This update, which went into service in 2009, features upgraded engines, contemporary avionics, and strengthened systems. The C-5M Super Galaxy is an example of adaptable design, bringing modern technology to a platform that dates back to the 1970s. Its enormous cargo bay is large enough to hold helicopters and war vehicles alike.
