Anduril Launches Steelfin Interceptor to Cut Patriot Missile Costs by Two-Thirds
Anduril has unveiled the Steelfin, a modular missile interceptor designed to cost one-third of the current Patriot PAC-3 MSE. The system features interchangeable rocket motors and seekers, allowing it to target threats ranging from low-cost drones to hypersonic weapons. Anduril aims for full-rate production by late 2028 or early 2029, with annual output potentially reaching hundreds of thousands of units. The company is competing in the Army's low-cost interceptor program and believes the design fits requirements for the Future Interceptor program, which seeks a next-generation replacement for the PAC-3 MSE.
