The Earth Federation Space Force

The Earth Federation Space Force (or EFSF for short) is the branch of the Earth Federation Forces created to enforce the edicts of the Earth Federation Government in space.

The Earth Federal Space Force was created to counter the percived military threat from the then Republic of NEO, which had broken away from the Federation when it declared independence. This branch of the armed service is almost exclusively concerned with space combat, and before the One Year War this branch was listed under the other three branches (Earth Federal Army, Earth Federal Navy, Earth Federal Air Force) and was commanded by generals appointed by those three. For example, General Arcturus was a Lieutenant General or Chujo of the EF Army.

When it was originally created the Federation's Space Force was a mirror image of the "Big Gun" ship philosophy, embodying powerful guns to destroy its enemies. This began to change in UC0079, when the NEO introduced their battle mechs, which thoroughly decimated the Federation's Space Force. The advent of the battle mech forced the Federation to develop their own mechs and ships that could carry them, resulting in the Pegasus-class MS carriers.

A handful of the Earth Federal Space Force ships were designed to withstand atmospheric re-entry and to operate on Earth; these ships Are from Pegasus class.
