The Medea was a class of transport plane used by the Earth Federation Forces. Loading and unloading time has been reduced by using a large detachable cargo container underneath the main body. The Medea's considerable capacity made it suited for supplying the frontlines. Its low-pressure tires allowed it to land on irregular surfaces, and it featured rotors which granted it VTOL capability, enabling it to take off and land without a runway. The Medea was initially used to transport cargo, but during the One Year War its cargo container was increasingly used to transport multiple mobile suits, which could be airdropped. The Medea was minimally armed with a pair of anti-air machine guns, which provided little means of self-defense.

The Medea Transport Plane was used by the Earth Federation throughout the One Year War and beyond. During the war, they were utilized to carry supplies and eventually mobile suits to all corners of the World, making the Medea a vital resource to their war effort.
