Ukraine’s new Freyja interceptor just quietly changed its seeker spec from infrared-only to “combined infrared and radar” — and that one-line update reveals exactly how Ukraine plans to catch Russia’s maneuvering, decoy-carrying Iskander-M missile.
I break down how radar and infrared seekers actually work, why Iskander’s decoys can fool either sensor alone but not both at once, and what this tells us about where missile defense is headed. Freyja hasn’t shot down a ballistic missile yet, but the engineering logic behind this change is the real story.
