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

[edit]
 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.[7]
  • 3 ordered in January 2024 for USD $65.1 million, to be delivered by end of January 2026.[6]

Potential operators

[edit]
 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]
