Purpose of the flight and payload description
The Lightning Balloon System was developed by Aerostar as a tactical zero-pressure balloon platform designed for rapid deployment and flexible, short-duration missions in diverse environments. It can operate at altitudes ranging from 50,000 to 78,000 feet, with potential extension to a range between 45,000 and 110,000 feet, and is capable of carrying user payloads weighing between 20 to 45 pounds.
In the image at left we can see a scheme of the system (click to enlarge). It allows for maneuverable flight lasting between one to three days and is designed to be launched by a small team of just two personnel from a truck, emphasizing its portability and ease of use. The payload compartment measures approximately 13 by 16 by 18 inches, although larger configurations may be accommodated by special request.
The Lightning system integrates with Aerostar's Thunderstorm software suite, providing a unified platform for command, control, and mission planning compatible with all Aerostar balloon systems. The system is engineered for versatility and has been successfully tested in a variety of challenging environments including austere, maritime, and cold weather settings, and can operate with hydrogen gas.
Payloads are supported with power at +28 volts, offering multiple rails each capable of supplying up to 150 watts, with a total maximum output of 300 watts. Communications capabilities include both Beyond Line-of-Sight (BLOS) and Line-of-Sight (LOS) options via Iridium and optional high-bandwidth mesh or satellite communications. Real-time GPS/INS data is accessible via Ethernet, enabling precise tracking and control.
This particular flight was part of Exercise Arcane Thunder 25 (AT25), held from May 11 to 27 across Germany, Poland, and the United States. Led by the U.S. Army's 2nd Multi-Domain Task Force, the exercise aimed to enhance multi-domain integration and interoperability, testing coordination of nonlethal effects across land, sea, air, cyber, and space. During the exercise were tested new technologies and improveed sensor-to-shooter networks. The exercise supported NATO defense strategies and was aimed to demonstrate strong U.S. commitment to collective defense alongside Allies. The balloons were launched from Fort Huachuca, Arizona.
