Summary

Aerostar (a division of Raven Industries, now under CNH) has built stratospheric balloons and lighter-than-air platforms for over 70 years, historically for the US Air Force and other government customers running communications, data-relay, surveillance, and intelligence missions. Its current Thunderhead balloon line is central to the US Army’s emerging high-altitude sensing effort: an Aerostar balloon (HBAL717) has flown extended missions over the Pacific as part of experimentation feeding the Army’s HELIOS (High-Altitude Extended-Range Long-Endurance Intelligence Observation System) program, and Aerostar has partnered with Airbus U.S. Space & Defense to demonstrate stratospheric systems for US defense applications. Like most companies in this subtopic, Aerostar is not primarily marketed as a drone/missile-detection vendor — it is the balloon/airship platform maker that radar and SIGINT payload suppliers (the Army’s HAP-DS solicitation targets these payloads specifically) would fly on.

Key Facts

  • HQ: Sioux Falls, South Dakota, USA
  • Type: Company — stratospheric balloon and airship platforms; division of Raven Industries (acquired by CNH Industrial in 2021)
  • Product line: Thunderhead balloon systems; broader stratospheric balloon and airship portfolio for “near space” applications
  • Government role: Long-standing US Air Force lighter-than-air platform supplier; active participant in Army high-altitude sensing experimentation
  • Notable flight: HBAL717 launched February 6, 2025 from Sioux Falls, operating over the Pacific Ocean as an IRAD (independent research and development) flight
  • Status: Active; expanding defense partnerships (Airbus U.S., Persistent Systems) through 2024–2026

How It Works

Aerostar’s stratospheric balloons are designed for long-duration station-keeping or wind-navigated drift at altitude, providing an elevated platform for communications relay, ISR, and (per current Army solicitations) radar and signals-intelligence payloads. The Army’s HELIOS program and its HAP-DS (High-Altitude Platform – Deep Sensing) experimentation line explicitly call for small, lightweight (sub-15-lb) radar and COMINT/ELINT payloads flyable at 60,000+ ft to fill gaps in target detection, indicators and warnings, and long-range precision-fire targeting — Aerostar’s balloons are among the flight platforms used to test that concept, with a stated Army goal of demonstrating autonomous swarming for persistent, cost-effective stratospheric presence. The December 2024 Airbus U.S. Space & Defense/Aerostar demonstration specifically tested stratospheric systems for US defense applications, later expanded to include contributions from Persistent Systems (tactical networking).

Notable Developments

  • 2025-02-06: HBAL717 balloon launched from Sioux Falls, South Dakota; extended operations over the Pacific Ocean as part of Army-relevant experimentation
  • 2024-12: Airbus U.S. Space & Defense and Aerostar complete a demonstration of stratospheric systems for US defense applications
  • 2026 (ongoing): Airbus U.S./Aerostar collaboration expanded with contributions from Persistent Systems; Army CECOM soliciting radar and SIGINT payload options for balloon-based HAP-DS/HELIOS experimentation, feeding directly off platforms like Aerostar’s

Limitations

  • Platform, not payload: Aerostar is a balloon/airship manufacturer; the actual drone/missile-detection capability depends on which radar or SIGINT payload is integrated, and current public reporting emphasizes Army experimentation rather than a fielded detection product
  • Government program details are fluid: HELIOS/HAP-DS was in an active experimentation phase as of mid-2026; program scope, funding, and specific Aerostar contract terms should be checked against current Army budget documents before citing as settled fact
  • Long corporate history, less transparency on current commercial terms: As a CNH/Raven division rather than a pure-play startup, detailed financials and contract values are less publicly available than for venture-backed peers in this section
