The U.S. Air Force Three-Dimensional Expeditionary Long Rang Radar (3DELRR) program team and Lockheed Martin successfully accomplished risk reduction testing for the TPY-4 radar. TPY-4 is a multi-mission, ground-based radar for air defense surveillance that can operate in contested electromagnetic environments and provides the warfighter an ability to detect and track current and emerging threats. Gallium Nitride (GaN) technology in the system also provides greater efficiency and improved reliability as compared to legacy systems. This event demonstrated the radar’s performance in a variety of conditions. The 3DELRR program is of the utmost importance to air surveillance worldwide, as well as defending the homeland.
“This testing milestone is another accomplishment toward 3DELRR deliveries. These milestones are generating interest from several other government organizations,” said Chandra Marshall, vice president of Lockheed Martin Radar and Sensor Systems. “The collected data will play a role in optimizing performance of the system, bringing it one step closer to a fielded capability for the warfighter.”
A Hanscom team has selected the Lockheed Martin Corp.’s long-range radar in support of the Air Force’s Three-Dimensional Expeditionary Long-Range Radar, or 3DELRR, Rapid Prototyping program. Following the “SpeedDealer” radar demonstrations in the summer of 2020, and recent Air Force contract efforts in 2021 and 2022, the Air Force selected Lockheed Martin’s AN/TPY-4(V)1 to replace the TPS-75 radar. Pending the fiscal year 2022 appropriations bill, the program expects to exercise options for the initial radars. At this time, the Air Force only intends to enter production with Lockheed Martin. The program office in partnership with Lockheed Martin are fully committed to the successful deployment of 3DELRR systems and look forward to seeing the TPY-4 radar in the field.
With broad and deep experience developing and delivering advanced radar solutions to customers, Lockheed Martin’s high-performing, highly reliable radar systems specialize in providing advanced early warning, counter target acquisition, situational awareness, and integrated air and missile defense. Lockheed Martin radars are designed with a high degree of commonality, are available in highly mobile configurations, operate in all environments, and are deployed worldwide. It’s why Lockheed Martin’s radars are the choice of more than 45 nations on six continents. 3DELRR is a branch of the Theater Battle Control Division, a division of the Air Force Life Cycle Management Center’s Digital Directorate, headquartered here.
