  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]
