C-5 Reliability Enhancement and Re-engining Program

The C-5 Reliability Enhancement and Re-engining Program (C-5 RERP) is a Major Defense Acquisition Program (MDAP) under the Major Capability Acquisition (MCA) pathway, designated as Acquisition Category IC. The program supports the sustainment and modernization of the U.S. Air Force's C-5 Galaxy strategic airlift aircraft fleet through contracted logistics support, engineering services, and technical upgrades. This comprehensive program encompasses maintenance, repairs, software updates, spare parts management, and modifications to ensure continued airworthiness and mission capability of the C-5 platform.

The majority of contract awards under this program are delivery orders issued by the Air Force Materiel Command, primarily through the Life Cycle Management Center at Robins Air Force Base. Lockheed Martin Corporation, through its Aeronautics Company division in Marietta, Georgia, serves as the primary contractor for Contractor Logistics Support (CLS) services under cost-plus-fixed-fee and fixed-price-incentive delivery orders ranging from several thousand to several million dollars, with performance periods typically spanning 12-36 months. Other significant contractors include Honeywell International Inc., providing sustainment engineering support from facilities in Phoenix, Arizona and Albuquerque, New Mexico, with contract values in the $2-6 million range, and Advanced Project Consulting, LLC, delivering engineering review and technical documentation services. Notable subcontractors include General Electric Company's GE Aviation division for thrust reverser components and Scioteq BV (formerly Esterline Belgium) for control display units. The program predominantly utilizes unrestricted competition, with limited use of small business set-asides for specific technical support services.
