What Aerostar does

Aerostar International, LLC designs and manufactures a diversified portfolio of aerospace and defense hardware and software, built around three product lines: stratospheric balloons and airships (Thunderhead, Zero Pressure, Super Pressure, Sounding Balloons, and Stratospheric Airships, plus payload recovery parachutes), tactical radar systems (Vista F25/F50ER and HiPointer 100/150, backed by the vStorm sensor fusion software and Smart Sensor Radar Processor), and protective wear (OTS Dry Undersuit, Fuel Handler Coverall, and CWU-83/P Passenger Anti-Exposure Coverall). The company also offers flight operations and contract manufacturing services, including the Box Build Solutions offering launched in September 2025. Its underlying technology combines lighter-than-air platform engineering, proprietary machine-learning-enabled wind models for autonomous navigation (Thunderhead/Thunderstorm), and 30+ years of accumulated radar data powering proprietary target detection algorithms.

Aerostar generates revenue through quote-based hardware sales to defense primes and government end customers, multi-year defense and government contracts (including a five-year, $40.1M U.S. Navy shipboard Air Surveillance Radar program awarded in September 2024), and direct sales to scientific customers such as NASA, with select protective-wear products also available through the GSA Advantage government marketplace. Customers are concentrated in U.S. federal defense and intelligence (U.S. Navy, U.S. Air Force), civil/scientific agencies (NASA, Columbia Scientific Balloon Facility, Harvard University), and selected commercial and integrator partners (Airbus U.S. Space & Defense, Persistent Systems, Silvus Technologies, Alphabet/Google, TCOM). The company operates four U.S. sites (Sioux Falls SD headquarters and 75,000 sq ft manufacturing facility, Sulphur Springs TX manufacturing, Tillamook OR launch operations acquired via Near Space Corporation in 2024, and Arlington VA as Aerostar International's office near the U.S. customer base) and reports missions flown over all seven continents.

Aerostar is privately held by TCOM Holdings LLC following its 2022 divestiture by Raven Industries (which itself was acquired by CNH Industrial in November 2021). Ownership flow and the 2024 Near Space acquisition position the company as the stratospheric-balloon and tactical-radar business unit inside TCOM's multi-layered ISR portfolio of aerostats, high-altitude balloons, tethered drones, and radar systems. The company's history traces back through Raven Industries (founded 1956 by General Mills Applied Sciences engineers) and Aerostar's own 1986 incorporation, giving the business more than 70 years of cumulative lighter-than-air innovation heritage.
