Lockheed Martin has won a $36 million contract from the USAF for the next part of its Three Dimensional Expeditionary Long Range Radar (3DELRR) program. The 3DELRR is intended to serve as the principal long-range, ground-based sensor for detecting, identifying, tracking, and reporting aerial targets for the Air Force. The system, which will replace the AN/TPS-75 air surveillance radar, will be capable of detecting new, emerging air defense threats and managing challenging battlefield air control scenarios out to extended ranges. Under the Pre-Engineering and Manufacturing Development (Pre-EMD) Period of the Technology Development Phase, the Air Force is expected to review industry trade studies to help set final radar requirements, conduct preliminary design reviews, and demonstrate radar system-level technology maturity. At the end of this 15-month phase, the Air Force is expected to award an EMD and low-rate production contract. "We need to give battlefield commanders the most response time possible to detect and prosecute emerging threats. Only advanced technology long-range radar like 3DELRR can do that," said Mark Mekker, director of ground-based surveillance radar for Lockheed Martin's Mission Systems & Sensors business. "Our 3DELRR technology is mature, focused on not just performing now, but evolving and extending system life as required. We can offer that radar to the U.S. Air Force today".
