C-5B GALAXY Inter-Theater Airlift Aircraft

The C-5B GALAXY Inter-Theater Airlift Aircraft program is a Major Defense Acquisition Program (MDAP) managed by the Department of Defense under the Major Capability Acquisition pathway. This program oversees the sustainment, maintenance, and modernization of the C-5B Galaxy strategic airlift aircraft fleet. The program's scope encompasses both aircraft systems support and ground support equipment maintenance to ensure continued operational capability of this strategic airlift platform.

The federal contract awards associated with this program primarily consist of Contractor Logistics Support (CLS), component repairs, structural maintenance, and spare parts procurement. Contract values range from small purchases of several hundred dollars for individual components to multi-million dollar awards exceeding $9 million for comprehensive structural repairs. Lockheed Martin Aeronautics Company and BAE Systems are notable prime contractors for major systems support, while numerous small businesses participate through various set-aside designations, particularly Service-Disabled Veteran-Owned Small Business and Total Small Business set-asides. The Air Force Materiel Command (AFMC) is the predominant contracting authority, typically issuing firm-fixed-price delivery orders with performance periods ranging from several months to multiple years. Contract vehicles include both standalone purchase orders for specific components and longer-term Indefinite Delivery/Indefinite Quantity (IDIQ) contracts for ongoing maintenance and logistics support.
