TPY 4 RADA Multi Mission Air Defense Radar

The TPY-4 is Lockheed Martin’s next generation ground based air surveillance radar, developed to strengthen national and NATO integrated air and missile defense networks. Designed to replace aging Cold War era sensors, TPY-4 delivers persistent, long range detection against modern air threats, including aircraft, cruise missiles, and unmanned aerial systems. Its fully digital AESA architecture allows continuous 360 degree coverage while supporting high target density environments.

Selected by Denmark to reinforce NATO deterrence and regional air defense, TPY-4 reflects Lockheed Martin’s focus on scalable, networked sensors optimized for coalition operations and U.S. aligned command and control systems.

Manufacturer

TPY-4 is manufactured by Lockheed Martin, a U.S. based defense and aerospace company. The radar is developed and produced in the United States, with European industrial participation for selected international programs. Lockheed Martin is responsible for system design, radar technology, software, and integration.

Speed and Range

AN/TPY-4 provides detection ranges of up to 450 kilometers against large aerial targets. The radar supports high update rates and simultaneous tracking of hundreds of targets, including high speed and low altitude threats. Electronic beam steering enables rapid repositioning without mechanical movement, improving survivability and reaction time.
