Anduril is taking a modular approach to missile development with its new Steelfin family of interceptors. Instead of designing a separate weapon from the ground up for each mission, the company is building several configurations around one common terminal interceptor. The family is intended to address threats ranging from cruise missiles to hypersonic weapons.
**Adaptable Booster Design:** Steelfin uses a two-stage arrangement in which the first-stage booster can be changed while the terminal interceptor remains common across configurations. Different solid rocket motors can be selected to tailor range and performance to mission needs. The architecture is also designed to accommodate different launch platforms and storage requirements.
This common-core approach is intended to reduce the need for entirely separate designs for each threat type while giving operators greater flexibility in how the interceptors are configured. No further details were provided in the supplied material about specific Steelfin models, test results, operational ranges or service-entry schedules.
