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 Netherlands will replace all of its existing portable ground-to-air radios as part of the broader EUR1.5 billion (USD1.6 billion) 10-year Foxtrot tactical communications programme.

The project, known as the ‘Replacement of Ground-Air Radios', will involve acquiring L3Harris Technologies Falcon III AN/PRC-117G and AN/PRC-163 radios, replacing existing AN/PRC-117F and AN/PRC-152 systems that have been in service with the armed forces since 2002, the Dutch Ministry of Defence (MoD) announced on 25 May.

A number of AN/PRC-167 radios integrated into specific vehicles will also be purchased.

A total of 1,200 new radios will be acquired with up to EUR250 million allocated for the programme, the MoD said.

Turkey's Havelsan will equip the Indonesian Navy's new Arrowhead 140 frigates with its Advent combat management system (CMS), the company told Janes at the Langkawi International Maritime and Aerospace (LIMA) Exhibition 2023 in Malaysia.

The frigates are being constructed by state-owned Indonesian shipbuilder PT PAL, with steel cutting of the first ship in December 2022.

The Arrowhead 140 is the third different class of Indonesian warships planned to be equipped with the Advent CMS. Other classes include 90 m offshore patrol vessels (OPVs) under construction at PT Daya Radar Utama and KCR-60M missile craft built by PT Tesco Indomaritim.

UK defence group Babcock signed a design licence agreement with PT PAL in September 2021, which supported the build of two Arrowhead 140 frigates at the Indonesian shipbuilder's facilities in Surabaya. The Arrowhead 140 is based on the Iver Huitfeldt-class frigate design previously developed for the Royal Danish Navy. The project has been locally branded as the ‘Red White' frigate programme.
