About Wardstone
Summary
Wardstone builds a modular, mass-producible interceptor platform designed to defend against mid-tier threats, from Group 4 drones to medium-range ballistic missiles. The platform is sized and priced to match the threat, replacing the current reliance on a small number of costly, oversized interceptors that cannot keep pace with adversary production volumes. Each interceptor is assembled from interchangeable modules covering aerodynamic surfaces, propulsion, avionics, divert-and-attitude control, payload, and seeker.
Go-to-market
Wardstone sells to Western defense establishments and their allied partners, competing directly against legacy interceptor programs by offering right-sized kinetic solutions that can be manufactured at scale.
