Anduril Industries has unveiled its new Steelfin family of interceptor missiles, designed to provide a more affordable alternative to existing missile systems, including the PAC-3. The Steelfin missiles aim to counter a range of threats, from ballistic to hypersonic, and are pitched at about one-third the cost of the Patriot systems. This launch challenges established defense contractors by offering a customized and modular approach to surface-to-air and air-defense capabilities.
