AN/TPY-2

The AN/TPY-2 is a high-resolution X-band radar developed for missile defense rather than ordinary air surveillance. Raytheon describes it as a radar that detects, classifies, and tracks ballistic missiles, while CSIS profiles it as a core sensor for missile-defense architectures. Its development reflects the need for a transportable radar that can be forward based or tied to terminal defense systems such as THAAD.

AN/TPY-2 operates in X band, allowing high-resolution tracking and discrimination of missile threats. Raytheon describes two operating modes: one for detecting ballistic missiles as they rise, and another for guiding interceptors toward a descending warhead. This dual role makes the radar both an early warning asset and a fire-control-quality sensor in layered missile-defense networks.

In service, TPY-2 matters because missile defense is sensor-limited as much as interceptor-limited. A forward-based radar can detect launches earlier, cue other systems, and improve engagement timing. When paired with THAAD or broader missile-defense networks, it helps commanders classify a threat, decide whether to engage, and provide track data accurate enough for intercept planning.
