United Nations Space Fleet

The United Nations Space Fleet was created with the intent to protected the people of Terra and its colonies from any threat in the cosmos, be it solar or extra-solar. For the first 30 years of its life the UNSF was seen by many as a waste of government money and having no real value besides acting as piracy control in Terran territories. However, the Cold War between the United Nations and the Martian Confederacy changed the minds of many.

The possibility of a war in space became a very real threat by the mid 2100s, and the UN was not going to be caught off guard by the Martian Confederacy. During the Space War from 2179 to 2195, the United Nations Space Fleet grew to its largest recorded strength and those that made up its ranks continued to show their mettle as the UNSF fought the MCN back to their home planet. As the Space War, the United Nations Space Fleet decreased in both size and power, as it was mainly used to keep the peace in the colonies of Terra. As of 2267, the UNSF is still the largest operating space force in the Sol System.

From the its founding in the late 21st century until the outbreak of the UN v. MC Cold War in 2132, the UNSF sought to keep the space occupied by the United Nations safe for all those who lived in it. However, the UNSF never fielded any spacecraft larger than what would be considered a destroyer today, as they had no need for the warships that became common before and during the Space War. The most prevalent vessels deployed by the UNSF during the pre-Cold War were those of the Eagle-class, all of which were either sold or scrapped during the build up before the Space War.

The Space War, which took place between 2179 and 2195 CE, was the peak of UNSF's size and strength. Large 3rd and 4th generation spacecraft were fielded, such as the iconic Nation-class destroyer, as well as some of the largest military vessels seen in the Sol System, namely the 3 Freedom-class battleships. Only the Martian Confederacy's Ares-class battleships were larger. The total active personnel in the UNSF topped out at over 2.58 million in 2192, with over 4 million reserve personnel carrying out logistics and support for those in active service.

With the signing of the Tycho Treaty at the end of the Space War, the United Nations Space Fleet was decreased to only a third of its former operational size. Many of the warships that were used during the war were also scrapped in the years after its conclusion. Both of these were effects of the stipulations that the Tycho Treaty outlined, specifically the sections that detailed the scope of a nation's space force. However, the Unity-class Battleships have seemingly been exempt from the stipulations within the Treaty.
