The C-5 Galaxy Weighs 838,000 When Loaded
42. When loaded, the C-5 Galaxy weighs 838,000. Well over double its empty weight. To be able to handle such a large weight rating. It is all thanks to the massive engines. Four General Electric TF39-GE-1C turbofan engines, rated at 41,000 pounds (183kN) of thrust each, mounted on pylons under the wings power the C-5 Galaxy. Now that is impressive.
