Anduril unveils family of air defence interceptors

Anduril unveiled Steelfin, a family of surface-to-air interceptors built around a shared two-stage architecture intended to address different air and missile threats. Interchangeable first-stage boosters tailor range and launch configuration, while terminal stages share airframes, avionics, software and flight controls with open interfaces for different seekers. The company says variants will use common production tooling and support launchers including Patriot's M903A2, Mk 41 and Typhon, with integration planned for Aegis and IBCS. Representative air vehicles have completed ballistic testing, flight tests are planned for 2027, and several thousand missiles annually remain a stated production objective.
