**Lockheed Martin Delivers First TPY-4 Radar to U.S. Air Force, Kicking Off 3DELRR Program Testing**

Lockheed Martin has delivered the first TPY-4 radar system to the U.S. Air Force following successful completion of early phase testing, marking a major milestone in the Three-Dimensional Expeditionary Long-Range Radar (3DELRR) program. The radar system, designed for high-performance air surveillance and missile defense, will now enter the government testing phase.

The TPY-4 features a fully digital, software-defined architecture capable of rapidly adapting to emerging threats, including those in jamming environments. It provides long-range early warning capabilities and is deployable in both fixed and mobile variants, with transportability across various platforms including aircraft, rail, and truck.

The delivery aligns with a broader radar acquisition contract awarded by the Air Force as part of its modernization efforts. Lockheed Martin’s radar systems are trusted by over 45 nations and are known for their reliability, mobility, and advanced threat detection capabilities.
