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.[2]
| Country of origin |  United States |
|---|---|
| Manufacturer | Lockheed Martin |
| Designer | Lockheed Martin |
| Type | 3D long range detection radar, AESA radar with GaN TRM (transmit and receive modules) |
| Frequency | 1215 to 1400 Mhz (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) |

| Elevation | -6° to 38° (search elevation), -6° to 90° (track elevation) |
It is a radar capable of multi-mission operation, and perform simultaneously the following work:
- air surveillance
- low profile UAS detection
- ballistic missile search and track
- maritime surveillance
- satellite track
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 (9)- The United Stated 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 the TPY-4 ground-based long-range surveillance radar to the RSAF (Singapore Air Force). Singapore is looking to replace its FPS-117 radar.[citation needed]
