The AN/TPY-4, formerly known as the TPY-X, is a ground-based, active electronically scanned array, L-band, multi-function long-range 3D radar for air defense surveillance, built by Lockheed Martin.[1]

It was selected by the US Air Force to replace the AN/TPS-75 radar as part of the 3DELRR (Three-Dimensional Expeditionary Long-Range Radar) program.[2]
