Guam Defense System (GDS) Request for Solutions Brief (RFSB)

The U.S. Army Portfolio Acquisition Executive (PAE) Fires is seeking solutions for the Guam Defense System through a Request for Solutions Brief (RFSB) under solicitation number MOSAIC-26-04, issued under the authority of 10 U.S.C. § 4022 for an Other Transaction Agreement for Prototype purposes. Only U.S.-based companies capable of handling and storing SECRET-level information and hardware are eligible to respond. The RFSB was initially posted on July 2, 2026, with an updated revision (REV 02) released on July 14, 2026, and the submission deadline has been extended to 9:00 a.m. EST on July 20, 2026, with the official response deadline set for 1:00 p.m. EDT on the same date. The solicitation is managed by the Department of Defense through the W6J1 Rccto Redstone office located at Redstone Arsenal, Alabama, with primary point of contact Sydney Horn and secondary contact Barbara Cantrell available for inquiries. The North American Industry Classification System code for this effort is 541715, indicating it is related to research and development in the physical, engineering, and life sciences. Although key sections such as evaluation criteria, deliverables, pricing, contract clauses, and special requirements are not available due to technical retrieval failures, the intent is clearly to establish a prototype agreement to advance defense capabilities for Guam, with CUI Q&A materials distributed to all vendors via DoD SAFE. No contract value estimate or set-aside information is provided, and no packaging, inspection, or performance specifications are detailed in the available materials.
