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]
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
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 (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] - 2 ordered in April 2022 for USD $75.0 million.[7]
- 4 ordered in February 2023 for USD $84.9 million.
- 3 ordered in January 2024 for USD $65.1 million, to be delivered by end of January 2026.
