Modification, Maintenance, Repair and Overhaul (MMRO)

Lockheed Martin is committed to providing affordable airframe, engine and component maintenance to our customers around the globe. We provide cost-effective solutions with long-term benefits tailored to individual customer requirements. Partnering with our customers does not end when we deliver their aircraft – we are partners for the life of the aircraft, ensuring they maintain the aircraft availability and mission capable rates they require.

To achieve this, we provide proven engine and structural modification, maintenance, repair and overhaul (MMRO) services. We respond rapidly to our customers’ needs and are backed by the proven original equipment manufacturer expertise of Lockheed Martin Aeronautics Company.

Our proven MMRO capabilities and programs include:

Aviation Services

Lockheed Martin offers “nose-to-tail” aircraft maintenance, modifications and state-of-the-art upgrades for aircraft built by Lockheed Martin and other manufacturers. 

Our Technical Service Center in Greenville, S.C., has a highly experienced workforce that provides quality Original Equipment Manufacturer (OEM) sustainment services, including program depot maintenance, modification upgrades such as paint and kitting, on-site production and engineering reach-back that produce quality results in less time.

The C-5 modernization program provides greatly improved reliability, efficiency, maintainability and availability, while ensuring this critical national strategic airlift resource continues serving the warfighter well into the 21st century. The C-5M Super Galaxy is the result of a two-phase modernization effort: the Avionics Modernization Program (AMP) and the Reliability Enhancement and Re-engining Program (RERP). More than 70 aircraft improvements have been made, including new engines, a state-of-the-art glass cockpit, cargo improvements and built-in controls and diagnostic systems.

The P-3 Mid-Life Upgrade (MLU) Program consists of a life extension kit that replaces all fatigue-life-limiting structures with enhanced-design components, including the aircraft outer wings, center wing lower section and horizontal stabilizer with new production components and a new metal alloy that is five times more corrosive resistant than the existing material. The MLU removes current aircraft flight restrictions and extends the structural service life of the P-3 Orion up to 15,000 hours, adding more than 20 years of operational use.

Engine Services

Lockheed Martin Commercial Engine Solutions provides engine maintenance, repair and overhaul for military and commercial customers through a unique set of partnerships at the facilities in San Antonio, Texas, and Montreal, Canada. Between the two sites, Commercial Engine Solutions offers engine MRO, test and back shop repair services for ten military and commercial jet engine lines, including the CF6, CF34 and CFM56 engine families as well as the power plants for F-16 and F-15 fighters.

Field Team Operations

Field Team Operations (FTO) is an agile, low-cost logistics solution designed to support both Lockheed Martin and external customer aircraft requirements. FTO's ability to mobilize field service teams quickly and efficiently leverages Lockheed Martin resources to provide complete sustainment solutions for our customers that aircraft availability rates.

Whether co-located in your facilities or providing support from our own world-class sites, our employees are committed to offering proven technical solutions that help customers achieve mission success.
