The U.S. Air Force Test Center at Edwards AFB, CA, intends to award a single-source contract to Marvel Aero International Inc. to upgrade Aircraft Battery Management System (ABMS) hardware and software to an ABMS-10X station. This action is justified by proprietary software architecture, the need to interface with existing branded charging hardware, and safety/warranty risks from uncertified third-party controllers. The government believes Marvel Aero is the only responsible source capable of meeting this requirement, and full competition would result in incompatible equipment. Interested parties may submit questions and feedback by 11:30am PDT on 01 August 2026. No budget amount or performance location beyond Edwards AFB is specified.
