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 U.S. Army's first battalion-level All-Domain Home Station Training (HST) exercise, STATIC FOCUS 3 at Yakima Training Center from March 3-14, alongside Project Convergence Capstone 5 (PC-C5). The event involved live training with systems for Reconnaissance, Surveillance, Target Acquisition, and non-kinetic effects. A key highlight was the integration and deep sensing capabilities of High-Altitude Balloons (HABs) and solar-powered ultra long-endurance Unmanned Aircraft Systems (UAS).
