The Defense Health Agency (DHA), on behalf of the United States Air Force 59th Medical Wing, intends to award a sole source contract to KBR Wyle Services, LLC for research and development services related to the study titled "Mechanisms of Radiofrequency (RF) Interaction with Biological Systems." This contract focuses on investigating the biomedical effects of high-power microwave overexposure in Yucatan miniature swine, leveraging KBR's extensive prior involvement and expertise in the project. The sole source award is justified under FAR 6.302-1(a)(2)(iii)(A), as awarding to another entity would result in substantial unrecoverable duplication of costs. Interested parties who believe they can provide these services must submit written evidence of their capabilities by January 6, 2026, at 12:00 PM EST, or the contract will proceed as planned with KBR. For further inquiries, interested parties may contact James Clingan at james.b.clingan.civ@health.mil or Jeremy McMurry at jeremy.l.mcmurry.civ@health.mil.
