The C-5 Galaxy produced by Lockheed had its origins in the early 1960's as a larger replacement for existing aircraft.
In 1965 Lockheed was awarded the contract for the aircraft. On June 30, 1968 the first C-5 Galaxy took to the sky. They began deployment in 1970.
The front and rear cargo doors of the Lockheed C-5 Galaxy allow drive through aircraft loading and unloading. Its landing gear can be adjusted to lower the floor of the cargo area by approximately 10 ft. from normal height. This facilitates the loading of cargo by lowering the height of the cargo floor to only half the normal distance from the ground. It also keeps the incline angle of the aircraft ramps at a minimum.
The ailerons of the C-5 Galaxy are computer controlled to move automatically in order to counter wing flexing that can occur during flight. The aircraft is completely pressurized and is capable of in flight refueling.
A twenty eight wheel landing gear permits wider load distribution for rough runway operations. The fuselage mounted landing gear can operate each wheel set separately. This facilitates maintenance. The landing gear system can be angled up to twenty degrees to facilitate cross wind landings and take offs.
The aircraft has four electrical generators and two auxiliary power units, a triple redundancy GPS navigation system, computerized aircraft systems analysis, monitoring and recording.
C-5 Galaxy aircraft participated in airlifts late in the Vietnam War. Taking off from the Azors, the aircraft help supply Israel with tanks and other weapons during the 1973 war with Syria and Egypt. They also delivered supplies to earthquake victims in Armenia during December of 1988. In March of 1989 the aircraft delivered two million lbs. of supplies for clean up of the Alaska oil spill. They participated in Desert Shield, Desert Storm and the 2003 U.S. invasion of Iraq.
In 2006 Lockheed began the upgrading of C-5 Galaxy aircraft with Versatile Integrated Avionics/Avionics Integrated Units (VIA/AIU). The VIA software system has six primary “partitions” or applications that include flight management, com/nav/surveillance/identification (CNSI), communication management, display services and all-weather flight control. A Core Mission Computer/Weather Radar replaces the weather radar with a commercial off-the-shelf color weather radar. In addition to the new avionics, the aircraft have more efficient, powerful engines, fuselage enhancements, increased carrying capacity, range, and performance. The upgraded aircraft are designated C-5M Super Galaxy.
During testing in September, 2009, a Super Galaxy set numerous new records for its class regarding cargo loads and record times to flight ceilings.
On Feb. 12, 2020 the U.S. Air Force Life Cycle Management Center awarded Canadian Commercial Corp., Ottawa, Canada, US$225 million to provide the Air Force with "the depot repair support required for the F138 engine and components". F138 engines propel C-5 Galaxy model M Super Galaxy aircraft. Work will take place in Richmond, British Columbia, and should be finished by Feb. 11, 2030.
On July 14, 2020 the The U.S. Air Force Sustainment Center awarded Thomas Instrument, Brookshire, Texas, US$7,100,000 "for the depot-level overhaul of the C-5 Galaxy visor door actuator". Work should be finished by July 13, 2025.
A total of over 130 C-5 Galaxy aircraft of all types have been produced.
