Anduril unveils Steelfin modular interceptor missile

Anduril announced the Steelfin interceptor family, built around a two-stage modular design: a common second stage with shared airframe, avionics and software, and a first stage that accepts different solid rocket motors for range and speed. It works with existing Mk 41 VLS and Patriot M903A2 canisters and Aegis and IBCS software, with plans for several thousand units a year and flight testing starting next year.

• Common second stage: airframe, avionics, software and swappable sensors
• First stage accepts different motors for range and speed profiles
• Compatible with Mk 41 VLS, Patriot M903A2, Aegis and IBCS
• Target output of several thousand units a year; flight tests in 2027
