Sweden selects Lockheed Martin’s AN/TPY-4 air surveillance radar

The Swedish Defence Materiel Administration (FMV) has selected the AN/TPY-4 next-generation ground-based air surveillance radar to enhance the country’s long-range surveillance capability, manufacturer Lockheed Martin announced on 4 June 2025.

Sweden thus becomes the third country to select the AN/TPY-4 after the United States and Norway.

Lockheed Martin did not disclose the full details of the contract, but stated that it will deliver the first AN/TPY-4 radar systems to Sweden in 2027.

The AN/TPY-4 is an L-band, 3D radar that uses a gallium nitride-based active electronically scanned array to detect air targets from low-profile unmanned aerial vehicles to ballistic missiles. It can rotate at six revolutions per minute to give 360° coverage, when it has a range of 555 km, or can operate in stop/stare mode, when it has a range of 1,000 km.

Lockheed Martin states that its “cutting-edge technology and open-architecture design enable seamless integration with existing air defence systems, strengthening interoperability between the Swedish armed forces, regional partners and NATO allies”.

“We are honoured to support the defence and security of our allied nations,” Rick Cordaro, vice president of Radar and Sensor Systems at Lockheed Martin, was quoted as saying in a company press release. “The TPY-4 radar represents a significant leap forward in integrated deterrence, enhancing interoperability with NATO allies. As a trusted partner to the US Air Force, Norway and now Sweden, we are committed to delivering this advanced radar capability to help address the complex and evolving threats faced by America and its allies.”
