The newer C-5M Super Galaxy has the F-138 GE engines, which unfortunately for aviation fans, don't sound quite as good, and the thrust reversers don't make the same creepy sounds either.
Power Plant: Four General Electric TF-39 engines (C-5A,B,C) Four F-138 General Electric engines (C-5M)
Thrust: 43,000 pounds, each engine (C-5A,B,C)/ 51,250 pounds, each engine (C-5M)
Wingspan: 222 feet 9 inches (67.89 meters)
Length: 247 feet 1 inch (75.3 meters)
Height: 65 feet 1 inch (19.84 meters)
The C-5 Galaxy is one of the largest aircraft in the world and the largest airlifter in the US Air Force inventory. The aircraft can carry a fully equipped combat ready military unit to any point in the world on short notice and then provide the supplies required to help sustain the fighting force.
The new C5M's F-138 GE engines deliver a 22 percent increase in thrust, a 30 percent shorter take-off roll, has a 58 percent faster climb rate and will allow significantly more cargo to be carried over longer distances. With its new engine and other system
upgrades, the RERP modified C-5A/B/Cs become C-5Ms, Super Galaxy.
This modernization program will make the C-5 much quieter and
enhance aircraft reliability and maintainability, maintain structural and system integrity, reduce cost of ownership and increase operational capability.
