Reinventing space launch -- building the world's largest gun to enable launching cargo into space.

Longshot Space is a venture-backed aerospace hardware startup pioneering a kinetic launch system. Simply put, it's a massive underground pneumatic “gun” that accelerates payloads to hypersonic speeds before sending them toward orbit. Led by Mike Grace and Nato Saichek, their lab prototypes have already reached Mach 4–4.6 with small payloads, and the company is now scaling up to a 500‑meter test facility in Nevada to launch 100 kg objects at Mach 5. Supported by investors like Sam Altman, Tim Draper, Starship Ventures, and USAF TACFI/SBIR grants, Longshot’s goal is to reduce launch costs to as low as $10–150 per kg, potentially disrupting traditional rocket-based systems.

Longshot Space tackles a massive market—space launch—using radical physics innovation to significantly cut costs. They’ve de-risked much of the early tech with working prototypes demonstrating real-world hypersonic performance. The company’s path, from lab tests to Nevada-scale systems, enables capital-efficient scaling aligned with Air Force and commercial demand. If successful, they’ll be the first to commercialize orbital mass accelerators, offering low-cost access for satellites, hypersonic testing, and orbital logistics, all while avoiding the complexities of rocket engines. With strong founder credentials, early traction, and proprietary gas-injection valve innovations, Longshot is positioned to upend traditional launch economics.
