   Anduril Unveils Steelfin Interceptor Missile Family

   Military technology company Anduril Industries has revealed a new family of interceptor missiles called Steelfin, designed to provide a more affordable alternative to PAC-3 missiles. According to company executives, the modular system uses a shared interceptor core with interchangeable boosters to counter a wide range of aerial threats, delivering substantial capability at a fraction of traditional defense costs. The American defense tech startup challenges legacy defense companies by aiming to cut missile defense expenses through artificial intelligence and advanced autonomous systems engineering.

   Why it matters

   Founded in 2017, Anduril has grown rapidly with a private valuation of $61 billion as of May 2026. The company specializes in building advanced autonomous systems, unmanned aerial systems, and networked command and control software for the U.S. Department of Defense and allied forces. The introduction of the Steelfin interceptor represents the latest effort by venture-backed defense tech startups to disrupt traditional defense manufacturing during a push for military reindustrialization.
