About Wardstone
Wardstone builds a low-cost, modular interceptor platform for air and missile defense. Our platform enables the warfighter to right sizes their interceptors against the threat. This allows us to defeat air-breathing and ballistic missile threats at a fraction of the cost of exquisite interceptors, adding affordable magazine depth to existing air defense systems.
