The Department of Defense, specifically the U.S. Army Engineer Research and Development Center (ERDC), is inviting submissions for prototype concept white papers under the Broad Other Transaction Authority Announcement (BOTAA) focused on Military Engineering and Engineered Resilient Systems. This initiative aims to address significant challenges in military engineering through innovative research and development, with white papers being accepted and evaluated continuously throughout the year. The BOTAA represents a competitive opportunity for entities to contribute to critical military engineering solutions, although funding availability may influence award decisions. Interested parties can find more information and submission guidelines at ERDCWERX and should direct inquiries to Allison Hudson at allison.b.hudson@usace.army.mil.
