The Danish Ministry of Defence Acquisition Logistics Organisation (Forsvarsministeriets Materiel: FMI) has contracted Lockheed Martin to extend the life of the Royal Danish Air Force's two AN/TPS-77 long-range transportable radars.

According to the FMI on 31 May, the two radars will receive a mid-life upgrade (MLU) that was planned as part of the Danish Defence Agreement 2018–2023. The MLU is expected to be completed by mid-2025.

Lockheed Martin was awarded a USD40 million contract in 2005 for the provision of two AN/TPS-77 radars to enhance Denmark's air surveillance capabilities. The systems are stationed at fixed sites within radomes but can be quickly redeployed when required.

The AN/TPS-77 is a 3D active electronically scanned array (AESA) transportable air surveillance radar operating in the 1,215–1,400 MHz frequency band. The system has a range of 470 km and a detection altitude of 100,000 ft. It is in service with a number of countries including Australia, Brazil, Estonia, Indonesia, Iraq, Jordan, Latvia, Malaysia, Pakistan, South Korea, the UK, and the US.

The FMI had not responded to Janes at the time of publication.
