The Horizon-class was a type of early Earth/Federation exploration starship in service from 2150 to 2197*. Classified as a Cruiser, they were originally launched with laser-based weapons and defenses. At the commencement of open hostilities in the Earth-Romulan War, the weapons were upgraded in order to increase their combat performance. Following the war, they continued in service following the incorporation of the United Federation of Planets.
Their Second Generation Warp Drive system was centered around an antimatter spiked fusion drive utilizing a ratio mix of 20:1 matter/antimatter for a maximum speed of warp 3.25 (34.2 C).
The Horizon Class was one of the most important ships and classes in spaceflight history. The flagship for early United Federation of Planets space exploration, the USS Horizon journeyed to the edge of the galaxy, encountering many new worlds in its numerous voyages. At the end of its commissioned life, it was retired to Star Fleet's Spaceflight Museum on Memory Alpha.(TOS reference: Spaceflight Chronology)
