The Danish Defence Acquisition and Logistics Organization (DALO) has selected the next-generation TPY-4 ground-based air surveillance radar, developed by Lockheed Martin, with the aim of strengthening Denmark’s long-range air defense capabilities. With this decision, Denmark becomes the fifth nation to adopt the system, joining a growing group of NATO partners integrating this advanced radar technology.
The selection includes the delivery of three TPY-4 radars, with an option for a fourth unit. These systems will be assigned to bolster the Royal Danish Air Force and contribute to the collective security of the Atlantic Alliance. The TPY-4 enables real-time detection and tracking of aerial targets and features an open architecture that facilitates integration with existing air and missile defense systems.
Regarding the selection, Rick Cordaro, Vice President of Radar and Sensor Systems at Lockheed Martin, stated: “This is a major step forward in integrated deterrence. The advanced capabilities of the TPY-4 radar enhance interoperability across allied air defense networks, ensuring that Denmark and its regional partners can respond rapidly to evolving threats.”
The TPY-4 is a solid-state, phased-array radar designed to deliver mobility, reliability, and global deployability. Lockheed Martin radars are currently in service with more than 45 countries across six continents, reflecting their broad adoption in diverse operational environments.
The TPY-4 program is supported by close cooperation with European industry, making it a transatlantic industrial collaboration between the United States and Europe. Lockheed Martin works with a wide network of European suppliers, notably Kongsberg Defence & Aerospace (KDA). KDA participated in the production of the first TPY-4 radar and was responsible for the Platform Electronics Subsystem. More recently, KDA also assembled the first TPY-4 unit produced by an international industrial partner.
TPY-4 use in the Nordic countries
Denmark’s adoption of the TPY-4 fits within a broader regional trend. Norway confirmed, through the Norwegian Defence Materiel Agency (NDMA), the purchase of three additional TPY-4 radars, bringing its total fleet to 11 systems. In Norway, the radar has been referred to as “NATO’s eyes in the north,” highlighting its role within the Alliance’s air surveillance network. The system was also previously selected by the U.S. Air Force (USAF) and is supported by local suppliers, again including Kongsberg Defence & Aerospace.
Sweden, for its part, formalized the acquisition of TPY-4 radars through the Swedish Defence Materiel Administration (FMV). The contract stipulates that initial deliveries will take place in 2027, as part of Sweden’s effort to modernize its air surveillance, detection, and air defense capabilities. The system is NATO-compatible and allows for direct integration with systems currently in service with the Swedish Armed Forces, a particularly relevant factor following Sweden’s accession to the Alliance.
In the context of this acquisition, Rick Cordaro stated on June 4: “We are honored to support the defense and security of our allied nations. The TPY-4 radar represents a significant advancement in integrated deterrence, enhancing interoperability with NATO allies. As a trusted partner to the U.S. Air Force, Norway, and now Sweden, we are committed to delivering this advanced radar capability to help address the complex and evolving threats facing the United States and its allies.”
With Denmark’s selection of the TPY-4, the Nordic countries are consolidating a shared approach to air surveillance and defense, reinforcing regional interoperability and the framework of collective security within NATO.
