Defence technology company Anduril is developing its Steelfin interceptor family around a shared core, rather than creating an entirely new missile design for every operational requirement. The family is intended to counter a broad range of threats, from cruise missiles to hypersonic weapons, by combining different first-stage boosters with a common terminal interceptor.
**Two-Stage Modular Architecture:** The Steelfin design separates the booster stage from the terminal interception component. Different solid rocket motors can be used in the first stage to adjust the missile’s range and performance for particular missions. This approach is also intended to support different launch systems and storage arrangements.
By retaining a common terminal interceptor while adapting the booster, Anduril is pursuing a flexible design approach that could serve several defensive roles. The supplied information does not specify individual variants, exact performance figures, production timelines or planned deployment dates.
