Onboard RF, optical or infrared seekers that guide an interceptor to its target in the final phase of flight.

Assessment

Case for · why it matters

The seeker drives both the cost and the accuracy of a low-cost interceptor; cheaper seekers let missiles work with less capable, cheaper radars.

Case against · the skeptic’s view

Seeker suppliers depend on integrators to win programs, and low-cost seekers must still hit small, fast, low-signature targets.
