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.
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.
