What Will Lockheed Martin Provide?
The Department of War said Monday the cost-plus-fixed-fee and firm-fixed-price, indefinite-delivery/indefinite-quantity contract covers software updates and maintenance for the C-5 Galaxy. Lockheed Martin will also provide certification artifacts, systems integration laboratory maintenance, engineering and technical support and software engineering services.
What Are the Contract Details?
Lockheed will perform the work in Marietta, Georgia, and Greenville, South Carolina, through May 20, 2032. The Air Force selected the company through a sole-source acquisition. It obligated $19.3 million in fiscal 2026 operation and maintenance funds at the time of award. Robins Air Force Base’s C-5 Contracting Branch in Georgia is the contracting activity.
How Does the Award Build on Previous C-5 Work?
The latest contract continues Lockheed Martin’s long-standing support of the Air Force’s C-5 fleet. In June 2025, the company received a $56 million contract to support the C-5M Super Galaxy avionics modernization program and to provide sustainment and logistics services for the aircraft’s reengining effort. Earlier awards included a potential $129.4 million logistics support contract in 2021 and a $131.6 million sustaining engineering contract in 2019.
