The Department of Defense, specifically the Department of the Air Force, is seeking to award a sole source contract for Gartner subscriptions and licenses to provide research and advisory services for the Strategic Warning and Surveillance Systems Acquisition Delta (SSC/SZQ). This procurement is justified as market research indicates that Gartner is the only provider capable of delivering the specific services required, with no authorized resellers available for the associated licenses. The contract will be executed under Gartner's DoD ESI Blanket Purchase Agreement (BPA) N66001-19-A-0049, and interested parties can direct inquiries to Kevin Sibley at kevin.sibley@spaceforce.mil. The place of performance for this contract will be in Colorado Springs, CO, with the relevant PSC code being B544 for special studies and analysis in technology.
