US Army Advances High-Altitude Spy Aircraft and Drone Technology
US Army Seeks High Altitude Spy Aircraft With Drones
The US Army is actively exploring the use of high-altitude platforms for intelligence, surveillance, and reconnaissance (ISR) operations. This initiative is part of a broader strategy to enhance the Army’s multi-layered sensing capabilities, bridging the gap between aerial and space-based surveillance. Historically, the Army has experimented with various high-altitude platforms, including balloons and fixed-wing, solar-powered aircraft. These platforms are designed to operate in the stratosphere, typically between 60,000 and 100,000 feet, where they can provide extended and deep sensing capabilities over large areas.
The focus on high-altitude platforms aligns with advancements in solar-powered aircraft and balloon technology. Companies like Airbus, with its Zephyr drone, are already involved in these developments, highlighting the collaborative effort between military and industry partners to push the boundaries of what is technologically possible. The Army is seeking industry input through requests for information (RFIs) to help define the requirements and capabilities of these high-altitude platforms, including feedback on payload capabilities, platform design, and operational efficiencies.
High-Altitude Platforms and Stratospheric Sensing
The Army is interested in developing and fielding high-altitude platforms such as balloons and solar-powered aircraft. These platforms are intended to carry multi-function payloads, including ISR, navigation warfare, assured positioning, navigation and timing (PNT), network extension, and launched effects capabilities. The focus is on deploying sensor technologies resilient to the stratospheric environment, which includes developing trusted space and trusted sensors to ensure reliable data collection.
One of the key developments is the micro-high altitude balloons (mHABs), which are small, man-portable high-altitude balloons designed for deep sensing inside enemy territory. These balloons are more tactical and require less logistic support, making them ideal for quick deployment in sensitive areas. The Army has conducted theater-level exercises in the Indo-Pacific and European Command areas to test deep-sensing capabilities using high-altitude balloons and fixed-wing platforms. For example, three high-altitude balloons were used as targeting sensors in the 2021 exercise Thunder Cloud in Norway.
The Army plans to start a new program in fiscal 2025 to develop and field a new high-altitude platform capable of deep sensing. This program aims to use novel platforms such as high-altitude balloons and solar-powered aircraft to enhance ISR capabilities. The first funding for the High Altitude Platform for Deep Sensing program is expected in the fiscal 2025 budget, and the Army has released RFIs and plans to release more in the coming months.
“We’re challenging industry to help us figure out how best to deploy intelligence, surveillance and reconnaissance payloads on very high altitude drones.” – Mark Kitz, Army Program Executive Officer for Intelligence, Electronic Warfare and Sensors
Expert Opinions and Industry Context
Experts in the field have provided valuable insights into the development of high-altitude spy aircraft and drones. Mark Kitz, Army Program Executive Officer for Intelligence, Electronic Warfare and Sensors, emphasized the importance of industry collaboration in deploying ISR payloads on high-altitude drones. Brig. Gen. Ed Barker, Program Executive Officer for Intelligence, Electronic Warfare and Sensors, highlighted the affordability and efficiency of high-altitude platforms, balancing low size, weight, and power with high-efficiency sensors.
Andrew Evans, Director of the Army’s ISR Task Force, discussed the tactical nature of micro-high altitude balloons (mHABs), which are smaller and more transportable, making them ideal for quick deployment. The only way to achieve deep sensing in enemy territory is with balloons or ultra-light, solar-powered vehicles, according to Evans. These expert opinions underscore the Army’s commitment to leveraging advanced technology for enhanced surveillance capabilities.
Globally, various militaries are investing in high-altitude platforms to enhance their ISR capabilities, reflecting a shift towards more advanced and persistent surveillance technologies. In the industry context, the focus on high-altitude platforms aligns with advancements in solar-powered aircraft and balloon technology. Companies like Airbus, with its Zephyr drone, are already involved in these developments, highlighting the collaborative effort between military and industry partners to push the boundaries of what is technologically possible.
