The Department of Defense, specifically the Department of the Air Force, is soliciting proposals for the Universal Armament Interface (UAI) program, aimed at continuing the development and sustainment of a universal armament interface applicable across various weapon-carrying platforms and munition systems. This procurement is intended to be awarded on a sole source basis to the four Original Equipment Manufacturers (OEM) — Boeing, Lockheed Martin, Northrop Grumman, and Raytheon — under the authority of Title 10 U.S.C. 3204(a)(1) and 41 U.S.C. 3304(a)(1), emphasizing the need for a single responsible source to meet agency requirements. The UAI program is crucial for standardizing data interfaces in response to advancing technology and emerging weapon systems, with the contract type expected to be a combination of Cost Plus Fixed Fee (CPFF), Cost Reimbursement (CR), Time and Materials (T&M), and Hybrid arrangements. Interested parties may submit capability statements or proposals for consideration, and for further inquiries, they can contact Lisa Matthews at lisa.matthews.1@us.af.mil or Lakeisha Washington at lakeisha.washington.1@us.af.mil.
