01 Executive_Summary

Chantilly, Virginia startup (founded 2021). Founder/Chief Scientist: Dr. F. Douglas Witherspoon. VP: Chris Faranetta. Technology: Magnetized Target Impact Fusion (MTIF) — hypervelocity plasma railguns launch 50-gram fuel capsules at 10 km/s (30x speed of sound), 1 Hz repetition rate, >1 MJ kinetic energy. DD fuel only (tritium-free). Molten lead first wall. Builds on Sandia Z-Machine liner implosion method. Very early stage: $445K total funding. Investors: Virginia Venture Partners, Ecosphere Ventures, Strong Atomics. NSF SBIR Phase I (August 2023). 6 employees. Target: data center power supply. The railgun approach replaces electromagnetic implosion with kinetic impact — alternative to Shiva Star/Z-Machine.
