Three Lockheed Martin air surveillance radars will be installed across Denmark in Skagen, Bornholm, and the Faroe Islands, according to a 11 December press release from the Danish Ministry of Defence (Forsvarsministeriet).

The contract for the three radars also provides an opportunity to install a fourth radar in Greenland, according to the MoD release.

While the Danish MoD did not name the radar model, a Lockheed Martin press release on 16 December confirmed that the Danish Acquisition and Logistics Organisation (DALO) had selected the company's TPY-4 radar for long-range air-defence capabilities. The delivery of the radars is intended to strengthen the Royal Danish Air Force and to “support NATO's collective security”, according to Lockheed Martin.

“The current security policy situation requires that the [Danish military] presence and co-operation in the Arctic and North Atlantic be significantly strengthened,” Denmark's Minister of Defence Troels Lund Poulsen said in the MoD press release.

Denmark is the fifth country to select Lockheed Martin's TPY-4 radar, Paul Lemmo, vice-president and general manager of integrated warfare systems and sensors at Lockheed Martin, said in a social media post on 12 December. The three radars are expected to be delivered and become operational “in the coming years”, according to the MoD.

The TPY-4 is an L-band (1,215–1,400 MHz) 3D active electronically scanned array (AESA) ground-based mobile radar, according to the manufacturer's specification document. It has a maximum range of 1,000 km in a stop/stare mode and a range of 555 km in rotating mode. It has the capability to carry out air surveillance, low-profile unmanned aerial vehicle (UAV) detection, ballistic missile search and track, maritime surveillance, and satellite track.
