Norwegian Defence Materiel Agency Orders Additional TPY-4 Radars

The Norwegian Defence Materiel Agency (NDMA) has exercised an option to procure three additional TPY-4 radars from Lockheed Martin, increasing the total number of these ground-based multi-mission radars to eleven.

This move follows the recent completion of the Critical Design Review (CDR) for the TPY-4, which confirmed that the radar design meets the program’s requirements.

The TPY-4 radar system, described as a multi-mission sensor, enhances the Norwegian Air Force’s ability to detect, track, and classify aerial threats, thereby providing vital situational awareness. It supports various functions including air surveillance, unmanned aerial system (UAS) detection, ballistic missile defense, and air traffic control.

Lockheed Martin’s collaboration with Norwegian industry, particularly Kongsberg Defence & Aerospace (KDA), has been a key element in the development of the TPY-4. KDA contributed the Platform Electronics System (PES) for the radar, which is a fundamental component in meeting the long-range surveillance requirements of the system.

The TPY-4 radars will be managed and operated by the Royal Norwegian Air Force, which will integrate them into Norway’s broader air surveillance and defense network. With the CDR now completed, Lockheed Martin and KDA are focusing on finalizing production and preparing for the first Factory System Test (FST), scheduled for completion in 2025.

Additionally, the U.S. Air Force has selected the TPY-4 radar for its Three-Dimensional Expeditionary Long Range Radar (3DELRR) program and has conducted risk reduction testing.
