $3.6B
Shield AI is developing X-BAT - large, AI-controlled vertical takeoff and landing fighter jet, as well as the Hivemind - intelligent platform for military applications. X-BAT has a 12-meter wingspan, a maximum range of 2,000 nautical miles, and a 4G maneuvering load factor. It can carry combat missiles and take off and land from ships, remote islands or rugged forward bases, eliminating dependence on traditional infrastructure. Its AI autopilot can operate in conditions of GPS and communications interference. The company is collaborating with the US Department of Defense to develop next-generation intelligence, surveillance and reconnaissance systems. Its Vidar multi-camera system, with day and night vision cameras and sensors, is installed on reconnaissance drones for edge video analytics and mapping. The company is also developing Tracker C-UAS, an intelligent software solution for the early detection of drones in air defense systems using video from electro-optical and infrared sensors.

Hermeus
Country: USA | Funding: $566M
Hermeus is developing unmanned hypersonic aircraft Darkhorse designed for US defense and national security missions. It will be powered by the Chimera combined-cycle turbine engine. At low speeds, it operates in turbine mode, like any jet aircraft. At higher speeds, the incoming air bypasses the turbine, and the ramjet engine takes over control. The company uses a rapid prototyping and testing approach similar to SpaceX. It has already conducted a demonstration flight of its prototype, which is comparable in size to an F-16 fighter jet. Hermeus has also a contract with the US Air Force to develop an Advanced Battle Management System.
4
Nominal
Country: USA | Funding: $182.5M
Nominal develops software that helps manufacturing companies design, plan, execute and analyze military equipment tests on rigs, in chambers, in setups and in the field. Specifically, this platform is used as a flight simulator for military fighter jets. It supports standards such as MIL-STD-810 and DO-160, integrating with systems from Siemens, PTC, Jama, NI, and Keysight. The company serves four of the five largest defense contractors in the US, including Anduril.
5
Radia
Country: USA | Funding: $100M
Radia is building the world's largest military aircraft, the WindRunner, which has a volume 10 times bigger than in Boeing 777 and the ability to land on unpaved runways. It will be able to carry military radars, satellite systems and other mission-ready cargo. According to the company, the WindRunner will be able to take off and land on a 1,800-meter unpaved runway with its maximum payload. Unlike traditional military development programs (according to Radia's plan) WindRunner will make operational entry 10 years faster than next-generation defense concepts. Its first flight is scheduled for 2030.
