JSTARS

The AN/APY-3(V) JSTARS (Joint Surveillance Target Attack Radar System) is a high-performance, X-band, side-looking airborne radar (SLAR) developed by Northrop Grumman in the United States. Designed to detect, locate, and classify ground targets, it has an instrumented range of 124 nautical miles (230 km). Its passive phased array antenna is housed in a 26-foot radome mounted under the forward fuselage, divided into three 8-foot sections, and can be tilted 120 degrees to either side of the aircraft. Originally developed in the 1970s, the radar received an enhanced update in 2005, becoming the AN/APY-7, a solid-state version incorporating active electronically scanned array technology. Further development ceased due to the increased effectiveness of unmanned surveillance drones utilizing smaller, lighter radars.
