Wardstone is a space defense technology company founded in 2025, headquartered in San Francisco. The company designs, builds, and deploys satellites equipped with kinetic interceptors to detect, predict, and neutralize hypersonic and ballistic missile threats.
The company's primary product is the Hailstorm constellation, a satellite system intended to provide global, redundant coverage against missiles in flight. Wardstone aims to deploy the constellation by 2028. During its time at Y Combinator, the team built and demonstrated a live ground-based missile intercept system.
Wardstone's technical work spans satellite design, kinetic interceptor systems, missile detection, and missile prediction. The company is aligned with the U.S. government's Golden Dome initiative and operates within the space defense and missile defense verticals, with potential customers including the Department of Defense, Space Force, Air Force, Navy, and Army.
