Green Launch delivers industry-leading high-G electronics survival testing through controlled launch and recovery operations at Yuma Proving Ground. Our light-gas propulsion system subjects payloads to extreme acceleration environments—up to Mach 9—giving aerospace, defense, and research teams verified survivability data for electronics, sensors, and onboard systems operating under the most demanding real-world conditions.
Comprehensive launch and recovery testing services for electronics, sensors, and payloads subjected to extreme high-G acceleration environments.
Controlled horizontal test shots using a 7-inch × 55-foot tube at Yuma Proving Ground. Each shot is configured with variable gas charge pressures, release peak pressures, and vehicle weight to characterize electronics survivability across multiple velocity regimes.
Launch electronics and onboard systems to velocities up to Mach 9 using our record-setting light-gas propulsion. Ideal for qualifying avionics, sensors, and structural components intended for hypersonic vehicle applications.
Full-cycle launch and recovery operations delivering instrumented payloads to the stratosphere and beyond. Electronics are exposed to extreme launch G-loads and re-entry environments, with recovered hardware providing direct survivability validation.
Deploy electronics-bearing vehicles into the mesosphere for scientific and communications R&D. Specialized fiberglass RF-transparent vehicle bodies protect onboard electronics while exposing them to the full range of high-G launch and upper-atmosphere conditions.
Tailored test configurations with adjustable gas charge pressures, projectile mass, and velocity profiles. Data sets from each shot series directly quantify the G-load envelope your electronics must survive.
Detailed shot-by-shot reporting covering velocity measurements, acceleration profiles, and electronics functional status post-recovery. Provides actionable survivability data for design iteration and qualification documentation.
We begin with a thorough review of your electronics package, qualification objectives, and survivability requirements. Our team—led by physicist Dr. John W. Hunter—defines the target G-load profile, velocity range, and number of shots needed to generate statistically valid data.
Real-world results from high-G test campaigns that have pushed electronics survivability to Mach 9 and beyond.
Green Launch combines world-class propulsion physics expertise with an established, permitted test range to deliver high-G electronics survival testing no other provider can match.
We hold the record for highest Mach number free-flying scramjet operation at Mach 8, giving your electronics testing unmatched velocity exposure up to Mach 9.
All testing is conducted at Yuma Proving Ground, Arizona—a federally permitted, operational range with proven safety infrastructure and experienced range personnel already in place.
Dr. John W. Hunter, who led the SHARP project at Lawrence Livermore National Laboratory, personally oversees propulsion system design and test execution for every campaign.
Our system executes up to two shots per day with independently adjustable gas pressures and projectile parameters, enabling efficient multi-condition test matrices for comprehensive electronics qualification.
Physicists, engineers, and aerospace veterans driving next-generation launch and testing capabilities.
Chief Technical Officer
Dr. John W. Hunter is a physicist and the technical driving force behind Green Launch's light-gas propulsion platform. With decades of experience in high-velocity propulsion systems, he led the Super High Altitude Research Project (SHARP) at Lawrence Livermore National Laboratory—one of the most advanced light-gas launcher programs ever conducted. At Green Launch, Dr. Hunter directs all aspects of the propulsion system design, test execution, and vehicle development. His hands-on leadership at Yuma Proving Ground has produced a string of milestone achievements, including sustained Mach 9 projectile velocities and a world-record free-flying scramjet operation at Mach 8. His expertise is the cornerstone of Green Launch's ability to deliver credible, reproducible high-G test environments for aerospace and defense customers.
Strategic Outreach
Eric Robinson is a systems scientist and entrepreneur who brings deep expertise in fluid delivery systems for aerospace applications to the Green Launch team. In his strategic outreach role, Eric serves as the primary interface between Green Launch's technical capabilities and its growing customer base across aerospace, defense, and scientific research sectors. He is instrumental in translating complex light-gas propulsion performance data into clear value propositions for satellite manufacturers, government research agencies, and defense contractors seeking high-G testing solutions. Eric's background in fluid systems directly informs his understanding of the propellant management innovations—including Green Launch's industry-leading 91% propellant capture rate—that make the platform both cost-effective and environmentally responsible for repeat test campaigns.
Chairman of the Board
Don Whitney brings a rare combination of operational aviation experience and environmental consultancy to his role as Chairman of the Board at Green Launch. As a former Air Force pilot, Don understands firsthand the performance demands placed on avionics, guidance electronics, and airframe systems under extreme flight conditions—experience that directly informs Green Launch's approach to high-G electronics survival testing. His background in environmental consulting aligns naturally with Green Launch's commitment to sustainable, zero-carbon launch operations using hydrogen and oxygen propellant. Don provides executive-level oversight of company strategy, ensuring that Green Launch's growth from a testing innovator to a full orbital launch service provider proceeds with sound governance and an unwavering focus on safety and mission reliability.
Green Launch's light-gas cannon subjects payloads to extremely high acceleration loads during the launch stroke, consistent with achieving muzzle velocities up to Mach 9 (2.97 km/sec). The exact peak G-load depends on the gas charge pressure, projectile mass, and tube length configuration selected for your test—these parameters are fully adjustable to match your specific survivability test requirements.
