United States| Country of origin | United States |
|---|---|
| Manufacturer | Lockheed Martin |
| Designer | Lockheed Martin |
| Type | 3D long range detection, AESA radar with GaN TRM (transmit and receive modules) |
| Frequency | 1.215 to 1.4 GHz (L band) |
| RPM | up to 6, or stop/stare mode |
| Range | 555 km (300 nmi) in rotation, 1,000 km (540 nmi) in stop/stare mode |
| Altitude | 0 to 30,500 m (0 to 100,066 ft) |
| Azimuth | 360° in rotation, +/− 45° in stop/stare mode |
| Elevation | −6° to 38° (search elevation), −6° to 90° (track elevation) |
It is a radar capable of multi-mission operation, and performing simultaneously the following work: air surveillance, low profile UAS detection, ballistic missile search and track, maritime surveillance, and satellite track.
In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/TPY-4" designation represents the 4th design of an Army-Navy electronic device for ground transportable surveillance radar system. The JETDS system also now is used to name all Department of Defense and some NATO electronic systems.
The system comprises:
- Transceive Group (TG), the radar system,
- Processor Group (PG), that has the generator for the radar system and that processes the data of the radar,
- Ancillary Group (AG), the means of transport.
Operators
Current operators
Norway (11)- In November 2022, the Norwegian Air Force ordered 8 TPY-4 radars for air surveillance missions, with an option for 3 additional radars. The 8 radars are being delivered until 2025.[3] In September 2024, the option for the 3 additional radars was exercised.[4]
- The Platform Electronic System is built by Kongsberg Defence & Aerospace (KDA).
United States (19)- The United States Air Force selected this radar for the 3DELRR programme (3-dimensional expeditionary long range radar) in February 2022.[5] The plan is to replace the TPS-75 with 35 AN/TPY-4(V)1 by 2028.[6]

Potential operators
Singapore- Lockheed Martin is offering an undisclosed number of the TPY-4 ground-based long-range surveillance radar to the RSAF (Republic of Singapore Air Force) to replace its FPS-117 radar.[15]
