The Lockheed C-5 Galaxy is a large military transport aircraft designed and built by Lockheed, and now maintained and upgraded by its successor, Lockheed Martin.It provides the United States Air Force (USAF) with a heavy intercontinental-range strategic airlift capability, one that can carry outsized and oversized loads, including all air-certifiable cargo.

Lockheed submitted both a C-5-based design and an enlarged C-141 design. On 28 August 1981, McDonnell Douglas was chosen to build its proposal, then designated C-17 . Compared to the YC-15, the new aircraft differed in having swept wings, increased size, and more powerful engines. [ 6 ]
Military transport helicopters are used in places where the use of conventional aircraft is impossible. For example, the military transport helicopter is the primary transport asset of US Marines deploying from LHDs and LHA.
The General Electric TF39 is a high-bypass turbofan engine that was developed to power the Lockheed C-5 Galaxy. The TF39 was the first high-power, high-bypass jet engine developed. The TF39 was further developed into the CF6 series of engines, and formed the basis of the LM2500 and LM6000 marine and industrial gas turbine. On September 7, 2017 ...
The Lockheed C-5 Galaxy was considered for the shuttle-carrier role by NASA but rejected in favor of the 747. This was due to the 747's low-wing design in comparison to the C-5's high-wing design, and also because the U.S. Air Force would have retained ownership of the C-5, while NASA could own the 747s outright.
Air transportability will be by fixed-wing aircraft as large or larger than the Lockheed C-130 Hercules and sling-loadable with rotary-wing aircraft such as the CH-47/MH-47 Chinook and Sikorsky CH-53 Sea Stallion. The proposed ambulance variant was to be air-droppable by Lockheed C-5 Galaxy and Boeing C-17 Globemaster III fixed-wing aircraft. [48]
