About the C-5 Galaxy and C-5M:





The Lockheed Martin C-5 Galaxy is a heavy military transport aircraft. It is the largest aircraft in the U.S. armed forces' inventory. Using the front and rear cargo openings, the C-5 Galaxy can be loaded and off-loaded at the same time. Both nose and rear doors open the full width and height of the cargo compartment.

The C-5 Galaxy routinely carries 73 troops and 36 standard 463L pallets. The aircraft is able to carry two M1 Abrams main battle tanks, or one Abrams tank plus two M2/M3 Bradley fighting vehicles, or six AH-64 Apache/Apache Longbow attack helicopters. Also, the C-5 is able to carry as many as 15 HMMWV (humvees).

The C-5 fleet (A, B, and C models) was delivered to the U.S. Air Force from 1969 to 1989. In total, 131 aircraft were produced. The Air Force plans to retire 59 C-5A aircraft, leaving a total of 52 C-5M aircraft. There were 102 aircraft in the USAF C-5 inventory as of January 2012. By September 2013, the inventory had fallen to 72.

The latest configuration is the C-5M Super Galaxy, which is equipped with more powerful General Electric CF6-80C2 (F138-GE-100) turbofan engines, each (4 total) providing 50,580 pounds of thrust. The older C-5A/B/C models are powered by four General Electric TF39-GE-1C turbofan engines with 43,000 pounds of thrust each.

The U.S. Department of Defense (DoD) C-5 modernization program, which will upgrade older C-5s to the C-5M configuration, provides greatly improved reliability, efficiency, and maintainability and thus, reduces operating costs and enables the C-5 to remain in service with the U.S. Air Force well into the 21st century (estimate is 2040 and beyond). The C-5M Super Galaxy is the result of a two-phase modernization effort featuring the Avionics Modernization Program (AMP) and the Reliability Enhancement and Re-engining Program (RERP).

The AMP installs a cutting-edge glass cockpit with a digital all-weather flight control system and autopilot; a new communications suite; flat-panel displays; and enhanced navigation and safety equipment. Enhancements such as the integrated datalink capabilities, predictive flight performance cues, and situational awareness displays (the Enhanced Ground Proximity Warning System) greatly enhance situational awareness and reduce crew workload.

The RERP installs new General Electric CF6-80C2 turbofan engines (+22% thrust) and provides for 70 other enhancements to major components and subsystems. The RERP significantly improves reliability, maintainability, operational performance, and fuel efficiency (8−20% reduction in consumption); and dramatically reduces operating costs.

The C-5M Super Galaxy has a 58% faster climb rate, a 30% shorter takeoff roll, and a 30% higher cruise than the current C-5 (A, B, and C models). This allows the C-5M to carry significantly more cargo from more airfields, over greater distances, and with reduced dependency on aerial refueling.

In June 2014, C-5M #19 was delivered to Dover Air Force Base (AFB) in Delaware. Lockheed Martin is expected to complete its work on the last of 52 C-5Ms in early 2018.

On June 18, 2014, the Air Force awarded Lockheed Martin a $223 million contract to upgrade C-5 Galaxy transports to the C-5M configuration. The new contract supports RERP upgrades for 11 C-5s.



Mission/Role:

The C-5 aircraft is a heavy cargo transport aircraft designed to provide strategic inter-theater airlift for deployment and supply of combat and support forces. It can carry fully equipped combat-ready troops to any area in the world on short notice and provide full field support necessary to maintain a fighting force.



FY 2014 DoD Program:

Continues upgrading the C-5 fleet to the C-5M Super Galaxy configuration. The Reliability Enhancement and Re-engining Program (RERP) is the primary FY 2014 modernization program for the C-5 Galaxy. Procurement funds in the amount of $1,052.6M have been allocated to the C-5.



FY 2015 DoD Program:

Modifications in FY 15 include the C-5 Fleet Blk Upgrade 01 and the C-5 Mission Systems Equipment upgrade. Continues upgrading the C-5 fleet to the C-5M Super Galaxy configuration. The Reliability Enhancement and Re-engining Program (RERP) is the primary FY 2015 modernization program for the C-5 Galaxy. Procurement funds in the amount of $346.2M have been allocated to the C-5.
