Sweden Chooses Lockheed Martin’s AN/TPY-4 Radar to Boost Air Surveillance Capabilities

Sweden is set to enhance its long-range air surveillance with the acquisition of Lockheed Martin’s AN/TPY-4 next-generation radar system, the company announced on June 4, 2025. The selection was made by the Swedish Defence Materiel Administration (FMV) as part of ongoing efforts to modernize and strengthen national air defense.

With this move, Sweden becomes the third nation—following the United States and Norway—to adopt the advanced ground-based radar system.

While the full terms of the agreement were not made public, Lockheed Martin confirmed that the first AN/TPY-4 radars will be delivered to Sweden in 2027.

A Leap in Detection Capabilities

The AN/TPY-4 is an L-band, 3D surveillance radar that utilizes gallium nitride (GaN)-based active electronically scanned array (AESA) technology to deliver powerful detection across a wide range of targets—from low-flying drones to high-altitude ballistic missiles.

Key operational modes include:

• Rotating mode (6 RPM) with 360° coverage and a 555 km detection range
• Stop-and-stare mode for focused tracking with a range of up to 1,000 km

These capabilities offer enhanced situational awareness and early warning performance, critical for national and regional defense in an increasingly complex airspace.

Designed for Seamless Integration

According to Lockheed Martin, the AN/TPY-4’s open-architecture design allows for easy integration with existing Swedish air defense systems and enhances interoperability with NATO forces and regional partners. This aligns with Sweden’s growing role in European defense cooperation and its path toward NATO integration.

“We are honoured to support the defence and security of our allied nations,” said Rick Cordaro, Vice President of Radar and Sensor Systems at Lockheed Martin. “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.”
