Acute air defense shortfalls in recent conflicts will push U.S. defense contractors toward developing larger families of cheaper, modular weapons that can be produced in greater volume, but this process will take time and encounter other hurdles, even if U.S. systems are still able to retain a central role in allies' procurement as they diversify suppliers. On Oct. 12, U.S. defense technology company Anduril unveiled Steelfin, a new family of lower-cost surface-to-air interceptors designed to defend against a broad range of threats, including drones, cruise missiles and ballistic missiles. The concept is to provide high-end defensive capability at a substantially lower cost than existing premium interceptors, while using a common modular design that can be produced at greater scale. Anduril says it aims to manufacture several thousand missiles annually and integrate them with existing U.S. and allied air-defense networks.
