On June 4, 2025, U.S. company Lockheed Martin announced that the Swedish Defence Materiel Administration has selected the Lockheed Martin TPY-4 next-generation ground-based air surveillance radar to enhance the country’s long-range surveillance capability, making Sweden the third nation to adopt this fifth-generation radar platform.
The decision represents a strategic move by Sweden to bolster its airspace awareness and operational readiness as it deepens integration with NATO’s collective defense framework. Lockheed Martin will begin delivering the first TPY-4 radar systems in 2027 to support the Swedish Air Force’s national defense requirements. These advanced systems will be deployed to strengthen early warning capabilities and provide superior situational awareness in the face of increasingly complex aerial threats.
The TPY-4 radar is designed with a fully digital, software-defined architecture that allows it to adapt to emerging threats while operating in congested and contested electromagnetic environments. Its solid-state, active electronically scanned array (AESA) offers high reliability, rapid beam agility, and long-range detection of fast-moving targets such as cruise missiles, stealth aircraft, and drones. With real-time tracking and classification functions, it significantly increases the effectiveness of command and control decisions in critical moments.
